Progesterone is a hormone produced primarily by the ovary but also in smaller amounts by the adrenal glands. "Natural" progesterone refers to the type that matches exactly the substance produced in a woman's body, as opposed to "progestins" which are synthesized molecules produced by pharmaceutical companies as drugs. Natural progesterone is derived from precursors such as wild yam that can be converted through an industrial process into natural progesterone-the exact same molecule made in the human body. However, contrary to popular claims, wild yam is not the same as progesterone and cannot be converted into progesterone by the body.

Beneficial effects

Premenstrual syndrome - As natural progesterone is not a drug, there a few studies on this compound. One exception is work done by Dr. Katharina Dalton in the 1950's. She utilized various routes of administration of progesterone and did note an 83% decrease in overall symptoms in women with PMS. There does exist considerable anecdotal data since that time that is consistent with this beneficial effects of natural progesterone for PMS symptoms. Dr. John Lee and Dr. Betty Kamen have written extensively on the use of natural progesterone in their books and have reported significant success with the use of this natural hormone.

Menopause - Progesterone has been used for the relief of many menopausal symptoms and to balance the effects of estrogen on the uterus. While again, little scientific study has been completed due to the fact that pharmaceutical companies have no incentive to do so, there is extensive medical clinical experience with the use of natural progesterone for relief of hot flashes, night sweats, vaginal dryness and mood swings. Preliminary evidence suggests that progesterone also plays a role in bone metabolism that could help reduce the risk of osteoporosis but more study is needed on this issue.


Wild yam is composed of a number of chemical constituents which are believed responsible for its effects. The steroidal saponins (such as diosgenin) account for some of wild yam's activity. An extract of wild yam was found to have antioxidant properties. It has also been shown to lower blood lipids and to raise HDL (the "good" cholesterol). Contrary to popular claims, wild yam roots do not contain and are not converted into progesterone or DHEA in the body. However, wild yam saponins or other constituents may have properties similar to these compounds that account for its beneficial effects in hormonal support of women.

Side effects

Side effects have been reported in under 4 percent of women using natural progesterone. These include breast tenderness, drowsiness, depressive moods, headaches and irritability. In general, transdermal progesterone is well tolerated. Some people may experience nausea when taking large amounts of wild yam. This would be unlikely in the dosages found within this product.

At the time of writing, there were no well-known drug interactions with wild yam or progesterone.
