[Why] Burdock is an herb with weak estrogen-like actions similar to soy. In one trial, a formula containing tinctures of licorice, burdock, dong quai, wild yam, and motherwort reduced menopause symptoms. A variety of herbs with weak estrogen-like actions similar to the effects of soy have traditionally been used for women with menopausal symptoms.7 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.8 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.9 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.10 An extract of red clover, providing 82 mg of isoflavones per day, also was ineffective in a 12-week double-blind study.11 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.12 [Used for]
