Phytoestrogens
Some botanical products, such as soy and red clover, contain estrogen-like compounds called phytoestrogens. Plants rich in phytoestrogens may help relieve some symptoms of menopause.
However, it is uncertain whether this relief comes from phytoestrogens or from other compounds in the plant. Much remains to be learned about these plant products, including exactly how they work in the human body. Doctors caution that certain women need to be particularly careful about using phytoestrogens, especially:
- Women who have had or are at increased risk for diseases or conditions that are affected by hormones, such as breast, uterine, or ovarian cancer; endometriosis; or uterine fibroids.
- Women who are taking drugs that increase estrogen levels in the body, such as birth control pills; MHT; or a type of cancer drug called selective estrogen receptor modulators (SERMs), such as tamoxifen.
