Goldenseal Root Powder
Also known as: Hydrastis canadensis, Goldenseal, Hydrastis, Yellow root
Goldenseal is a traditional North American herb traditionally used for immune support and digestive health, containing the alkaloid berberine as its primary active compound. Clinical evidence for efficacy is limited and inconsistent, with most studies examining berberine rather than goldenseal extract directly.
