Facts

Goldenseal is widely distributed in eastern North America, but it is very rare in New England, where it is found in the western portions of Connecticut, Massachusetts an Vermont, in all of which it is listed as endangered. Threats include illegal collecting for medicinal purposes, as this species has a long history of use as a medicinal herb. Fortunately it is widely available to buy and easy to cultivate. Native Americans used goldenseal to treat cancer, liver conditions, fevers, pneumonia, tuberculosis and other ailments.
