One of the most celebrated North American medicinal plants, goldenseal's rhizome yields bright yellow berberine alkaloids with potent antimicrobial and anti-inflammatory action. Historically used by indigenous peoples for infections, digestive complaints, and eye conditions, it stimulates bile flow, tones mucous membranes, and fights bacterial and fungal overgrowth. Goldenseal is wildcrafted and at-risk — seek organically grown sources.
