Goldenseal

Hydrastis canadensis

Family: Ranunculaceae  |  Parts Used: Root

Goldenseal is a potent bitter herb native to North America, long used in Native American herbalism for conditions affecting mucous membranes. Its primary alkaloids, berberine and hydrastine, drive its antimicrobial and anti-inflammatory actions. It supports immune function during acute infections, assists liver and gallbladder function, and is applied externally for skin irritations and wound healing. Because of its strength, it is reserved for short-term use only.
