Ethnobotany: The Chippewa used the roots to prepare a remedy for skin inflammation (Densmore, p. 348, 1928). Densmore uses the old synonym name Eupatorium maculatum for this plant. The Algonquin used the plant to treat venereal disease and to aid women after childbirth. The Cherokee and the Iroquois used this plant to treat several ailments (Moerman, p. 229, 1998).
