• Urine drug tests. Drinking water with goldenseal or adding goldenseal tea to urine does not appear to cause a false negative urine drug screen for amphetamines, barbiturates, benzodiazepines, cocaine, opiates, phencyclidine, or tetrahydrocannabinol (THC). Details: Goldenseal is often promoted to mask illicit drugs in the urine, but drinking one gallon of water with goldenseal or adding goldenseal tea to urine samples does not seem to cause a false negative immunoassay (EMIT and TDx) for cocaine, amphetamines, barbiturates, benzodiazepines, or opiates. It also does not produce a false negative for Microgenics CEDIA DAU assays for amphetamines, barbiturates, benzodiazepines, cocaine, opiates, phencyclidine, or THC (260,261,52599). Although adding goldenseal tea to urine samples at 15 grams per liter may produce a false-negative EMIT reading for the presence of THC, the adulteration is obvious due to a brownish color in the urine (52599). Some people also claim that goldenseal can cause a false positive on a drug screen. However, goldenseal does not seem to cause false positives for the fluorescent polarization immunoassay (FPIA) or thin-layer chromatography (TLC) assays for amphetamines, opiates, cocaine, methadone, or their metabolites (2590).

• ACE inhibitor-induced cough. It is unclear if oral marshmallow root is beneficial in patients with cough due to ACE inhibitors. Details: A small clinical study in patients with ACE inhibitor-induced cough shows that taking marshmallow root 40 mg (20 drops) three times daily for 4 weeks improves cough when compared to baseline (62027). The validity of this finding is limited by the lack of a control group.
• Atopic dermatitis (eczema). It is unclear if topical marshmallow is beneficial in children with eczema. Details: A very small clinical study in children ages 3 months to 12 years with a recent diagnosis of mild to moderate eczema shows that applying a marshmallow 1% ointment twice daily for 1 week and then three times weekly for 3 weeks seems to reduce symptoms, as measured on the SCORing Atopic Dermatitis (SCORAD) scale, when compared with applying hydrocortisone 1% ointment (105437). This finding is limited by the large number of drop-outs due to non-compliance, most of which were in the marshmallow group.
• Breast engorgement. It is unclear if topical marshmallow is beneficial in women with this condition. Details: A small clinical study in breastfeeding women with breast engorgement shows that applying a compress containing 40-50 mL of a solution made from marshmallow leaves and stems 3 times daily for 2 days in conjunction with standard treatment improves patient-reported breast engorgement scores when compared with standard treatment alone.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.  Details Goldenseal contains berberine. In vitro and animal research shows that berberine can inhibit platelet aggregation (33660,33694). However, this effect has not been reported in humans.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase the risk of hypoglycemia when used with antidiabetes drugs.  Details Goldenseal contains berberine. Clinical research shows that berberine can lower blood glucose levels (20579,34247,34265,34282). However, this effect has not been reported with goldenseal.

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase the risk of hypotension when taken with antihypertensive drugs.  Details Goldenseal contains berberine. Animal research shows that berberine can have hypotensive effects (33692,34308). Also, an analysis of clinical research shows that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone (91956). However, this effect has not been reported with goldenseal.

CNS DEPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase the sedative effects of CNS depressants.  Details Goldenseal contains berberine. Animal research shows that berberine can have sedative effects (13519,33650,33664,33692). However, this effect has not been reported in humans.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2C9.  Details In vitro research shows that goldenseal root extract can modestly inhibit CYP2C9. This effect may be due to its alkaloid constituents, hydrastine and berberine (21117). However, this effect has not been reported in humans.

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = B Goldenseal might increase serum levels of drugs metabolized by CYP2D6.  Details Clinical and in vitro research shows that goldenseal can significantly inhibit CYP2D6 enzymes, potentially increasing levels of drugs metabolized by CYP2D6 (13536,16848,35907).

CYTOCHROME P450 2E1 (CYP2E1) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase serum levels of drugs metabolized by CYP2E1.  Details In vitro research shows that goldenseal root extract can inhibit the activity of CYP2E1 (94140). However, this effect has not been reported in humans.

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Goldenseal might increase serum levels of drugs metabolized by CYP3A4.  Details Most clinical and in vitro research shows that goldenseal inhibits CYP3A4 enzyme activity and increases serum levels of CYP3A4 substrates, such as midazolam (6450,13536,21117,91740). However, in one small clinical study, goldenseal did not affect the levels of indinavir, a CYP3A4 substrate, in healthy volunteers (10690,93578). This is likely due to the fact that indinavir has a high oral bioavailability, making it an inadequate probe for CYP3A4 interactions (13536,91740).

DEXTROMETHORPHAN (Robitussin DM, others) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase serum levels of dextromethorphan.  Details Goldenseal contains berberine. A small clinical study shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan (34279).

DIGOXIN (Lanoxin) Interaction Rating = Moderate Be cautious with this combination. Severity = Mild •  Occurrence = Probable •  Level of Evidence = B Goldenseal might increase serum levels of digoxin, although this effect is unlikely to be clinically significant.  Details Clinical research shows that goldenseal modestly increases digoxin peak levels by about 14% in healthy volunteers. However, goldenseal does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC) (15132). This suggests that goldenseal does not cause a clinically significant interaction with digoxin. Digoxin is a P-glycoprotein substrate. Some evidence suggests that goldenseal constituents might affect P-glycoprotein; however, it is unclear whether these constituents inhibit or induce P-glycoprotein.

LOSARTAN (Cozaar) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might decrease the conversion of losartan to its active form.  Details Goldenseal contains berberine. A small clinical study shows that berberine inhibits cytochrome P450 2C9 (CYP2C9) activity and reduces the metabolism of losartan (34279). However, this effect has not been reported with goldenseal.

METFORMIN (Glucophage) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might reduce blood levels of metformin.  Details In vitro research shows that goldenseal extract decreases the bioavailability of metformin, likely by interfering with transport, intestinal permeability, or other processes involved in metformin absorption. It is unclear which, if any, of metformin's transporters are inhibited by goldenseal. Goldenseal does not appear to alter the clearance or half-life of metformin (105764).

OSELTAMIVIR (Tamiflu) Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might reduce the therapeutic effects of oseltamivir by decreasing its conversion to its active form.  Details In vitro evidence suggests that goldenseal reduces the formation of the active compound from the prodrug oseltamivir (105765). The mechanism of action and clinical relevance is unclear.

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Mild •  Occurrence = Probable •  Level of Evidence = B Theoretically, goldenseal might increase or decrease serum levels of P-glycoprotein (P-gp) substrates.  Details There is conflicting evidence about the effect of goldenseal on P-gp. In vitro research suggests that berberine, a constituent of goldenseal, modestly inhibits P-gp efflux. Other evidence suggests that berberine induces P-gp. In healthy volunteers, goldenseal modestly increases peak levels of the P-gp substrate digoxin by about 14%. However, it does not seem to affect other pharmacokinetic parameters such as area under the curve (AUC) (15132). This suggests that goldenseal is not a potent inhibitor of P-gp-mediated drug efflux. Until more is known, goldenseal should be used cautiously with P-gp substrates.

PENTOBARBITAL (Nembutal) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase the sedative effects of pentobarbital.  Details Animal research shows that berberine, a constituent of goldenseal, can prolong pentobarbital-induced sleeping time (13519). However, this effect has not been reported with goldenseal.

TACROLIMUS (Prograf) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, goldenseal might increase serum levels of tacrolimus.  Details Goldenseal contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of tacrolimus dosing to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL (91954).

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, marshmallow flower might have antiplatelet effects.  Details Animal research suggests that marshmallow flower extract has antiplatelet effects (92846). However, the root and leaf of marshmallow, not the flower, are the plant parts most commonly found in dietary supplements. Theoretically, use of marshmallow flower with anticoagulant/antiplatelet drugs can have additive effects, and might increase the risk for bleeding in some patients.

LITHIUM Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Theoretically, due to potential diuretic effects, marshmallow might reduce excretion and increase levels of lithium.  Details Marshmallow is thought to have diuretic properties. To avoid lithium toxicity, the dose of lithium might need to be decreased when used with marshmallow.

ORAL DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, mucilage in marshmallow might impair absorption of oral drugs.  Details Marshmallow contains mucilage which can affect oral drug absorption (1,11,12,19). To avoid changes in absorption, take marshmallow 30-60 minutes after oral medications.

ASPIRIN Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, meadowsweet might have an additive effect with other salicylate-containing drugs, such as aspirin.  Details Meadowsweet contains salicin, a plant salicylate; however, salicin doesn't seem to have the antiplatelet effects of aspirin (12).

CHOLINE MAGNESIUM TRISALICYLATE (Trilisate) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, meadowsweet might have an additive effect with other salicylate-containing drugs, such as choline magnesium trisalicylate (12).  Details Meadowsweet contains salicin, a plant salicylate (12).

SALSALATE (Disalcid) Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, meadowsweet might have an additive effect with other salicylate-containing drugs such as salsalate (12).  Details Meadowsweet contains salicin, a plant salicylate (12).
