Rattlesnake Master produces unique white bristly flowers. In the past, Rattlesnake Master was used medicinally by Native Americans as a diaphoretic and as a remedy for rattlesnake bites. James Adair, an 18th century Irish historian who lived and studied Native Americans for much of his life, recorded stories of warriors applying a preparation of this plant to their arms as protection from the ill effects of venom. More commonly, it was used to brew a medicinal tea. The roots have also been used to treat liver troubles.
