The rhizome has been used to treat indigestion, gout, and rheumatism; and it has also been used as an antiemetic. Because of its bitter flavor, probably the most useful application of this plant is as a tonic and astringent. In Appalachia, a root tea is drunk as a tonic, and a piece of the root is sometimes worn or carried to increase oneís physical powers.
