Wild Yam - Contains a chemical, diosgenin, which can be made in the laboratory into various steroids, such as estrogen and dehydroepiandrosterone. The root and the bulb of the plant are used as a source of diosgenin, which is prepared as an “extract,” a liquid that contains concentrated diosgenin.Diosgenin or wild yam is often promoted as a “natural alterative” to estrogen therapy, so you will see it used for estrogen replacement therapy, vaginal dryness in older women, PMS (premenstrual syndrome), menstrual cramps, weak bones (osteoporosis), increasing energy and sexual drive in men and women, and breast enlargement. Wild yam does seem to have some estrogen-like activity, but it is not actually converted into estrogen in the body. It takes a laboratory to do that.
My personal observatin concerning this plant - Wild Yam is usaly plentyful when ou find it.It grows very well in rocy areas and briar thickets.In the same areas that you would exspect to see a rattlesnake that type of terrain is where the Yams thrive.I have done very good digging Yam.We usaly do not harvest Yam untill the later mounths of winter as the vine stands after it has died and the seed has been well sown.A good digger can dig (in a good area)from 65 to 100 pounds in a day and will earn between $60.00 to $100.00 dollors per days work after drying.
One of my personal favorites because I can dig it in the winter mounths.
I have sevral of those that I will share with you all.
