According to James Mooney, the Cherokee Indians made use of the plant in their sweat baths for various diseases and it was considered one of their most valuable medicinal plants. [9]
James Mooney was an American ethnographer who lived for several years among the Cherokee. Known as "The Indian Man", he conducted major studies of Southeastern Indians, as well as of tribes on the Great Plains. He did ethnographic studies of the Ghost Dance, a spiritual movement among various Native American culture groups, after Sitting Bull's death in 1890. His works on the Cherokee include The Sacred Formulas of the Cherokees (1891), and Myths of the Cherokee (1900). All were published by the US Bureau of American Ethnology, within the Smithsonian Institution.
