Below is general information about the safety of the known ingredients contained in the product Marrow Plus. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately. Doses of astragalus up to 60 grams daily for up to 4 months have been used without reported adverse effects (32920,33038,95909). ...when used intravenously. Infusion of doses up to 80 grams daily for up to 4 months under the supervision of a medical professional have been used with apparent safety (32811,32812,32828,95909). There is insufficient reliable information available about the safety of astragalus when used topically.
PREGNANCY AND LACTATION:
There is insufficient reliable information in humans.
However, astragaloside, a constituent of astragalus, has maternal and fetal toxic effects in animals (32881). Avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Traditionally, aqueous extract of codonopsis 6-9 grams daily has been used with apparent safety (12).
POSSIBLY UNSAFE ...when used orally in large amounts. Large doses of codonopsis (30-60 grams) have been associated with adverse effects including chest pain, arrhythmia, visual impairment, dizziness, and other conditions (12).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
POSSIBLY SAFE ...when used orally and appropriately. Dong quai has been used with apparent safety in a dose of 4.5 grams daily for 24 weeks, or in combination with other ingredients in doses of up to 150 mg daily for up to 6 months (19552,35797). ...when used intravenously as a 25% solution, in a dose of 200-250 mL daily for up to 20 days (48438,48442,48443,48483).
POSSIBLY UNSAFE ...when used orally in large amounts, long-term. Theoretically, long-term use of large amounts of dong quai could be harmful. Dong quai contains several constituents such as bergapten, safrole, and isosafrole that are considered carcinogenic (7162). There is insufficient reliable information available about the safety of dong quai when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Dong quai has uterine stimulant and relaxant effects (8142); theoretically, it could adversely affect pregnancy. Observational research has found that intake of An-Tai-Yin, an herbal combination product containing dong quai and parsley, during the first trimester is associated with an increased risk of congenital malformations of the musculoskeletal system, connective tissue, and eyes (15129).
LACTATION:
Insufficient reliable information available; avoid use.
POSSIBLY UNSAFE ...when used orally. Fo-ti has been linked to several cases of liver damage (7626,7627,14327,14347,14482,16459,17192,50711,50727,50729) (92892,92895,112231).
CHILDREN: POSSIBLY UNSAFE
when used orally.
Fo-ti has been linked to several cases of liver damage in adults and at least one case in a 5-year-old child (14339,92895).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Fo-ti contains anthraquinone constituents, which can exert a stimulant laxative effect. Bulk-forming or emollient laxatives are preferred in pregnancy (272). Fo-ti has also been linked to several cases of liver damage (7626,7627,14327). There is insufficient reliable information available about the safety of fo-ti when used topically during pregnancy.
LACTATION: POSSIBLY UNSAFE
when used orally.
Anthraquinone constituents can cross into breast milk and might cause loose stools in some breast-fed infants (272). Fo-ti has also been linked to several cases of liver damage (7626,7627,14327). There is insufficient reliable information available about the safety of fo-ti when used topically during lactation.
POSSIBLY SAFE ...when goji fruit preparations are used orally and appropriately, short-term. Goji berry whole fruit, boiled or steamed, has been used with apparent safety at a dose of 15 grams daily for 16 weeks (105489). Other goji berry products have also been used with apparent safety in clinical research, including a specific goji fruit juice (GoChi, FreeLife International) 120 mL daily for 30 days (52532), a goji fruit polysaccharide 300 mg daily for 3 months (92117), and a specific milk-based formulation of goji berry (Lacto-Wolfberry, Nestlé Research Center) for 3 months (52539). There has been some concern about the atropine content of goji; however, most analyses show that levels of atropine in goji berries from China and Thailand are far below potentially toxic levels (52524,94667). There is insufficient reliable information available about the safety of oral use of other parts of the goji plant.
PREGNANCY AND LACTATION:
Insufficient reliable information available.
Some animal research shows that goji fruit may stimulate the uterus (12). However, this has not been reported in humans. Until more is known, avoid using during pregnancy or lactation.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Grapefruit has Generally Recognized as Safe status (GRAS) in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes. A grapefruit seed extract has been safely used in clinical research (5866). In addition, capsules containing grapefruit pectin 15 grams daily have been used in clinical research for up to 16 weeks (2216).
POSSIBLY UNSAFE ...when used orally in excessive amounts. Preliminary population research shows that consuming a quarter or more of a whole grapefruit daily is associated with a 25% to 30% increased risk of postmenopausal breast cancer (14858). Grapefruit juice is thought to reduce estrogen metabolism resulting in increased endogenous estrogen levels. More evidence is needed to validate this finding.
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of using medicinal amounts of grapefruit during pregnancy and lactation; avoid using.
LIKELY SAFE. ..when used orally in food amounts. The flowers, seeds, leaves, and rhizomes of lotus are all edible (95261). There is insufficient reliable information available about the safety of medicinal lotus.
PREGNANCY AND LACTATION:
Insufficient reliable information available on the medicinal use of lotus; avoid using.
POSSIBLY SAFE ...when used orally and appropriately, short term. Rehmannia root extract 4 grams daily or rehmannia leaf extract 800 mg daily has been used with apparent safety for 8 weeks in clinical studies (93660,93662).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when zizyphus fruit is consumed in the amounts typically found in foods.
POSSIBLY SAFE ...when zizyphus fruit or seed is used orally and appropriately, short-term. Zizyphus fruit powder has been used with apparent safety at doses up to 30 grams daily for up to 12 weeks (93317,104507). Zizyphus fruit extract has been used with apparent safety at a dose of 20-40 drops daily for up to 12 weeks (93316). Zizyphus seed extract has been used with apparent safety at a dose of 2 grams daily for 4 weeks (107921). There is insufficient reliable information available about the safety of zizyphus when used topically.
PREGNANCY AND LACTATION: LIKELY SAFE
when zizyphus fruit is consumed in the amounts typically found in foods.
There is insufficient reliable information available about the safety of zizyphus fruit in amounts greater than those found in foods; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Marrow Plus. 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, 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, taking codonopsis root with abiraterone might reduce the levels and therapeutic effects of abiraterone.
Details
Animal research in rats shows that intragastric administration of codonopsis root along with abiraterone every 2 days for 2 weeks seems to increase the clearance of abiraterone and reduce the overall exposure and time to maximum concentration (105912). This interaction has not been reported in humans.
|
Theoretically, codonopsis liquor might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
A small clinical study in adults with coronary heart disease shows that consuming Codonopsis pilosula liquor for 4 weeks inhibits platelet aggregation but does not affect tissue-type plasminogen activator (t-PA) or plasminogen activator inhibitor (PAI) (43888).
|
Theoretically, codonopsis might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
Laboratory and animal research suggest that codonopsis has antidiabetic effects (110743).
|
Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Details
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components (6048,10057,96137). Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin (3526,6048,23310,48439). However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding (96137). Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.
|
Theoretically, dong quai may reduce the effects of estrogens.
Details
|
Dong quai may increase the risk of bleeding when used with warfarin.
Details
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding (3526,6048,23310,48439). In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai (3526).
|
Theoretically, fo-ti might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, taking large amounts of fo-ti might interfere with contraceptive drugs due to competition for estrogen receptors.
Details
|
Theoretically, fo-ti might increase or decrease the levels and clinical effects of drugs metabolized by CYP1A2.
Details
In vitro research suggests that fo-ti might inhibit CYP1A2 (12479,112351). Additionally, in vitro research suggests that the degree of CYP1A2 inhibition depends on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, in an animal study, an aqueous extract of fo-ti inhibited CYP1A2 while an alcoholic extract of fo-ti induced CYP1A2 (92898). Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.
|
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2B6.
Details
Animal research suggests that fo-ti might inhibit CYP2B6 (92898). One in vitro study suggests that the degree of CYP2B6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.
|
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
Animal and in vitro research suggests that fo-ti may inhibit CYP2C19 (12479,92898,112351). An in vitro study suggests that the degree of CYP2C19 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.
|
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2C8.
Details
In vitro research suggests that fo-ti might inhibit CYP2C8 (112351). However, this interaction has not been reported in humans.
|
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C9.
Details
|
Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2D6.
Details
Animal research suggests that fo-ti might inhibit CYP2D6 (92898). Additionally, an in vitro study suggests that the degree of CYP2D6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.
|
Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP3A4.
Details
In vitro research suggests that fo-ti might inhibit CYP3A4 (12479,112351). One in vitro study suggests that the degree of CYP3A4 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this evidence conflicts with animal research suggesting that fo-ti does not inhibit CYP3A4 (92898). This interaction has not been reported in humans.
|
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia and cardiotoxicity when taken with digoxin.
Details
|
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia when taken with diuretic drugs.
Details
|
Theoretically, taking large amounts of fo-ti might interfere with hormone replacement therapy through competition for estrogen receptors.
Details
|
Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.
Details
|
Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of fluid and electrolyte depletion when taken with stimulant laxatives.
Details
|
Theoretically, fo-ti might increase or decrease the levels and clinical effects of sulindac.
Details
Animal research suggests that the type of fo-ti extract might affect the levels of sulindac differently; the raw plant may increase levels, but processed parts may decrease levels (112351). Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.
|
Theoretically, fo-ti might increase the effects and adverse effects of warfarin.
Details
Fo-ti may have stimulant laxative effects and cause diarrhea, especially when the raw or unprocessed fo-ti root is used (5,12,16459,50733,99855). Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Also, fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of warfarin. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery (17192).
|
Theoretically, concomitant use of goji fruit polysaccharides or goji root bark with antidiabetes drugs might have additive effects.
Details
Animal and in vitro research show that goji root bark and fruit polysaccharides might have hypoglycemic effects (7126,92118,94667). However, clinical research has only shown that taking goji fruit polysaccharides with or without antidiabetes drugs modestly reduces postprandial glucose when compared with control, with no reports of hypoglycemia (92117).
|
Theoretically, concomitant use of goji root bark, but not goji fruit, with antihypertensive drugs might have additive effects.
Details
|
Theoretically, goji berry might inhibit CYP2C19 and reduce metabolism of CYP2C19 substrates.
Details
In vitro research shows that goji berry tincture and juice inhibit CYP2C19 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2C19 substrates. However, this has not been reported in humans.
|
Theoretically, goji berry might inhibit CYP2C9 and reduce metabolism of CYP2C9 substrates.
Details
In vitro research shows that goji berry tincture and juice inhibit CYP2C9 enzymes (105486). Additionally, multiple case reports suggest that goji berry concentrated tea and juice inhibit the metabolism of warfarin, a CYP2C9 substrate (7158,105462). Concomitant use with goji may decrease metabolism and increase levels of CYP2C9 substrates.
|
Theoretically, goji berry might inhibit CYP2D6 and reduce metabolism of CYP2D6 substrates.
Details
In vitro research shows that goji berry juice inhibits CYP2D6 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP2D6 substrates. However, this has not been reported in humans.
|
Theoretically, goji berry might inhibit CYP3A4 and reduce metabolism of CYP3A4 substrates.
Details
In vitro research shows that goji berry juice inhibits CYP3A4 enzymes (105486). Concomitant use with goji may decrease metabolism and increase levels of CYP3A4 substrates. However, this has not been reported in humans.
|
Theoretically, goji berry might increase the levels and clinical effects of flecainide.
Details
In one case report, a 75-year-old patient stable on flecainide and warfarin presented to the emergency room with fainting and pleomorphic arrhythmia caused by flecainide toxicity. Flecainide toxicity was attributed to drinking 1-2 glasses of concentrated goji tea daily for 2 weeks. Theoretically, goji may have inhibited the cytochrome P450 2D6 (CYP2D6) metabolism of flecainide (105462).
|
Goji can increase the effects of warfarin and possibly increase the risk of bleeding.
Details
There are at least 5 case reports of increased international normalized ratio (INR) in patients stabilized on warfarin who began drinking goji juice, concentrated goji tea, or goji wine (7158,16529,23896,105462,105487). Goji may inhibit the metabolism of warfarin by cytochrome P450 2C9 (CYP2C9) (7158).
|
Grapefruit juice can decrease blood levels of acebutolol, potentially decreasing the clinical effects of acebutolol.
Details
Clinical research shows that grapefruit juice can modestly decrease acebutolol levels by 7% and reduce peak plasma concentration by 19% by inhibiting organic anion transporting polypeptide (OATP) (17603,18101). The acebutolol half-life is also extended by 1.1 hours when grapefruit juice is consumed concomitantly (18101). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of aliskiren, potentially decreasing the clinical effects of aliskiren.
Details
Clinical research shows that grapefruit juice can decrease aliskiren levels by approximately 60% by inhibiting organic anion transporting polypeptide (OATP) (91428). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of amiodarone, potentially increasing the effects and adverse effects of amiodarone.
Details
|
Grapefruit juice might decrease blood levels of amprenavir, although this is not likely to be clinically significant.
Details
Some clinical research shows that grapefruit juice can slightly decrease amprenavir levels (17673); however, this is probably not clinically significant.
|
Grapefruit juice can increase blood levels of oral artemether, potentially increasing the effects and adverse effects of artemether.
Details
|
Grapefruit juice might increase blood levels of some oral benzodiazepines, potentially increasing the effects and adverse effects of these drugs.
Details
Clinical research shows that grapefruit juice can increase plasma triazolam concentrations. Repeated consumption of grapefruit juice greatly increases triazolam concentrations and prolongs the half-life, probably due to inhibition of cytochrome P450 3A4 (CYP3A4) (7776,22118,22131,22133). Some studies show that grapefruit juice, particularly when taken in large quantities, reduces the clearance and increases the maximum blood levels, area under the plasma concentration curve (AUC), and duration of effect of midazolam. However, there is no effect on intravenous midazolam (4300,10159,11275,17601,22117,22119,16711,91427,95978). Grapefruit juice has also been shown to increase the maximum blood levels and duration of effect of diazepam, but the clinical significance of this is not known (3228). This interaction does not appear to occur with alprazolam (17674).
|
Grapefruit juice can increase blood levels of blonanserin, potentially increasing the effects and adverse effects of blonanserin.
Details
Blonanserin is metabolized primarily by cytochrome P450 3A4 (CYP3A4). A small clinical study shows that taking grapefruit juice along with oral blonanserin increases exposure to blonanserin almost 6-fold due to inhibition of intestinal CYP3A4 by grapefruit juice and prolongs the elimination half-life of blonanserin by 2.2-fold due to inhibition of hepatic CYP3A4 by grapefruit juice (96943).
|
Grapefruit juice can increase blood levels of budesonide, potentially increasing the effects and adverse effects of budesonide.
Details
Budesonide is metabolized by cytochrome P450 3A4 (CYP3A4). A small clinical study shows that taking grapefruit juice along with oral budesonide increases the plasma concentration of budesonide. This effect is attributed to grapefruit-induced inhibition of CYP3A4 in both the colon and small intestine (91425).
|
Grapefruit juice can increase blood levels of buspirone, potentially increasing the effects and adverse effects of buspirone.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of buspirone (3771).
|
Grapefruit juice can decrease the clearance of caffeine, potentially increasing the effects and adverse effects of caffeine.
Details
Clinical research shows that grapefruit juice decreases caffeine clearance (4300).
|
Grapefruit juice can increase blood levels of oral calcium channel blockers, potentially increasing the effects and adverse effects of these drugs.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of amlodipine (523), nifedipine (528,22114), nisoldipine (529), verapamil (7779,8285), felodipine, nimodipine, nicardipine, diltiazem, pranidipine, nitrendipine, and manidipine (524,528,1388,4300,7780,11276,22136,53338,22138,22139) (22140,22141,22142,22143,22147,22148,22149,53367,22158),
This interaction is likely the result of the inhibition of intestinal metabolism of these drugs by CYP3A4 (7779,7780), although some research suggests grapefruit may alter plasma drug levels by reducing the rate of gastric emptying (22167). Consuming grapefruit juice 1 liter daily increases steady state concentrations of verapamil by as much as 50% (8285). However, some references dispute the clinical relevance of the interactions with amlodipine, diltiazem, and verapamil (3230,4300,22159). Other research in healthy individuals suggests plasma levels of felodipine and nifedipine are not affected when given intravenously (22144,22146). There is considerable interindividual variability in the effect of grapefruit juice on drug metabolism, which might account for inconsistent study results (7777,7779,8285). In healthy older adults, the hemodynamic response to felodipine plus grapefruit juice might be influenced by altered autonomic regulation. In older healthy adults, a single dose of grapefruit juice and felodipine enhanced the blood pressure-lowering effects of felodipine. However, after a week of grapefruit juice and felodipine (steady state), the hypotensive activity was reduced, possibly due to compensatory tachycardia (1392). Research indicates it is necessary to withhold grapefruit juice for as long as 3 days to avoid interactions with felodipine and nisoldipine (5068,5069,6453,22145).
|
Grapefruit juice can increase blood levels of carbamazepine, potentially increasing the effects and adverse effects of carbamazepine.
Details
Clinical research shows that grapefruit juice increases absorption and plasma concentrations of carbamazepine (524).
|
Grapefruit juice can increase blood levels of carvedilol, potentially increasing the effects and adverse effects of carvedilol.
Details
Clinical research shows that grapefruit juice increases the bioavailability of a single dose of carvedilol by 16% (5071).
|
Grapefruit juice can decrease blood levels of celiprolol, potentially decreasing the clinical effects of celiprolol.
Details
In human research, taking grapefruit juice within two hours of celiprolol appears to decrease absorption and blood levels of celiprolol by approximately 85% (91421). This interaction is due to grapefruit-induced inhibition of organic anion transporting polypeptide (OATP) (17603,17604,22161). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of cisapride, potentially increasing the effects and adverse effects of cisapride.
Details
|
Theoretically, grapefruit juice might increase blood levels of clomipramine, potentially increasing the effects and adverse effects of clomipramine.
Details
Case reports have shown that clomipramine trough levels increase significantly after the addition of grapefruit juice to the therapeutic regimen (5064).
|
Grapefruit juice can decrease blood levels of the active metabolite of clopidogrel, thereby decreasing the antiplatelet effect of clopidogrel.
Details
Clopidogrel is an antiplatelet prodrug that is metabolized primarily by cytochrome P450 2C19 (CYP2C19) to form the active metabolite. A small clinical study shows that taking grapefruit juice with clopidogrel decreases plasma levels of the active metabolite by more than 80% and impairs the antiplatelet effect of clopidogrel. This effect is possibly due to grapefruit-induced inhibition of CYP2C19 (91419).
|
Theoretically, grapefruit juice might increase blood levels of colchicine, potentially increasing the effects and adverse effects of colchicine.
Details
Colchicine is an alkaloid that undergoes P-glycoprotein (P-gp) mediated drug efflux in the intestines, followed by metabolism by cytochrome P450 3A4 (CYP3A4). There is concern that grapefruit juice will increase the effects and adverse effects of colchicine due to grapefruit-induced inhibition of P-gp and/or CYP3A4. In vitro evidence shows that grapefruit juice increases absorption of colchicine by inhibiting P-gp (94158). A case of acute colchicine toxicity has been reported for an 8-year-old female who drank grapefruit juice while taking high-dose colchicine, long-term (94157). However, one small clinical study in healthy adults shows that drinking grapefruit juice 240 mL twice daily for 4 days does not affect the bioavailability or adverse effects of a single dose of colchicine 0.6 mg taken on the fourth day (35762).
|
Grapefruit juice can increase blood levels of oral cyclosporine, potentially increasing the effects and adverse effects of cyclosporine.
Details
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP1A2.
Details
In vitro research suggests that grapefruit juice might inhibit CYP1A2 enzymes (12479). So far, this interaction has not been reported in humans.
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP2C19.
Details
In vitro research suggests that grapefruit juice might inhibit CYP2C19 enzymes (12479). Also, a small clinical study shows that taking grapefruit juice with clopidogrel, an antiplatelet prodrug that is metabolized primarily by CYP2C19, decreases plasma levels of the active metabolite and impairs the antiplatelet effect of clopidogrel. This effect is likely due to grapefruit-induced inhibition of CYP2C19 (91419).
|
Theoretically, grapefruit juice might increase levels of drugs metabolized by CYP2C9.
Details
In vitro research suggests that grapefruit juice might inhibit CYP2C9 enzymes (12479). So far, this interaction has not been reported in humans.
|
Grapefruit juice can increase levels of drugs metabolized by CYP3A4.

Clinical research shows that grapefruit juice can inhibit CYP3A4 metabolism of drugs, causing increased drug levels and potentially increasing the risk of adverse effects (3227,3774,8283,8285,8286,22129,91427,104190). When taken orally, effects of grapefruit juice on CYP3A4 levels appear to last at least 48 hours (91427). Grapefruit's ability to inhibit CYP3A4 has even been harnessed to intentionally increase levels of venetoclax, which is metabolized by CYP3A4, in an elderly patient with acute myeloid leukemia who could not afford full dose venetoclax. The lower dose of venetoclax in combination with grapefruit juice resulted in serum levels of venetoclax in the therapeutic reference range of full dose venetoclax and positive treatment outcomes for the patient (112287).
Professional consensus recommends the consideration of patient age, existing medical conditions, additional medications, and the potential for additive adverse effects when evaluating the risks of concomitant use of grapefruit juice with any medication metabolized by CYP3A4. While all patients are at risk for interactions with grapefruit juice consumption, patients older than 70 years of age and those taking multiple medications are at the greatest risk for a serious or fatal interaction with grapefruit juice (95970,95972). |
Grapefruit juice can increase blood levels of dapoxetine, potentially increasing the effects and adverse effects of dapoxetine.
Details
Pharmacokinetic research shows that drinking grapefruit juice 250 mL prior to taking dapoxetine 60 mg can increase the maximum plasma concentration of dapoxetine by 80% and prolong the elimination half-life by 43%. This effect is attributed to the inhibition of both intestinal and hepatic cytochrome P450 3A4 (CYP3A4) by grapefruit (95975).
|
Grapefruit juice can increase blood levels of dextromethorphan, potentially increasing the effects and adverse effects of dextromethorphan.
Details
Clinical research shows that grapefruit juice can inhibit cytochrome P450 3A4 (CYP3A4) metabolism, causing increased dextromethorphan levels (11362).
|
Grapefruit juice can increase blood levels of erythromycin, potentially increasing the effects and adverse effects of erythromycin.
Details
Clinical research shows that concomitant use of erythromycin with grapefruit can inhibit cytochrome P450 3A4 (CYP3A4) metabolism of erythromycin, increasing plasma concentrations of erythromycin by 35% (8286).
|
Grapefruit juice can increase blood levels of estrogens, potentially increasing the effects and adverse effects of estrogens.
Details
Clinical research shows that grapefruit increases the levels of endogenous and exogenous estrogens by inhibiting cytochrome P450 3A4 (CYP3A4) enzymes (525,526,14858). Grapefruit juice increases exogenously administered 17-beta-estradiol by about 20% in females without ovaries and ethinyl-estradiol in healthy females (525,526,22160).
|
Grapefruit juice can decrease blood levels of etoposide, potentially decreasing the clinical effects of etoposide.
Details
Clinical research shows that grapefruit juice decreases the absorption and plasma concentrations of etoposide. There is some evidence that grapefruit juice co-administered with oral etoposide can reduce levels of etoposide by about 26% (8744). Grapefruit juice seems to inhibit organic anion transporting polypeptide (OATP), which is a drug transporter in the gut, liver, and kidney (7046,17603,17604). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of fexofenadine, thereby decreasing the clinical effects of fexofenadine.
Details
Clinical research shows that grapefruit juice can significantly decrease oral absorption and blood levels of fexofenadine. In one study, consuming a drink containing grapefruit juice 25% decreased bioavailability of fexofenadine by about 24%. Consuming a full-strength grapefruit juice drink reduced bioavailability by 67% (7046). In another study, consuming grapefruit juice 300 mL decreased fexofenadine levels by 42%. Consuming 1200 mL of grapefruit juice reduced levels by 64% (17602). Similarly, drinking grapefruit juice 240 mL decreased the oral bioavailability of fexofenadine by 25% in another pharmacokinetic study (112288). Fexofenadine manufacturer data indicates that concomitant administration of grapefruit juice and fexofenadine results in larger wheal and flare sizes in research models. This suggests that grapefruit also reduces the clinical response to fexofenadine (17603).
Grapefruit juice seems to inhibit organic anion transporting polypeptide (OATP), which is a drug transporter in the gut, liver, and kidney (7046,17603,17604,22161). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604). |
Grapefruit juice can increase blood levels of fluvoxamine, potentially increasing the effects and adverse effects of fluvoxamine.
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases fluvoxamine levels and peak concentration (17675).
|
Grapefruit juice can increase blood levels of halofantrine, potentially increasing the effects and adverse effects of halofantrine.
Details
Clinical research shows that grapefruit juice inhibits cytochrome P450 3A4 (CYP3A4) metabolism, which increases halofantrine levels and peak concentration, as well as a marker of ventricular tachyarrhythmia potential (22129).
|
Grapefruit juice can increase blood levels of statins that are metabolized by cytochrome P450 3A4 (CYP3A4), potentially increasing the effects and adverse effects of these statins. Additionally, grapefruit juice might interfere with the bioavailability of statins that are substrates of organic anion transporting polypeptides (OATP).
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases absorption and plasma concentrations of statins that are metabolized by CYP3A4. These include lovastatin (527,11274), simvastatin (3774,7782,22127), and atorvastatin (3227,12179,22126). Keep in mind that there is considerable variability in the effect of grapefruit juice on drug metabolism, so individual patient response is difficult to predict (7777,7781).
Some statins, including pravastatin, fluvastatin, pitavastatin, and rosuvastatin, are not metabolized by CYP3A4. However, grapefruit juice might still affect the bioavailability of these statins. These statins are substrates of OATP. Grapefruit juice can inhibit OATP. Therefore, grapefruit juice may reduce the bioavailability or increase drug levels of these statins depending on the type of OATP. However, grapefruit juice affects OATP for only a short time. Therefore, separating drug administration by at least 4 hours is likely to avoid this interaction (3227,12179,17601,22126,91420). |
Grapefruit juice can interfere with itraconazole absorption, although the clinical significance of this interaction is unclear.
Details
|
Grapefruit juice can decrease blood levels of levothyroxine, potentially decreasing the effectiveness of levothyroxine.
Details
Clinical research shows that grapefruit juice modestly decreases levothyroxine levels by 11% by inhibiting organic anion transporting polypeptide (OATP) (17604,22163). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can decrease blood levels of the active metabolite of losartan, potentially decreasing the clinical effects of losartan.
Details
Losartan is an inactive prodrug which must be metabolized to its active form, E-3174, to be effective. In one human study, grapefruit juice reduced losartan metabolism, increased losartan AUC, and reduced the AUC of the major active losartan metabolite, E-3174 (1391).
|
Grapefruit juice can increase blood levels of methadone, potentially increasing the effects and adverse effects of methadone.
Details
Clinical research shows that grapefruit juice inhibits the metabolism of methadone, increasing methadone levels and peak concentrations (17676). In one case, a 51-year-old male taking methadone 90 mg daily and no other medications was found unresponsive. The patient reported drinking grapefruit juice 500 mL daily for 3 days prior to the event. Methadone is a substrate of cytochrome P450 3A4 (CYP3A4), and grapefruit juice-induced inhibition of CYP3A4 is the likely cause of this interaction (102056).
|
Grapefruit juice can increase blood levels of methylprednisolone, potentially increasing the effects and adverse effects of methylprednisolone.
Details
Clinical research shows that grapefruit juice can increase the plasma concentration of orally administered methylprednisolone. Grapefruit juice 200 mL three times daily given with methylprednisolone 16 mg increased methylprednisolone half-life by 35%, peak plasma concentration by 27%, and total area under the curve by 75% (3123).
|
Grapefruit juice might decrease blood levels of nadolol, potentially decreasing the clinical effects of nadolol.
Details
Nadolol is a substrate of organic anion transporting polypeptide 1A2 (OATP1A2) (17603,17604,22161). Some research shows that grapefruit juice and its constituent naringin can inhibit organic anion transporting polypeptides (OATP), which can reduce the bioavailability of OATP substrates (17603,17604,22161,91427). However, preliminary clinical research shows that grapefruit juice containing a low amount of naringin does not significantly affect levels of nadolol (91422). It is not known if grapefruit juice containing higher amounts of naringin reduces the bioavailability of nadolol.
|
Grapefruit juice can increase blood levels of nilotinib, potentially increasing the effects and adverse effects of nilotinib.
Details
Clinical research shows that grapefruit juice inhibits metabolism and increases absorption of nilotinib. Grapefruit juice increases nilotinib levels by 29% and peak concentration by 60% (17677).
|
Grapefruit juice can decrease levels of drugs that are substrates of OATP.
Details
In vitro and clinical research show that consuming grapefruit juice inhibits OATP, which reduces the bioavailability of oral drugs that are substrates of OATP. Various clinical studies have shown reduced absorption of OATP substrates when taken with grapefruit, including fexofenadine, acebutolol, aliskiren, celiprolol, levothyroxine, nadolol, and pitavastatin (17603,17604,18101,22126,22134,22161,22163,91420,91427,91428,112288). Grapefruit juice is thought to affect OATP for only a short time. Therefore, separating drug administration and consumption of grapefruit by at least 4 hours is likely to prevent this interaction (17603,17604).
|
Grapefruit juice can increase blood levels of oxycodone, potentially increasing the effects and adverse effects of oxycodone.
Details
Oxycodone is metabolized by both cytochrome P450 3A4 (CYP3A4) and cytochrome P450 2D6 (CYP2D6). A small clinical study shows that grapefruit juice can increase plasma levels of oral oxycodone about 1.7-fold by inhibiting CYP3A4. While the analgesic effects of oxycodone do not seem to be affected, taking grapefruit juice along with oxycodone may theoretically increase the adverse effects of oxycodone (91423).
|
Grapefruit juice does not seem to affect renal P-glycoprotein (P-gp). Theoretically, it might inhibit intestinal P-gp, but evidence is conflicting.
Details
While most in vitro research shows that grapefruit products inhibit P-gp, (1390,11270,11278,11362,95976), research in humans is less clear. Two small clinical studies in healthy adults using digoxin as a probe substrate show that grapefruit juice does not inhibit P-gp in the kidneys (11277,11282). It is unclear whether this applies to intestinal P-gp, for which digoxin is not considered to be a sensitive probe (105568). Grapefruit juice has been shown to reduce levels of fexofenadine (7046,17602,112288), and increase levels of quinidine (5067,22121). However, as both of these drugs are also substrates of other enzymes and transporters, it is unclear what role, if any, intestinal P-gp has in these findings.
|
Grapefruit juice can increase blood levels of pitavastatin, potentially increasing the effects and adverse effects of pitavastatin.
Details
Pharmacokinetic research shows that taking grapefruit juice with pitavastatin 2-4 mg can increase blood levels of pitavastatin by 13% to 14%. Unlike simvastatin and atorvastatin, pitavastatin is not significantly metabolized by cytochrome P450 3A4 (CYP3A4) enzymes. Grapefruit juice appears to increase levels of pitavastatin by inhibiting its uptake by organic anion transporting polypeptide 1B1 (OATP1B1) into hepatocytes for metabolism and clearance from the body (22126,91420). Grapefruit juice seems to increase levels of pitavastatin to a greater degree in patients homozygous for a specific polymorphism (388A>G) in the OATP1B1 gene compared to those heterozygous for this polymorphism (91420).
|
Grapefruit juice can decrease blood levels of the active metabolite of prasugrel, thereby decreasing the antiplatelet effect of prasugrel.
Details
Prasugrel is a prodrug that is metabolized by cytochrome P450 3A4 (CYP3A4) into its active metabolite. A small pharmacokinetic study in healthy volunteers shows that drinking grapefruit juice 200 mL three times daily for 4 days and taking a single dose of prasugrel 10 mg with an additional 200 mL of grapefruit juice on day 3, results in a 49% lower peak plasma level and a 26% lower overall plasma exposure to the active metabolite when compared with drinking water. However, despite the reduced exposure, platelet aggregation seems to be reduced by an average of only 5% (105567). The clinical significance of this interaction is unclear.
|
Grapefruit juice can increase blood levels of praziquantel, potentially increasing the effects and adverse effects of praziquantel.
Details
Clinical research shows that grapefruit juice can inhibit cytochrome P450 3A4 (CYP3A4) metabolism of praziquantel. Plasma concentrations of praziquantel can increase by as much as 160% when administered with 250 mL of commercially available grapefruit juice (8282).
|
Grapefruit juice may increase blood levels of primaquine, potentially increasing the effects and adverse effects of primaquine.
Details
Clinical research shows that grapefruit juice increases the bioavailability of primaquine by approximately 20% (22130). The clinical significance of this interaction is not clear.
|
Grapefruit or grapefruit juice, especially if consumed in large amounts, can cause additive QT interval prolongation when taken with QT interval-prolonging drugs, potentially increasing the risk of ventricular arrhythmias.
Details
Clinical research in healthy volunteers shows that drinking 6 liters of grapefruit juice over 6 hours prolonged the QTc by a peak amount of 14 milliseconds (ms). This prolongation was similar to the QT prolongation caused by the drug moxifloxacin. In individuals with long QT syndrome, a smaller dose of grapefruit juice, 1.5 liters, resulted in a greater peak QTc prolongation of about 30 ms (100249). The effect of smaller quantities of grapefruit juice on the QT interval is unclear.
|
Grapefruit juice may increase blood levels of quetiapine, increasing the effects and adverse effects of quetiapine.
Details
Quetiapine is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4 (3227,3774,8283,8285,8286,22129,91427,104190). In one case report, a healthy 28-year-old female with bipolar disorder stabilized on quetiapine 800 mg daily presented with quetiapine toxicity considered to be related to consuming a gallon of grapefruit juice over the past 24 hours (108848).
|

|
Grapefruit juice may slightly increase blood levels of sunitinib, potentially increasing the effects and adverse effects of sunitinib.
Details
Sunitinib is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit and grapefruit juice can inhibit CYP3A4 and increase levels of some drugs metabolized by this enzyme. One small clinical study shows that drinking 200 mL of grapefruit juice three times daily can increase the bioavailability of sunitinib by 11% (91429). While this effect is unlikely to be clinically significant, patients should use caution when using grapefruit along with sunitinib. Dose adjustments may be necessary.
|
Grapefruit juice can increase blood levels of tacrolimus, potentially increasing the effects and adverse effects of tacrolimus.
Details
Clinical research shows that drinking grapefruit juice 200 mL daily while taking tacrolimus 3 mg daily increases the trough blood concentration of tacrolimus by approximately 3-fold in patients with connective tissue diseases (95974). A single case has also reported a 10-fold increase in tacrolimus trough levels after the ingestion of grapefruit juice over 3 days (22122). This effect is attributed to the inhibition of cytochrome P450 3A4 (CYP3A4) by grapefruit (95974).
|
Theoretically, grapefruit juice might increase blood levels of tadalafil, potentially increasing the effects and adverse effects of tadalafil.
Details
Animal research shows that grapefruit juice increases tadalafil serum concentrations and overall exposure, likely through inhibition of cytochrome P450 3A4 enzymes (104189).
|
Grapefruit juice might decrease blood levels of talinolol, potentially decreasing the clinical effects of talinolol.
Details

Details
|
Grapefruit juice can decrease blood levels of theophylline, potentially decreasing the effectiveness of theophylline.
Details

|
Grapefruit juice can increase blood levels of ticagrelor, thereby increasing the effects and adverse effects of ticagrelor.
Details
Ticagrelor is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4. A small clinical study shows that taking grapefruit juice with ticagrelor increases blood levels of ticagrelor more than two-fold and increases the antiplatelet activity of ticagrelor (91418).
|
Grapefruit juice can increase blood levels of tolvaptan, potentially increasing the effects and adverse effects of tolvaptan.
Details
Tolvaptan is metabolized by cytochrome P450 3A4 (CYP3A4). Grapefruit can inhibit CYP3A4. A small clinical study shows that grapefruit juice can increase the bioavailability and blood levels of tolvaptan by approximately 1.6-fold for up to 16 hours (91426).
|
Theoretically, drinking large amounts of grapefruit juice might increase the effects and adverse effects of warfarin.
Details
In one case report, a patient experienced significantly increased international normalized ratio (INR) associated with consumption of 50 ounces of grapefruit juice daily (12061). However, smaller amounts of grapefruit juice might not be a problem. In a small clinical trial, consumption of 24 ounces of grapefruit juice daily for one week had no effect on INR in males treated with warfarin (12063).
|
Theoretically, concurrent use of lotus with other antiplatelet drugs might reduce platelet aggregation and increase the risk of bleeding.
Details
|
Theoretically, lotus might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Details
Animal research shows that the ethanolic extract of lotus reduces blood glucose levels and potentiates the effects of injected insulin (60053). Monitor blood glucose levels closely. Dose adjustments might be necessary.
|
Theoretically, taking lotus concomitantly with pentobarbital might increase sedation.
Details
Animal research shows that lotus extract increases pentobarbitone-induced sleeping time (60051). It is not known if this occurs in humans or if this effect occurs with other barbiturates or sedatives.

Below is general information about the adverse effects of the known ingredients contained in the product Marrow Plus. 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 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).
Neurologic/CNS ...Rapid intravenous administration of astragalus has resulted in temporary dizziness (32812).
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, codonopsis seems to be well tolerated when used appropriately; however, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Allergic reactions such as anaphylaxis.
Cardiovascular ...Orally, very large doses of codonopsis (30-60 grams) may cause chest pain or arrhythmia (12).
Gastrointestinal ...Orally, very large doses of codonopsis (30-60 grams) may cause throat pain and loss of voice (12).
Immunologic ...Orally, codonopsis can cause allergic reactions including anaphylaxis and urticaria. In one case report, an 18-year-old male developed anaphylaxis after ingesting codonopsis roots. In an oral re-challenge test, he developed anaphylaxis and urticaria again 30 minutes after consuming 20 grams of codonopsis root. Although codonopsis is in the same family as mugwort, the patient did not appear to be sensitized to mugwort pollen (100060).
Neurologic/CNS ...Orally, very large doses of codonopsis (30-60 grams) may cause vision problems, dizziness, loss of balance, leg spasms, and confusion (12).
General
...Orally, dong quai is generally well-tolerated.
Most Common Adverse Effects:
Orally: Burping and flatulence.
Intravenously: Headache.
Cardiovascular ...Orally, dong quai might cause hypertension; according to one case report, a parent and breastfed infant experienced hypertension (195/85 mmHg and 115/69 mmHg, respectively) after the parent consumed a soup containing dong quai root (48428).
Dermatologic ...Dong quai contains psoralens that may cause photosensitivity and photodermatitis (10054,10057,48461).
Endocrine ...In a case report, a male developed gynecomastia after ingesting dong quai tablets (48504).
Gastrointestinal ...Orally, burping and gas may occur with dong quai (738).
Hematologic ...In one 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 three days after taking a phytoestrogen preparation containing dong quai 100 mg, black cohosh 250 mg, wild Mexican yam 276 mg, and red clover 250 mg (13155). It is unclear if dong quai contributed to this event.
Neurologic/CNS ...Dong quai given orally or by injection may be associated with headache (738,48438).
Oncologic ...Dong quai contains constituents that are carcinogenic; however, whether these constituents are present in concentrations large enough to cause cancer with long-term or high-dose use is unknown (7162).
Pulmonary/Respiratory ...A pharmacist experienced allergic asthma and rhinitis after occupational exposure to dong quai and other herbs (48435).
General
...Orally, fo-ti may be unsafe.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, nausea, and vomiting with use of unprocessed fo-ti.
Serious Adverse Effects (Rare):
Orally: Hepatotoxicity with processed or unprocessed fo-ti.
Dermatologic ...Orally, one case of a fine maculopapular rash was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if the rash was due to fo-ti or other ingredients in the herbal product.
Gastrointestinal ...Orally, unprocessed fo-ti may cause diarrhea, abdominal pain, nausea, and vomiting (12,50733).
Hematologic ...Orally, one case of mild eosinophilia was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if this reaction was due to fo-ti or other ingredients in the herbal product. A case of agranulocytosis was reported in a 65-year-old female taking fo-ti 30 grams/day for 17 days. The patient recovered gradually following a 15-day hospitalization, which included treatment with intravenous steroids and granulocyte colony-stimulating factor (112231).
Hepatic
...Orally, cases of liver damage due to both processed and unprocessed fo-ti have been well documented in the medical literature.
(7626,7627,14327,14339,14347,14482,16459,17192,50711,50726)(50727,50729,92892,92895,112231).
In a systematic review, around 450 cases of hepatitis associated with fo-ti were identified. These cases occurred in patients 5-78 years of age. Liver damage occurred at a wide range of doses, formulations, and durations of intake. The type of liver injury ranged from hepatocellular, to cholestatic, or mixed. Outcomes ranged from full recovery to cirrhosis, liver transplantation, and/or death. The evidence suggests that when the daily fo-ti dose is less than 12 grams, the median time to occurrence of liver damage is 60 days. When the daily fo-ti dose is more than 12 grams, the median time to liver damage is 30 days (92895). Presenting signs and symptoms may include jaundice, abdominal pain, nausea, fatigue, loss of appetite, dark urine, myalgias, and elevations in liver function tests (LFTs), ferritin, transferrin, prothrombin time, and INR (17192,92892). Other manifestations may include fever, skin rash, thrombocytopenia, pancytopenia, and arthralgias. Symptoms and increased LFTs usually seem to resolve within a month after discontinuing fo-ti (7626,7627,14339,14347,14482,16459). In one case series, liver enzymes began to normalize 48 hours after discontinuation of fo-ti and treatment with S-adenosylmethionine, compound glycyrrhizin injection, polyene phosphatidylcholine, and reduced glutathione. All patients were eventually discharged home in stable condition (92892). Rechallenge with fo-ti should not be attempted. A patient who had recovered from hepatitis associated with fo-ti use presented with myalgias and markedly elevated LFTs after a single dose of the herb (17192).
It is thought that this idiosyncratic reaction leading to liver damage is at least partially related to genetic polymorphisms. Cytochrome P450 1A2 (CYP1A2) is the predominant enzyme involved in biotransformation of emodin, a constituent of fo-ti thought to play a role in liver damage. In one genetic study, the frequency of CYP1A2*1C mutation in fo-ti induced drug-induced liver injury patients was 46.5%, which is significantly higher than the 27.9% frequency of liver injury reported in healthy patients without the mutation. Patients with a CYP1A2*1C mutation may have decreased activity of the CYP1A2 enzyme, which could inhibit the metabolism of fo-ti, causing an accumulation of toxic substances (92897).
General
...Orally, goji fruit seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions including anaphylaxis.
Dermatologic ...A case of photosensitivity secondary to consumption of goji berries has been reported. The patient presented with a pruriginous eruption that had lasted for 2 weeks. The patient had been taking goji berries for 5 months and cat's claw for 3 months. Upon testing, it was revealed that the patient tested positive to goji berries in a photoprovocation test, but not to cat's claw (40263).
Hepatic ...Orally, consumption of goji berries has been associated with a single case report of autoimmune hepatitis (52541). A case of acute hepatitis has also been reported in a female who consumed 2 ounces of a specific combination product (Euforia, Nuverus International) containing goji berry, pomegranate, curcumin, green tea, noni, acai berry, aloe vera, blueberry, resveratrol, mangosteen, and black seed, daily for one month. It is unclear whether the liver injury was caused by goji berry, other ingredients, or the combination (90125).
Immunologic ...Several cases of allergic reactions secondary to consumption of goji berries have been reported. Symptoms included facial angioedema with dyspnea, pharyngeal itching, itching in the mouth, ears, and axilla, labial angioedema, and perioral skin rash (92116). Anaphylaxis has also been reported (52538).
General
...Orally, grapefruit and grapefruit juice are generally well tolerated.
Serious Adverse Effects (Rare):
Orally: Allergic reactions in sensitive individuals have been reported. When large quantities are consumed, arrhythmias, mineralocorticoid excess, QT prolongation, and pseudohyperaldosteronism have been reported. There is also some concern for increased breast cancer risk with grapefruit consumption.
Cardiovascular ...Orally, consumption of pink grapefruit juice 1000 mL can cause QT prolongation and cause arrhythmias in healthy patients and worsen arrhythmias in cardiomyopathy patients (13031,91424).
Endocrine ...Orally, high doses of grapefruit juice have been observed to cause pseudohyperaldosteronism and mineralocorticoid excess (53340,53346).
Gastrointestinal ...In a case report, grapefruit juice held against the teeth resulted in enamel and tooth surface loss (53368).
Immunologic ...Orally, grapefruit can cause allergic sensitization characterized by eosinophilic gastroenteritis, urticaria, and generalized pruritus (53351,53360).
Oncologic ...Preliminary population research shows that postmenopausal adults who consume a quarter or more of a whole grapefruit daily have a 25% to 30% increased risk of developing breast cancer (14858). Grapefruit is a potent inhibitor of cytochrome P450 3A4, which metabolizes estrogen. Consuming large amounts of grapefruit might significantly increase endogenous estrogen levels and therefore increase the risk of breast cancer. More evidence is needed to validate these findings. Until more is known, advise patients to consume grapefruit in moderation.
Renal ...In population research, consumption of 240 mL/day of grapefruit juice is associated with an increased risk of kidney stones (4216,53372).
General ...Orally, adverse effects to lotus seem to be rare when taken in medicinal amounts; however, a thorough safety evaluation has not been conducted.
Immunologic ...Orally and topically, lotus root can cause allergic reactions such as urticaria and contact dermatitis. In a case report, a 6-year-old female developed urticaria after ingesting lotus root. She had also developed contact dermatitis on body areas that had been in contact with the lotus root (99738).
General ...Orally, rehmannia seems to be well tolerated.
General ...Orally, zizyphus fruit extract and powder seem to be well tolerated.
Gastrointestinal ...Orally, zizyphus fruit extract was associated with three cases of mild diarrhea in newborn infants (93306). Zizyphus seed extract was associated with one case of dry mouth and one case of increased bowel movements in a small clinical study (107921).
Neurologic/CNS ...Orally, zizyphus seed extract was associated with two cases of headache in a small clinical study (107921).
