My personal opinion:  Looks like over-priced snake oil.
Wild yam isn't progesterone, and body can't convert it  to progesterone. I wouldn't buy anything if the ingredient list doesn't include something like "bioidentical progesterone" or has "USP". 

The raw material may be wild yam, but a chemical processing with many steps is required to make it to an active hormone.

All progesterone (produced outside of the body-aka- exogenously) starts from plant (e.g. soy or wild yam). To get it to bioidentical progesterone (or USP) those plants have to be further synthesized to achieve that tag of "USP and Bioidentical".
