Superpure Wild Yam Root Extract
Also known as: Dioscorea villosa, Wild Yam, Colic Root
Overview
Wild yam root is a plant-based supplement derived from *Dioscorea villosa*. It is often used for its purported hormonal benefits, although scientific evidence supporting these claims is limited. Wild yam contains diosgenin, a plant steroid that can be chemically converted into hormones like estrogen and progesterone in a laboratory setting, but not in the human body. The research maturity level for wild yam is moderate, with most studies focusing on its potential effects on menopause symptoms and hormonal balance. However, the quality of available evidence is generally low due to the lack of robust clinical trials. It is available in various forms, including capsules, creams, and tinctures. Wild yam is sourced from the roots of the *Dioscorea villosa* plant, which is native to North America. While some proponents suggest benefits for hormonal imbalances, these claims are not supported by robust scientific evidence.
Benefits
There is limited evidence supporting the effectiveness of wild yam for alleviating menopause symptoms such as hot flashes and night sweats. Most studies indicate that it does not significantly affect hormone levels or menopausal symptoms. Some proponents suggest benefits for hormonal imbalances, but these claims are not supported by robust scientific evidence. The available data do not demonstrate significant clinical effects for any particular population. Given the lack of efficacy, there is no established time course for benefits. Studies have shown that topical wild yam extract did not significantly affect menopausal symptoms or hormone levels in healthy menopausal women.
How it works
Wild yam contains diosgenin, which can be converted into steroids in a laboratory but not in the body. It does not directly interact with hormonal pathways in humans. There is no clear evidence of how wild yam interacts with human body systems to produce significant biological effects. The bioavailability of diosgenin from wild yam is not well-studied, but it is known that the body cannot convert it into active hormones. Therefore, the purported hormonal benefits are not supported by a clear mechanism of action within the human body.
Side effects
Wild yam is generally considered safe when used orally for short periods (up to 12 weeks) and when applied topically. However, there is limited data on long-term use. Common side effects may include vomiting, upset stomach, and headache with oral intake of large amounts. Potential interactions with hormone-sensitive medications may occur due to its theoretical estrogen-like effects. It is contraindicated in conditions sensitive to estrogen, such as breast cancer, uterine cancer, and endometriosis. Use should be avoided during pregnancy and breastfeeding due to insufficient safety data. It's important to consult with a healthcare provider before using wild yam, especially if you have any underlying health conditions or are taking medications.
Dosage
Due to the lack of established efficacy, there is no established minimum effective dose or optimal dosage range for wild yam. Oral use is generally considered safe for up to 12 weeks, but specific dosages are not well-defined. There are no established timing considerations or form-specific recommendations, although topical creams are commonly used for menopause symptoms despite a lack of robust evidence supporting their effectiveness. Absorption factors are not well-studied, and there are no required cofactors. Given the limited research, it is important to exercise caution and consult with a healthcare professional before using wild yam.
