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.

There are some reports suggesting that alpinia increases stomach acid (19).
|
Theoretically, alpinia might decrease the effectiveness of H2-blockers.
Details
There are some reports suggesting that alpinia increases stomach acid (19).
|
Theoretically, alpinia might reduce the levels and clinical effects of indomethacin.
Details
In animals, giving an alpinia extract orally reduces systemic exposure to indomethacin, reduces its retention time in plasma, and accelerates its elimination in the bile and feces (106738). This interaction has not been reported in humans.
|

Details
|
Theoretically, American ginseng can interfere with MAOI therapy.
Details
There is one case report of insomnia, headache, and tremors when an unspecified ginseng product was used with phenelzine (Nardil), an MAOI (617). There is also one case report of hypomania when an unspecified ginseng product was used with phenelzine (618). Theoretically, American ginseng may interfere with MAOI therapy.

Theoretically, taking astragalus with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, astragalus might interfere with cyclophosphamide therapy.
Details
|
Theoretically, astragalus might interfere with immunosuppressive therapy.
Details
|
Theoretically, astragalus might increase levels and adverse effects of lithium.
Details
Animal research suggests that astragalus has diuretic properties (15103). Theoretically, due to this diuretic effect, astragalus might reduce excretion and increase levels of lithium.
|
Theoretically, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.
Details
Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals (7591,73535,74932,74956,74988,74990). A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels (91509). However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo (12536). These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.
Details
In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2 (7532). This effect has not been reported in humans.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2C9.
Details
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9 (7532). This effect has not been reported in humans.
|

Details
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.
Details
|
Eleuthero might increase serum digoxin levels and increase the risk of side effects.
Details
In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal (543). It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay (15585). Although the product was found to be free of digoxin and digitoxin (543), it was not tested for other contaminants (797).
|
Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.
Details
|
Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.
Details
In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1 (35450). Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.
|
Theoretically, eleuthero might increase levels of P-glycoprotein substrates.
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.
|
Javanese turmeric might increase the risk of bleeding with warfarin.
Details
Animal research suggests that administering high doses of oral Javanese turmeric daily for 7 days prior to a single dose of intravenous warfarin, or for 3 days in combination with intravenous warfarin, increases blood levels of warfarin. This increase did not occur with lower doses (106094). This effect has not been reported in humans.
|
Theoretically, taking rhodiola with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking rhodiola with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, rhodiola might increase levels of drugs metabolized by CYP1A2.
Details
In vitro research shows that rhodiola inhibits CYP1A2. This effect is highly variable and appears to be dependent on the rhodiola product studied (96461). However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of caffeine, a CYP1A2 substrate (96463).
|
Theoretically, rhodiola might increase levels of drugs metabolized by CYP2C9.
Details
In vitro research shows that rhodiola inhibits CYP2C9. This effect is highly variable and appears to be dependent on the rhodiola product studied (96461). Also, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours (96463).
|
Theoretically, rhodiola might increase levels of drugs metabolized by CYP3A4.
Details
In vitro research shows that rhodiola inhibits CYP3A4 (19497,96461). This effect is highly variable and appears to be dependent on the rhodiola product studied (96461). However, a clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days does not inhibit the metabolism of midazolam, a CYP3A4 substrate (96463).
|
Theoretically, rhodiola use might interfere with immunosuppressive therapy.
Details
|
Rhodiola might increase the levels and adverse effects of losartan.
Details
A clinical study in healthy young males found that taking rhodiola extract 290 mg daily for 14 days reduces the metabolism of losartan, a CYP2C9 substrate, by 21% after 4 hours (96463).
|
Theoretically, rhodiola might increase levels of P-glycoprotein substrates.
Details
In vitro research shows that rhodiola inhibits P-glycoprotein (19497). Theoretically, using rhodiola with P-glycoprotein substrates might increase drug levels and potentially increase the risk of adverse effects.
|
Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.
Details
In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively (109636).
|
Schisandra can increase the levels and clinical effects of cyclosporine.
Details
A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations (109637).
|
Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.
Details
In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate (105566). Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.
|
Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.
Details
In vitro and animal research suggests that schisandra induces CYP2C9 enzymes (14441). This effect has not been reported in humans.
|
Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.
Details
Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol (13220,17414,23717,91386,91388,91387,96631,105564,109636,109638,109639,109640,109641). Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism (14441), this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.
|
Schisandra can increase the levels and clinical effects of midazolam.
Details
A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra (91388).
|
Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
Details
In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines (17414,105643,105644). Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate (91386). Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.
|
Schisandra can increase the levels and clinical effects of sirolimus.
Details
A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter (105643).
|
Schisandra can increase the levels and clinical effects of tacrolimus.
Details
Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73% (17414,91387,15570,96631,105623,109638,109639,109640,109641,112889)(112890,112972,112973,112974). This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra (17414,96631,105623,105643,105644,112974). Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors (105623,109638,109639,109640,112889,112890,112973,112974). Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus (105564), and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner (109639,109640,112972).

A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra (91386).

Theoretically, schisandra might increase the levels and clinical effects of voriconazole.
Details
Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra (105566). However, this interaction has not been reported in humans.
|
Theoretically, schisandra might decrease the levels and clinical effects of warfarin.
Details
Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra (14441). However, this interaction has not been reported in humans.

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
|
Turmeric might increase levels of drugs metabolized by CYP3A4.
Details
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4 (21497,21498,21499). Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib (111644). In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. 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 have additive effects when used with hepatotoxic drugs such as methotrexate.
Details
In one case report, a 39-year-old female taking methotrexate, turmeric, and linseed oil developed hepatotoxicity (111644).
|
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 blood levels of OATP4C1 substrates.
Details
In vitro research shows that the turmeric constituent curcumin competitively inhibits OATP4C1 transport. This transporter is expressed in the kidney and facilitates the renal excretion of certain drugs (113337). Theoretically, taking turmeric might decrease renal excretion of OATP substrates.
|
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.

Below is general information about the adverse effects of the known ingredients contained in the product Stress Take Care. 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 and topically, alpinia seems to be well tolerated.
Gastrointestinal ...Orally, alpinia may cause gastrointestinal adverse effects. In one clinical trial, around 5% of patients taking alpinia extract 100 mg three times daily for 12 weeks discontinued treatment due to adverse gastrointestinal effects (102094).
General
...Orally and intravenously, astragalus root seems to be well tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: A case report raises concerns about liver and kidney cysts with astragalus use.
Cardiovascular ...Orally, astragalus has reportedly been associated with lacunar angina in one clinical trial. However, this may not have been caused by astragalus (17355). In addition, rapid intravenous administration of astragalus has resulted in temporary palpitations (32812).
Dermatologic ...Intravenously, astragalus may cause rash, eczema, and pruritus (33034).
Gastrointestinal ...Orally, astragalus has reportedly been associated with enterocolitis and nausea in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Genitourinary ...Orally, astragalus has reportedly been associated with vulvitis in one clinical trial. However, this effect may not have been caused by astragalus (17355).
Hepatic ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
Musculoskeletal ...Orally, astragalus has been associated with reports of musculoskeletal pain in one clinical trial. However, these effects may not have been caused by astragalus (114803).
Neurologic/CNS ...Intravenously, administration of astragalus has been associated with temporary dizziness in patients with heart failure in clinical research (32812,114804). Orally, astragalus has also been associated with dizziness in one clinical study. However, these effects may not have been caused by astragalus (114803).
Pulmonary/Respiratory ...Orally, astragalus has reportedly been associated with rhinosinusitis and pharyngitis in one clinical trial. However, these effects may not have been caused by astragalus (17355).
Renal ...A case of high serum CA19-9 levels and small liver and kidney cysts has been reported for a 38-year-old woman who drank astragalus tea daily for one month. Levels returned to normal after one month, and cysts disappeared after ten months. Both symptoms returned following a resumption of astragalus use. The authors state that astragalus was the likely cause given the temporal relationship (90658).
General
...Orally, eleuthero root is generally well tolerated when used short-term.
Most Common Adverse Effects:
Orally: Diarrhea, dyspepsia, gastrointestinal upset, headache, nausea, and urticaria.
Cardiovascular ...Orally, increased blood pressure has been reported in children with hypotension taking eleuthero in one clinical study (74980). Eleuthero has been reported to cause tachycardia, hypertension, and pericardial pain in patients with rheumatic heart disease or atherosclerosis. It is unclear if these effects were caused by eleuthero, or by the cardioglycoside-containing herb, silk vine (Periploca sepium), which is a common adulterant found in eleuthero products (12,797,6500).
Dermatologic ...Orally, eleuthero has been reported to cause rash in some clinical studies (75013,75028).
Gastrointestinal ...Orally, eleuthero has been reported to cause dyspepsia, nausea, diarrhea, and gastrointestinal upset in some patients (74938,75028,91510).
Genitourinary ...Orally, mastalgia and uterine bleeding were reported in 7. 3% of females taking eleuthero 2 grams daily in one clinical study (6500,11099). These adverse effects seem to be more likely with higher doses.
Neurologic/CNS
...Orally, headaches have been reported in 9.
8% of people taking eleuthero in one clinical study (11099).
In one case report, a 53-year-old female developed spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero (70419). It is unclear if this event was related to the use of eleuthero, the other ingredients, the combination, or another cause entirely.
Psychiatric ...Orally, nervousness has been reported in 7. 3% of people taking eleuthero in one clinical study (11099). Eleuthero has also been reported to cause slight anxiety, irritability, and melancholy in some patients (6500,11099). These adverse effects seem to be more likely to occur with higher doses.
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
...Orally, Javanese turmeric seems to be well tolerated when used short-term.
Most Common Adverse Effects:
Orally: Gastric irritation and nausea.
Gastrointestinal ...Orally, Javanese turmeric can cause gastric irritation and nausea when used in large amounts or for prolonged periods of time (2,8).
General
...Orally, rhodiola seems to be well tolerated.
Most Common Adverse Effects:
Orally: Dizziness, increased or decreased production of saliva.
Gastrointestinal ...Orally, rhodiola extract may cause dry mouth or excessive saliva production (16410,16411).
Neurologic/CNS ...Orally, rhodiola extract can cause dizziness (16410).
General
...Orally, schisandra seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Decreased appetite, heartburn, stomach upset, and urticaria.
Dermatologic ...Orally, schisandra can cause urticaria in some patients (11).
Gastrointestinal ...Orally, schisandra can cause heartburn, decreased appetite, and stomach upset (11).
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). Yellow discoloration of the skin has been reported rarely in clinical research (113356). 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 (81149,81163,96135,113355), 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).
Renal ...Orally, turmeric has been linked to one report of kidney failure, although the role of turmeric in this case is unclear. A 69-year-old male developed kidney failure related to calcium oxalate deposits in the renal tubules following supplementation with turmeric 2 grams daily for 2 years as an anti-inflammatory for pelvic pain. While turmeric is a source of dietary oxalates, pre-existing health conditions and/or chronic use of antibiotics may have contributed to the course of disease (113343).
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).
