Below is general information about the safety of the known ingredients contained in the product Acai Berry. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Acai pulp, in a dose of up to 162.5 grams daily, has been used with apparent safety for up to 3 months in clinical research (17731,99400). There is insufficient reliable information available about the safety of acai when used topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when aloe gel is used topically and appropriately. Aloe gel-containing formulations have been safely applied in clinical trials (101,11982,12096,12098,12159,12160,12163,12164,17418)(90123,90124,90127,90128,90129,90131,97320,98816,103305). When included in topical cosmetics, the Cosmetic Ingredient Review Expert Panel concluded that aloe-derived anthraquinone levels should not exceed 50 ppm (90122).
POSSIBLY SAFE ...when aloe gel is used orally and appropriately, short-term. Aloe gel has been safely used in a dose of 15 mL daily for up to 42 days or 100 mL of a 50% solution twice daily for up to 4 weeks (11984,12164). Also, a specific aloe gel complex (Aloe QDM complex, Univera Inc.) has been safely used at a dose of approximately 600 mg daily for up to 8 weeks (90121). ...when aloe extract is used orally and appropriately, short-term. Aloe extract has been used with apparent safety in a dose of 500 mg daily for one month (101579). Also, an aloe extract enriched in aloe sterols has been used with apparent safety in a dose of 500 mg daily for 12 weeks (101577).
POSSIBLY UNSAFE ...when aloe latex is used orally. There is some evidence that anthraquinones in aloe latex are carcinogenic or promote tumor growth, although data are conflicting (6138,16387,16388,91596,91597). In 2002, the US FDA banned the use of aloe latex in laxative products due to the lack of safety data (8229). ...when aloe whole-leaf extract is used orally. Aloe whole-leaf extract that has not been filtered over charcoal still contains anthraquinones. This type of aloe whole-leaf extract is referred to as being "nondecolorized". The International Agency for Research on Cancer has classified this type of aloe whole-leaf extract as a possible human carcinogen (91598,91908). Although filtering aloe whole-leaf extract over charcoal removes the anthraquinones, some animal research suggests that this filtered extract, which is referred to as being "decolorized", may still cause gene mutations (91598). This suggests that constituents besides anthraquinones may be responsible for the carcinogenicity of aloe whole-leaf extract. It should be noted that commercial products that contain aloe whole-leaf extract may be labeled as containing "whole leaf Aloe vera juice" or "aloe juice" (91908).
LIKELY UNSAFE ...when aloe latex is used orally in high doses. Ingesting aloe latex 1 gram daily for several days can cause nephritis, acute kidney failure, and death (8,8961).
CHILDREN: POSSIBLY SAFE
when aloe gel is used topically and appropriately.
Aloe gel-containing formulations have been safely applied in clinical trials (90124,90131).
CHILDREN: POSSIBLY UNSAFE
when aloe latex and aloe whole leaf extracts are used orally in children.
Children younger than 12 years may experience abdominal pain, cramps, and diarrhea (4).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Anthraquinones present in aloe latex and aloe whole leaf extracts have irritant, cathartic, and possible mutagenic effects (4,16387,16388,90122). There are also anecdotal reports and evidence from animal research that anthraquinones or aloe whole leaf extracts might induce abortion and stimulate menstruation; avoid using (4,8,19,90122).
LACTATION: POSSIBLY UNSAFE
when aloe preparations are used orally.
Cathartic and mutagenic anthraquinones present in aloe latex and aloe whole leaf extracts might pass into milk; avoid using (4,19).
LIKELY SAFE ...when the fruit (nut) is consumed in amounts normally found in food.
POSSIBLY UNSAFE ...when the bark is used orally or topically, due to its juglone content (2). When applied topically, juglone-containing bark can cause skin irritation. When used orally on a daily basis, the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12). There is insufficient reliable information available about the safety of the leaf or hull when used orally as a medicine or when applied topically.
PREGNANCY AND LACTATION: LIKELY SAFE
when the fruit (nut) is consumed in amounts normally found in foods.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when the bark is used orally or topically (12); avoid using.
There is insufficient reliable information available about the safety of black walnut leaf or hull when used orally in medicinal amounts during pregnancy or lactation; avoid using.
LIKELY SAFE ...when used orally and appropriately, short-term. Tablets and liquids containing chlorella 3-10 grams or 60-100 mL daily have been safely used in clinical studies lasting 2-3 months (5890,92130,92131). Also, chlorella extract 200-1800 mg daily has been safely used in clinical research for 4-6 weeks (10388,92132). There is insufficient reliable information available about the safety of chlorella when used topically.
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately in medicinal amounts for up to approximately 28 weeks.
A commercially available chlorella supplement (Sun Chlorella A, Sun Chlorella Corp.) has been safely used in doses of 6 grams daily, starting during the 12-18th week of gestation and continuing until delivery (95013).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Ginger has been safely used in multiple clinical trials (721,722,723,5343,7048,7084,7085,7400,7623,11346)(12472,13080,13237,13244,17369,17928,17929,89889,89890,89894)(89895,89898,89899,90102,96252,96253,96259,96260,96669) (101760,101761,101762,103359,107903).
POSSIBLY SAFE ...when used topically and appropriately, short-term (89893,89897).
CHILDREN: LIKELY SAFE
when consumed in the amounts typically found in foods.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately, short-term.
Ginger powder has been used with apparent safety at a dose of up to 750 mg daily for 4 days in girls aged 14-18 years (96255).
PREGNANCY: LIKELY SAFE
when consumed in the amounts typically found in foods.
Ginger is considered a first-line nonpharmacological treatment option for nausea in pregnancy by the American College of Obstetrics and Gynecology (ACOG) (111601). However, it should not be used long-term or without medical supervision and close monitoring.
PREGNANCY: POSSIBLY SAFE
when used for medicinal purposes.
Despite some early reports of adverse effects (721,7083) and one observational study suggesting that taking dried ginger and other herbal supplements during the first 20 weeks of pregnancy marginally increased the chance of stillbirth (96254), most research shows that ginger is unlikely to cause harm to the baby. The risk for major malformations in infants of parents who took ginger when pregnant does not appear to be higher than the baseline rate of 1% to 3% (721,1922,5343,11346,13071,13080,96254). Also, other research suggests that ginger intake during various trimesters does not significantly affect the risk of spontaneous abortion, congenital malformations, stillbirth, perinatal death, preterm birth, low birth weight, or low Apgar scores (18211,90103). Ginger use has been associated with an increase in non-severe vaginal bleeding, including spotting, after week 17 of pregnancy (18211).
LACTATION: LIKELY SAFE
when consumed in the amounts typically found in foods.
There is insufficient reliable information available about the safety of ginger when used for medicinal purposes; avoid amounts greater than those found in foods.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Hyssop, hyssop oil, and hyssop extract have Generally Recognized as Safe (GRAS) status in the US (4912). There is insufficient reliable information available about the safety of hyssop when used in medicinal amounts.
PREGNANCY: LIKELY UNSAFE
when used orally because it might cause uterine stimulant and menstrual stimulant effects (12).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Inulin has Generally Recognized As Safe status (GRAS) in the US (93728).
POSSIBLY SAFE ...when used orally and appropriately in supplemental doses, short-term. Doses of 8-18 grams daily have been used safely for up to 24 weeks (7604,7605,7606,7607,8451,93716,93719,93726,103200,107936,107935,107938). Also, 20 grams daily has been used with apparent safety for up to 3 weeks (96836,96850). There is insufficient reliable information available about the safety of inulin when used long-term.
CHILDREN: LIKELY SAFE
when used orally in amounts commonly found in foods.
Inulin has Generally Recognized As Safe status (GRAS) in the US (93728).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately in supplemental doses, short-term.
Clinical studies have used doses of 3-6 grams daily for 10 days in children 3-6 years of age and 5-13 grams daily for up to 6 months in children 7-15 years of age with apparent safety (96847,110598,110602). ...when used in infant formula. A formula containing chicory fructans (Orafti Synergy1, BENEO GmbH), approximately 50% of which were inulin, has been used with apparent safety in infants for 8-12 months (93717,107937).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (93728).
There is insufficient reliable information available about using inulin in medicinal amounts during pregnancy or lactation; avoid use.
LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods (2406,7772,7773). ...when used orally in supplemental doses. Lycopene supplements have been used safely in doses of 15-45 mg daily for 4 to 6 months (60389,60399,60482,102180,102182,109431). Some limited evidence suggests that 120 mg daily is safe for up to one year (60372).
PREGNANCY: LIKELY SAFE
when consumed in amounts commonly found in foods.
There is insufficient reliable information available about the safety of lycopene supplements during pregnancy. Small, low-quality clinical studies have shown conflicting results about the safety of using lycopene 2-4 mg daily during pregnancy (60337,60428).
LACTATION: LIKELY SAFE
when consumed in amounts commonly found in foods.
There is insufficient reliable information available about the safety of lycopene supplements during lactation; avoid using in amounts greater than those typically found in foods.
LIKELY SAFE ...when the ripe fruit is used orally in amounts commonly found in foods. Papaya has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when the leaf extract is used orally and appropriately in medicinal amounts, short term. The leaf extract has been used with apparent safety in doses of up to 3300 mg daily for up to 5 days (102799,102800). ...when the ripe fruit is used topically and appropriately, short term. The fruit has been applied with apparent safety to the gingiva or skin for up to 10 days (93090,93091).
POSSIBLY UNSAFE ...when the unripe fruit containing papaya latex and raw papain is used orally. Raw papain has been reported to cause esophageal perforation (6,93083). ...when papaya latex is used topically. Papaya latex, which contains raw papain, is a severe irritant and vesicant (6).
PREGNANCY: LIKELY SAFE
when the ripe fruit is consumed in amounts commonly found in foods.
PREGNANCY: POSSIBLY UNSAFE
when the unripe fruit containing papaya latex is used orally; avoid using.
There is some concern that crude papain, a constituent of papaya latex, is teratogenic and embryotoxic (6); however, this might be due to extraneous substances rather than papain (11). Some evidence also suggests that high doses of papaya seed extract have abortifacient activity and can adversely affect fetal development (67870). Theoretically, eating large amounts of papaya seeds may have similar effects.
LACTATION: LIKELY SAFE
when the ripe fruit is consumed in amounts commonly found in foods.
There is insufficient reliable information available about the safety of using papaya medicinally; avoid using.
POSSIBLY SAFE ...when used orally and appropriately (4,12,272,512,1740).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Slippery elm bark has historically been inserted into the cervix to induce abortion. As a result, slippery elm has been reported in some sources to have abortifacient activity. However, there is no reliable information available about whether slippery elm has abortifacient activity when taken orally.
Below is general information about the interactions of the known ingredients contained in the product Acai Berry. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, taking acai with antidiabetes drugs might interfere with glycemic control.

|
Theoretically, aloe gel might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
Details
In vitro research shows that aloe gel can inhibit platelet aggregation. This inhibition was greater than that seen with celecoxib, but less than that seen with aspirin (105501).
|
Aloe might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, aloe might decrease the levels and clinical effects of CYP1A2 substrates.
Details
In vitro research shows that aloe extract induces CYP1A2 enzymes (111404).
|
Theoretically, aloe latex might increase the risk of adverse effects when taken with cardiac glycosides.
Details
Overuse of aloe latex can increase the risk of adverse effects from cardiac glycoside drugs, such as digoxin, due to potassium depletion. Overuse of aloe, along with cardiac glycoside drugs, can increase the risk of toxicity (19).
|
Theoretically, aloe latex might increase the risk of hypokalemia when taken with diuretic drugs.
Details
Overuse of aloe latex might compound diuretic-induced potassium loss, increasing the risk of hypokalemia (19).
|
Theoretically, aloe latex might increase the risk for fluid and electrolyte loss when taken with stimulant laxatives.
Details
|
Theoretically, aloe latex might increase the risk of bleeding when taken with warfarin.
Details
Aloe latex has stimulant laxative effects. In some people aloe latex can cause diarrhea. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Advise patients who take warfarin not to take excessive amounts of aloe vera.
|
Theoretically, chlorella might have additive effects with photosensitizing drugs.
Details
Chlorella has been reported to cause photosensitization (3900,5852). In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.
|
Theoretically, chlorella might reduce the clinical effects of warfarin.
Details
|
Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Details
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation (7622,12634,20321,20322,20323,96257). However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials (96257). Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
|
Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Details
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects (12633). Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone (107901).
|
Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
Details
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time (20401).
|
Theoretically, ginger might increase the levels of CYP1A2 substrates.
Details
In vitro research shows that ginger inhibits CYP1A2 activity (111544). However, this interaction has not been reported in humans.
|
Theoretically, ginger might increase the levels of CYP2B6 substrates.
Details
In vitro research shows that ginger inhibits CYP2B6 activity (111544). However, this interaction has not been reported in humans.
|
Theoretically, ginger might increase the levels of CYP2C9 substrates.
Details
In vitro research shows that ginger inhibits CYP2C9 activity (111544). However, this interaction has not been reported in humans.
|
Ginger might increase or decrease the levels of CYP3A4 substrates.
Details
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity (111544,111644). Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration (111644).
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates (111404). However, this interaction has not been reported in humans. |
Theoretically, ginger might increase levels of losartan and the risk of hypotension.
Details
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan (102459). It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.
|
Theoretically, ginger might increase levels of metronidazole.
Details
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced (20350).
|
Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Details
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone (20324).
|
Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
Details
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates (111544,111644). Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration (111644).
|
Ginger might increase the risk of bleeding with phenprocoumon.
Details
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea (12880).
|
Ginger might increase the risk of bleeding with warfarin.
Details
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation (7622,12634,20321,20322,20323). In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin (12880). In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen (20349). A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months (20348). However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin (12881,15176). Until more is known, monitor INRs closely in patients taking large amounts of ginger.
|
Theoretically, inulin might increase the risk of hypoglycemia with antidiabetes drugs.
Details
|
Theoretically, taking lycopene with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
Details
|
Theoretically, papaya extract may increase the levels and clinical effects of amiodarone.
Details
Animal research in rats shows that a single oral dose of papaya extract, as well as multiple doses of papaya extract daily over 14 days, prior to a single dose of amiodarone delays the time to maximum amiodarone concentration. However, only the 14-day papaya extract regimen increases systemic amiodarone exposure by 60% to 70% (93093). This interaction has not been reported in humans.
|
Concomitant use of antidiabetic drugs with fermented papaya can produce additive effects. It is unclear if other forms of papaya have the same effect.
Details
A small low-quality clinical study in patients with type 2 diabetes who are taking glibenclamide shows that taking a fermented papaya preparation 3 grams daily for 2 months decreases fasting and postprandial blood glucose levels when compared to baseline. Additionally, of the 25 patients in the study, 9 required a reduction in glibenclamide dose (67902).
|
Theoretically, consuming large quantities of papaya fruit can reduce the clinical effects of levothyroxine.
Details
In one case-report, a 37-year-old male with a history of thyroidectomy who was stabilized on levothyroxine for 5 years presented with hypothyroidism after consuming 5-6 papaya fruits daily for 14 days during vacation. In a controlled re-challenge test involving 5-6 papayas daily, the patient remained euthyroid for 7 days, but developed mild hypothyroidism after 14 days. Both times, thyroid levels normalized 40-45 days after discontinuing papaya (93087).
|
Theoretically, concomitant use of warfarin with papain-containing papaya extract might increase the effects and side effects of warfarin.
Details
In one case report, a patient previously stable on warfarin was found to have an international normalization ratio (INR) of 7.4, which was attributed to ingestion of a supplement containing papain from papaya extract (613).
|
Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Details
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs (19).

Below is general information about the adverse effects of the known ingredients contained in the product Acai Berry. 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, acai seems to be well tolerated.
Other ...Raw acai fruit and juice can be contaminated with a parasitic protozoan called Trypanosoma cruzi, which causes American trypanosomiasis or Chagas Disease. A Brazilian outbreak of this disease in 2006 was linked to consumption of acai juice (17194,30245).
General
...Orally and topically, aloe products are generally well tolerated when used in typical doses.
However, oral aloe latex is associated with a greater risk of adverse effects, especially when used in high doses or long-term.
Most Common Adverse Effects:
Orally: Aloe latex may cause abdominal pain, cramps, and diarrhea.
Topically: Burning, erythema, and itching. Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Aloe latex is associated with serious adverse effects when taken in high doses or long-term. Cases of acute hepatitis due to a hypersensitivity reaction to aloe leaf extract has been reported.
Dermatologic ...Topically, aloe gel has occasionally been associated with burning (12164,19741,30697,30706), itching (12164,19741,30697), eczema (90122), erythema (19748,30706,90123), contact dermatitis (12163,12164,30695,30736,30737,30738,30740), popular eruption (30732), and urticaria (30712). Also, a case of generalized nummular and popular dermatitis attributed to hypersensitivity has been reported for a 47-year-old male who used aloe leaf gel, both topically and orally, for 4 years (30740).
Endocrine ...A case of severe hypokalemia has been reported for a male breast cancer patient who was undergoing chemotherapy and using aloe vera 1 liter daily orally for 2 weeks. The hypokalemia was attributed to the cathartic effects of aloe and resolved once aloe use was discontinued (30704).
Gastrointestinal
...Orally, aloe latex can cause abdominal pain and cramps.
Long-term use or abuse of aloe latex can cause diarrhea, sometimes with hypokalemia, albuminuria, hematuria, muscle weakness, weight loss, arrhythmia, and pseudomelanosis coli (pigment spots in intestinal mucosa). Pseudomelanosis coli is believed to be harmless, and usually reverses with discontinuation of aloe. It is not directly associated with an increased risk of developing colorectal adenoma or carcinoma (6138). Orally, aloe gel may cause nausea, stomach cramps, and other gastrointestinal complaints in some patients (104174,111921,111663).
Topically, applying aloe gel in the mouth may cause nausea within 5 minutes of application in some patients (90124).
Hematologic ...A case of Henoch-Schonlein purpura, characterized by abdominal pain, purpura, and severe arthralgia, has been reported in a 52-year-old male who drank aloe juice prepared from four to five leaflets for 10 days prior to symptom development (91598).
Hepatic ...Cases of acute hepatitis have been reported after ingestion of aloe leaf extracts for between 3 weeks and 5 years. This is thought to be a hypersensitivity reaction (15567,15569,16386,17419,90126,91598). A case of acute hepatitis has also been reported for a 45-year-old female who drank two ounces of Euforia juice (Nuverus International), a product containing green tea, noni, goji, and aloe, daily for one month (90125). However, one small clinical trial in healthy individuals shows that taking aloe gel 2 ounces twice daily for 60 days does not impair liver function (104174).
Renal ...Orally, aloe latex can cause hemorrhagic gastritis, nephritis, and acute kidney failure following prolonged use of high doses (1 gram daily or more) (8961).
General
...Orally, black walnut fruit (nut) is well tolerated.
However, the leaf, bark, and hull of black walnut contain high quantities of tannins, which may cause adverse effects when used orally or topically.
Most Common Adverse Effects:
Orally: The leaf, bark, and hull can cause gastrointestinal upset.
Topically: Hull preparations may cause a temporary yellow or brown discoloration at the site of application. The leaf, bark, and hull can cause skin irritation.
Serious Adverse Effects (Rare):
Orally: The bark may increase the risk for tongue cancer or lip leukoplakia when used long-term.
All routes of administration: Allergic reactions, including anaphylaxis.
Dermatologic ...Topically, black walnut leaf, bark, or hull may have an irritating effect on the skin due to tannin content. Black walnut hull preparations might cause a temporary yellow or brown discoloration of the skin at the site of application (12).
Gastrointestinal ...Orally, black walnut leaf, bark, or hull may cause gastrointestinal upset due to tannin content (12). Also, daily use of the juglone-containing bark of a related species (English walnut) is associated with increased risk of tongue cancer and lip leukoplakia (2,12).
Hepatic ...Orally, black walnut leaf, bark, or hull may cause liver damage if taken for extended periods of time due to tannin content (12).
Immunologic ...Tree nuts, which include black walnuts, can cause allergic reactions in sensitive individuals. Due to the prevalence of this allergy in the general population, tree nuts are classified as a major food allergen in the United States (105410).
Renal ...Orally, black walnut leaf, bark, or hull may cause kidney damage if taken for extended periods of time due to tannin content (12).
General
...Orally, chlorella is generally well-tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, flatus, nausea, photosensitivity, and stool discoloration.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...Orally, photosensitivity reactions have occurred following ingestion of chlorella (3900,5852). According to case reports, five patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). The photosensitizing agent in the chlorella tablets was identified as pheophorbide-a and its ester.
Gastrointestinal
...Orally, chlorella can cause diarrhea, abdominal cramping, flatus, and nausea, especially during the first two weeks of treatment (5890,6804,92130,92132).
In one clinical trial, one out of 42 patients reported nausea and one reported diarrhea (92132). In another trial, taking chlorella tablets (Sun Chlorella A, Sun Chlorella Corp) and a chlorella extract (Wakasa Gold, Sun Chlorella Corp) resulted in transient worsening of constipation in 4 of 13 patients and transient mild diarrhea in 2 of 13 patients (92130).
Green discoloration of the feces has also been reported, due to the chlorophyll content of chlorella (6804,95013).
Hematologic ...Orally, chlorella has been linked to one case of thrombocytopenia; however, causality has not been determined. A 49-year-old female living in Turkey presented with thrombocytopenia (a platelet count of 27,000/mm3) after taking chlorella 1080 mg daily for 20 days. Platelet counts had been normal one month earlier, and returned to normal two weeks after discontinuing the chlorella supplement (99879).
Immunologic ...Allergic reactions, including asthma and anaphylaxis, have been reported in people taking chlorella and in those preparing chlorella tablets (3900,5847,41827,105645).
Neurologic/CNS
...Orally, manganese (Mn)-induced parkinsonism has been reported after long-term consumption of chlorella extract.
In this case, a patient on maintenance hemodialysis reported gait disturbance, dysarthria, elevated serum and cerebrospinal fluid manganese levels, and abnormal magnetic resonance imaging (MRI) findings of the brain. The authors identified the condition as a rare case of Mn-induced parkinsonism, which may have been due to long-term ingestion of a chlorella extract containing 1.7 mg of Mn in the usual daily dose. The patient underwent edetic acid infusion therapy, which improved the MRI abnormalities and the other symptoms improved four months later (41817).
In one study, fatigue was reported in 18 of 41 patients receiving chlorella 200 mg (10388).
General
...Orally, ginger is generally well tolerated.
However, higher doses of 5 grams per day increase the risk of side effects and reduce tolerability. Topically, ginger seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal discomfort, burping, diarrhea, heartburn, and a pepper-like irritant effect in the mouth and throat. However, some of these mild symptoms may be reduced by ingesting encapsulated ginger in place of powdered ginger.
Topically: Dermatitis in sensitive individuals.
Cardiovascular ...Orally, use of ginger resulted in mild arrhythmia in one patient in a clinical trial (16306).
Dermatologic
...Orally, ginger can cause hives (17933), as well as bruising and flushing (20316) or rash (20316).
Topically, ginger can cause dermatitis in sensitive individuals (12635,46902).
Gastrointestinal
...Orally, common side effects of ginger include nausea (17933,22602,89898,101761), belching (10380,103359), dry mouth (103359), dry retching (10380), vomiting (10380), burning sensation (10380), oral numbness (22602), abdominal discomfort (5343,89898,96253), heartburn (5343,7624,12472,16306,20316,51845,89894,89895,89898,89899)(101760,101761,101762,111543), diarrhea (5343,101760), constipation (89898,101760,101761), or a transient burning or "chilly hot" sensation of the tongue and throat (52076).
Orally, Number Ten, a specific product composed of rhubarb, ginger, astragalus, red sage, and turmeric, can increase the incidence of loose stools (20346).
Four cases of small bowel obstruction due to ginger bolus have been reported following the ingestion of raw ginger without sufficient mastication (chewing). In each case, the bolus was removed by enterotomy. Ginger is composed of cellulose and therefore is resistant to digestion. It can absorb water, which may cause it to swell and become lodged in narrow areas of the digestive tract (52115).
Genitourinary ...In one clinical trial, some patients reported increased menstrual bleeding while taking a specific ginger extract (Zintoma, Goldaru) 250 mg four times daily orally for 3 days (17931). An "intense" urge to urinate after 30 minutes was reported in two of eight patients given 0.5-1 gram of ginger (7624). However, this effect has not been corroborated elsewhere. Dysuria, flank pain, perineal pain, and urinary stream interruption have been reported in a 43-year-old male who drank ginger tea, containing 2-3 teaspoons of dry ginger, daily over 15 years. The adverse effects persisted for 4 years and were not associated with increases in urinary frequency or urgency. Upon discontinuing ginger, the patient's symptoms began to improve within one week and completely resolved after eight weeks, with no relapses six months later (107902).
Immunologic ...In one case report, a 59-year-old Japanese female with multiple allergic sensitivities developed pruritus and then anaphylactic shock after taking an oral ginger-containing herbal supplement for motion sickness (Keimei Gashinsan, Keimeido). The patient had used this supplement previously for over 20 years with no allergic reaction. The authors theorized the development of a cross-reactivity to ginger after the use of an oral supplement containing zedoary and turmeric, which are also in the Zingiberaceae family (102463).
Neurologic/CNS ...Orally, ginger may cause sedation, drowsiness, or dizziness (16306,17933,51845).
General ...No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted. There is some concern that hyssop oil has demonstrated toxicity at very low doses when administered orally in animal studies (1304).
General
...Orally, inulin is well tolerated.
Most Common Adverse Effects:
Orally: Bloating, constipation, diarrhea, flatulence, and gastrointestinal cramps.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis has occurred following consumption of foods high in inulin.
Gastrointestinal ...Orally, inulin may cause flatulence, bloating, diarrhea, constipation, and gastrointestinal cramps, especially at doses over 30 grams (7604,8450,8509,93716,93721,93724,96836,96850,96851,99843)(107936,107940,107941,110602).
Immunologic ...Severe allergic reactions to inulin-containing foods have been reported. There is one report of anaphylaxis following consumption of foods with a high concentration of inulin including salsify, artichoke leaves, and margarine (7608).
General
...Orally, lycopene is generally well tolerated.
Most Common Adverse Effects:
Orally: Mild gastrointestinal complaints, skin rash.
Cardiovascular ...A case of chest pain has been reported in a pregnant patient who was taking a specific lycopene product (LycoRed, Jagsonpal Pharmaceuticals) 2 mg daily (60428). The role of lycopene in this event has not been determined.
Dermatologic
...Orally, lycopene supplements have been reported to cause allergic skin reactions in some clinical studies (60409,60417).
Skin rash also occurred in a pregnant patient who was taking a specific lycopene product (LycoRed, Jagsonpal Pharmaceuticals) (60428).
There is at least one case report of carotenoderma, with a yellow-orange coloration in the stratum corneum of the skin, in a 26-year-old female who consumed 20-30 cherry tomatoes and 180 mL tomato juice, as well as other carotenoid-rich foods, daily for up to 10 years. Plasma levels of carotenoids, mainly lycopene, were elevated (109774).
Gastrointestinal ...Orally, gastrointestinal side effects associated with use of lycopene supplements include diarrhea, flatulence, abdominal distension, nausea, vomiting, dyspepsia, and anorexia (60372,60384,60417,60433,60464).
General
...Orally, papaya fruit is well tolerated when consumed in food amounts.
Papaya leaf extract seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Nausea and vomiting from papaya leaf extract.
Topically: Burning sensation from unripe papaya.
Serious Adverse Effects (Rare):
Orally: Severe allergic reactions.
Dermatologic
...Orally, high doses of papaya might cause yellow skin discoloration.
A case of carotenemia has been reported for a 42-year-old female who consumed 1.5-2 papayas daily for 6 months. The condition resolved when she stopped eating papayas (67929).
Topically, unripe papaya fruit may cause occasional burning sensation when applied to skin ulcers (67856).
Gastrointestinal ...Orally, the leaf extract has been reported to cause nausea and vomiting in clinical research (102799). A case of esophageal perforation has been reported for a previously healthy 27-year-old female who used papain, a constituent of papaya latex, to digest a piece of meat stuck in her esophagus (93083).
Immunologic ...Orally, papain, a constituent of raw, unripe papaya, has been reported to cause allergic reactions in sensitive individuals, including itchy watery eyes, runny nose, sneezing, abdominal cramps, sweating, and diarrhea (6,967). Papaya may also cause hypersensitivity reactions such as systemic contact dermatitis, which occur more commonly in people who are allergic to latex (6197,7853,57635). A case of systemic contact dermatitis has been reported for a 55-year-old female with no prior history of atopic disease or drug allergy after ingesting a throat lozenge containing papaya juice (67942).
Other ...In regions with arsenic-contaminated soil, papaya fruits contain a higher mean concentration of arsenic compared with many other forms of vegetation grown in the regions. Eating papaya from these regions is thought to contribute to higher dietary levels of arsenic (32461,67879).
General ...Orally, slippery elm seems to be well tolerated. A thorough evaluation of safety outcomes with topical use of slippery elm has not been conducted.
Dermatologic ...Topically, slippery elm extracts can cause contact dermatitis. The pollen is an allergen (6). Contact dermatitis and urticaria have been reported after exposure to slippery elm or an oleoresin contained in the slippery elm bark (75131).
