Below is general information about the safety of the known ingredients contained in the product Springboard Imu-A. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when consumed in amounts commonly found in foods. Ceylon cinnamon has Generally Recognized As Safe (GRAS) status in the US for use as a spice or flavoring agent (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Ceylon cinnamon 0.5-3 grams daily has been safely used in studies lasting up to 6 months (4,12,97248,97250,99874). ...when used as a mouth rinse for up to 15 days (92071). There is insufficient reliable information available about the safety of Ceylon cinnamon when used orally in greater amounts or for longer periods. Ceylon cinnamon contains trace amounts of coumarin (108260). In very high doses, coumarin can cause hepatotoxicity (15302). However, since the amount of coumarin in Ceylon cinnamon is negligible, it is unlikely to cause toxic effects (89652,92072,92073).
PREGNANCY: LIKELY SAFE
when consumed in amounts commonly found in foods (4912).
PREGNANCY: LIKELY UNSAFE
when used orally in amounts greater than those found in foods.
Fetal abnormalities have been reported in animals (4,12).
LACTATION: LIKELY SAFE
when consumed in amounts commonly found in foods (4912).
There is insufficient reliable information available about the safety of Ceylon cinnamon in amounts greater than those found in foods.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Coriander and coriander oil have Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes (12). ...when used topically and appropriately. Coriander oil 6% ointment has been used with apparent safety twice daily for up to 28 days (97874).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid amounts in excess of those found in foods.
LIKELY SAFE ...when used orally and appropriately, short-term. Various liquid extracts of Echinacea purpurea have been used safely for up to 10 days, including EchinaGuard (Madaus AG) 20 drops every 2 hours for 1 day, then three times daily (10320), or Echinilin (Inovobiologic Inc.) 40 mL in divided doses for 1 day, then 15 mL in divided doses daily thereafter (12355,20062). Other liquid extracts have been used safely for relatively longer periods, including Echinaforce (A. Vogel Bioforce AG) 2.4 grams daily for 4 months or 1.6 grams daily for 6 months (7087,18225), and Echinacin (Madaus AG) 5 mL twice daily for 10 days, or 4 mL twice daily for 8 weeks (3282,10802). Specific solid dosage forms of echinacea that have been used safely for up to 10 days include Echinacea purpurea above-ground parts (EchinaFresh, Enzymatic Therapy) 300 mg daily (11970), and mixtures of Echinacea purpurea and Echinacea angustifolia herb in divided doses of 6 grams to 10.5 grams for 1 day then 3 grams to 5.1 grams daily (10800,17519,20059). A specific Echinacea angustifolia extract (ExtractumPharma ZRT) has also been used with apparent safety at a dose of 40 mg once or twice daily for up to 7 days (20064,103233). An Echinacea purpurea product (Natures Resource) has been used safely at a dose of 1.8 grams daily for 8 weeks (17521), and echinacea (Puritan's Pride) has been used safely at 8 grams daily for 28 days (20066).
POSSIBLY SAFE ...when used topically, short-term. A specific cream (Linola Plus Cream, Dr. August Wolff GmbH & Co.) containing echinacea extract (WO 3260) has been applied to the skin safely 2-3 times daily for up to 12 weeks (97499). There is insufficient reliable evidence about the safety of echinacea when used parenterally.
CHILDREN: POSSIBLY SAFE
when used orally, short-term.
Some clinical research shows that an extract of the above-ground parts of Echinacea purpurea (EC31J2, Echinacin Saft, Madaus AG) in a dose of 3.75 mL twice daily (for ages 2 years to 5 years) or 7.5 mL twice daily (for ages 6 years to 11 years) is safe when used for up to 10 days (4989). However, about 7% of children experienced a rash after taking echinacea, which might have been caused by an allergic reaction (4989). There is concern that allergic reactions could be severe in some children. The Medicines and Healthcare Products Regulatory Agency in the United Kingdom recommends against the use of oral echinacea products in children under 12 years of age due to this risk of allergic reaction (18207). In contrast, another clinical study in children 4-12 years old shows that a specific Echinacea purpurea product (Echinaforce Junior, A. Vogel) does not cause allergic or urticarial reactions more frequently than vitamin C (105719).
PREGNANCY: POSSIBLY SAFE
when used orally, short-term.
There is preliminary evidence that mothers can safely use echinacea in the form of E. purpurea or E. angustifolia solid dosage forms, 250-1000 mg daily, or tinctures, up to 30 drops daily, for 5 days to 7 days during the first trimester without adversely affecting the fetus (7056,13418,15123). There is insufficient reliable information available about the safety of echinacea when used for longer than 7 days.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately as a single dose (260,261). There is insufficient reliable information available about the safety of goldenseal when used as more than a single dose.
CHILDREN: LIKELY UNSAFE
when used orally in newborns.
The berberine constituent of goldenseal can cause kernicterus in newborns, particularly preterm neonates with hyperbilirubinemia (2589).
PREGNANCY: LIKELY UNSAFE
when used orally.
Berberine is thought to cross the placenta and may cause harm to the fetus. Kernicterus has developed in newborn infants exposed to goldenseal (2589).
LACTATION:
LIKELY UNSAFE when used orally.
Berberine and other harmful constituents can be transferred to the infant through breast milk (2589). Use during lactation can cause kernicterus in the newborn and several resulting fatalities have been reported (2589).
POSSIBLY UNSAFE ...when used orally. The safety of pau d'arco in typical doses is unclear; however, serious toxicities have been found with high doses of the lapachol constituent (91939). In patients with cancer, doses of lapachol above 1.5 grams daily were associated with significant gastrointestinal toxicities and an increased risk of bleeding (91939). There is insufficient reliable information available about the safety of pau d'arco when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used orally in typical doses.
Animal studies have found that lapachol, a constituent of pau d'arco, has teratogenic and abortifacient effects (68314,68315); avoid using. There is insufficient reliable information available about the safety of pau d'arco when used topically in pregnancy; avoid using.
LACTATION:
Insufficient reliable information available; avoid using.

Evidence from animal research suggests that coriander fruit can lower blood pressure (46221).
|
Theoretically, coriander might cause additive sedative effects when taken with CNS depressants.
Details
Evidence from animal research suggests that coriander fruit extract has sedative effects (46184).
|
Theoretically, coriander might increase the risk of photosensitivity when taken with photosensitizing drugs.
Details
Evidence from in vitro research suggests that coriandrin, a constituent of coriander, has photosensitizing effects (46228).
|
Echinacea can increase plasma levels of caffeine by inhibiting its metabolism.
Details
Echinacea seems to increase plasma concentrations of caffeine by around 30% (12155). This is likely due to inhibition of cytochrome P450 1A2 (CYP1A2) by echinacea.
|
Echinacea might inhibit the metabolism of CYP1A2 and increase plasma levels of some drugs.
Details
Echinacea appears to inhibit CYP1A2 enzymes in humans. Additionally, echinacea seems to increase plasma concentrations of caffeine, a CYP1A2 substrate, by around 30% (12155). Theoretically, echinacea might increase levels of other drugs metabolized by CYP1A2.
|
Echinacea may induce hepatic CYP3A4 and inhibit intestinal CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Details
Several clinical trials have shown that taking echinacea for up to one month does not significantly affect the metabolism of various CYP3A4 substrates, including midazolam, docetaxel, etravirine, lopinavir-ritonavir, and darunavir-ritonavir (13712,48618,88164,88165). However, other clinical research shows that echinacea may increase the clearance of midazolam, suggesting that echinacea might induce CYP3A4 (48618). The discrepancy is thought to be due to differing effects of echinacea on intestinal versus hepatic CYP3A4 enzymes. Echinacea appears to induce hepatic CYP3A4 but inhibit intestinal CYP3A4 (12155). In some cases, these effects might cancel each other out, but in others, drug levels may be increased or decreased depending on the level of effect at hepatic and intestinal sites. The effect of echinacea on CYP3A4 activity may differ depending on the CYP3A4 substrate (6450,11026,88162,88167).
|
Theoretically, echinacea may interfere with the metabolism of darunavir; however, a small clinical study found no effect.
Details
Darunavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but administration of an E. purpurea root extract (Arkocapsulas Echinacea, Arkopharma) 500 mg four times daily for 14 days did not affect darunavir/ritonavir pharmacokinetics in 15 HIV-infected patients (88163,93578).
|
Theoretically, echinacea may interfere with the metabolism of docetaxel; however, a small clinical study found no effect.
Details
Docetaxel is metabolized by cytochrome P450 3A4 (CYP3A4). Echinacea has variable effects on CYP3A4, but taking E. purpurea whole plant extract (Echinaforce, A. Vogel Biopharma AG) 20 drops three times daily for 2 weeks did not alter the pharmacokinetics of docetaxel in one clinical study (88164).
|
Echinacea may increase levels of etoposide.
Details
In one report, concomitant use of etoposide and echinacea was associated with more severe thrombocytopenia than the use of etoposide alone, suggesting inhibition of etoposide metabolism (20082). Etoposide is a cytochrome P450 3A4 (CYP3A4) substrate. Echinacea has variable effects on CYP3A4, but some studies have reported inhibition of the enzyme (6450,11026,12155,88162,88167).
|
Theoretically, echinacea may interfere with the metabolism of etravirine; however, a small clinical study found no effect.
Details
|
Echinacea has immunostimulant activity which may interfere with immunosuppressant therapy.
Details
|
Theoretically, echinacea may interfere with the metabolism of lopinavir; however, a small clinical study found no effect.
Details
Lopinavir is metabolized by cytochrome P450 3A4 (CYP3A4) and is administered with the CYP3A4 inhibitor ritonavir to increase its plasma concentrations. Echinacea has variable effects on CYP3A4, but taking E. purpurea (Echinamide, Natural Factors Nutritional Products, Inc.) 500 mg three times daily for 14 days did not alter the pharmacokinetics of lopinavir/ritonavir in healthy volunteers (48618,93578).
|
Theoretically, echinacea may increase the metabolism of intravenous midazolam.
Details
Echinacea induces hepatic CYP3A4 and might decrease plasma levels of midazolam by about 20%, reducing the effectiveness of intravenous midazolam (12155). Echinacea also appears to inhibit intestinal CYP3A4, which could theoretically increase the bioavailability of oral midazolam. This may cancel out the decrease in availability caused by induction of hepatic CYP3A4, such that overall plasma levels after oral administration of midazolam are not affected by echinacea.
|
Echinacea seems to increase the clearance of warfarin, although the effect may not be clinically significant.
Details
Preliminary clinical research in healthy male volunteers suggests that taking echinacea increases the clearance of the active S-isomer of warfarin after a single dose of warfarin, but there was not a clinically significant effect on the INR (20083).
|
Theoretically, goldenseal might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, goldenseal might increase the risk of hypoglycemia when used with antidiabetes drugs.
Details
|
Theoretically, goldenseal might increase the risk of hypotension when taken with antihypertensive drugs.
Details
Goldenseal contains berberine. Animal research shows that berberine can have hypotensive effects (33692,34308). Also, an analysis of clinical research shows that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone (91956). However, this effect has not been reported with goldenseal.
|
Theoretically, goldenseal might increase the sedative effects of CNS depressants.
Details
|
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2C9.
Details
In vitro research shows that goldenseal root extract can modestly inhibit CYP2C9. This effect may be due to its alkaloid constituents, hydrastine and berberine (21117). However, this effect has not been reported in humans.
|
Goldenseal might increase serum levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2E1.
Details
In vitro research shows that goldenseal root extract can inhibit the activity of CYP2E1 (94140). However, this effect has not been reported in humans.
|
Goldenseal might increase serum levels of drugs metabolized by CYP3A4.
Details
Most clinical and in vitro research shows that goldenseal inhibits CYP3A4 enzyme activity and increases serum levels of CYP3A4 substrates, such as midazolam (6450,13536,21117,91740,111725). However, in one small clinical study, goldenseal did not affect the levels of indinavir, a CYP3A4 substrate, in healthy volunteers (10690,93578). This is likely due to the fact that indinavir has a high oral bioavailability, making it an inadequate probe for CYP3A4 interactions (13536,91740) and/or that it is primarily metabolized by hepatic CYP3A, while goldenseal has more potential to inhibit intestinal CYP3A enzyme activity (111725). Both goldenseal extract and its isolated constituents berberine and hydrastine inhibit CYP3A, with hydrastine possibly having more inhibitory potential than berberine (111725).
|
Theoretically, goldenseal might increase serum levels of dextromethorphan.
Details
Goldenseal contains berberine. A small clinical study shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan (34279).
|
Goldenseal might increase serum levels of digoxin, although this effect is unlikely to be clinically significant.
Details
Clinical research shows that goldenseal modestly increases digoxin peak levels by about 14% in healthy volunteers. However, goldenseal does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC) (15132). This suggests that goldenseal does not cause a clinically significant interaction with digoxin. Digoxin is a P-glycoprotein substrate. Some evidence suggests that goldenseal constituents might affect P-glycoprotein; however, it is unclear whether these constituents inhibit or induce P-glycoprotein.
|
Theoretically, goldenseal might decrease the conversion of losartan to its active form.
Details
Goldenseal contains berberine. A small clinical study shows that berberine inhibits cytochrome P450 2C9 (CYP2C9) activity and reduces the metabolism of losartan (34279). However, this effect has not been reported with goldenseal.
|
Theoretically, goldenseal might reduce blood levels of metformin.
Details
In vitro research shows that goldenseal extract decreases the bioavailability of metformin, likely by interfering with transport, intestinal permeability, or other processes involved in metformin absorption. It is unclear which, if any, of metformin's transporters are inhibited by goldenseal. Goldenseal does not appear to alter the clearance or half-life of metformin (105764).
|
Theoretically, goldenseal might reduce the therapeutic effects of oseltamivir by decreasing its conversion to its active form.
Details
In vitro evidence suggests that goldenseal reduces the formation of the active compound from the prodrug oseltamivir (105765). The mechanism of action and clinical relevance is unclear.
|
Theoretically, goldenseal might increase or decrease serum levels of P-glycoprotein (P-gp) substrates.
Details
There is conflicting evidence about the effect of goldenseal on P-gp. In vitro research suggests that berberine, a constituent of goldenseal, modestly inhibits P-gp efflux. Other evidence suggests that berberine induces P-gp. In healthy volunteers, goldenseal modestly increases peak levels of the P-gp substrate digoxin by about 14%. However, it does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC) (15132). This suggests that goldenseal is not a potent inhibitor of P-gp-mediated drug efflux. Until more is known, goldenseal should be used cautiously with P-gp substrates.
|
Theoretically, goldenseal might increase the sedative effects of pentobarbital.
Details
Animal research shows that berberine, a constituent of goldenseal, can prolong pentobarbital-induced sleeping time (13519). However, this effect has not been reported with goldenseal.
|
Theoretically, goldenseal might increase serum levels of tacrolimus.
Details
Goldenseal contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of tacrolimus dosing to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL (91954).
|
Theoretically, pau d'arco might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
In vitro research shows that pau d'arco reduces platelet aggregation and may interfere with vitamin K (18057,68319). One clinical study shows that taking the lapachol constituent of pau d'arco in doses above 1.5 grams daily increases the risk of bleeding (91939). The effects of whole pau d'arco or pau d'arco extract in humans are unclear.

Below is general information about the adverse effects of the known ingredients contained in the product Springboard Imu-A. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, Ceylon cinnamon is generally well tolerated, and adverse reactions are uncommon.
Most Common Adverse Effects:
Orally: Bloating, dyspepsia, nausea.
Topically: Allergic dermatitis, irritation of mucous membranes and skin.
Dermatologic
...Orally, a case of systemic contact dermatitis has been reported in a patient who consumed cinnamon (type not specified) after being previously sensitized to cinnamyl alcohol via cutaneous exposure (95599).
In a small study of oral Ceylon cinnamon, two patients reported itching (104520). In another small study, two patients reported rashes (108263).
Topically, cinnamon oil can cause skin irritation and allergic dermatitis, probably due to cinnamaldehyde which makes up 60% to 80% of cinnamon oil (2537,12635,92071,95596,95599). In one case report, a 16-year-old female experienced worsening dermatitis after using a homemade facial scrub containing cinnamon powder (type not specified). Symptoms improved after discontinuation of the scrub (95596). Several cases of intraoral allergic contact dermatitis have been reported in patients consuming cinnamon (type not specified) or using products containing constituents of cinnamon (95598).
Gastrointestinal ...Orally, gastrointestinal side effects such as heartburn, nausea, bloating, and dyspepsia have been reported (97250).
Hematologic ...Orally, a case of postoperative hemorrhage is reported in a 49-year-old patient after taking Ceylon cinnamon 1 tablespoon daily for 10 months. One day post-colectomy, the patient had an INR of 1.59 and intraabdominal bleeding that required exploratory laparotomies, blood transfusion, and fresh frozen plasma. Ultimately, the patient was discharged (112421).
Hepatic ...While there is concern about the coumarin content in cassia cinnamon increasing the risk for hepatic adverse effects and bleeding, the amount of coumarin in Ceylon cinnamon is negligible and unlikely to cause toxic effects (89652,92072,92073). In one case report, a 73-year-old female taking rosuvastatin for several months developed elevated liver function tests (LFTs), abdominal pain, nausea, and vomiting after taking cinnamon (unknown dose and type) for 7 days. The acute hepatitis and elevated LFTs resolved after stopping both cinnamon and rosuvastatin. The patient was later able to resume rosuvastatin without recurrence (97249).
General
...Orally and topically, coriander seems to be well tolerated.
Most Common Adverse Effects:
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Dermatologic ...Topically, coriander can cause pruritus and a burning sensation (97874).
Immunologic ...A case of anaphylactic reaction characterized by generalized urticaria, conjunctivitis, oropharyngeal angioedema, and bronchospasms has been reported in a 25-year-old spice worker who consumed food containing coriander fruit. The digestive spice allergy was attributed to sensitization to coriander caused by occupational exposure to coriander fruit, powder, and dust (46192). Also, cases of rhinitis and symptoms of asthma have been reported for patients exposed to dust from coriander spice, particularly people working with spices in the food industry (46226,46245). Like other members of the Apiaceae/Umbelliferae (carrot family), coriander can cause contact dermatitis (19). A case of occupational protein contact dermatitis has been reported for an individual exposed to coriander fruit (46168).
General
...Orally, echinacea is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, heartburn, nausea and vomiting, rashes, and stomach upset.
Serious Adverse Effects (Rare):
Orally: Severe allergic reactions and hepatitis have been reported.
Dermatologic ...Itching, urticaria, tingling, and allergic rashes have been reported with various echinacea preparations (8225,12355,17519,20059,20077,101592,111530,111540). In a study of children aged 2-11 years, rash occurred in about 7% of children treated with an extract of the above-ground parts of E. purpurea (EC31J2, Echinacin Saft, Madaus AG), compared with about 3% of those treated with placebo (4989,95652). There is concern that allergic reactions could be severe in some children. The Medicines and Healthcare Products Regulatory Agency in the United Kingdom (UK) recommends against the use of oral echinacea products in children under 12 years of age due to this risk of allergic reaction (18207). However, another study in children 4-12 years old shows that a specific E. purpurea product (Echinaforce Junior, A. Vogel) did not cause allergic or urticarial reactions more frequently than vitamin C (105719).
Gastrointestinal ...Gastrointestinal adverse effects include nausea and vomiting, abdominal pain, stomach upset, heartburn, diarrhea, and constipation (10802,11970,12355,13419,17519,20059,48680,105719,106626). An unpleasant taste, dry mouth, and burning, tingling or numbness of the tongue also occur (11970,12355,17519,20059,20070,20077).
Hematologic ...A 51-year-old female presented with leukopenia after taking echinacea 450 mg three times daily for 2 months, along with ginkgo biloba, multivitamins, and calcium. Her leukocyte count recovered upon stopping these supplements, but dropped again when she restarted echinacea alone about a year later. The problem resolved when echinacea was stopped permanently (48533). A 32-year-old male presented with severe thrombotic thrombocytopenic purpura (TTP) about 2 weeks after using an extract of E. pallida to treat a cold. He required admission to an intensive care unit and extensive plasmapheresis. The authors speculate that immunostimulant effects of echinacea induced or exacerbated the TTP (48572).
Hepatic
...Although uncommon, cases of echinacea-induced hepatitis have been reported.
One case report describes acute cholestatic autoimmune hepatitis in a 45-year-old male who had been taking an echinacea root extract 1500 mg daily for about 2 weeks. He presented with significantly elevated liver function tests (LFTs), elevated immunoglobulin G (IgG) levels, and a positive test for anti-smooth muscle antibodies, indicating an autoimmune process. Elevated LFTs and IgG levels returned to normal within one month of stopping echinacea (17518). Another case report describes acute cholestatic hepatitis in a 44-year-old male who had taken echinacea root tablets 600 mg daily for 5 days to treat flu-like symptoms. He presented with elevated LFTs, prothrombin time, and international normalized ratio (INR). His condition gradually improved after stopping echinacea, and his LFTs normalized within 3 months (91528).
Seven cases of hepatitis associated with echinacea use were reported to the Australian Adverse Drug Reactions Advisory Committee between 1979 and 2000, but specific details are lacking (8225).
One case report describes acute liver failure in a 2 year-old child who had been given about 100 mg of echinacea daily for 2 weeks. The patient presented with jaundice, diarrhea, lethargy, anorexia, and significantly elevated LFTs. A liver biopsy showed hepatocyte swelling, spotty necrosis, and inflammatory infiltrate with eosinophils. A full recovery was made over a 2-week period (88166).
Immunologic
...Allergic reactions, including urticaria, runny nose, dyspnea, bronchospasm, acute asthma, angioedema, and anaphylaxis, have been reported with various echinacea preparations (638,1358,8225).
Atopic individuals and those sensitive to other members of the Asteraceae family (ragweed, chrysanthemums, marigolds, daisies) seem to be at higher risk for these reactions (1358,8225).
A case report describes a 36-year-old female who presented with muscle weakness, electrolyte abnormalities, renal tubular acidosis, fatigue, and dry mouth and eyes after taking echinacea, kava, and St. John's Wort for 2 weeks., She also had a positive antinuclear antibody (ANA) test, with elevated anti-dsDNA antibodies SSA and SSB. Sjogren syndrome was diagnosed; the authors hypothesize that it may have been triggered by the immunostimulant effects of echinacea (10319). A 55-year-old male with a history of pemphigus vulgaris in remission for about a year experienced a flare of the disease after taking an echinacea supplement for one week. After stopping echinacea, medical treatment resulted in partial control of the disease (12171). Another case report describes a 58-year-old male who presented with marked eosinophilia and elevated immunoglobulin E (IgE) levels while taking an echinacea supplement. He required prednisone therapy until he stopped taking echinacea 3 years later, at which time his eosinophils and IgE normalized (48623). A 41-year-old male experienced four episodes of erythema nodosum, each occurring after he had taken echinacea for early symptoms of influenza. After stopping echinacea, he had no further exacerbations of erythema nodosum, suggesting that it had been triggered by the immunostimulant effects of echinacea (7057).
Musculoskeletal ...Reports of arthralgia and myalgia have been associated with echinacea (13418).
Neurologic/CNS ...Headache has been reported in people taking various echinacea preparations orally (3282,11970,17519,20059,20064). Dizziness has also been reported (3282,8225,11970). In one study using an alcoholic extract of the above-ground parts of E. purpurea (EC31J0, Echinacin, Madaus AG), somnolence and a tendency to aggressiveness were reported (3282).
General
...There is limited reliable information available about the safety of goldenseal when used in more than a single dose.
Berberine, a constituent of goldenseal, is generally well tolerated when used orally.
Most Common Adverse Effects:
Orally: Berberine, a constituent of goldenseal, can cause abdominal distension, abdominal pain, bitter taste, constipation, diarrhea, flatulence, headache, nausea, and vomiting.
Dermatologic ...Orally, berberine, a constituent of goldenseal, may cause rash. However, this appears to be rare (34285). A case of photosensitivity characterized by pruritic, erythematous rash on sun-exposed skin has been reported in a 32-year-old female taking a combination product containing goldenseal, ginseng, bee pollen, and other ingredients.
