Parts Used & Where Grown

Wild yam plants are found across the midwestern and eastern United States, Latin America (especially Mexico), and Asia. Several different species exist. All of which possess similar constituents and properties. The root is used medicinally.

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

Wild yam has been used by herbalists as an expectorant for people with coughs. It was also used for gastrointestinal upset, nerve pain, and morning sickness.1 Eventually, it was discovered that the saponins from wild yam could be converted industrially into cortisone, estrogens, and progesterone-like compounds. Wild yam and other plants with similar constituents continue to be a source for these drugs.
