• Diarrhea. Low-quality evidence shows that oral cooked green bananas might be helpful for the management of acute and persistent diarrhea due to various causes in children. Details: Many clinical studies in children aged 5 months to 5 years with acute diarrhea of various etiologies shows that consuming cooked green bananas with or without rice for up to 14 days increases recovery rates by 30% to 266% when compared with control (93451,93462,93463,106469). Consuming cooked green bananas also reduced the need for rehydration therapy and the incidence of dehydration (93462,93463,106469). Clinical trials used cooked green bananas 50-100 grams per day in children aged 6-12 months, 100-200 grams per day in children aged 12-24 months, and 300 grams per day aged 24 months to 5 years (93451,93462,93463,106469). A moderate size, open label clinical study among children aged 6-35 months hospitalized with persistent diarrhea in Bangladesh shows that consuming a diet of green banana mixed with rice suji increases the number of children who recover within 5 days when compared with a full-strength rice suji diet but is equivalent to the standard treatment (control) of 75% strength rice suji diet (112150). Duration of hospital stay is also similar with green banana and 75% strength rice suji and shorter than with full strength rice suji. There is also less relapse at home among children who had been given the green banana rice suji diet in hospital compared with the 75%-strength rice suji. The validity of the study is limited by the lack of blinding. Clinical research also shows that bananas might be beneficial for diarrhea associated with enteral feeding in adults with critical illness. Adding banana flakes (Kanana Banana, Corpak Co) 1-3 tablespoons every 8 hours to the feeding tube seems to be as effective as routine medical treatment involving feeding rate adjustments and use of antidiarrheal agents for reducing symptoms and duration of diarrhea. After 7 days of treatment, 57% of patients in the banana group were free of diarrhea compared with only 24% of patients in the group receiving routine treatment (93453).

• Allergic rhinitis (hay fever). Although there has been interest in using oral banana flower for allergic rhinitis, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Athletic performance. It is unclear if oral banana is beneficial for athletic performance. Details: Preliminary clinical research in trained male cyclists shows that consuming 0.4 grams/kg carbohydrate orally from ripe bananas with water 10-20 minutes prior to a 75 km cycling time trial, and 0.15-0.2 grams/kg carbohydrate from bananas with water every 15 minutes during the trial, modestly improves cycling time and oxygen consumption when compared with water alone. This regimen is equally effective to the same dose of carbohydrate from a 6% carbohydrate beverage (Gatorade) (93459,93465). However, another study from the same group of researchers found conflicting results with the use of carbohydrates from banana for this purpose (100995). It is possible that the consumption of carbohydrates in general, not the use of bananas specifically, is beneficial for athletic performance. However, other preliminary clinical research in trained male runners shows that consuming a banana and drinking plain water does not improve the time to run 10 km on a treadmill when compared with plain water alone. No benefit was seen with the consumption of other carbohydrate drinks when compared with plain water; it is possible that the duration of exercise was too short to identify an improvement in performance (93457). Further research is needed to clarify the benefits of banana, if any, for athletic performance.
• Burns. It is unclear if topical banana leaf is beneficial in patients with burns. Details: Preliminary clinical research in adults and children with partial thickness burns shows that daily changes of a banana leaf dressing with povidone iodine reduces pain during dressing changes. Furthermore, wound healing is as effective as a boiled potato peel bandage with povidone iodine, with no increased need for skin grafting (93454). When compared with Vaseline gauze dressing for 8 days following skin graft treatment for burns in adults, banana leaf dressing increases speed of epithelization from 11.7 days to 8.7 days, and improves average pain, pain during dressing removal, and ease of dressing removal. By the 8th day, complete epithelization was present in 57% of the wounds dressed with banana leaves when compared with 0% of the wounds dressed with Vaseline gauze (93455).
• Cancer. Although there has been interest in using topical banana green fruit for cancer, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Constipation. It is unclear if oral green banana is beneficial in patients with constipation. Details: Preliminary clinical research in children with functional constipation shows that consuming cooked green bananas, 30 grams daily for 8 weeks, improves stool consistency and abdominal pain and reduces straining and pain during defecation when compared with baseline. Consuming cooked green bananas with a conventional laxative such as polyethylene glycol plus electrolytes or sodium picosulfate also appears to decrease the dose of laxative needed in these children when compared with baseline (100996). The validity of these findings is limited by the lack of a comparator group.
• Contraception. Although there has been interest in using oral banana root for contraception, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Cough. Although there has been interest in using oral banana flower for cough, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Depression. It is unclear if oral banana is beneficial in patients with depression. Details: A large cross-sectional study in the general Chinese adult population has found that moderate, but not high, banana consumption is associated with a lower likelihood of depressive symptoms in males. However, high banana consumption is associated with a higher likelihood of depressive symptoms in females (106471).
• Diabetes. It is unclear if oral banana starch is beneficial in patients with diabetes. Details: Two small clinical studies in adults with type 2 diabetes shows that taking banana starch 24-57.2 grams orally daily for 4-28 days does not improve serum glucose levels, glucose variability, glucose control scores, or insulin levels when compared with control starches (110619,93448).Other preliminary clinical research in obese patients with type 2 diabetes shows that taking banana starch 24 grams in 240 mL of water each day for 4 weeks reduces body weight when compared with a taking soymilk powder in water. However, banana starch did not improve lipid levels or body fat (93448). Other preliminary clinical research in patients with type 2 diabetes shows that taking desiccated banana 250 grams daily for 12 weeks does not improve lipid levels or glycemic response when compared to baseline (93452).
• Exercise-induced muscle soreness. It is unclear if oral banana is beneficial for exercise-induced muscle soreness. Details: Preliminary clinical research in trained cyclists shows that consuming 0.4 grams/kg of carbohydrates orally from mini-yellow bananas with water 20 minutes prior to a 75 km cycling time trial, and 0.2 grams/kg of carbohydrates from banana every 15 minutes during the trial, decreases muscle soreness ratings 1.5 hours after the time trial when compared with water alone. Consuming carbohydrates from Cavendish bananas in the same manner did not decrease delayed onset muscle soreness, although cyclists reported less muscle cramping with both types of bananas when compared with water (100995). It is unclear whether carbohydrates from banana are any more effective than other carbohydrate sources or whether these results are generalizable to other types of exercise.
• Gastroesophageal reflux disease (GERD). Although there has been interest in using oral banana fruit for GERD, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Hangover. Although there has been interest in using oral banana fruit for hangover, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Headache. Although there has been interest in using topical banana leaves for headache, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Hypercholesterolemia. It is unclear if oral banana is beneficial in patients with hypercholesterolemia. Details: Preliminary clinical research shows that taking desiccated banana 500 grams orally daily for 12 weeks reduces levels of total cholesterol by 7.5% when compared with baseline in patients with hypercholesterolemia. Taking 250 grams daily does not seem to reduce total cholesterol levels; however, high-density lipoprotein (HDL) cholesterol levels increase by 14.5% (93452). The validity of these findings is limited by the lack of a comparator group.
• Hypertension. Although there has been interest in using oral banana fruit for hypertension, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Hypokalemia. Although there has been interest in using oral banana fruit for hypokalemia, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Inflammatory bowel disease (IBD). Although there has been interest in using oral banana fruit for IBD, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Joint pain. Although there has been interest in using oral banana flower for joint pain, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Kidney stones (nephrolithiasis). Oral banana stem has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with calculi of at least 5 mm shows that taking a specific Ayurvedic product (Herbmed) containing banana stem 250 mg and Crateva nurvala 250 mg orally daily for 3 months moderately improves symptoms associated with urinary calculi and reduces the size of the calculi by 11% to 33% when compared with baseline (93460). It is not clear if this is due to banana stem, Crateva nurvala, or the combination. Also, the validity of this finding is limited by the lack of a comparator group.
• Menorrhagia. Although there has been interest in using oral banana fruit for menorrhagia, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Obesity. It is unclear if oral banana is beneficial in patients with obesity. Details: Preliminary clinical research in obese patients with type 2 diabetes shows that taking banana starch 24 grams in 240 mL of water orally each day for 4 weeks reduces body weight by 1 kg more when compared to a control group consuming soymilk powder in water (93448).
• Peptic ulcers. Although there has been interest in using oral banana fruit for peptic ulcers, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Shigellosis. It is unclear if oral green banana is beneficial in patients with shigellosis. Details: Clinical research in children 6-60 months of age who are being treated with antibiotics for shigellosis shows that eating cooked green banana 250 grams per liter of a rice-based diet for 5 days improves symptoms of diarrhea, including the presence of fecal mucus and blood, when compared with a rice-based diet alone. Adding banana to the diet decreased the number of daily stools by 70% in those consuming banana compared to 50% in children consuming the rice diet alone (93461).
• Skin grafts. Although there has been interest in using topical banana leaves for skin grafts, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Smoking cessation. Although there has been interest in using oral banana fruit for smoking cessation, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Stroke. Although there has been interest in using oral banana fruit for stroke, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Tuberculosis. Although there has been interest in using oral banana flower for tuberculosis, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Vaginitis. Although there has been interest in using oral banana root for vaginitis, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Vitamin A deficiency. Although there has been interest in using oral banana fruit for vitamin A deficiency, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Warts. Although there has been interest in using topical banana leaves or peels for warts, there is insufficient reliable information about the clinical effects of banana for this purpose.
• Wound healing. Although there has been interest in using topical banana leaves, peels, or green fruit for wound healing, there is insufficient reliable information about the clinical effects of banana for this purpose. More evidence is needed to rate banana for these uses.

POSSIBLY EFFECTIVE

• Constipation. Glucomannan is generally effective for treatment of constipation in adults, but the efficacy in children is less clear. Details: Clinical research in adults shows that taking glucomannan 1-1.5 grams three times daily orally for 3-5 weeks, sometimes followed by 1 gram twice daily for an additional 4 weeks, can relieve constipation. As a nonabsorbable dietary fiber, glucomannan appears to have a bulk laxative effect (11294,57783,57795,57816). Taking glucomannan 1.45 grams with lactulose 4.2 grams twice daily orally for 1-3 months appears to relieve constipation during pregnancy (57818). In children with constipation, glucomannan can increase the frequency of bowel movements but does not seem to improve stool consistency. A meta-analysis of 3 clinical trials including 122 children with functional constipation shows that glucomannan leads to 1.4 more stools per week but does not improve stool consistency when compared with placebo or a maltodextrin control (97935). Two studies included in this analysis show that taking a specific glucomannan supplement (Dicoplus, Dicofarm) 100 mg/kg once or twice daily (maximum daily dose 5 grams) along with fluids for up to 12 weeks relieves constipation in children (11295,57775). However, the other clinical study included in the analysis shows that taking a different glucomannan supplement (Dicoman Junior, Vitis Pharma) 1.26 grams twice daily for 4 weeks does not improve constipation in children (92005).
• Diabetes. Limited clinical research suggests that glucomannan may improve glycemic control and lipid profiles in patients with type 2 diabetes. Details: Taking glucomannan orally seems to reduce serum cholesterol and blood glucose levels in patients with type 2 diabetes (183,11357,11359,57791,57797,57798,112702). Most clinical research shows that a glucomannan dose of 3-15 grams daily for 4-12 weeks may reduce fasting blood glucose (183,11357,57791,57797,111225). Eating cookies containing glucomannan 0.5-0.7 grams per 100 kcal for 3 weeks has also been used (11358,11359,57797). Accordingly, a meta-analysis of 5 mostly small, low-quality clinical studies in adults with type 2 diabetes, that includes several of these studies, shows that taking glucomannan 1.2-15 grams daily for 4-16 weeks modestly improves fasting blood glucose when compared with placebo or wheat bran. This analysis also shows that taking glucomannan modestly improves 2-hour post-prandial glucose, total cholesterol, and low-density lipoprotein (LDL) levels but not triglycerides (112702). In healthy people, adding a specific glucomannan supplement (PolyGlycopleX, InovoBiologic Inc.) as granules, 2.5-7.5 grams before meals, or as capsules 3-6 grams with meals, can reduce the glycemic index of starchy foods (92003,92007). Also, taking this glucomannan product reduces postprandial glucose in a dose-dependent fashion in healthy people (92002,92007). However, the interpretation of this evidence is limited by low-quality research and variations in dosages and formulations.
• Hyperlipidemia. Most clinical research shows that glucomannan can reduce cholesterol levels in healthy people and those with hyperlipidemia. Details: Although some conflicting evidence exists (57794), most research shows that taking glucomannan orally can improve lipid levels in healthy adults, children and adults with hyperlipidemia, and adults with diabetes (178,11357,11358,11359,57779,57781,57784,57791,57799,97936)(112702). Meta-analyses of clinical research show that taking glucomannan 2.5-15.1 grams daily for up to 12 weeks can reduce total cholesterol by 19 mg/dL, low-density lipoprotein (LDL) cholesterol by 13-16 mg/dL, non-high-density lipoprotein cholesterol by 12 mg/dL, and triglycerides by 11 mg/dL when compared with a control (57797,97936). Clinical research has not demonstrated a dose-response relationship, and the most common glucomannan doses are 5-10 grams daily for up to 6 weeks for adults and 2-3 grams daily in divided doses for up to 8 weeks for children (11358,11359,57797,97936).

• Dumping syndrome. It is unclear if oral glucomannan is beneficial in patients with dumping syndrome. Details: Preliminary clinical research shows that taking glucomannan (Propol, Pharmacia) 2.6 or 5.2 grams as a single dose reduces the incidence of reactive hypoglycemia following an oral glucose load in adult patients with previous gastric surgery (57805). Other preliminary clinical research shows that taking glucomannan improves glucose tolerance, but not glucose absorption, in children experiencing gastric dumping syndrome after gastric surgery (57804).
• Hypertension. It is unclear if oral glucomannan is beneficial in patients with hypertension. Details: Preliminary clinical research in patients with hypertension shows that eating cookies containing 0.7 grams of glucomannan per 100 kcal, for a total dose of up to 13 grams of glucomannan daily for 3 weeks, can lower systolic blood pressure by about 7% when compared with placebo (11359).
• Hyperthyroidism. It is unclear if oral glucomannan is beneficial in patients with hyperthyroidism. Details: Preliminary clinical research in patients with hyperthyroidism shows that taking glucomannan 1.3 grams twice daily orally, plus methimazole and propranolol for 2 months, reduces serum triiodothyronine (T3) and thyroxine (T4) levels during the first few weeks of therapy, when compared with methimazole and propranolol alone. However, these effects seem to diminish after 6 weeks of therapy (57793).
• Metabolic syndrome. It is unclear if oral glucomannan is beneficial for metabolic syndrome. Details: A small crossover study in adults with metabolic syndrome, defined as impaired glucose tolerance, reduced high-density lipoprotein (HDL) cholesterol, elevated serum triglycerides, and moderate hypertension, shows that consuming biscuits containing glucomannan 0.5 grams per 100 kcal (equivalent to approximately 8-13 grams/day) daily for 3 weeks may modestly improve fasting glucose, but does not improve blood pressure or levels of triglycerides or HDL cholesterol when compared with wheat bran biscuits (11358). However, the 2-week washout period between interventions may be too short to detect differences in some outcomes.
• Obesity. Although some low-quality research shows that oral glucomannan is beneficial for achieving slight improvements in body weight, other research does not support this. Details: Meta-analyses of clinical research on the use of glucomannan for improving body weight and body composition in adults and children with overweight or obesity show mixed results, with one analysis suggesting that taking glucomannan reduces body weight by around 0.8 kg when compared with placebo (57797), and another showing no improvement in body weight (92014). Reasons for these discrepant findings are not clear, but the discrepancies may relate to differences in the study populations and dosing and duration of glucomannan treatment, as well as the low methodological quality of many studies conducted to date. Similar to the pooled analyses described above, individual clinical study results are also mixed. Several small clinical studies show that taking glucomannan can improve body weight, body mass index (BMI), fat mass, and other measures of body composition in children and adults with overweight or obesity, usually when used in combination with a calorie-restricted diet (180,181,182,183,54240,92008,92010,92011,111224,112701). However, conflicting evidence exists (179,57784,57790,57796,92009,112430). Doses that have been used with positive outcomes in adults are 3-4 grams daily, taken in divided doses, for up to 3 months (181,182,183,92008,112701). In children, doses were 2-3 grams daily for 4 months (180). Specific products evaluated include Propylene TM (Natural Alternatives International), PolyGlycopleX (InovoBiologic, Inc.) 3-5 grams 2-3 times daily for 15 weeks, and. Chrombalance 338 mg before each meal and 226 mg in the afternoon daily for 5 weeks (54240,92010,92011). More evidence is needed to rate glucomannan for these uses.

• Dental plaque. It is unclear if oral or topical gum arabic is beneficial for preventing or treating dental plaque. Details: Preliminary clinical research shows that chewing gum arabic for 10 minutes, five times daily for 7 days, reduces dental plaque when compared with chewing sugar-free gum (30220). Another small clinical study in adults with mild or moderate plaque-induced gingivitis shows that applying half a teaspoon of gum arabic powder to the buccal surface of dentogingivial areas for 5 minutes then rinsing with tap water twice daily for 60 days reduces dental plaque in patients with moderate, but not high, plaque accumulation when compared with placebo (111508). Gum arabic has also been evaluated in combination with other ingredients for this purpose. A small clinical study shows that applying a pea-size amount of gel containing gum arabic, barleria, medlar, terminalia, and melia (Gum Tone Gel, Charak Pharma Pvt Ltd.) after brushing for 6 weeks decreases plaque severity when compared with placebo. The gel is similar in effectiveness to chlorhexidine 1% gel (92887). However, it's unclear if these findings are due to gum arabic, other ingredients, or the combination.
• Diabetes. It is unclear if oral gum arabic is beneficial in patients with diabetes. Details: Clinical research in adults with type 2 diabetes who are taking oral antidiabetes medications shows that taking gum arabic powder 30 grams daily in the morning for 3 months modestly reduces fasting blood glucose and glycated hemoglobin (HbA1c) when compared with baseline. Gum arabic also modestly reduces low-density lipoprotein (LDL) cholesterol levels, body mass index, and hip circumference, but not waist circumference or blood pressure, when compared with baseline (98700,99098). The validity of these findings is limited by the lack of a comparison to the placebo group.
• Gingivitis. It is unclear if topical gum arabic is beneficial in patients with gingivitis. Details: A small clinical study in adults with mild or moderate plaque-induced gingivitis shows that applying half a teaspoon of gum arabic powder to the buccal surface of dentogingivial areas for 5 minutes then rinsing with tap water twice daily for 60 days reduces gingival inflammation in patients with mild, but not moderate, gingivitis when compared with placebo (111508). Another small clinical study in patients with chronic gingivitis shows that applying a pea-size amount of gel containing a mixture of ingredients including gum arabic, barleria, medlar, terminalia, and melia (Gum Tone Gel, Charak Pharma Pvt Ltd.) after brushing for 6 weeks decreases gingivitis severity when compared with placebo. The gel was no better than using chlorhexidine 1% gel (92887). However, it's unclear if these findings are due to gum arabic, other ingredients, or the combination.
• Hypercholesterolemia. It is unclear if oral gum arabic helps to reduce high cholesterol levels. Details: One small clinical study in patients with hypercholesterolemia shows that taking gum arabic 5 grams twice daily for 4 weeks does not seem to affect plasma lipid levels when compared with baseline (8072).
• Irritable bowel syndrome (IBS). Although there is interest in using oral gum arabic for IBS, there is insufficient reliable information about the clinical effects of gum arabic for this condition.
• Kidney failure. Although there is interest in using oral gum arabic for kidney failure, there is insufficient reliable information about the clinical effects of gum arabic for this condition.
• Metabolic syndrome. It is unclear if oral gum arabic is beneficial for preventing metabolic syndrome. Details: One small clinical study in healthy adults at risk for metabolic syndrome shows that taking gum arabic 20 grams daily for 12 weeks modestly reduces blood pressure and increases fat-free mass when compared with baseline, but not when compared with taking pectin 1 gram. There were no changes in weight, glycated hemoglobin, or cholesterol levels (105039).
• Obesity. It is unclear if oral gum arabic is beneficial for promoting weight loss. Details: One small clinical study in healthy adults shows that taking powdered gum arabic 18 grams in the morning and 12 grams in the evening for 6 weeks reduces body mass index by 0.32 kg/m2 and body fat percentage by about 2% when compared with placebo. Body weight was also reduced by 1.2%, but this was not significant when compared with placebo (18237). It is unclear if gum arabic is beneficial in individuals with obesity.
• Peristomal lesions. It is unclear if topical gum arabic is beneficial for preventing peristomal lesions in patients with a colostomy bag. Details: Preliminary clinical research in infants shows that applying a thick layer of gum arabic gel to peristomal skin before attaching a colostomy bag twice daily for 4 weeks decreases the incidence of postoperative peristomal dermatitis by about 78% when compared with zinc sulfate ointment (92886).
• Sickle cell disease. It is unclear if oral gum arabic is beneficial in patients with sickle cell disease. Details: Preliminary clinical research in patients with sickle cell disease shows that taking gum arabic powder 30 grams daily for 12 weeks does not improve most markers of liver and kidney function in these patients. While an improvement in direct bilirubin levels was observed when compared to baseline, no significant changes in serum levels of total bilirubin, albumin, protein, liver enzymes, urea, or creatinine were reported (102087). However, in this same group of patients, gum arabic did reduce levels of total cholesterol by 8 mg/dL, low-density lipoprotein (LDL) cholesterol by 5 mg/dL, and triglycerides by 12 mg/dL when compared with baseline. Significant improvements in high-density lipoprotein (HDL) cholesterol were lacking (102088). This research is limited by the lack of a control group, Also, it is unclear whether gum arabic can improve clinical outcomes in patients with sickle cell disease. More evidence is needed to rate the effectiveness of gum arabic for these uses.

• Asthma. There is some evidence that consumption of vitamin C-rich citrus fruits, including kiwi and others, might improve lung function in people with asthma. Intake of citrus fruits 1-2 times per week has produced this benefit in some studies (6049,6055,6056). However, other studies have not found this benefit (6057,6058).
• Constipation. Preliminary clinical research shows that consuming two kiwi fruits daily for 4 weeks increases the number of complete spontaneous bowel movements from 2.2 to 4.4 per week, and improves bothersomeness and satisfaction, but not straining, when compared with baseline in adults with constipation (57530). The validity of this finding is limited by the lack of a comparator group.
• Hypertension. Preliminary clinical research shows that consuming three kiwi fruits daily for 8 weeks reduces 24-hour ambulatory systolic blood pressure by 3.6 mmHg and diastolic blood pressure by 1.9 mm Hg in patients with mild hypertension when compared with those consuming one apple daily (57648).
• Irritable bowel syndrome (IBS). Preliminary clinical research shows that consuming two kiwi fruits daily for 4 weeks decreases bowel transit time by approximately 8 hours and increases defecation frequency in patients with constipation-predominant IBS when compared to baseline. However, fecal volume does not appear to change (57571). Other preliminary clinical research in patients with constipation-predominant IBS shows that consuming three kiwi fruits daily for 4 weeks increases the number of complete spontaneous bowel movements per week by around 2.5 and improves symptoms of constipation and pain when compared to baseline (103293). The validity of these findings is limited by the lack of control groups. More evidence is needed to rate kiwi for these uses.

• Common cold. Preliminary clinical research shows that taking a specific larch arabinogalactan extract (ResistAid, Lonza Ltd.) 4.5 grams daily for 12 weeks does not significantly decrease the number, intensity, or symptoms of common colds when compared with placebo in patients who frequently suffer from colds. However, larch arabinogalactan appears to increase the percentage of patients who experience no cold episodes. About 42% of patients receiving larch arabinogalactan extract had no cold episodes, compared to only 28% of patients receiving placebo (93104).
• Hyperlipidemia. Preliminary clinical research shows that taking larch arabinogalactan 8.4 grams daily for 6 months, or 15-30 grams daily for 6 weeks, does not significantly lower total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, apolipoprotein B (apo B), apolipoprotein A-1, body weight, blood pressure, or glucose levels in healthy people (15617,15620). It is not known if larch arabinogalactan lowers lipid levels in patients with hyperlipidemia. More evidence is needed to rate larch arabinogalactan for these uses.

ORAL DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Theoretically, glucomannan may decrease absorption of drugs taken orally.  Details Due to its viscosity and bulking effects, there is concern that glucomannan can decrease the absorption of oral drugs. A small clinical study in healthy volunteers shows that taking glyburide 2.5 mg plus glucomannan 3.9 grams with breakfast reduces plasma levels of glyburide when compared with breakfast and glyburide alone (11360). In addition, animal research demonstrates this effect on amoxicillin, but shows increased absorption of metronidazole. This mouse model also demonstrates that metronidazole elimination is prolonged, but amoxicillin elimination is enhanced by 38%; glucomannan may also affect the distribution of some drugs (112703). To avoid changes in absorption, take glucomannan 30-60 minutes after taking oral drugs.

AMOXICILLIN (Amoxil, Trimox) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Gum arabic can reduce the absorption of amoxicillin.  Details A small study in healthy volunteers shows that taking amoxicillin and gum arabic concurrently significantly reduces the absorption of amoxicillin. Separate doses of amoxicillin from gum arabic by at least 2 hours (12654).

ORAL DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, gum arabic can alter the absorption of oral drugs due to its fiber content.  Details Gum arabic has been used as a suspending osmotic agent in drug formulations. It might improve bioavailability of water-insoluble drugs like naproxen, but reduce absorption of polar drugs like amoxicillin (12654,104058). To avoid changes in absorption, take gum arabic 30-60 minutes after oral medications.

General ...Orally, bananas are well tolerated when consumed as food.
Most Common Adverse Effects:
Orally: Bloating, cramping, gas.
Topically: Urticaria.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis, intestinal obstruction.

Endocrine ...In one case report, an adolescent girl who consumed nothing other than 20 bananas daily developed hyperkalemia and hyperdopaminemia. These changes in the blood resulted in pseudoaldosteronism and dysthymia (93780).

Gastrointestinal ...Orally, banana starch isolated from green bananas has resulted in bloating, gas, cramping, and softer feces (93448,93449,110619). When consumed prior to exercise, fullness and bloating during exercise have been reported (93459). In children, nausea, vomiting, and abdominal distension have been reported when banana is used in the treatment of diarrhea (93461). Cases of intestinal obstruction due to banana seeds have been reported (93777).
In one case report, food protein-induced enterocolitis syndrome (FPIES) has been associated with banana consumption (93778).

Immunologic ...Orally, banana has been reported to cause allergic reaction, including urticaria and redness, abdominal pain and nausea, dyspnea (93779,93781,93782,93797,93798,93803), and anaphylaxis (93783,93793,93802,93803). Topically, contact urticara has also been reported (93784). Skin testing is not always accurate, even for patients with severe banana allergy (93793).

Psychiatric ...Orally, high banana consumption has been associated with a higher likelihood of depressive symptoms in females, but not males, in a cross-sectional study of the general Chinese adult population (106471).

General ...Orally, glucomannan is generally well tolerated when taken with plenty of water or other liquid.
Most Common Adverse Effects:
Orally: Abdominal pain, bloating, constipation, diarrhea, flatulence, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Choking and esophageal or gastrointestinal obstruction, especially when taken as a dry powder or in tablet form.

Gastrointestinal ...Orally, glucomannan can cause gastrointestinal disturbances, including abdominal pain, bloating, constipation, diarrhea, flatulence, nausea, and vomiting, especially when taken in doses of more than 3 grams daily (57781,57784,92004,92010,92011,97935,106411). Esophageal and gastrointestinal obstructions have been reported when dry glucomannan-containing products are taken with insufficient fluid (11293,57785,106410).

Hepatic ...Acute cholestatic hepatitis occurred in a 31-year-old male after taking glucomannan orally for 45 days (57777). He was also taking other supplements, including garlic and chitosan, so it is unclear whether the hepatitis was due to glucomannan, other supplements, or the combination.

Pulmonary/Respiratory ...Cases of occupational respiratory disorders, including respiratory sensitization and bronchial asthma, have been reported in workers exposed to glucomannan (57789,57810).
