|
Theoretically, peppermint oil might increase the levels and adverse effects of cyclosporine.
Details
In animal research, peppermint oil inhibits cyclosporine metabolism and increases cyclosporine levels. Inhibition of cytochrome P450 3A4 (CYP3A4) may be partially responsible for this interaction (11784). An interaction between peppermint oil and cyclosporine has not been reported in humans.
|
Theoretically, peppermint might increase the levels of CYP1A2 substrates.
Details
In vitro and animal research shows that peppermint oil and peppermint leaf inhibit CYP1A2 (12479,12734). However, in clinical research, peppermint tea did not significantly affect the metabolism of caffeine, a CYP1A2 substrate. It is possible that the 6-day duration of treatment may have been too short to identify a difference (96359).

Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of alkylating agents but might also reduce the oxidative damage caused by certain alkylating agents.
Details
Rose hip contains vitamin C. The use of antioxidants like vitamin C during chemotherapy is controversial. There is concern that antioxidants could reduce the activity of chemotherapy drugs that generate free radicals, such as cyclophosphamide, chlorambucil, carmustine, busulfan, and thiotepa (391). In contrast, some researchers theorize that antioxidants might make chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). Further, some animal research suggests that the antioxidant effects of rose hip might attenuate cyclophosphamide-induced testicular toxicity (111413). More evidence is needed to determine what effect, if any, antioxidants found in rose hip, such as vitamin C, have on the effectiveness and adverse effects of chemotherapy.
|
Theoretically, rose hip might increase the amount of aluminum absorbed from aluminum compounds.
Details
Rose hip contains vitamin C. Theoretically, vitamin C increases the absorption of aluminum. Concomitant use might increase aluminum absorption, but the clinical significance of this is unknown (3046). Administer rose hip two hours before or four hours after antacids.
|
Theoretically, rose hip might reduce the effectiveness of anticoagulant or antiplatelet drugs.
Details
In vitro and animal research suggests that a constituent of rose hip, rugosin E, can induce platelet aggregation (71653). This has not been shown in humans. Theoretically, concomitant use of rose hip might reduce the effectiveness of antiplatelet or anticoagulant drugs.
|
Theoretically, the antioxidant effects of rose hip might reduce the effectiveness of antitumor antibiotics.
Details
Rose hip contains the antioxidant vitamin C. There is concern that antioxidants might reduce the activity of chemotherapy drugs that generate free radicals, such as antitumor antibiotics (391). In contrast, other researchers theorize that antioxidants might make antitumor antibiotic chemotherapy more effective by reducing oxidative stress that could interfere with apoptosis (cell death) of cancer cells (14012,14013). More evidence is needed to determine what effects, if any, antioxidants such as vitamin C have on antitumor antibiotic chemotherapy.
|
Theoretically, rose hip might reduce the clearance of aspirin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Rose hip contains vitamin C. It has been suggested that acidification of the urine by vitamin C can decrease the urinary excretion of salicylates, increasing plasma salicylate levels (3046). However, short-term use of up to 6 grams daily of vitamin C does not seem to affect urinary pH or salicylate excretion (10588,10589). The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and aspirin is unlikely.
|
Theoretically, rose hip might increase blood levels of estrogens.
Details
Rose hip contains vitamin C. Increases in plasma estrogen levels of up to 55% have occured under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products (129,130,11161). It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall (129,11161). When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements (11161).
|
Theoretically, rose hip might increase blood levels of lithium.
Details
|
Theoretically, rose hip might reduce the effectiveness of warfarin; however, its vitamin C content is likely too low to produce clinically significant effects.
Details
Rose hip contains vitamin C. High doses of vitamin C may reduce the response to warfarin, possibly by causing diarrhea and reducing warfarin absorption (11566). This occurred in two people who took up to 16 grams daily of vitamin C, and resulted in decreased prothrombin time (9804,9806). Lower doses of 5-10 grams daily of vitamin C can also reduce warfarin absorption, but this does not seem to be clinically significant (9805,9806,11566,11567). The vitamin C content of rose hip is typically about 500 mg per 100 grams. Thus, a clinically significant interaction between rose hip and warfarin is unlikely.

Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research suggests that curcumin, a constituent of turmeric, inhibits mechlorethamine-induced apoptosis of breast cancer cells by up to 70%. Also, animal research shows that curcumin inhibits cyclophosphamide-induced tumor regression (96126). However, some in vitro research shows that curcumin does not affect the apoptosis capacity of etoposide. Also, other laboratory research suggests that curcumin might augment the cytotoxic effects of alkylating agents. Reasons for the discrepancies may relate to the dose of curcumin and the specific chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have on alkylating agents.
|
Taking turmeric with amlodipine may increase levels of amlodipine.
Details
Animal research shows that giving amlodipine 1 mg/kg as a single dose following the use of turmeric extract 200 mg/kg daily for 2 weeks increases the maximum concentration and area under the curve by 53% and 56%, respectively, when compared with amlodipine alone (107113). Additional animal research shows that taking amlodipine 1 mg/kg with a curcumin 2 mg/kg pretreatment for 10 days increases the maximum concentration and area under the curve by about 2-fold when compared with amlodipine alone (103099).
|
Turmeric may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Details
Curcumin, a constituent of turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271). Furthermore, two case reports have found that taking turmeric along with warfarin or fluindione was associated with an increased international normalized ratio (INR) (89718,100906). However, one clinical study in healthy volunteers shows that taking curcumin 500 mg daily for 3 weeks, alone or with aspirin 100 mg, does not increase antiplatelet effects or bleeding risk (96137). It is possible that the dose of turmeric used in this study was too low to produce a notable effect.
|
Theoretically, taking turmeric with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Animal research and case reports suggest that curcumin, a turmeric constituent, can reduce blood glucose levels in patients with diabetes (79692,79984,80155,80313,80315,80476,80553,81048,81219). Furthermore, clinical research in adults with type 2 diabetes shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg decreased postprandial glucose levels for up to 24 hours when compared with glyburide alone, despite the lack of a significant pharmacokinetic interaction (96133). Another clinical study in patients with diabetes on hemodialysis shows that taking curcumin 80 mg daily for 12 weeks can reduce blood glucose levels when compared with placebo (104149).

Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro and animal research shows that curcumin, a constituent of turmeric, inhibits doxorubicin-induced apoptosis of breast cancer cells by up to 65% (96126). However, curcumin does not seem to affect the apoptosis capacity of daunorubicin. In fact, some research shows that curcumin might augment the cytotoxic effects of antitumor antibiotics, increasing their effectiveness. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effects, if any, antioxidants such as turmeric have on antitumor antibiotics.

Theoretically, turmeric might increase or decrease levels of drugs metabolized by CYP1A1. However, research is conflicting.
Details
|
Theoretically, turmeric might increase levels of drugs metabolized by CYP1A2. However, research is conflicting.
Details
|
Theoretically, turmeric might increase levels of drugs metabolized by CYP3A4.
Details
In vitro and animal research show that turmeric and its constituent curcumin inhibit CYP3A4 (21497,21498,21499). In one case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels of 29 ng/mL. The patient previously had tacrolimus levels within the therapeutic range at 9.7 ng/mL. Ten days prior to presenting to the emergency room the patient started consumption of turmeric powder at a dose of 15 or more spoonfuls daily. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition (93544).
|
Theoretically, turmeric might increase blood levels of oral docetaxel.
Details
Animal research suggests that the turmeric constituent, curcumin, enhances the oral bioavailability of docetaxel (80999). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
|
Theoretically, large amounts of turmeric might interfere with hormone replacement therapy through competition for estrogen receptors.
Details
In vitro research shows that curcumin, a constituent of turmeric, displaces the binding of estrogen to its receptors (21486).
|
Theoretically, taking turmeric and glyburide in combination might increase the risk of hypoglycemia.
Details
Clinical research shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg increases blood levels of glyburide by 12% at 2 hours after the dose in patients with type 2 diabetes. While maximal blood concentrations of glyburide were not affected, turmeric modestly decreased postprandial glucose levels for up to 24 hours when compared to glyburide alone, possibly due to the hypoglycemic effect of turmeric demonstrated in animal research (96133).
|
Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
Details
|
Theoretically, turmeric might increase the effects of losartan.
Details
Research in hypertensive rats shows that taking turmeric can increase the hypotensive effects of losartan (110897).
|
Theoretically, turmeric might increase the effects and adverse effects of norfloxacin.
Details
Animal research shows that taking curcumin, a turmeric constituent, can increase blood levels of orally administered norfloxacin (80863).
|
Theoretically, turmeric might increase the absorption of P-glycoprotein substrates.
Details
|
Theoretically, turmeric might alter blood levels of paclitaxel, although any effect may not be clinically relevant.
Details
Clinical research in adults with breast cancer receiving intravenous paclitaxel suggests that taking turmeric may modestly alter paclitaxel pharmacokinetics. Patients received paclitaxel on day 1, followed by either no treatment or turmeric 2 grams daily from days 2-22. Pharmacokinetic modeling suggests that turmeric reduces the maximum concentration and area under the curve of paclitaxel by 12.1% and 7.7%, respectively. However, these changes are not likely to be considered clinically relevant (108876). Conversely, animal research suggests that curcumin, a constituent of turmeric, enhances the oral bioavailability of paclitaxel (22005). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
|
Turmeric might increase the effects and adverse effects of sulfasalazine.
Details
Clinical research shows that taking the turmeric constituent, curcumin, can increase blood levels of sulfasalazine by 3.2-fold (81131).
|
Turmeric might increase the effects and adverse effects of tacrolimus.
Details
In one case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels of 29 ng/mL. The patient previously had tacrolimus levels within the therapeutic range at 9.7 ng/mL. Ten days prior to presenting at the emergency room the patient started consumption of turmeric powder at a dose of 15 or more spoonfuls daily. It was thought that turmeric increased levels of tacrolimus due to cytochrome P450 3A4 (CYP3A4) inhibition (93544). In vitro and animal research show that turmeric and its constituent curcumin inhibit CYP3A4 (21497,21498,21499).
|
Turmeric may reduce the absorption of talinolol in some situations.
Details
Clinical research shows that taking curcumin for 6 days decreases the bioavailability of talinolol when taken together on the seventh day (80079). The clinical significance of this effect is unclear.
|
Theoretically, turmeric might reduce the levels and clinical effects of tamoxifen.
Details
In a small clinical trial in patients with breast cancer taking tamoxifen 20-30 mg daily, adding curcumin 1200 mg plus piperine 10 mg three times daily reduces the 24-hour area under the curve of tamoxifen and the active metabolite endoxifen by 12.8% and 12.4%, respectively, as well as the maximum concentrations of tamoxifen, when compared with tamoxifen alone. However, in the absence of piperine, the area under the curve for endoxifen and the maximum concentration of tamoxifen were not significantly reduced. Effects were most pronounced in patients who were extensive cytochrome P450 (CYP) 2D6 metabolizers (107123).
|
Turmeric has antioxidant effects. There is some concern that this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research shows that curcumin, a constituent of turmeric, inhibits camptothecin-induced apoptosis of breast cancer cells by up to 71% (96126). However, other in vitro research shows that curcumin augments the cytotoxic effects of camptothecin. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agents. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have.
|
Turmeric might increase the risk of bleeding with warfarin.
Details
One case of increased international normalized ratio (INR) has been reported for a patient taking warfarin who began taking turmeric. Prior to taking turmeric, the patient had stable INR measurements. Within a few weeks of starting turmeric supplementation, the patient's INR increased to 10 (100906). Additionally, curcumin, the active constituent in turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271), which may produce additive effects when taken with warfarin.
|
White sandalwood is thought to have diuretic properties. Theoretically, due to these potential diuretic effects, white sandalwood might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

...Orally, neem extracts seem to be well tolerated in adults.
However, high-quality assessment of safety has not been conducted. In children, oral use of neem oil can cause serious adverse effects. Topically, neem seems to be well tolerated in children and adults.
Most Common Adverse Effects:
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Cardiac arrest, nephrotoxicity, and ventricular fibrillation with neem leaf in adults. Encephalopathy, hematologic abnormalities, hepatotoxicity, and nephrotoxicity with neem oil in infants and young children.
Cardiovascular ...Orally, neem leaf has been reported to cause ventricular fibrillation and cardiac arrest after ingestion in humans (64873,64870).
Dental ...Topically, use of neem twigs to brush teeth, which is a traditional dental hygiene practice in India, has been associated with vitiligo of the lips. The limonoid constituents in neem, which have been shown to inhibit melanogenesis and have cytotoxic effects, combined with repeated, local trauma from this dental hygiene practice are thought to cause this leucodermic reaction. In a case series of seven patients experiencing vitiligo of the lips from neem twigs, use of toothpaste and topical tacrolimus along with avoidance of neem stopped the progression of depigmentation in all patients. Repigmentation was reported in four of the seven patients 12 months after discontinuing neem-based dental hygiene practices (100958).
Dermatologic ...Topically, neem products have been associated with dermatologic reactions. Some case reports have associated the use of topical neem oil with contact dermatitis (64851,94568,102867). In one case series, the topical application of neem seed extract shampoo was associated with skin irritation, red spots, and a burning feeling of the scalp (64848). Use of neem twigs to brush teeth, which is a traditional dental hygiene practice in India, has been associated with vitiligo of the lips. The limonoid constituents in neem, which have been shown to inhibit melanogenesis and have cytotoxic effects, combined with repeated, local trauma from this dental hygiene practice are thought to cause this leucodermic reaction. In a case series of seven patients experiencing vitiligo of the lips from neem twigs, use of toothpaste and topical tacrolimus along with avoidance of neem stopped the progression of depigmentation in all patients. Repigmentation was reported in four of the seven patients 12 months after discontinuing neem-based dental hygiene practices (100958).
Gastrointestinal ...Orally, neem oil has been reported to cause vomiting and loose stools in infants and small children (3473,3474,3476,64865).
Genitourinary ...Orally, neem leaf has been reported to cause oliguria and anuria in adults (12833,12834). After a single intrauterine instillation, purified neem oil has been reported to cause endometritis in healthy, tubectomised females (64886).
Hematologic
...Orally, neem leaf has been reported to cause hemolysis in adults (12835).
In one case report, a 35-year-old male with diabetes and glucose-6-phosphate dehydrogenase (G6PD) deficiency developed hemolytic anemia and jaundice after drinking several liters of neem tea daily for 3 weeks. All symptoms resolved after discontinuation and supportive treatment (94571). Orally, neem oil has been reported to cause metabolic acidosis, anemia, and polymorphonuclear leukocytosis in infants and young children (3473,3474,3476,64865).
A single intrauterine instillation of purified neem oil has been reported to cause mild transient eosinophilia in healthy, tubectomised females (64886).
Hepatic ...Orally, neem oil has been associated with reports of hepatotoxicity in infants and children. These adverse effects occurred after single doses of neem oil ranging from a few drops to 60 mL. Pathologic findings on liver biopsy reports have been consistent with Reye-like syndrome (3473,3474,3475).
Immunologic ...Topically, a case of aggravated bullous pemphigoid requiring hospitalization is reported in a 47-year-old patient with this autoimmune condition after application of neem oil to blisters for an unknown duration (111715).
Neurologic/CNS ...Orally, single doses of neem oil ranging from a few drops to 60 mL have been associated with reports of encephalopathy in infants and small children. Symptoms include drowsiness, seizure, loss of consciousness, coma, cerebral edema, Reye-like syndrome, and death within hours of ingestion (3473,3474,3476,3476,64855,94750). There is also at least one case report of neurotoxicity in an adult after ingestion of a neem-based pesticide. A 35-year-old female experienced neurotoxicity requiring intensive medical care and ventilation after ingestion of a pesticide containing azadirachtin, a constituent of neem oil (64858).
Ocular/Otic ...In one case report, a 35-year-old female developed toxic optic neuropathy and vision loss in both eyes lasting for two days after consuming 150 mL of neem oil in a suicide attempt five days earlier (64856).
Renal ...Orally, neem leaf has been reported to cause oliguria, anuria, acute tubular necrosis, and nephrotoxicity in adults (12833,12834). There are some case reports of children developing Reye-like syndrome after ingestion of neem oil. Pathologic findings on renal biopsy reports have been consistent with Reye syndrome (3473,3474,3475).
General
...Orally, topically, or rectally, peppermint oil is generally well tolerated.
Inhaled,
peppermint oil seems to be well tolerated. Intranasally, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted. Orally, peppermint leaf seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, anal burning, belching, diarrhea, dry mouth, heartburn, nausea, and vomiting.
Topically: Burning, dermatitis, irritation, and redness.
Dermatologic
...Topically, peppermint oil can cause skin irritation, burning, erythema, and contact dermatitis (3802,11781,31528,43338,68473,68457,68509,96361,96362).
Also, a case of severe mucosal injury has been reported for a patient who misused an undiluted over the counter mouthwash that contained peppermint and arnica oil in 70% alcohol (19106).
In large amounts, peppermint oil may cause chemical burns when used topically or orally. A case of multiple burns in the oral cavity and pharynx, along with edema of the lips, tongue, uvula, and soft palate, has been reported for a 49-year-old female who ingested 40 drops of pure peppermint oil. Following treatment with intravenous steroids and antibiotics, the patient's symptoms resolved over the course of 2 weeks (68432). Also, a case of chemical burns on the skin and skin necrosis has been reported for a 35-year-old male who spilled undiluted peppermint oil on a previous skin graft (68572). Oral peppermint oil has also been associated with burning mouth syndrome and chronic mouth ulceration in people with contact sensitivity to peppermint (6743). Also, excessive consumption of mint candies containing peppermint oil has been linked to cases of stomatitis (13114).
Gastrointestinal ...Orally, peppermint oil can cause heartburn, nausea and vomiting, anal or perianal burning, abdominal pain, belching, dry mouth, diarrhea, and increased appetite (3803,6740,6741,6742,10075,11779,11789,17682,68497,68514)(68532,68544,96344,96360,102602,104219,107955). Enteric-coated capsules might help to reduce the incidence of heartburn (3802,4469,6740,11777). However, in one clinical study, a specific enteric-coated formulation of peppermint oil (Pepogest; Nature's Way) taken as 180 mg three times daily was associated with a higher rate of adverse effects when compared with placebo (48% versus 31%, respectively). Specifically, of the patients consuming this product, 11% experienced belching and 26% experienced heartburn, compared to 2% and 12%, respectively, in the placebo group (107955). A meta-analysis of eight small clinical studies in patients with irritable bowel syndrome shows that taking enteric-coated formulations of peppermint oil increases the risk of gastroesophageal reflux symptoms by 67% when compared with a control group (109980). Enteric-coated capsules can also cause anal burning in people with reduced bowel transit time (11782,11789).
Genitourinary ...Orally, a sensitive urethra has been reported rarely (102602).
Hepatic ...One case of hepatocellular liver injury has been reported following the oral use of peppermint. Symptoms included elevated liver enzymes, fatigue, jaundice, dark urine, and signs of hypersensitivity. Details on the dosage and type of peppermint consumed were unavailable (96358).
Immunologic ...One case of IgE-mediated anaphylaxis, characterized by sudden onset of lip and tongue swelling, tightness of throat, and shortness of breath, has been reported in a 69-year-old male who consumed peppermint candy (89479). An allergic reaction after use of peppermint oil in combination with caraway oil has been reported in a patient with a history of bronchial asthma (96344). It is not clear if this reaction occurred in response to the peppermint or caraway components.
Neurologic/CNS ...Orally, headache has been reported rarely (102602).
Ocular/Otic ...Orally, peppermint has been reported to cause blurry vision (3803).
General
...Orally, rose hip from Rosa canina is well tolerated.
Rose hip from Rosa damascena also seems to be well tolerated. A thorough evaluation of safety outcomes has not been conducted for rose hip derived from other species.
Most Common Adverse Effects:
Orally: Flatulence, loose stools.
Dermatologic ...Orally, one case of mild urticaria has been reported in a clinical trial for a patient taking a specific rose hip powder product (LitoZin/i-flex, Hyben Vital) 2. 5 grams twice daily (71646).
Gastrointestinal
...Orally, gastrointestinal reactions have been reported.
These include abdominal cramps, acid reflux, constipation, diarrhea, flatulence, nausea, vomiting, gastrointestinal obstruction, esophagitis, heartburn, acid reflux, and water brash. However, in most cases, these adverse effects occurred at the same frequency in patients taking placebo (15,18104,71641,71646,97938).
Rose hip powder is a source of vitamin C. Osmotic diarrhea and gastrointestinal upset have been reported with doses of vitamin C greater than the tolerable upper intake level (UL) of 2000 mg daily (4844). However, most rose hip products contain only 500 mg of vitamin C per 100 grams.
Genitourinary ...Orally, a few mild cases of frequent voiding have been reported in clinical trials. However, the frequency of occurrence does not seem to differ from those taking placebo (71641,71646).
Immunologic ...When inhaled in the workplace, rose hip dust has caused mild to moderate anaphylaxis (6).
Neurologic/CNS ...Orally, vertigo and headache have been reported rarely (97938).
Ocular/Otic ...A case of keratoconjunctivitis secondary to contact with rose hip has been reported. The adverse effect was attributed to irritant hairs found on the fruit of rose hip. Symptoms resolved after treatment with topical prednisolone 1% eye drops (71642).
General
...Orally and topically, turmeric is generally well tolerated.
Most Common Adverse Effects:
Orally: Constipation, dyspepsia, diarrhea, distension, gastroesophageal reflux, nausea, and vomiting.
Topically: Curcumin, a constituent of turmeric, can cause contact urticaria and pruritus.
Cardiovascular ...Orally, a higher dose of turmeric in combination with other ingredients has been linked to atrioventricular heart block in one case report. It is unclear if turmeric caused this adverse event or if other ingredients or a contaminant were the cause. The patient had taken a combination supplement containing turmeric 1500-2250 mg, black soybean 600-900 mg, mulberry leaves, garlic, and arrowroot each about 300-450 mg, twice daily for one month before experiencing atrioventricular heart block. Heart rhythm normalized three days after discontinuation of the product. Re-administration of the product resulted in the same adverse effect (17720).
Dermatologic ...Following occupational and/or topical exposure, turmeric or its constituents curcumin, tetrahydrocurcumin, or turmeric oil, can cause allergic contact dermatitis (11146,79270,79470,79934,81410,81195). Topically, curcumin can also cause rash or contact urticaria (79985,97432,112117). In one case, a 60-year-old female, with no prior reactivity to regular oral consumption of turmeric products, developed urticaria after topical application of turmeric massage oil (97432). A case of pruritus has been reported following topical application of curcumin ointment to the scalp for the treatment of melanoma (11148). Orally, curcumin may cause pruritus, but this appears to be relatively uncommon (81163,97427,104148). Pitting edema may also occur following oral intake of turmeric extract, but the frequency of this adverse event is less common with turmeric than with ibuprofen (89720). A combination of curcumin plus fluoxetine may cause photosensitivity (89728).
Gastrointestinal ...Orally, turmeric can cause gastrointestinal adverse effects (107110,107112,112118), including constipation (81149,81163,96135), flatulence and yellow, hard stools (81106,96135), nausea and vomiting (10453,17952,89720,89728,96127,96131,96135,97430,112117,112118), diarrhea or loose stool (10453,17952,18204,89720,96135,110223,112117,112118), dyspepsia (17952,89720,89721,96161,112118), gastritis (89728), distension and gastroesophageal reflux disease (18204,89720), abdominal fullness and pain (81036,89720,96161,97430), epigastric burning (81444), and tongue staining (89723).
Hepatic
...Orally, turmeric has been associated with liver damage, including non-infectious hepatitis, cholestasis, and hepatocellular liver injury.
There have been at least 70 reports of liver damage associated with taking turmeric supplements for at least 2 weeks and for up to 14 months. Most cases of liver damage resolved upon discontinuation of the turmeric supplement. Sometimes, turmeric was used concomitantly with other supplements and medications (99304,102346,103094,103631,103633,103634,107122,109288,110221). The Drug-Induced Liver Injury Network (DILIN) has identified 10 cases of liver injury which were considered to be either definitely, highly likely, or probably associated with turmeric; none of these cases were associated with the use of turmeric in combination with other potentially hepatotoxic supplements. Most patients (90%) presented with hepatocellular pattern of liver injury. The median age of these case reports was 56 years and 90% identified as White. In these case reports, the carrier frequency on HLAB*35:01 was 70%, which is higher than the carrier frequency found in the general population. Of the ten patients, 5 were hospitalized and 1 died from liver injury (109288).
It is not clear if concomitant use with other supplements or medications contributes to the risk for liver damage. Many case reports did not report turmeric formulation, dosing, or duration of use (99304,103094,103631,103634,109288). However, at least 10 cases involved high doses of curcumin (250-1812.5 mg daily) and the use of highly bioavailable formulations such as phytosomal curcumin and formulations containing piperine (102346,103633,107122,109288,110221).
Neurologic/CNS ...Orally, the turmeric constituent curcumin can cause vertigo, but this effect seems to be uncommon (81163).
Psychiatric ...Orally, the turmeric constituent curcumin or a combination of curcumin and fluoxetine can cause giddiness, although this event seems to be uncommon (81206,89728).
Other ...There is a single case report of death associated with intravenous use of turmeric. However, analysis of the treatment vial suggests that the vial contained only 0.023% of the amount of curcumin listed on the label. Also, the vial had been diluted in a solution of ungraded polyethylene glycol (PEG) 40 castor oil that was contaminated with 1.25% diethylene glycol. Therefore the cause of death is unknown but is unlikely to be related to the turmeric (96136).
General ...Orally, white sandalwood may cause itching, nausea, gastrointestinal complaints, and blood in the urine (18). Use of large doses or for more than 6 weeks is associated with kidney damage (12,19). Topically, contact dermatitis can occur in sensitive individuals (73081,73082,99292).
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).
