Wikipedia tells me this about the Joe-Pye Weed:
Joe Pye (Jopi in the Native tongue), an Indian healer from New England used E. purpureum to treat a variety of ailments, which led to the name Joe-Pye weed for these plants. Folklore says that Joe Pye used this plant to cure fevers. Folklore also states that American colonists used this plant to treat typhus outbreaks.
