"Dioscorea villosa" is a species of a twining tuberous vine that is native to and found growing wild in North America. Its fame is based on its steroid-like saponins which can be chemically converted to progesterone [http://www.umm.edu/altmed/ConsHerbs/Wildyamch.html contraceptives] ; and cortisone.

Wild Yam is believed to be helpful to the liver and endocrine system. It regulates the female system, particularly during menstrual distress and menopause,as well as used in treating infertility. Used with chaste berry and dandelion it is an effective treatment for morning sickness.

Usually found wild in the eastern half of North America, it is a perennial plant that is a low creeper, and occupies average to poor soils and full sun.
