If you take wild yam your body won't be able to turn that into progesterone. Those natural / bioidentical Progesterone creams are made as follows:

"Laboratories take wild yam or soybean, extract a plant hormone called diosgenin, and convert that to progesterone. Diosgenin does not turn into progesterone in human body. The conversion has to be done in laboratories."

I quoted it from this website: http://home.hiwaay.net/~eueda/progesterone/whatis.htm
