- Dosing considerations for Wild Yam.
There are over 600 species of wild yam. Some species are grown specifically as a source of diosgenin for laboratories to use in making steroids. These species are generally not eaten due to a bitter flavor. Only about 12 of the 600 species are considered edible.
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.
Similarly, you will also see wild yam and diosgenin promoted as a "natural DHEA." This is because in the laboratory DHEA is made from diosgenin, but this chemical reaction is not believed to occur in the human body. So taking wild yam extract will not increase DHEA levels in people. Individuals who are interested in taking DHEA should avoid wild yam products labeled as "natural DHEA."
Wild yam is also used for treating a disorder of the intestines called diverticulosis, gallbladder pain, rheumatoid arthritis, and for increasing energy.
Some women apply wild yam creams to the skin to reduce menopausal symptoms such as hot flashes.
Possibly Ineffective for...
- Menopausal symptoms. Applying wild yam cream to the skin for 3 months does not seem to relieve menopausal symptoms such as hot flashes and night sweats. It also does not seem to affect levels of hormones such as follicle stimulating hormone (FSH), estradiol, or progesterone, which play a role in menopause.
Insufficient Evidence to Rate Effectiveness for...
- Use as a natural alternative to estrogens.
- Postmenopausal vaginal dryness.
- PMS (Premenstrual syndrome).
- Weak bones (osteoporosis).
- Increasing energy and sexual desire in men and women.
- Gallbladder problems.
- Painful menstrual periods.
- Rheumatoid arthritis.
- Menstrual disorders.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
