In one 30-day study, 24 postmenopausal women switched from their staple food of rice to eating yams in 2 out of 3 meals (390 grams total) per day. Their blood levels of estrone and estradiol increased by 26% and 27%, respectively. Blood levels of estrone and estradiol — two estrogen hormones — typically decrease during menopause. Improving estrogen levels may ease menopause symptoms. Yet, another six-month study found that topically applied wild yam cream had very little effect on menopause symptoms, such as flushing and night sweats, compared with a placebo Further research is needed to investigate the role that yams may have in relieving menopause symptoms.
