• Aging skin. Although there is interest in using oral or topical acai to prevent aging skin, there is insufficient reliable information about the clinical effects of acai for this purpose.
• Athletic performance. It is unclear if oral acai is beneficial for improving athletic performance. Details: Preliminary clinical research in amateur cyclists shows that consuming 400 grams of pasteurized acai pulp daily for 15 days prevents oxidative damage and decreases levels of blood lactate during exercise by 28% when compared with placebo. Consuming acai pulp also seems to increase anaerobic threshold intensity, but does not improve maximum workload or measures of exertion, when compared to baseline (102860).
• Erectile dysfunction (ED). Although there is interest in using oral acai for ED, there is insufficient reliable information about the clinical effects of acai for this condition.
• Hypercholesterolemia. Although there is interest in using oral acai for hypercholesterolemia, there is insufficient reliable information about the clinical effects of acai for this condition.
• Metabolic syndrome. Although there is interest in using oral acai for metabolic syndrome, there is insufficient reliable information about the clinical effects of acai for this condition.
• Obesity. It is unclear if oral black seed is beneficial for improving metabolic indices in overweight individuals. Details: In overweight individuals, preliminary clinical research shows that consuming 100 mg of acai pulp (Sambazon Acai Smoothie Pack, Sambazon Inc.) twice daily for one month reduces fasting glucose and total cholesterol levels when compared with baseline. However, no effect was seen on levels of low density lipoprotein (LDL) cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol, or blood pressure (17731). The validity of these findings is limited by the lack of a comparator group.
• Osteoarthritis. Although there is interest in using oral acai for osteoarthritis, there is insufficient reliable information about the clinical effects of acai for this condition.
• Tinnitus. It is unclear if oral acai is beneficial for chronic tinnitus. Details: A small clinical study in adults with unilateral or bilateral chronic tinnitus, with either normal hearing or mild hearing loss, shows that taking dried acai pulp extract 100 mg daily for 3 months decreases tinnitus discomfort when compared with baseline (107846). However, the validity of this finding is limited by the lack of statistical comparison to the placebo group, which reported a numerically similar improvement in tinnitus discomfort. More evidence is needed to rate acai for these uses.

• Age-related macular degeneration (AMD). It is unclear if oral goji berry reduces the risk of developing AMD. Details: A small, unblinded clinical study in healthy adults aged 45 to 65 years shows that consuming goji berries 28 grams five times a week for 90 days improves macular pigment optical density, which is a marker for AMD, when compared to baseline (110767). The validity of this finding is limited by the lack of statistical comparison to the other study group that received a supplement containing lutein and zeaxanthin.
• Cancer. Although there is interest in using oral goji for cancer, there is insufficient reliable information about the clinical effects of goji for this condition.
• Cardiovascular disease (CVD). It is unclear if oral goji improves risk factors for CVD. Details: A meta-analysis of 6 mostly small clinical studies of adults in China shows that consuming goji as polysaccharide extract or juice for 1-3 months modestly improves triglycerides, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and fasting blood glucose but does not impact total cholesterol when compared with no treatment or placebo (110765). Another meta-analysis of 4 small clinical studies in adults also shows that consuming goji polysaccharide extract or goji berries for 1-4 months modestly improves triglycerides and HDL but does not impact total or LDL cholesterol when compared with placebo or healthy eating. Goji also had no impact on systolic or diastolic blood pressure, or markers of oxidative stress (110768). However, the interpretation of the findings from these meta-analyses is limited by the use of variable goji forms and doses, as well as inclusion of studies in heterogeneous patients, including healthy people, patients with diabetes, and patients with metabolic syndrome. Furthermore, most studies were conducted in China; it is unclear if these benefits can be extrapolated to other geographic locations.
• Cognitive function. It is unclear if oral goji berry improves cognition in healthy young individuals. Details: A small clinical crossover study in healthy participants 14-24 years of age shows that taking goji berry fruit water extract (BIOMIX Company) 3600 mg in 3 divided doses daily for 4 weeks might improve certain cognitive measures such as verbal learning, short-term memory, and attention when compared with baseline (105488). The validity of these findings are limited due to incomplete outcome reporting and a lack of statistical comparisons between the treatment and placebo groups.
• Cough. Although there is interest in using oral goji for cough, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Depression. It is unclear if oral goji berry polysaccharide is beneficial for adolescents with subthreshold depression. Details: A small clinical study in adolescents aged approximately 15 years with subthreshold depression in China shows that taking goji berry polysaccharide extract 300 mg daily for 6 weeks modestly improves clinician-assessed depression scores (i.e. Hamilton Depression Scale, HAMD-24) but does not improve self-reported depression scores (i.e. Beck Depression Inventory) or scores assessing sleep quality, psychological distress, or anxiety when compared with placebo (110769). However, these results are from an interim analysis, which limits the interpretation of these findings. Furthermore, it is unclear if results can be extrapolated to patients in other geographic locations.
• Diabetes. It is unclear if oral goji berry polysaccharides improve glycemic control in patients with diabetes. Details: One small clinical study in patients with type 2 diabetes shows that taking goji fruit polysaccharide powder 150 mg twice daily for 3 months results in a slightly lower postprandial glucose area under the curve (AUC), but does not seem to affect insulin levels or insulin resistance, when compared with placebo. A subgroup of patients who were not taking antidiabetes medications had a greater reduction in postprandial blood glucose (92117).
• Dry eye. Although there is interest in using oral goji for dry eye, there is insufficient reliable information about the clinical effects of goji for this purpose.
• Erectile dysfunction (ED). Although there is interest in using oral goji for ED, there is insufficient reliable information about the clinical effects of goji for this condition.
• Hypertension. Although there is interest in using oral goji root bark for hypertension, there is insufficient reliable information about the clinical effects of goji for this condition.
• Obesity. It is unclear if oral goji berry juice improves weight loss. Details: Preliminary clinical research in healthy, overweight adults shows that drinking a specific goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14 days while following a weight loss diet and participating in an exercise program decreases waist circumference by about 4.7 cm more than exercise and diet alone. However, drinking goji berry juice along with diet and exercise does not improve body weight, body mass index, or body fat when compared with diet and exercise alone (52536).
• Quality of life. Small clinical studies suggest that oral goji berry juice may modestly improve quality of life in healthy adults. Details: Small clinical studies in healthy adults suggest that taking a specific standardized goji fruit juice (GoChi, FreeLife International LLC) 120 mL daily for 14-30 days improves subjective measures of energy levels, athletic performance, sleep quality, mental acuity, calmness, feelings of well-being, and gastrointestinal regularity when compared with placebo (17082,52532,52542). These studies were funded by the juice manufacturer.
• Sunburn. It is unclear if oral goji extract can prevent sunburn. Details: A small clinical study in healthy Japanese adults shows that taking goji extract 900 mg daily for 8 weeks reduces and accelerates resolution of erythema after exposure to a standard dose of UVB irradiation when compared with placebo (110770). All study participants were highly UV-sensitive; it is unclear whether these results can be extrapolated to individuals less sensitive to UV irradiation.
• Tinnitus. Although there is interest in using oral goji for tinnitus, there is insufficient reliable information about the clinical effects of goji for this purpose. More evidence is needed to rate goji for these uses.

• Periodontitis. Oral and topical mangosteen may modestly improve gum health. Details: A small clinical study in adults with chronic periodontitis shows that applying a gel containing mangosteen pericarp 4% to the periodontal pocket following scaling and root planing procedures improves pocket depth, clinical attachment, and bleeding by 56% to 63%, compared with a 33% to 42% improvement with placebo (97875). Another small clinical study in similar patients shows that applying mangosteen 4% gel to the periodontal pocket following scaling and root planning improves pocket depth and clinical attachment when compared with placebo. However, plaque and bleeding indices were not compared between groups (110126). A clinical study in patients with generalized or localized gingivitis or stage I periodontitis shows that taking 194 mg of a product containing mangosteen and propolis orally improves the modified gingival index by 31% or 40% at weeks 4 or 8, respectively, compared with 16% or 25% in those receiving placebo. No changes in probing depth, clinical attachment, plaque index, bleeding, or gingival recession were observed (106789). It is unclear if these effects are due to mangosteen, propolis, or the combination.

• Alzheimer disease. It is unclear if oral mangosteen is beneficial for patients with Alzheimer disease. Details: A small clinical study in adults with Alzheimer disease in Thailand shows that treatment with oral mangosteen pericarp extract, provided either as 220-280 mg daily for 24 weeks, or as 220-280 mg daily for 12 weeks followed by 440-560 mg daily for 12 weeks, does not consistently improve cognitive function scores to a clinically significant extent when compared with placebo. This study assessed cognitive function on the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Thai Mental State Examination (110127). However, the validity of this study is limited by poor methodology, including inadequate power and blinding.
• Androgenic alopecia. Mangosteen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large clinical trial in males and females with androgenic and diffuse alopecia shows that applying a hair lotion containing fermented mangosteen 2%, fermented papaya 2%, and caffeine 0.5% to the scalp daily plus use of a shampoo containing fermented mangosteen 0.5% and fermented papaya 0.5% 3 times weekly for 14 weeks improves hair shaft and root quality, hair diameter, and the density and percentage of thick hairs compared to baseline (111719). It is unclear if these effects are due to fermented mangosteen, other ingredients, or the combination.
• Atopic dermatitis (eczema). Although there has been interest in using topical mangosteen for eczema, there is insufficient reliable information about the clinical effects of mangosteen for this purpose.
• Muscle fatigue. It is unclear if oral mangosteen is beneficial in preventing muscle fatigue during physical activity. Details: A very small clinical study in healthy, physically active adults shows that drinking 250 mL of a specific mangosteen juice product (Lord Duke Biotechnology Corporation) containing mangosteen, pomegranate, acerola, white grape, strawberry, passion fruit, and tamarind, 1 hour prior to physical activity, does not improve time to exhaustion when compared to the juice product without mangosteen (92805).
• Muscle strength. Oral mangosteen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: One small clinical study in young, resistance-trained males shows that taking a combination product (CinDura, Laila Nutraceuticals) containing mangosteen fruit rind extract and Indian cassia leaf extract 400 mg twice daily for 42 days increases muscle strength and endurance when compared with placebo. Single bench and leg presses improved by approximately 23.5 kg and 29.3 kg, respectively, compared with 3.4 kg and 5.2 kg, respectively, in those taking placebo. Also, the number of leg extension repetitions increased by 6.5, compared to an increase of 2 with placebo (101079). It is not clear if these benefits are due to mangosteen, Indian cassia, or the combination.
• Obesity. Oral mangosteen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in healthy adults who were overweight shows that taking a specific combination product containing a mixture of mangosteen and Sphaeranthus indicus (Meratrim, Laila Nutraceuticals) 400 mg twice daily for 16 weeks results in weight loss of 6.7%, compared with weight loss of 1.4% with placebo (97876). In adults with obesity, taking the same dose of this product for 8 weeks results in an additional reduction in body weight of 4.6% when compared with placebo (97878,97879). This product also seems to improve body mass index (BMI), waist and hip measurements, and blood lipids in some patients (97876,97878,97879). It is not clear if these benefits are due to mangosteen, Sphaeranthus indicus, or the combination.
• Osteoarthritis. Topical mangosteen has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A large, single-blind clinical study in adults with knee osteoarthritis causing moderate pain shows that applying a specific cream (TMP-4) containing extracts of mangosteen peel, sesame seed, soybean, and gotu kola leaf four times daily for 4 weeks provides similar improvement in pain scores when compared with diclofenac 1% gel. Topical TMP-4 cream also seems to improve knee stiffness, stair climbing, and mobility similarly to diclofenac gel. However, patient impression of overall improvement was higher with diclofenac (110128). The validity of this study is limited by inadequate blinding.
• Schizophrenia. It is unclear if oral mangosteen is beneficial in schizophrenia. Details: A clinical study in adults with schizophrenia or schizoaffective disorder shows that taking mangosteen pericarp 1000 mg daily for 24 weeks does not improve total symptom severity when compared with placebo (106787). A secondary analysis of cognitive outcomes also did not demonstrate any differences (106790). More evidence is needed to rate mangosteen for these uses.

• HIV/AIDS. Although there has been interest in using oral noni for HIV/AIDS, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Hypertension. It is unclear if oral noni is beneficial in patients with hypertension. Details: Preliminary clinical research shows that drinking 4 ounces of a specific noni juice (Tahitian Noni Juice) daily for one month reduces blood pressure by approximately 8% when compared with baseline in individuals with hypertension (65231). The validity of this finding is limited by the lack of a comparator group.
• Insomnia. Although there has been interest in using oral noni for insomnia, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Leishmania lesions. It is unclear if topical noni is beneficial for improving the severity of leishmania lesions. Details: Preliminary clinical research shows that topical application of an ointment containing noni stem extract 1% three times daily for 6 weeks improves leishmania lesion scores when compared with baseline. A good to excellent response was reported in 80% of patients (65174). However, the validity of this finding is limited by the lack of a comparator group.
• Leprosy. Although there has been interest in using topical noni for leprosy, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Liver disease. Although there has been interest in using oral noni for liver disease, there is insufficient reliable information about the clinical effects of noni for this purpose. Additionally, there is some concern that noni might cause hepatotoxicity in some patients.
• Malaria. Although there has been interest in using oral noni for malaria, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Migraine headache. Although there has been interest in using oral noni for migraine headache, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Osteoarthritis. It is unclear if oral noni is beneficial in patients with osteoarthritis. Details: Preliminary clinical research in patients with knee or hip osteoarthritis shows that drinking 3 ounces of a specific noni juice (Tahitian Noni Juice) daily for 90 days can reduce the need for analgesic medications and improve quality of life parameters, including mobility, joint function, social activity, tension level, mood, and the ability to conduct activities of daily living when compared with baseline (65206). However, the validity of this study is limited by the lack of a comparator group.
• Parturition. Although there has been interest in using oral noni for parturition, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Postoperative nausea and vomiting (PONV). It is unclear if oral noni is beneficial in patients with PONV. Details: Preliminary clinical research shows that taking noni fruit extract 600 mg orally one hour prior to surgery reduces postoperative nausea, but not vomiting, in the first 6 hours after surgery by 40% when compared with placebo. However, taking noni fruit extract did not reduce PONV in the first 6-24 hours after the surgery. Taking noni fruit extract 150-300 mg also did not reduce PONV when compared with placebo (17169).
• Premenstrual syndrome (PMS). Although there has been interest in using oral noni for PMS, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Rheumatoid arthritis (RA). Although there has been interest in using oral and topical noni for RA, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Stroke. Although there has been interest in using oral noni for stroke, there is insufficient reliable information about the clinical effects of noni for this purpose.
• Urinary tract infections (UTIs). Oral noni has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Some observational research in females with recurrent UTIs has found that taking antibiotics with a combination of noni fruit extract 200 mg, d-mannose 500 mg, and N-acetylcysteine 100 mg orally twice daily for 2 months, then daily for 4 months, may be associated with a lower incidence of recurrent UTI when compared with antibiotics alone. Of patients without a UTI in the first 2 months, 100% of those taking the combination product remained UTI free at 6 months whereas only 6% of those taking antibiotics alone remained UTI free. This combination also seems to improve symptoms of urgency, frequency, and incontinence (97360). It is not clear if these effects are due to noni, other ingredients, or the combination.
• Wound healing. Although there has been interest in using topical noni for wound healing, there is insufficient reliable information about the clinical effects of noni for this purpose. More evidence is needed to rate noni for these uses.

• Hypertension. Oral pomegranate juice seems to modestly reduce blood pressure. Details: Most clinical research evaluating pomegranate juice for reducing systolic blood pressure (SBP) and diastolic blood pressure (DBP) shows modest benefits (8310,13023,13691,69372,69373,69374). A meta-analysis of results from eight clinical studies including 574 patients shows that pomegranate juice reduces SBP by about 5 mmHg, but does not affect DBP, when compared with placebo. Doses of pomegranate juice ranged from 43-330 mL daily for 2 weeks to 18 months. Changes in SBP and DBP were not related to the dose or duration of pomegranate juice consumption (96247).

POSSIBLY INEFFECTIVE

• Diabetes. Most oral pomegranate products do not seem to be beneficial for diabetes. It is unclear if pomegranate seed powder is beneficial. Details: A meta-analysis of clinical research shows that taking pomegranate has no effect on glycated hemoglobin (HbA1c) or plasma levels of insulin, lipids, or fasting glucose when compared with placebo in patients with type 2 diabetes. Various formulations, including juice, fruit extract, peel extract, and seed oil, were used in these studies (105265). However, a more recent clinical trial shows that drinking a beverage twice daily for 8 weeks, made by soaking a 'tea bag' containing pomegranate seed powder 5 grams in hot water for 10 minutes, modestly reduces levels of fasting blood glucose, HbA1c, total cholesterol, and triglycerides when compared with placebo. Fasting blood glucose levels were reduced by approximately 4%, compared with a 6% increase in the placebo group (105270).
• Hyperlipidemia. Oral pomegranate does not seem to be beneficial for hyperlipidemia. Details: Most clinical research shows that taking pomegranate does not increase high-density lipoprotein (HDL) cholesterol levels or reduce total cholesterol, low-density lipoprotein (LDL) cholesterol, or triglyceride levels when compared with placebo (13022,13023,13690,69142,69168,69276). A meta-analysis of results from 12 clinical studies including 545 patients with or without hyperlipidemia shows that taking pomegranate daily for at least 10 days and up to 1 year does not improve blood lipid levels when compared with placebo. Pomegranate formulations evaluated in these studies include juice, seed oil, whole fruit, extract, and vinegar beverage; no specific form or dose of pomegranate was associated with improvements in cholesterol or triglyceride levels (96248). One preliminary clinical study has evaluated pomegranate juice in combination with other fruits. Results from the study show that taking a specific pomegranate-containing combination product (Radical Fruits, Garden of Life) 900 mg orally three times daily before meals reduces total and LDL cholesterol and increases HDL cholesterol in males with hypercholesterolemia (69170). However, it is unclear if these benefits are due to pomegranate, other ingredients, or the combination.

• Atherosclerosis. It is unclear if oral pomegranate juice is beneficial for preventing atherosclerosis. Details: Preliminary clinical research shows that drinking pomegranate juice 50 mL daily reduces intima-media thickness of the carotid artery by up to 35% after one year when compared to baseline in patients with atherosclerosis and carotid artery stenosis (13023).
• Athletic performance. It is unclear if oral pomegranate extract is beneficial for athletic performance. Details: Preliminary clinical research in trained male cyclists shows that taking pomegranate extract (POM Wonderful LLC) 15 mg/kg daily for 8 days moderately reduces the amount of oxygen needed to perform submaximal exercise when compared with placebo. However, pomegranate extract does not improve performance in a timed trial (99100). Other preliminary clinical research in regionally competitive male cyclists shows that taking pomegranate extract (Pomanox P30, Euromed S.A.) 750 mg daily for 15 days increases the time to exhaustion by 94 seconds after a prolonged submaximal effort, as well as the time to reach the anaerobic threshold by about 55 seconds, when compared with placebo. There was no effect on the restoration of force or on oxygen consumption (101881).
• Chronic obstructive pulmonary disease (COPD). It is unclear if oral pomegranate juice is beneficial for COPD. Details: A small clinical trial shows that drinking pomegranate juice 400 mL daily for 5 weeks does not improve symptoms or respiratory function in patients with COPD when compared with placebo (13692).
• Coronary heart disease (CHD). It is unclear if oral pomegranate juice is beneficial for patients with CHD. Details: Some preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 240 mL daily for 3 months decreases stress-induced myocardial ischemia in patients with CHD. The average improvement in myocardial perfusion was about 17% with pomegranate juice, compared with an 18% worsening of myocardial perfusion in patients taking placebo (13691). However, other preliminary clinical research in patients with moderate CHD risk shows that drinking the same pomegranate juice product 240 mL daily for 18 months does not improve carotid intima-media thickness when compared to control (17329). It is not known if drinking pomegranate juice can prevent or reduce the risk of a myocardial infarction or other cardiovascular outcomes.
• Dental plaque. It is unclear if rinsing the mouth with pomegranate extract is beneficial for reducing dental plaque. Details: Preliminary clinical research shows that rinsing with pomegranate extract mouthwash for one minute once or twice daily reduces dental plaque in patients with or without fixed orthodontic appliances. The antiplaque activity of pomegranate extract is similar to that of chlorhexidine (69171,69316).
• Erectile dysfunction (ED). It is unclear if oral pomegranate juice is beneficial for ED. Details: In patients with mild-to-moderate ED, preliminary clinical research shows that drinking pomegranate juice daily for 4 weeks does not improve symptoms of ED when compared with placebo (69175).
• Exercise-induced muscle soreness. It is unclear if oral pomegranate juice is beneficial for reducing exercise-induced muscle soreness. Details: Preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 250 mL twice daily for 15 days reduces post-exercise muscle soreness in elbow flexor, but not knee extensor, muscles in resistance-rained males when compared with placebo (69355). However, in non-resistance trained males, drinking the same pomegranate juice 250 mL twice daily for 9 days does not reduce exercise-induced muscle damage or delayed onset soreness of elbow flexor muscles when compared with placebo (101880).
• HIV/AIDS. Although there has been interest in using oral pomegranate for HIV/AIDS, there is insufficient reliable information about the clinical effects of pomegranate for this condition.
• Influenza. Although there has been interest in using oral pomegranate for influenza prevention, there is insufficient reliable information about the clinical effects of pomegranate for this purpose.
• Intrauterine growth restriction (IUGR). It is unclear if oral pomegranate juice is beneficial for preventing brain injury in IUGR neonates. Details: In patients with an IUGR pregnancy, clinical research shows that drinking pomegranate juice 8 ounces daily from 24-34 weeks' gestation until delivery reduces the risk of an MRI-diagnosed gray matter brain injury in the infant by approximately 28%. There was no effect on brain volume or white matter injury (105267).
• Kidney failure. It is unclear if oral pomegranate juice is beneficial for patients on hemodialysis; the available research is conflicting. Details: Some preliminary clinical research shows that taking pomegranate juice (Nutrafood) 100 mL during the first dialysis treatment hour three times weekly for one year reduces antihypertensive medication requirements and the rate of second hospitalization due to infection when compared with placebo. Consuming pomegranate juice also increases high-density lipoprotein (HDL) cholesterol in patients with baseline levels of 40 mg/dL or less and reduces triglycerides in patients with baseline levels of at least 200 mg/dL (91698,91699). Preliminary clinical research also shows that taking pomegranate juice 100 mL immediately after dialysis three times weekly for 8 weeks reduces triglycerides by approximately 20%, as well as systolic and diastolic blood pressure by 5% and 7%, respectively, when compared with baseline. HDL cholesterol was also increased by approximately 23%. These changes were significant when compared with placebo (101882). However, pomegranate juice did not affect total cholesterol, low-density lipoprotein (LDL) cholesterol, liver enzymes, or incidence of cardiovascular events when compared with placebo (91698,91699,101882). Other preliminary clinical research shows that drinking pomegranate juice (POM Wonderful Pomegranate Juice, POM Wonderful LLC) 100 mL or taking pomegranate juice extract tablets (POM Wonderful LLC) 1050 mg daily prior to each dialysis session for 4 weeks does not improve blood pressure, lipids, or markers of inflammation and oxidative stress when compared to baseline in patients receiving maintenance hemodialysis (91697). Although the reason for these conflicting findings is not clear, it may have to do with the timing of consumption. The evidence suggests that offering pomegranate during dialysis or after completion of dialysis might be more effective than prior to dialysis.
• Menopausal symptoms. It is unclear if oral pomegranate seed oil or pomegranate extract is beneficial for menopausal symptoms. Details: Preliminary clinical research shows that taking a specific pomegranate seed oil (Delima, Pekana Naturheilmittel GmbH) 30 mg orally twice daily for 12 weeks does not reduce the frequency of hot flashes when compared with placebo in postmenopausal adults experiencing at least 5 hot flashes per day. However, pomegranate seed oil might improve sleep in some patients with sleep disturbances attributed to menopause (91685). A clinical study in healthy, perimenopausal and menopausal adults with untreated menopausal symptoms shows that taking pomegranate extract 3 mL three times daily for 4 weeks reduces symptoms, including hot flashes and vertigo, and improves physical and mental quality of life when compared with placebo. Additionally, these improvements were sustained 3 weeks after discontinuing treatment (108484). The validity of this study is limited by the short duration of treatment.
• Metabolic syndrome. It is unclear if oral pomegranate juice is beneficial for metabolic syndrome. Details: Preliminary clinical research shows that drinking pomegranate juice 240 mL daily for one month improves endothelial dysfunction in adolescents with metabolic syndrome when compared with drinking grape juice 240 mL daily (53174,69362).
• Muscle strength. It is unclear if oral pomegranate juice is beneficial for increasing muscle strength. Details: Preliminary clinical research shows that taking a specific pomegranate extract (POMx, POM Wonderful LLC) 480 mL twice daily modestly improves recovery of strength 2-3 days after eccentric exercise but does not reduce muscle soreness after exercise when compared with placebo (69261).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral pomegranate seed oil or pomegranate extract improves anthropometric measures in adults with NAFLD. Details: A small clinical study in overweight and obese adults with NAFLD shows that taking a dried pomegranate extract, standardized to contain 90 mg of ellagic acid, twice daily for 12 weeks reduces body mass index and body weight when compared with placebo. A 5 kg weight reduction occurred in the pomegranate group, compared to a small increase in weight in the placebo group. Pomegranate also improved diastolic blood pressure, as well as lipid and glycemic parameters; however, the patients included in this study had normal baseline parameters, limiting the validity of this finding (108481). Pomegranate has also been evaluated in combination with other ingredients. One small clinical crossover study in obese females with NAFLD shows that taking a specific combination product (Xanthigen, Polinat) containing pomegranate seed oil 300 mg and brown marine algae 300 mg (standardized to fucoxanthin 2.4 mg) modestly reduces body weight and liver fat content when compared with placebo (69257).
• Obesity. It is unclear if oral pomegranate is beneficial for obesity. Most evidence suggests that it is not beneficial, although some studies have yielded conflicting findings. Details: A meta-analysis of 513 participants shows that taking pomegranate extract, juice, or concentrate for 2-26 weeks does not reduce body weight, body mass index, waist circumference, or body fat percentage when compared with placebo or other control (101883). However, most of these studies were not designed to investigate weight as the primary outcome, and some preliminary clinical research in overweight or obese individuals suggests that some pomegranate products might have some benefit. Drinking pomegranate juice 120 mL daily for one month helps these individuals maintain weight when compared with placebo, although it does not appear to improve glucose, insulin secretion, or insulin sensitivity (91693).
• Oropharyngeal candidiasis. It is unclear if topical pomegranate peel extract is beneficial for oropharyngeal candidiasis. Details: Preliminary clinical research in patients with candidiasis associated with denture stomatitis shows that applying a gel containing the extract of pomegranate fruit peel to the gums three times daily for 15 days seems to be as effective as miconazole gel for improving symptoms of candidiasis (13689).
• Polycystic ovary syndrome (PCOS). It is unclear if oral pomegranate juice is beneficial for PCOS. Details: In patients with PCOS, preliminary clinical research shows that taking pomegranate juice 45 mL daily for 8 weeks reduces systolic and diastolic blood pressures by 10 and 4 mmHg, respectively, when compared with a control group not taking pomegranate juice. Triglyceride and high-density lipoprotein (HDL) cholesterol levels were also modestly improved. However, there was no effect on glycemic measures, and low-density lipoprotein (LDL) cholesterol levels increased by 6 mg/dL (105266). Another clinical trial in patients with PCOS shows that taking synbiotic pomegranate juice containing inulin and lactobacillus as 2 liters weekly for 8 weeks improves insulin sensitivity, body mass index, waist circumference, and testosterone levels when compared with baseline or a control juice. However, patients consuming a drink containing only the synbiotic ingredients experienced the same improvements, whereas patients consuming only regular pomegranate juice experienced no benefits, suggesting that pomegranate was not responsible for these changes (101884).
• Prostate cancer. It is unclear if oral pomegranate extract or juice is beneficial for prostate cancer. Details: Preliminary clinical research shows that pomegranate might slow prostate cancer progression in some patients after surgery or radiation for prostate cancer. The length of time to doubling of prostate specific antigen (PSA) was longer in those who took a specific pomegranate extract (POMx, POM Wonderful LLC) 1-3 grams daily, as well as those who drank 8 ounces of pomegranate juice daily, for up to 24 months (14137,14388,91695). However, the results from a large well-designed study do not support these findings. This study shows that taking 8 ounces of a pomegranate liquid extract does not increase the length of time to doubling of PSA (105271). In patients with favorable-risk localized prostate cancer, a small clinical trial also shows that taking pomegranate fruit extract (POMx, POM Wonderful) 1000 mg daily for 12 months does not affect the length of time to doubling of PSA, although there were some changes in tumor markers of DNA damage (105269). Pomegranate has also been evaluated in combination with other ingredients. Preliminary clinical research in patients with localized prostate cancer shows that taking a combination supplement containing pomegranate powder 100 mg, broccoli powder 100 mg, turmeric powder 100 mg, and green tea extract 20 mg daily for 6 months slows the increase in PSA levels when compared with placebo (89730). It is not clear if this effect is due to pomegranate, the other ingredients, or the combination.
• Rheumatoid arthritis (RA). It is unclear if oral pomegranate extract is beneficial for RA. Details: Preliminary clinical research shows that taking a specific pomegranate extract (POMx, POM Wonderful LLC) 5 mL twice daily for 12 weeks decreases disease activity and reduces tender joint count by 62% when compared to baseline in patients with RA (91686). The validity of these findings is limited by the lack of a control group.
• Rhinosinusitis. It is unclear if intranasal pomegranate extract is beneficial for chronic rhinosinusitis. Details: A clinical study in adults with chronic rhinosinusitis or rhinitis persisting longer than 12 weeks, with or without the presence of nasal polyps, shows that using a nasal spray containing pomegranate extract in an unknown dose twice daily for 30 days does not improve objective or subjective nasal or sinus symptoms when compared with placebo nasal spray. In a subgroup of patients with chronic rhinitis, including allergic and nonallergic rhinitis, improvement in thick nasal discharge is also observed in those receiving the pomegranate nasal spray; however, the study does not report outcomes for each subtype of rhinitis (108480).
• Stroke. Although there has been interest in using oral pomegranate for stroke recovery, there is insufficient reliable information about the clinical effects of pomegranate for this purpose.
• Sunburn. It is unclear if oral pomegranate extract is beneficial for sunburn prevention. Details: A small clinical study shows that taking pomegranate extract standardized to contain ellagic acid 100-200 mg daily for 4 weeks does not reduce skin pigmentation caused by UV light exposure when compared with placebo (69172). However, this study was not adequately powered to detect a difference between treatments.
• Trichomoniasis. It is unclear if oral pomegranate extract is beneficial for trichomoniasis. Details: A very small clinical study in patients with vaginal Trichomoniasis suggests that taking pomegranate extract might help to eradicate Trichomonas vaginalis infection (69286). The validity of this finding is limited by the small study size, unclear reporting, and lack of a control group. More evidence is needed to rate pomegranate for these uses.

POSSIBLY SAFE ...when used orally and appropriately. Noni juice has been used in doses of up to 200 mL daily with apparent safely in small clinical studies for up to 3 months (11944,17169,65173). However, there have been several case reports of increased liver enzymes and hepatotoxicity in people taking some noni products (13107,14341,14468,17170,17171,17172). In three reports, hepatotoxicity was linked to a specific brand of noni juice (Tahitian Noni Juice, Tahitian Noni International) (14341,17171). It is unclear if potential contaminants or hypersensitivity reactions may be the cause of these events. More evidence is needed to determine if noni increases the risk for hepatotoxicity. There is insufficient reliable information available about the safety of noni fruit extract when used orally or the safety of noni when used topically.

PREGNANCY AND LACTATION:
While animal research is conflicting on the teratogenic effects of noni (65205,65206), there is insufficient reliable information available about the safety of noni in humans; avoid using.

LIKELY SAFE ...when pomegranate fruit or fruit juice is used orally and appropriately. Pomegranate juice has been safely used in studies lasting up to 3 years (4912,8310,13022,13023,13690,14137,14388,17329,91693).

POSSIBLY SAFE ...when pomegranate extract is taken orally and appropriately. A specific pomegranate ellagitannin-enriched polyphenol extract (POMx, POM Wonderful) 1-3 grams daily has been safely used for up to 18 months (17729,69261,91686,91695,91697,99100,105269). ...when pomegranate seed oil is used orally and appropriately. Pomegranate seed oil 60 mg daily has been used with apparent safety for up to 12 weeks (91685). ...when a hot water extract of pomegranate seed powder is used orally and appropriately. Pomegranate seed powder 5 grams daily has been used with apparent safety for up to 8 weeks (105270). ...when pomegranate extract is used topically on oral mucosa (13689).

POSSIBLY UNSAFE ...when the pomegranate root, stem, and peel are used orally in large amounts. Bark of the pomegranate root and stem contains the piperidine alkaloids pelletierine, pseudopelletierine, isopelletierine, and methyl isopelletierine. These alkaloids have muscle relaxant properties that have been associated with paralysis and death in animals (13687,13694,13695). Dried pomegranate peel may contain aflatoxin, which is a potent hepatocarcinogen and toxin (92018).

PREGNANCY AND LACTATION: POSSIBLY SAFE
when the fruit or fruit juice is consumed orally and appropriately (13686,105267). There is insufficient reliable information available regarding the safety of using other forms of pomegranate or other parts of the plant during pregnancy or lactation; avoid using.

ANTIDIABETES DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.  Details Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects (7126,92118,94667). However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia (92117).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.  Details Animal and in vitro research suggest that goji root bark has hypotensive effects (7126,94667). However, goji fruit juice does not appear to reduce systolic or diastolic blood pressure in humans (17082).

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.  Details In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes (105486). Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate (7158,105462). Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.  Details In vitro research shows that goji berry juice inhibits CYP2D6 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.  Details In vitro research shows that goji berry juice inhibits CYP3A4 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.

FLECAINIDE (Tambocor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goji berry might increase the levels and clinical effects of flecainide.  Details In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide (105462).

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Goji can increase the effects of warfarin and possibly increase the risk of bleeding.  Details There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine (7158,16529,23896,105462,105487). Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9) (7158).

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, concomitant use of mangosteen with anticoagulant or antiplatelet drugs may increase the risk of bleeding.  Details In vitro and animal research shows that gamma-mangostin, a constituent of mangosteen, is a potent and competitive antagonist of the serotonin 2A (5-HT2A) receptor. Antagonism of the 5-HT2A receptor is believed to reduce platelet aggregation (12017,61685,61686).

ACE INHIBITORS (ACEIs) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, combining noni and ACE inhibitors might increase the risk of hyperkalemia.  Details Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice (1298). This may increase the risk for hyperkalemia when used in conjunction with ACE inhibitors, which can also increase potassium levels.

ANGIOTENSIN RECEPTOR BLOCKERS (ARBs) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, combining noni and ARBs might increase the risk of hyperkalemia.  Details Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice (1298). This may increase the risk for hyperkalemia when used in conjunction with ARBs, which can also increase potassium levels.

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, noni may increase the risk of hypotension when used in combination with antihypertensive drugs.  Details Preliminary clinical research suggests that drinking noni juice can reduce blood pressure in individuals with hypertension (65231).

HEPATOTOXIC DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking noni with hepatotoxic drugs might increase the risk of liver damage.  Details There is concern that noni might cause hepatotoxicity in some patients (13107,14341,14468). Advise patients against combining noni with potentially hepatotoxic drugs.

PHENYTOIN (Dilantin) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking noni fruit juice concomitantly with phenytoin may lower phenytoin levels and increase the risk of seizures.  Details In one case report, an adult taking phenytoin for partial seizures experienced low serum phenytoin levels while taking noni juice 90-200 mL daily. Serum phenytoin levels increased after decreasing noni juice consumption; similarly, serum phenytoin levels decreased after increasing noni juice consumption. Some researchers believe noni juice may induce cytochrome P450 2C9 enzymes, which would decrease phenytoin levels, but this has not been well studied. Patients may need additional monitoring when starting or stopping noni juice supplementation (106057).

POTASSIUM-SPARING DIURETICS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, combing noni and a potassium-sparing diuretic might increase the risk of hyperkalemia.  Details Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice (1298). This may increase the risk for hyperkalemia when used in conjunction with potassium-sparing diuretics, which can also increase potassium levels.

RANITIDINE (Zantac) Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = B Taking noni fruit with ranitidine might increase the levels and clinical effects of ranitidine.  Details Clinical evidence shows that taking an aqueous extract of noni fruit 30 minutes prior to taking a single oral dose of ranitidine can increase the rate of absorption and plasma concentration of ranitidine (23387).

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking noni juice concomitantly with warfarin might decrease the effectiveness of warfarin.  Details In one case, a 41-year-old patient stabilized on warfarin had a decreased international normalized ratio (INR) following consumption of a specific commercial noni juice product (Noni juice 4 Everything). While the patient was still taking noni juice, an increase in warfarin dose did not produce an increase in INR (14434). However, it should be noted that this particular product contained extracts and derivatives from more than 115 components, many of which contained vitamin K. Furthermore, vitamin K was listed as a separate ingredient of the product, suggesting that the product was possibly fortified with vitamin K. It has not been verified that noni fruit alone contains a significant amount of vitamin K or interacts with warfarin.

ACE INHIBITORS (ACEIs) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking pomegranate with ACEIs might increase the risk of adverse effects.  Details Pomegranate juice is thought to have ACE inhibitor-like effects (8310).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, taking pomegranate with antihypertensive drugs might increase the risk of hypotension.  Details Consuming pomegranate juice can modestly lower blood pressure (8310,13023,69373,69374).

CARBAMAZEPINE (Tegretol) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, taking pomegranate with carbamazepine might increase the risk of adverse effects, although research suggests this interaction is unlikely to be clinically significant.  Details Animal research shows that pomegranate juice may inhibit cytochrome P450 3A4 (CYP3A4) metabolism of carbamazepine and increase levels of carbamazepine by 1.5 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP3A4, but might not inhibit hepatic CYP3A4 (13188). However, some human research suggests that pomegranate does not significantly inhibit CYP3A4 drug metabolism in humans (16711,16712,17326).

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = B Theoretically, pomegranate might increase levels of drugs metabolized by CYP2C9.  Details Some animal and in vitro research shows that pomegranate juice inhibits intestinal, but not hepatic, CYP2C9 isoenzyme activity (17327). However, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans (91694).

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, pomegranate might increase levels of drugs metabolized by CYP2D6.  Details In vitro, pomegranate juice inhibits CYP2D6 (13703). However, the clinical significance of this potential interaction in humans is not known.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = B Theoretically, pomegranate might increase levels of drugs metabolized by CYP3A4, but most research suggests this interaction is unlikely to be clinically significant.  Details Pomegranate contains several polyphenols that have individually been shown to inhibit CYP3A4. However, there is contradictory evidence about the effect of whole pomegranate juice on CYP3A4 activity. In vitro, pomegranate juice significantly inhibits the CYP3A4 enzyme, with comparable inhibition to grapefruit juice (13188,16711,17326). In an animal model, pomegranate juice inhibits CYP3A4 metabolism of carbamazepine and increases levels of carbamazepine by 1.5 times (13188); however, in human volunteers, drinking a single glass of pomegranate juice 240 mL or taking 200 mL daily for 2 weeks does not significantly affect levels of the CYP3A4 substrate midazolam after oral or intravenous administration (16711,17730). Another study in healthy volunteers shows that consuming pomegranate juice 300 mL three times daily for three days also does not significantly affect levels of simvastatin, a CYP3A4 substrate (16712,91696) This suggests that pomegranate is unlikely to significantly affect levels of CYP3A4 substrates in humans (17326).

ROSUVASTATIN (Crestor) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking pomegranate with rosuvastatin might increase the risk of adverse effects.  Details In one case, a patient taking rosuvastatin 5 mg every other day in combination with ezetimibe 10 mg daily developed rhabdomyolysis after drinking pomegranate juice 200 mL twice weekly for 3 weeks. This patient had a history of elevated creatine kinase levels while not receiving any statin treatment. This suggests a possible underlying myopathy and predisposition to rhabdomyolysis (14465).

TOLBUTAMIDE (Orinase) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, pomegranate might increase levels of tolbutamide, although research suggests this interaction is unlikely to be clinically significant.  Details Animal research shows that pomegranate juice inhibits the cytochrome P450 2C9 (CYP2C9) metabolism of tolbutamide. Pomegranate juice increased tolbutamide levels by 1.2 times without prolonging the elimination half-life. This suggests that pomegranate juice inhibits intestinal CYP2C9, but might not inhibit hepatic CYP2C9 (17327). Despite this evidence, clinical research shows that neither pomegranate juice nor pomegranate extract have a significant effect on CYP2C9 activity in humans (91694). This interaction does not appear to be clinically significant in humans.

WARFARIN (Coumadin) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, pomegranate might increase warfarin levels and increase the risk of bleeding. Also, discontinuing regular consumption of pomegranate juice might decrease warfarin levels.  Details In one case report, a patient had a stable, therapeutic bleeding time, as measured by international normalized ratio (INR), while taking warfarin in combination with pomegranate juice 2-3 times per week. The patient became subtherapeutic within about 10 days after discontinuing pomegranate juice, which required a warfarin dose increase (17328). In another case report, a patient with a stable INR for over one year presented with an INR of 14. The patient noted no changes to medications or diet but did report consuming around 3 liters of pomegranate juice over the previous week. The patient's INR stabilized upon moderation of pomegranate juice consumption (24273). The mechanism of this potential interaction is unclear.

General ...Orally, goji fruit seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions including anaphylaxis.

Dermatologic ...A case of photosensitivity secondary to consumption of goji berries has been reported. The patient presented with a pruriginous eruption that had lasted for 2 weeks. The patient had been taking goji berries for 5 months and cat's claw for 3 months. Upon testing, it was revealed that the patient tested positive to goji berries in a photoprovocation test, but not to cat's claw (40263).

Hepatic ...Orally, consumption of goji berries has been associated with a single case report of autoimmune hepatitis (52541). A case of acute hepatitis has also been reported in a female who consumed 2 ounces of a specific combination product (Euforia, Nuverus International) containing goji berry, pomegranate, curcumin, green tea, noni, acai berry, aloe vera, blueberry, resveratrol, mangosteen, and black seed, daily for one month. It is unclear whether the liver injury was caused by goji berry, other ingredients, or the combination (90125).

Immunologic ...Several cases of allergic reactions secondary to consumption of goji berries have been reported. Symptoms included facial angioedema with dyspnea, pharyngeal itching, itching in the mouth, ears, and axilla, labial angioedema, and perioral skin rash (92116). Anaphylaxis has also been reported (52538).

General ...Orally, mangosteen is generally well tolerated. Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Lactic acidosis.

Dermatologic ...Orally, mangosteen extract up to 560 mg daily has been reported to cause skin rash. It is not known if this side effect was related to mangosteen (97877).

Gastrointestinal ...Orally, mangosteen extract up to 560 mg daily has been reported to cause constipation, abnormal stool, abdominal discomfort, abdominal bloating, salivation, nausea and vomiting, and diarrhea. It is not known if these side effects were related to mangosteen (97877).

Neurologic/CNS ...Orally, mangosteen extract up to 560 mg daily has been reported to cause mild tiredness, headache, dizziness, and malaise. It is not known if these side effects were related to mangosteen (97877).

Pulmonary/Respiratory ...Orally, mangosteen extract up to 560 mg daily has been reported to cause dry throat, flu-like symptoms, cough, and nasal congestion. It is not known if these side effects were related to mangosteen (97877).

Renal ...Orally, mangosteen extract up to 560 mg daily has been reported to cause abnormal urination. It is not known if this side effect was related to mangosteen (97877). In one case report, a patient with chronic kidney disease and metabolic syndrome consumed mangosteen juice daily for 12 months and later presented with severe lactic acidosis. The juice was reported to contain 250 mg of mangosteen with 25 mg alpha-mangostin per ounce. Alpha-mangostin appears to inhibit mitochondrial function, disrupting the electron transport chain and adenosine triphosphate (ATP) production, causing accumulation of reactive oxygen species and inducing apoptosis. Researchers speculate that these effects might have led to lactic acidosis in this patient (16399).

Other ...Orally, mangosteen extract up to 560 mg daily has been reported to cause weight loss. It is not known if this side effect was related to mangosteen (97877).

General ...Orally and topically, noni seems to be generally well tolerated; however, high quality studies of adverse effects have not been conducted.
Most Common Adverse Effects:
Orally: Abdominal discomfort, nausea.
Serious Adverse Effects (Rare)::
Orally: Hepatotoxicity, including liver failure. However, studies have not conclusively identified whether noni, or contaminants in noni products, were responsible for this toxicity.

Gastrointestinal ...Orally, dehydrated noni fruit has been reported to cause nausea and abdominal discomfort (65173).

Hepatic ...Noni has been associated with several cases of hepatotoxicity in previously healthy patients ranging in age from 14 to 62 years (13107,14341,14468,17170,17171,17172). In two cases, the patients had used a tea or other herbal products containing noni (13107,17172); five had consumed noni juice, specifically Tahitian Noni Juice (Tahitian Noni International) (14341,16648,17171); and two cases involved energy drinks containing several herbal ingredients including noni (17170,90125). Symptoms of liver dysfunction and elevated liver function tests (LFTs) were seen between 2 weeks and 4 months after starting noni. The LFTs started to improve within 2 days of stopping noni and generally normalized within 1 month (13107,14468,17171). Biopsy findings included acute hepatitis, inflammation, hepatocyte necrosis, and hepatocellular cholestasis (14341,17170). One patient, who had a history of prior mild acetaminophen toxicity, had rapidly progressive liver failure after noni ingestion and required transplantation (14341).
Potential product contamination was not ruled out in these case reports. Some researchers theorize that anthraquinones contained in noni could potentially cause hepatotoxicity. Other products containing anthraquinones, such as senna, have been linked to cases of hepatotoxicity. However, analyses of a noni juice product associated with reports of liver damage (Tahitian Noni Juice, Tahitian Noni International) have not detected anthraquinone content (14444). Another analysis of noni fruit puree from which the seeds and skin had been removed had no detectable anthraquinones (92201). However, products containing seed or leaf material had detectable amounts of anthraquinones (92201). The part of the noni plant used might affect hepatotoxicity risk. More evidence is needed to determine if noni causes hepatotoxicity.

General ...Orally, pomegranate fruit juice is generally well tolerated. Pomegranate fruit extract and seed oil seem to be well tolerated. Pomegranate root, stem, and peel should not be used orally in large amounts. Topically, pomegranate fruit extract seems to be well tolerated.
Most Common Adverse Effects:
Oral: Diarrhea, flatulence.

Cardiovascular ...In one clinical trial, 2% of patients experienced hyperlipidemia and hypertension after consumption of pomegranate juice (69175). However, most clinical research shows that pomegranate does not increase cholesterol or blood pressure and may actually improve these parameters in some patients (8310,13022,13023,69168,69373,69374).

Dermatologic ...Topically, pomegranate may cause urticaria (hives) in some patients (8445).

Gastrointestinal ...Orally, pomegranate may cause mild gastrointestinal adverse effects. In one clinical study, drinking pomegranate juice 8 ounces daily caused diarrhea and flatulence in 2% of patients (69175). In another clinical study, taking pomegranate extract (POMx, POM Wonderful LLC) 3000 mg daily caused diarrhea in 10% of patients. This dose of pomegranate extract also caused nausea, abdominal pain, constipation, gastrointestinal upset, and vomiting in a small number of patients (91695).

Immunologic ...Orally, pomegranate fruit or seeds may cause allergic reactions. These allergic reactions occur more commonly in people who are allergic to other plants (7674). In rare cases, pomegranate fruit can cause angioedema. Angioedema seems to occur without warning and in people who have eaten pomegranate for many years. Patients should be told to stop eating pomegranate if swelling of the tongue or face develops (7673). In one report, a patient experienced pomegranate-dependent, exercise-induced anaphylaxis. The patient developed widespread urticaria (hives) and lip edema after eating pomegranate seeds and then exercising (17331). In another report, an atopic patient experienced an allergic reaction to pomegranate fruit. Symptoms included urticaria (hives), facial angioedema, and hypotension (91692).
Topically, pomegranate may cause contact hypersensitivity characterized by urticaria (hives), angioedema, rhinorrhea, red itchy eyes, and dyspnea arising within a few minutes of exposure (8445).

Pulmonary/Respiratory ...Orally, pomegranate juice may cause nasal congestion, but this event is rare. In one clinical study, pomegranate juice was associated with nasal congestion in 2% of patients (69175). There is also one case report of a 7-year-old asthmatic child who developed bronchospasm moments after ingesting several pomegranate seeds (69149).
