Estrogenic effect of yam ingestion in healthy postmenopausal women

The researchers objective in this 24 person study was to understand why yam has been used to treat menopausal symptoms folklorically.

What they found was that replacing two-thirds of staple food (rice) with yam for 30 days improved the status of the women's sex hormones, lipids, and antioxidant levels. The same results were not seen in a group that was given sweet potato.

Bonnie - this is one of the first studies I have seen structured this way and I am impressed, albeit not suprised with the results. I would like them to some more larger studies so wild yam will be taken more seriously.
