Health Notes

Wild Yam

Wild Yam
This nutrient has been used in connection with the following health goals
  • 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.

This supplement has been used in connection with the following health conditions:

Menopause
Dose: Refer to label instructions
Wild yam is an herb with weak estrogen-like actions similar to soy. In one trial, a formula containing licorice, burdock, dong quai, wild yam, and motherwort reduced menopause symptoms.(more)
Menopause

High Cholesterol
Dose: Refer to label instructions
Wild yam has been reported to raise HDL ("good") cholesterol in preliminary research.(more)
Menopause
Dose: Refer to label instructions

A variety of herbs with weak estrogen-like actions similar to the effects of soy have traditionally been used for women with menopausal symptoms.1 These herbs include licorice, alfalfa, and red clover. In a double-blind trial, a formula containing tinctures of licorice, burdock, dong quai, wild yam, and motherwort (30 drops three times daily) was found to reduce symptoms of menopause.2 No effects on hormone levels were detected in this study. In a separate double-blind trial, supplementation with dong quai (4.5 grams three times daily in capsules) had no effect on menopausal symptoms or hormone levels.3 A double-blind trial using a standardized extract of subterranean clover (Trifolium subterraneum), a relative of red clover, containing 40 mg isoflavones per tablet did not impact symptoms of menopause, such as hot flashes, though it did improve function of the arteries.4 An extract of red clover, providing 82 mg of isoflavones per day, also was ineffective in a 12-week double-blind study.5 In another double-blind study, however, administration of 80 mg of isoflavones per day from red clover reduced the frequency of hot flashes in postmenopausal women. The benefit was noticeable after 4 weeks of treatment and became more pronounced after a total of 12 weeks.6
