Wild yam: Benefits, evidence, safety, and side effects

There are various other names for wild yam, such as colic root, devil’s bones, rheumatism root, or China root. While there are over 600 species of wild yam, only 12 are edible.

In this article, we investigate the potential medicinal uses of wild yam and the evidence supporting them. We also look at how to take it and its safety and side effects.

Benefits and uses

The bulb and roots of wild yams contain a chemical called diosgenin, which can influence the production of several useful hormones in humans, such as estrogen or dehydroepiandrosterone (DHEA). Consuming wild yam may be a natural way of promoting these hormones in the body, which could have certain medical benefits.

However, at present, there is little evidence to support any medical applications of wild yam. The United States Food and Drug Administration (FDA) have yet to evaluate wild yam for its safety or effectiveness.

Some of the potential medical uses of wild yam include:

Menopause symptoms

Some traditional medicine practitioners suggest using wild yam as an alternative to estrogen replacement therapy for treating symptoms of menopause. The theory is that wild yam may increase or stabilize estrogen levels in the body to help relieve a person’s symptoms.

However, there is very little evidence to support these claims. One of the only studies available on the topic found that the 23 women who applied a wild yam cream over a 3-month period experienced no changes in their menopausal symptoms.

The FDA have not yet evaluated wild yam for its medicinal use, so there is little detailed information on its safety or side effects.

Wild yam is a natural substance, but this does not mean it is free from side effects. In small doses, wild yam is considered safe for most people. However, large amounts of wild yam can lead to side effects, including:

  • nausea
  • vomiting
  • headaches
  • digestive issues

Some people may also have an allergic reaction to wild yam. For example, wild yam may cause skin irritation when applied as cream.

People who have hormone-sensitive conditions, such as breast cancer or uterine fibroids, should not use wild yam. It is possible for wild yam to influence estrogen production and worsen the condition.

There is also insufficient evidence about whether wild yam is safe during pregnancy, breast-feeding, or for young children. For this reason, doctors recommend people avoid using wild yam during these times.

Wild yam has been shown to interact with certain medications. For example, it can interact with estradiol, which is a substance used in certain birth control pills or hormone replacement therapies.

There may be other medications that wild yam can interact with, but further investigation is needed. It is essential to consult a doctor before taking wild yam to ensure it is safe for use.

Outlook

Although traditional medicine practitioners use wild yam to treat a variety of health conditions, further research is needed to determine its safety and effectiveness.

Wild yam may interact with other medications, and consuming large amounts can lead to side effects. It is, therefore, necessary to speak to a doctor before taking wild yam.
