Goldenseal grows as a perennial in Southeastern Canada and the Eastern US. It was a revered Native American and Eclectic remedy, used to soothe inflammatory conditions affecting the mucous membranes of the respiratory, digestive, and genitourinary systems.
Much of its effects appear to be related to the presence of isoquinoline alkaloids, mainly hydrastine, berberine, berberastine, canadine, candaline, and hydrastinine. Its bitter components stimulate secretions of the liver, gall bladder, and spleen, and revive the appetite. Berberine in particular has been extensively studied for its anti-microbial, immune-boosting, and astringent actions.
Goldenseal should not be used during pregnancy.
