Professor Russel Marker showed progesterone and oestrogen could inexpensively be synthesized from diosgenin, a plant compound structurally similar to certain hormones found in the body and the active constituent in wild yam root. It is believed this synthesis is also accomplished in the body when diosgenin is applied topically for absorption into the blood. The use of Wild Yam Extra Strength Gel can offer the user an alternative for hormonal balance without the side effects or toxicity associated to some prescription products. Only At Last Naturals Wild Yam products are made from fresh whole Mexican wild yam root. A complex six week process insures that the freshness and potency of wild yam extracts are at their highest levels.
