Wild yam does not equal progesterone. Wild yam and soy are the raw materials from which laboratory-produced progesterone is formulated commercially. Look at any OTC progesterone cream. If it says "natural" it was made from soy or mexican wild yam.

It took years to figure out the biochemistry and enzymatic pathways to do that in the laboratory and make it commercially viable. According to experts that understand the biochemistry better than I, it is VERY unlikely that the same conversion happens in the body. Those multistep enzymatic pathways do NOT exist in our bodies. This is a good article on the topic, though it's not original research: http://heartspring.net/progesterone_cream.html

While progesterone may be beneficial to take with PM, it would probably be more cost effective to stick with a high quality OTC progesterone cream.

Hope this helps.
