Scientific Name

Dioscorea villosa


Progesterone, a female hormone, is now known to be produced in wild yam.  Research has not proven progesterone-like action in the body, however.  It stimulates bile to be released in the gall bladder and treats pain and spasms.  It has been used to treat urinary tract problems as well.
