Gravel Root goes by numerous aliases; in addition to its scientific name, Eupatorium purpureum , it is commonly known as gravelweed, kidneywort, purple boneset and jopai weed - reportedly after an Algonquin Indian from New England whose name was Jopai ("Joe Pye"), a shaman who became known for curing complaints with the use of Native American herbs like cut Gravel Root.
