Safety and cautions
Contraindications: Memorial Sloan Kettering lists these as contraindications: known allergy to kudzu, hormone-sensitive cancers (including ER-positive breast cancer, because kudzu has oestrogen-like activity), and use of tamoxifen. It may add to the effect of diabetes medicines, may raise methotrexate levels (rat data), and may alter how some medicines are processed (CYP2D6 and CYP1A2). Rare cases of kidney inflammation and liver injury have been reported. Pregnancy was not addressed in the source: ask a doctor first. Always check with your prescriber or pharmacist, especially if you take blood thinners or other regular medicines.
Herbs can interact with prescription medicines and other supplements. Check with your prescriber or pharmacist first, and do not use herbs in pregnancy or while breastfeeding unless a doctor agrees.
