herbs - Goldenseal (Hydrastis canadensis)

What is it?

Goldenseal is a perennial herb native to eastern North America, but is now cultivated due to over harvesting in the wild. Native Indians used it for respiratory problems and as a clothing dye. The knotty yellow rhizome and roots are used in herbal medicine. 

Action

Goldenseal contains high levels of berberis alkaloids, namely berberine and hydrastine. These compounds have potent anti-microbial and antibiotic actions and can destroy bacteria, protozoa and fungi. It also improves blood supply to the spleen, which influences immune function. In addition, it is a uterine tonic, liver stimulant and potent detoxifier.
