Wild yams have been in use for thousands of years, but it is only in modern times that we can recognize the full potential of this healthy vegetable and herbal supplement.

What Are Wild Yams?

Wild yams are the wild variety of commonly known sweet potatoes and go by the scientific name Dioscorea villosa. There are more than 600 varieties of wild yam, but only a dozen or so are considered edible. However, their tubers are valuable due to a chemical compound found inside called diosgenin. This compound is a precursor to certain steroidal hormones such as progesterone, that is important for boosting the female reproductive health. While extracts and tinctures from this vegetable have long been used in traditional medicine, there’s still some debate about the efficacy of raw wild yam on the body. Using wild yam cream on the skin is also believed to be an effective anti-inflammatory medicine.
