HelloPharmacist Scorecard of Queen of the Meadow by Herbal Terra

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use

Theoretically, drugs that induce CYP3A4 might increase the conversion of PAs to toxic metabolites. Some drugs that induce CYP3A4 include carbamazepine (Tegretol), phenobarbital, phenytoin (Dilantin), rifampin, rifabutin (Mycobutin), and others.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Hemp agrimony contains hepatotoxic pyrrolizidine alkaloids (PA). Theoretically, using hemp agrimony with hepatotoxic drugs might have additive adverse effects on the liver. Some drugs that can adversely affect the liver include acetaminophen (Tylenol and others), amiodarone (Cordarone), carbamazepine (Tegretol), isoniazid (INH), methotrexate (Rheumatrex), methyldopa (Aldomet), fluconazole (Diflucan), itraconazole (Sporanox), erythromycin (Erythrocin, Ilosone, others), phenytoin (Dilantin), lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), and many others.
