Dioscorea villosa is a species of a twining tuberous vine that is native to eastern North America. It is common and widespread in a range stretching from Texas and Florida north to Minnesota, Ontario and Massachusetts.[1][2][3][4]

Creams and dietary supplements made from Dioscorea villosa are claimed to contain human hormones and promoted as a medicine for a variety of purposes, including cancer prevention and the treatment of Crohn's disease and whooping cough. However, according to the American Cancer Society, the claims are false and there is no evidence to support these substances being either safe or effective.[5]
