Dried gotu kola has been used with apparent safety in doses of up to 2200 mg daily for 4 weeks (6887,11062,11063,11064,11065,11066,11067,11068,11069,11070)(11071,99756,99757,99758,105329,105332,105333). A specific gotu kola extract (Centellicum, Horphag Research Ltd) 450-675 mg daily has been used with apparent safety for up to 6 weeks (99756,99757).
PREGNANCY: POSSIBLY SAFE
when used topically and appropriately (11073,13559).
There is insufficient reliable information available about the safety gotu kola when used orally during pregnancy; avoid using.
LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally, short-term. Holy basil leaf extract has been used with apparent safety at a dose of 500 mg daily for 60-90 days (12242,18107,19575,91571,96944). ...when used topically in the mouth, short-term. Holy basil has been used with apparent safety as a 4% mouthwash solution for up to 30 days (91570,103621).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used in high doses during pregnancy or when trying to conceive.
Animal research suggests that relatively high doses of holy basil extract (200 mg/kg) may reduce implantation rate when used for one week, while long-term use of higher doses (2-4 grams/kg) may decrease the number of full-term pregnancies (55040,91569). There is insufficient reliable information available regarding the safety of holy basil during lactation; avoid using.
LIKELY SAFE ...when used orally in amounts commonly used in foods. Red clover has Generally Recognized As Safe (GRAS) status for use in foods in the US (4912,10372).
POSSIBLY SAFE ...when used orally and appropriately in supplemental amounts. Red clover extracts containing up to 80 mg isoflavones have been used with apparent safety in clinical studies lasting up to 2 years (3375,6127,8925,11089,11091,17091,19540,19556,91524,102901,102840). ...when used topically and appropriately. Red clover extracts have been used topically with apparent safety for up to 4 weeks (102839).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (4912).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in medicinal amounts.
Red clover has estrogenic activity (19555); avoid using. There is insufficient reliable information available about the safety of the topical use of red clover during pregnancy and lactation.
LIKELY SAFE ...when used orally in amounts commonly found in foods. White sandalwood oil has Generally Recognized As Safe (GRAS) status for use in foods in the US (4912).
POSSIBLY UNSAFE ...when used orally for longer than 6 weeks. Use for more than 6 weeks is associated with kidney damage (12,19). There is insufficient reliable information available about the safety of white sandalwood when inhaled or when used topically in amounts greater than those found in cosmetics.
PREGNANCY: LIKELY UNSAFE
when used orally in medicinal amounts; sandalwood is reported to have abortifacient effects (19); avoid using.
LACTATION:
Insufficient reliable information available; avoid using amounts greater than those found in foods.
LIKELY SAFE ...when used orally and appropriately. Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 40 mg daily (7135). ...when used topically and appropriately (2688,6538,6539,7135,8623,11051,111291).
POSSIBLY SAFE ...when used orally and appropriately in doses higher than the tolerable upper intake level (UL). Because the UL of zinc is based on regular daily intake, short-term excursions above 40 mg daily are not likely to be harmful. In fact, there is some evidence that doses of elemental zinc as high as 80 mg daily in combination with copper 2 mg can be used safely for approximately 6 years without significant adverse effects (7303,8622,92212). However, there is some concern that doses higher than the UL of 40 mg daily might decrease copper absorption and result in anemia (7135).
POSSIBLY UNSAFE ...when used intranasally. Case reports and animal research suggest that intranasal zinc might cause permanent anosmia or loss of sense of smell (11155,11156,11703,11704,11705,11706,11707,16800,16801,17083). Several hundred reports of anosmia have been submitted to the US Food and Drug Administration (FDA) and the manufacturer of some intranasal zinc products (Zicam) (16800,16801). Advise patients not to use intranasal zinc products.
LIKELY UNSAFE ...when taken orally in excessive amounts. Ingestion of 10-30 grams of zinc sulfate can be lethal in adults (7135). Chronic intake of 450-1600 mg daily can cause multiple forms of anemia, copper deficiency, and myeloneuropathies (7135,17092,17093,112473). This has been reported with use of zinc-containing denture adhesives in amounts exceeding the labeled directions, such as several times a day for several years (17092,17093). Advise patients to follow the label directions on denture adhesives that contain zinc.
CHILDREN: LIKELY SAFE
when used orally and appropriately (7135).
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL). The UL for children is based on age: 4 mg daily for 0-6 months, 5 mg daily for 7-12 months, 7 mg daily for 1-3 years, 12 mg daily for 4-8 years, 23 mg daily for 9-13 years, and 34 mg daily for 14-18 years (7135,97140).
CHILDREN: POSSIBLY UNSAFE
when used orally in high doses.
Taking amounts greater than the UL can cause sideroblastic anemia and copper deficiency (7135). ...when used topically on damaged skin. An infant treated with 10% zinc oxide ointment for severe diaper rash with perianal erosions developed hyperzincemia. Absorption seemed to occur mainly via the erosions; plasma levels dropped after the erosions healed despite continued use of the ointment (106905).
PREGNANCY: LIKELY SAFE
when used orally and appropriately.
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 34 mg daily during pregnancy in those 14-18 years of age and 40 mg daily in those 19-50 years of age (7135).
PREGNANCY: LIKELY UNSAFE
when used orally in doses exceeding the UL (7135).
LACTATION: LIKELY SAFE
when used orally and appropriately.
Zinc is safe in amounts that do not exceed the tolerable upper intake level (UL) of 34 mg daily during lactation in those 14-18 years of age, and 40 mg daily for those 19-50 years of age (7135).
LACTATION: POSSIBLY UNSAFE
when used orally in doses exceeding the UL.
Higher doses can cause zinc-induced copper deficiency in nursing infants (7135).
Below is general information about the interactions of the known ingredients contained in the product Derma Claris. 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 copper with contraceptive drugs might increase the levels and toxic effects of copper.
 Details
A meta-analysis of clinical studies suggests that chronic use of oral contraceptives increases serum copper levels by a mean of 57 mcg/dL. In most people, this resulted in levels above the normal reference range for copper (92395).
|
Theoretically, taking copper with penicillamine might decrease the absorption of penicillamine; separate dosing by at least 2 hours.
Details
|
Theoretically, taking dandelion root along with anticoagulant or antiplatelet drugs might increase the risk of bruising and bleeding.
Details
In vitro research suggests that dandelion root inhibits platelet aggregation (18291).
|
Theoretically, dandelion might increase the risk for hypoglycemia when used with antidiabetes drugs.
Details
Laboratory research suggests that dandelion extract may have moderate alpha-glucosidase inhibitor activity and might also increase insulin secretion (13474,90926). Also, in a case report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemia 2 weeks after beginning to eat salads containing dandelion (46960).
|
Theoretically, dandelion might increase levels of drugs metabolized by CYP1A2.
Details
Laboratory research suggests that dandelion might inhibit CYP1A2 (12734). So far, this interaction has not been reported in humans. However, until more is known, watch for an increase in the levels of drugs metabolized by CYP1A2 in patients taking dandelion.
|
Theoretically, dandelion might increase the clearance of drugs that are UDP-glucuronosyltransferase substrates.
Details
There is some preliminary evidence that dandelion might induce UDP-glucuronosyltransferase, a phase II enzyme (12734).
|
Theoretically, through diuretic effects, dandelion might reduce excretion and increase levels of lithium.
Details
Animal research suggests that dandelion has diuretic properties (13475). As diuretics can increase serum lithium levels, the dose of lithium might need to be decreased when taken with dandelion.
|
Theoretically, dandelion might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Details
Dandelion contains significant amounts of potassium (13465).
|
Theoretically, dandelion might lower fluoroquinolone levels.
Details
Animal research shows that dandelion reduces absorption of ciprofloxacin and can lower levels by 73% (13477). However, this effect has not been reported in humans.
|
Theoretically, taking gotu kola might increase the sedative effects of CNS depressants.
Details
|
Theoretically, taking gotu kola with hepatotoxic drugs might have additive adverse effects.
Details
|
Theoretically, holy basil seed oil might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Details
Animal research shows that holy basil seed oil can prolong bleeding time, possibly due to inhibition of platelet aggregation (13251). However, it is not known if this occurs in humans.
|
Theoretically, holy basil might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, holy basil seed oil might increase the sedative effects of pentobarbital.
Details
|
Although some laboratory research suggests that red clover may have anticoagulant and antiplatelet activity, clinical research has not shown this effect.
Details
In vitro research suggests that genistein in red clover has antiplatelet effects, and historically, red clover was thought to have anticoagulant effects due to its coumarin content. However, some experts state that this is unlikely as most natural coumarins have not been shown to have anticoagulant effects, and their content in red clover is low (17091,19557,19558,19559). Additionally, some clinical research in postmenopausal patients found no effect on coagulation or prothrombin time with the use of red clover flowering tops 378 mg daily for 12 months or red clover isoflavone (Rimostil) 50 mg daily for 2 years (17091,91524).
|
Theoretically, soy might reduce the clearance of caffeine; however, a small clinical study found no effect.
Details
Red clover contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females (23582). However, this effect does not seem to occur with the lower amounts of genistein found in red clover. A clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP1A2; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover inhibits CYP1A2 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of caffeine, a CYP1A2 probe substrate (105693).
|
Theoretically, red clover might increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
In vitro evidence suggests that red clover weakly inhibits CYP2C19 (12479). This interaction has not been reported in humans.
|
Theoretically, red clover might increase levels of drugs metabolized by CYP2C9; however, a small clinical study found no effect.
Details
In vitro evidence suggests that red clover might inhibit CYP2C9 (12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of tolbutamide, a CYP2C9 probe substrate (105693).
|
Theoretically, red clover might increase levels of drugs metabolized by CYP3A4; however, a small clinical study found no effect.
Details
In vitro evidence shows that red clover might inhibit CYP3A4 isoenzymes (6450,12479). However, a clinical study in healthy postmenopausal individuals shows that taking red clover capsules standardized to contain 60 mg isoflavones twice daily for 14 days does not affect the pharmacokinetics of alprazolam, a CYP3A4 probe substrate (105693).
|
Theoretically, concomitant use of large amounts of red clover might interfere with estrogen therapy.
Details
|
Theoretically, red clover might increase the risk of methotrexate toxicity.
Details
In a case report, a 52-year-old female receiving weekly methotrexate injections for psoriasis developed symptoms of methotrexate toxicity, including severe vomiting and epigastric pain, after three days of taking red clover 430 mg daily. Toxicity resolved after red clover was discontinued. However, no liver function tests or methotrexate levels were reported (91522).
|
Theoretically, the phytoestrogens in red clover might interfere with tamoxifen.
Details
In vitro and animal research suggests that genistein, a constituent of red clover, might antagonize the antitumor effects of tamoxifen (8192). However, there is some evidence from an animal study that red clover does not reduce the efficacy of tamoxifen (102901). Until more is known, tell patients taking tamoxifen to avoid red clover.
|
Theoretically, taking white sandalwood might reduce lithium excretion and increase serum levels of lithium.
Details
White sandalwood is thought to have diuretic properties, which may reduce lithium excretion. The dose of lithium might need to be decreased.
|
Amiloride can modestly reduce zinc excretion and increase zinc levels.
Details
Clinical research shows that amiloride can reduce urinary zinc excretion, especially at doses of 10 mg per day or more. This zinc-sparing effect can help to counteract zinc losses caused by thiazide diuretics, but it is unlikely to cause zinc toxicity at usual amiloride doses (830,11626,11627,11634). The other potassium-sparing diuretics, spironolactone (Aldactone) and triamterene (Dyrenium), do not seem to have a zinc-sparing effect.
|
Zinc modestly reduces levels of atazanavir, although this effect does not seem to be clinically significant.
Details
Clinical research shows that zinc might decrease serum atazanavir levels by chelating with atazanavir in the gut and preventing its absorption (93578). Although a single dose of zinc sulfate (Solvazinc tablets) 125 mg orally does not affect atazanavir concentrations in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate 125 mg daily for 2 weeks reduces plasma levels of atazanavir by about 22% in these patients. However, despite this decrease, atazanavir levels still remain at high enough concentrations for the prevention of HIV virus replication (90216).
|
Zinc might decrease cephalexin levels by chelating with cephalexin in the gut and preventing its absorption.
Details
A pharmacokinetic study shows that zinc sulfate 250 mg taken concomitantly with cephalexin 500 mg decreases peak levels of cephalexin by 31% and reduces the exposure to cephalexin by 27%. Also, taking zinc sulfate 3 hours before cephalexin decreases peak levels of cephalexin by 11% and reduces the exposure to cephalexin by 18%. By decreasing cephalexin levels, zinc might increase the risk of treatment failure. This effect does not occur when zinc is taken 3 hours after the cephalexin dose (94163). To avoid an interaction, advise patients take zinc sulfate 3 hours after taking cephalexin.
|
Theoretically, zinc might interfere with the therapeutic effects of cisplatin.
Details
Animal research suggests that zinc stimulates tumor cell production of the protein metallothionein, which binds and inactivates cisplatin (11624,11625). It is not known whether zinc supplements or high dietary zinc intake can cause clinically significant interference with cisplatin therapy. Cisplatin might also increase zinc excretion.
|
Theoretically, taking zinc along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Details
|
Zinc might reduce the levels and clinical effects of penicillamine.
Details
By forming an insoluble complex with penicillamine, zinc interferes with penicillamine absorption and activity. Zinc supplements reduce the efficacy of low-dose penicillamine (0.5-1 gram/day), but do not seem to affect higher doses (1-2.75 gram/day), provided dosing times are separated (2678,4534,11605). Advise patients to take zinc and penicillamine at least 2 hours apart.
|
Zinc can decrease the levels and clinical effects of quinolones antibiotics.
Details
|
Zinc modestly reduces levels of ritonavir.
Details
Clinical research shows that zinc might reduce serum ritonavir levels by chelating with ritonavir in the gut and preventing its absorption (93578). In patients with HIV, ritonavir is taken with atazanavir to prevent the metabolism and increase the effects of atazanavir. A pharmacokinetic study shows that, in patients being treated with atazanavir/ritonavir, co-administration of zinc sulfate (Solvazinc tablets) 125 mg as a single dose or as multiple daily doses for 2 weeks reduces plasma levels of ritonavir by about 16% (90216). However, atazanavir levels still remains high enough to prevent HIV virus replication. Therefore, the decrease in ritonavir levels is not likely to be clinically significant.
|
Zinc might reduce levels of tetracycline antibiotics.
Details
Tetracyclines form complexes with zinc in the gastrointestinal tract, which can reduce absorption of both the tetracycline and zinc when taken at the same time (3046,4945). Taking zinc sulfate 200 mg with tetracycline reduces absorption of the antibiotic by 30% to 40% (11615). Demeclocycline and minocycline cause a similar interaction (4945). However, doxycycline does not seem to interact significantly with zinc (11615). Advise patients to take tetracyclines at least 2 hours before, or 4-6 hours after, zinc supplements to avoid any interactions.

Below is general information about the adverse effects of the known ingredients contained in the product Derma Claris. 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, copper is generally well tolerated when consumed in doses below the tolerable upper intake level (UL).
Dermatologic
...Contact dermatitis caused by copper has been reported rarely.
A case report describes a 5-year-old male who developed recurrent fingertip dermatitis and a positive skin test to copper after playing with toy cars made with a copper-containing alloy (95538). Also, in a small clinical trial in children 1-3 months of age with umbilical granuloma, 3 of 33 children receiving a single topical application of copper sulfate developed superficial burns, whereas no superficial burns occurred in those receiving topical sodium chloride (109403).
In one case report, a 68-year-old male with type 2 diabetes and peripheral neuropathy developed second- and third-degree burns after wearing a copper-containing compression sock on the right leg for 3 hours while sitting in the sun. The patient received treatment with topical silver sulfadiazine and oral clindamycin. After 6 weeks, the patient was found to have multiple persistent wounds containing necrotic tissue which required debridement, daily dressing changes, and tubular compression. It is thought that the heat conductance of copper magnified the effects of sun exposure in this case (109402).
Endocrine ...There is evidence from observational studies that people with diabetes (type 1 or type 2) have higher copper levels in their blood than people without diabetes, although not all studies have shown this (95537). It is not known if elevated copper levels contribute to development or worsening of diabetes.
Hematologic ...A case report of copper overdose in a 28-year-old male resulted in hemolysis exacerbated by glucose-6-phosphate dehydrogenase deficiency. The patient was hospitalized, received D-penicillamine chelation, blood transfusion, and ultimately, 4 cycles of plasmapheresis which led to clinical recovery (112378).
General
...Orally, dandelion seems to be well tolerated.
Most Common Adverse Effects:
Orally: Diarrhea, heartburn, and stomach discomfort.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Cardiovascular ...In one report, a 39-year-old obese woman developed palpitations and syncope after taking a weight loss supplement containing a combination of dandelion, bladderwrack, and boldo for 3 weeks. The patient was found to have prolonged QT-interval on ECG and frequent episodes of sustained polymorphic ventricular tachycardia (14321). It is not clear whether dandelion, another ingredient, or the combination of ingredients is responsible for this adverse effect. The product was not analyzed to determine the presence of any potential toxic contaminants.
Dermatologic ...Topically, dandelion can cause contact dermatitis and erythema multiforme in sensitive individuals. Dandelion can cause an allergic reaction in individuals sensitive to the Asteraceae/Compositae family (13478,13481,42893,46945,46977). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Endocrine ...In one report, a 56-year-old man with renal impairment developed hyperoxalaemia and peripheral gangrene after ingesting large amounts of dandelion tea (10 to 15 cups daily for 6 months). The adverse effect was attributed to the high oxalate content of dandelion tea (258 mcmol/L) and reduced renal oxalate clearance caused by renal impairment (90639). In another report, a 58-year-old woman with type 2 diabetes who was being treated with insulin developed hypoglycemic symptoms 2 weeks after beginning to eat salads containing dandelion (46960). The hypoglycemic effect was attributed to the potential alpha-glucosidase inhibitory activity of dandelion.
Gastrointestinal ...Gastrointestinal symptoms, including stomach discomfort, diarrhea, and heartburn, have been reported following oral use of dandelion (19146,36931). A case of intestinal blockage has been reported for a patient who ingested a large amount of dandelion greens three weeks after undergoing a stomach operation (46981). Also, a case of hemorrhagic cystitis has been reported for a 33-year-old woman who took a specific herbal product (Slim-Kombu, Balestra and Mech, Vicenza, Italy) containing 20 herbal extracts, including dandelion extract. Symptoms resolved after the patient discontinued using the product, and symptoms resumed when the patient began taking the supplement again four months later. While various ingredients in the supplement may have contributed to the symptoms, it is possible that dandelion extract may have contributed to the effect due to its diuretic, laxative, cholagogue, and antirheumatic properties (46959).
Other ...Orally, products containing dandelion pollen can cause allergic reactions, including anaphylaxis (13479,13480). Also, rhinoconjunctivitis and asthma have been reported after handling products such as bird feed containing dandelion and other herbs, with reported positive skin tests for dandelion hypersensitivity (46948). Dandelion pollen may cause pollinosis, such as allergic rhinitis and conjunctivitis (18065,46951,46964,46966,46972).
General
...Orally and topically, gotu kola seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastric irritation and nausea.
Topically: Eczema.
Serious Adverse Effects (Rare):
Orally: Hepatotoxicity.
Dermatologic ...Topically, gotu kola may cause eczema (10277,10278). Also, gotu kola can cause allergic contact dermatitis, characterized by erythema, itching, papules, and a burning sensation (4,6887,9789,52875,52887,52896,52902). One specific gotu kola product (Blasteostimulina,Almirall, S. A.) has been reported to cause allergic contact dermatitis. However, not all patients with reactions to this product are sensitive to gotu kola; some patients are sensitive to neomycin, another ingredient in the product (52875). Madecassol ointment (Rona Laboratories Limited) is another gotu kola product that has resulted in allergic contact dermatitis. Controlled testing suggests that this product can cause this adverse effect in about 8% of patients (9789). Centellase cream has also caused allergic contact dermatitis in at least two cases (52887,52888).
Gastrointestinal ...In some patients, gotu kola can extract cause gastrointestinal upset and nausea (780,6887,52894).
Hepatic
...There is concern that gotu kola may cause liver toxicity in some patients.
There are at least four case reports of hepatotoxicity associated with gotu kola; however, hepatotoxic contaminants cannot be ruled out, as laboratory analysis was not conducted on the products used. Additionally, the doses of gotu kola used in these cases were not reported (13182,92506). In a clinical trial where liver function was monitored, taking gotu kola 120 mg daily for 6 months was not associated with changes in liver function (11065).
In one case of hepatotoxicity, a 61-year-old female developed elevated liver transaminase and total bilirubin levels after taking gotu kola tablets for 30 days. Liver biopsy showed granulomatous acute hepatitis. Months later, the patient took gotu kola again and developed elevated liver transaminases after 2 weeks. In another case, a 52-year-old female developed symptoms of hepatitis and increased liver transaminases after taking gotu kola for 3 weeks. Biopsy indicated chronic hepatitis and granulomas, areas of necrosis, and cirrhotic transformation. Liver function normalized after discontinuation of gotu kola. In a third case, a 49-year-old female developed symptoms of hepatitis after taking gotu kola for 2 months. Biopsy revealed granulomatous hepatitis. Liver function normalized after discontinuation of gotu kola (13182). In a fourth case, a 15-year-old female taking an unknown dose of gotu kola and lymecycline for 6 weeks for acne experienced acute liver failure with abdominal pain and vomiting, as well as elevated liver transaminases, bilirubin, international normalized ratio (INR), and prothrombin. Liver function returned to normal after both products were discontinued (92506).
Immunologic ...Topically, gotu kola can cause allergic contact dermatitis, characterized by erythema, itching, papules, and a burning sensation (4,6887,9789,52875,52887,52896,52902). One specific gotu kola product (Blasteostimulina, Almirall, S. A.) has been reported to cause allergic contact dermatitis in some patients. However, not all patients who react to this product are sensitive to gotu kola; some are sensitive to neomycin, another ingredient in the product (52875). Madecassol ointment (Rona Laboratories Limited) is another gotu kola product that has resulted in allergic contact dermatitis. Controlled testing suggests that this product can cause this adverse effect in about 8% of patients (9789). Centellase cream has also caused allergic contact dermatitis in at least two cases (52887,52888).
Psychiatric ...A case of night eating syndrome has been reported for a 41-year-old female who had been taking a gotu kola tincture (dose not specified) for 2 years. Symptoms resolved after gotu kola use was discontinued (52878).
General
...Orally and topically, holy basil extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Loose stools and nausea.
Topically: Bitter taste with oral application.
Gastrointestinal
...Orally, two out of 24 participants taking capsules containing holy basil extract in one clinical study experienced nausea or loose stools (55037).
Topically, holy basil mouthwash has been reported to cause a bitter taste in clinical trials (55038).
General
...Orally and topically, red clover seems to be well tolerated.
Most Common Adverse Effects:
Orally: Myalgia, nausea, and vaginal spotting.
Dermatologic ...Orally, a specific red clover isoflavone product (Promensil) has been associated with mild cases of psoriasis and thrush, although a direct causal link has not been established (9552).
Gastrointestinal ...Orally, red clover has been reported to cause nausea (8194).
Genitourinary ...In human research, 80 mg, but not 40 mg, of a specific red clover isoflavone product (Promensil) increased the duration of menstrual cycles in patients with mastalgia (9552). Red clover has also been reported to cause vaginal spotting (8194).
Hematologic ...In one case report, a 53-year-old female had a spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero. It is not clear if this was due to red clover, another ingredient, the combination of ingredients, or other factors (70419). In another case report, a 55-year-old female with protein S deficiency and systemic lupus erythematosus (SLE) had temporary vision loss in the left eye from hemiretinal vein thrombosis 3 days after taking a combination phytoestrogen product containing red clover 250 mg, wild yam 276 mg, dong quai 100 mg, and black cohosh 250 mg (13155). It is unclear if red clover contributed to this event.
Musculoskeletal ...Orally, red clover has been reported to cause myalgia (8194).
Neurologic/CNS ...Orally, a specific red clover isoflavone product (Medoflavon) has been associated with headache, although with a similar frequency to placebo (19545).
Oncologic ...Due to potential estrogenic effects of red clover isoflavones, there has been some concern that red clover might increase the risk of estrogen-sensitive cancers such as breast cancer or uterine cancer. A meta-analysis of 8 clinical trials suggests that increased intake of red clover- and soy-derived isoflavones may modestly increase mammographic breast density in premenopausal, but not postmenopausal, adults when compared with placebo. However, in a sub-group analysis assessing only isolated red clover isoflavones, there was no change in breast density (70428). Furthermore, a 2015 review by the European Food Safety Authority (EFSA) reported no increase in risk of breast cancer in females taking isoflavone-containing supplements (91725). Similarly, no effect was found on endometrial thickness and histopathological changes in the uterus after up to 36 months of supplementation with 40-120 mg daily of isoflavones from red clover extract (91725).
General
...Orally, white sandalwood appears to be well tolerated when taken in food amounts.
There is currently a limited amount of information on the adverse effects of white sandalwood when taken in medicinal amounts. Topically and by inhalation, adverse effects to white sandalwood seem to be rare; however, a thorough safety evaluation has not been conducted.
Most Common Adverse Effects:
Orally: Itching, nausea.
Topically: Contact dermatitis.
Serious Adverse Effects (Rare):
Orally: Acute kidney injury.
Dermatologic ...Orally, white sandalwood may cause itching (18).
Gastrointestinal ...Orally, white sandalwood may cause nausea and gastrointestinal complaints (18).
Immunologic ...Topically or when inhaled, there are case reports of white sandalwood paste or oil causing contact and photoallergic contact dermatitis (73081,73082,99292).
Renal ...Orally, use of large doses of white sandalwood or for more than 6 weeks is associated with kidney damage, with blood in the urine (12,18,19).
General
...Orally, zinc is well tolerated in doses below the tolerable upper intake level (UL), which is 40 mg daily for adults.
Topically, zinc is well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, diarrhea, metallic taste, nausea and vomiting (dose-related).
Topically: Burning, discoloration, itching, stinging, and tingling when applied to irritated tissue.
Intranasally: Bad taste, dry mouth, headache, irritation, reduced sense of smell.
Serious Adverse Effects (Rare):
Orally: There have been cases of acute renal tubular necrosis, interstitial nephritis, neurological complications, severe vomiting, and sideroblastic anemia after zinc overdose.
Intranasally: There have been cases where intranasal zinc caused permanent loss of smell (anosmia).
Dermatologic
...Topically, zinc can cause burning, stinging, itching, and tingling when applied to inflamed tissue (6911,8623,87297).
Zinc oxide can be deposited in the submucosal tissue and cause dark discoloration of the skin. This can occur with prolonged topical application to intact skin, application to eroded or ulcerated skin, or penetrating traumatic exposure, and also parenteral administration (8618).
In rare cases, oral zinc has resulted in worsened acne (104056), skin sensitivity (6592), a leishmanial reaction with a macular rash that occurred on exposed parts of the body (86935), eczema (104055), systemic contact dermatitis (109457), and the development of severe seborrheic dermatitis (86946).
Gastrointestinal
...Orally, zinc can cause nausea (338,2663,2681,6592,6700,18216,106230,106233,106227,113661), vomiting (2663,2681,6519,6592,96069,96074), a metallic or objectionable taste in the mouth (336,338,6700,11350,18216,106902,113661), abdominal cramping (6592,96069), indigestion (87227), heartburn (96069), dry mouth (87533), and mouth irritation (336,2619).
When used orally in amounts above the tolerable upper intake level, zinc may cause irritation and corrosion of the gastrointestinal tract (331,86982,87315,106902), watery diarrhea (1352), epigastric pain (2663,2681), and severe vomiting (2663,2681).
Intranasally, zinc can cause bad taste, dry mouth, and burning and irritation of the throat (8628,8629).
When used topically as a mouth rinse, zinc may cause tooth staining (90206).
Hematologic ...There is concern that high daily doses of zinc, above the tolerable upper intake level (UL) of 40 mg per day, might increase the risk of copper deficiency, potentially leading to anemia and leukopenia (7135,112473). To prevent copper deficiency, some clinicians give a small dose of copper when zinc is used in high doses, long-term (7303).
Hepatic ...There are two cases of liver deterioration in patients with Wilson disease following initiation of treatment with zinc 50-200 mg three times daily. The mechanism of action is not understood, and the event is extremely uncommon (86927,87470).
Immunologic ...Daily doses of 300 mg of supplemental zinc for 6 weeks appear to impair immune response (7135). A case of erythematosus-like syndrome, including symptoms such as fever, leg ulcers, and rash, has been reported following intake of effervescent tablets (Solvezink) containing zinc 45 mg (87506). In another case, severe neutropenia was reported after taking supplemental zinc 900 mg daily for an unknown duration (112473).
Musculoskeletal ...Orally, zinc may cause body aches in children (113661).
Neurologic/CNS
...Zinc-containing denture adhesives can cause toxicity if used more frequently than recommended for several years.
Case reports describe hyperzincemia, low copper levels, blood dyscrasias, and neurological problems, including sensory disturbances, numbness, tingling, limb weakness, and difficulty walking in patients applying denture adhesive multiple times daily for several years (17092,17093,90205,90233). Due to reports of zinc toxicity associated with use of excessive amounts of zinc-containing denture adhesives for several years, GlaxoSmithKline has reformulated Polygrip products to remove their zinc content (17092,17093).
Intranasally (8628) and orally (87534), zinc can cause headache. When used orally in amounts above the tolerable upper intake level (UL), zinc may cause central nervous system (CNS) symptoms including lethargy, fatigue, neuropathy, dizziness, and paresthesia (2663,2681,87369,87470,87533,87534,112473).
Oncologic ...There is concern that zinc might worsen prostate disease. For example, some preliminary evidence suggests that higher dietary zinc intake increases the risk for benign prostatic hyperplasia (6908). Epidemiological evidence suggests that taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer (10306). Another large-scale population study also suggests that men who take a multivitamin more than 7 times per week and who also take a separate zinc supplement have a significantly increased risk of prostate cancer-related mortality (15607). However, a large analysis of population research suggests that there is no association between zinc intake and the risk of prostate cancer (96075).
Pulmonary/Respiratory
...There are several hundred reports of complete loss of sense of smell (anosmia) that may be permanent with use of zinc gluconate nasal gel, such as Zicam (11306,11155,11707,16800,16801,17083,86999,87535).
Loss of sense of smell is thought to be dose related but has also been reported following a single application (11306,11155,11707,16800). Patients often report having sniffed deeply when applying the gel, then experiencing an immediate burning sensation, and noticing anosmia within 48 hours (17083). On June 16, 2009, the US Food and Drug Administration (FDA) advised patients not to use a specific line of commercial zinc nasal products (Zicam) after receiving 130 reports of loss of smell (16800). The manufacturer of these products had also received several hundred reports of loss of smell related to its intranasal zinc products (16801). Zinc sulfate nasal spray was used unsuccessfully for polio prophylaxis before the polio vaccine was developed. It caused loss of smell and/or taste, which was sometimes permanent (11713). Animal studies suggest that zinc sulfate negatively affects smell, possibly by damaging the olfactory epithelium and neurons (11156,11703,11704,11705,11706). Zinc gluconate nasal spray has not been tested for safety in animals or humans. The clinical studies of intranasal zinc have not described anosmia as an adverse effect, but testing was not done to see if zinc use adversely affected sense of smell (6471,8628,8629,10247). Also, these clinical studies reported tingling or burning sensation in the nostril, dry nose, nose pain, and nosebleeds.
When used in amounts above the tolerable upper intake level (UL), zinc may cause flu-like symptoms including coughing (2663).
Renal ...In overdose, zinc can cause acute renal tubular necrosis and interstitial nephritis (331,1352,87338).
Other ...Occupational inhalation of zinc oxide fumes can cause metal fume fever with symptoms including fatigue, chills, fever, myalgias, cough, dyspnea, leukocytosis, thirst, metallic taste, and salivation (331).
