Black cohosh: This herb extract is used by some women to treat hot flashes and other menopausal symptoms. There's not enough evidence to support its use. Experts also are unsure of what risks taking black cohosh poses. Some studies have suggested that black cohosh was harmful to the liver, but other studies found no evidence that this is true.
Phytoestrogens: These estrogens occur naturally in certain foods. Two main type of phytoestrogens are isoflavones and lignans. Isoflavones are found in soybeans and other legumes and red clover. Lignans occur in flaxseed, whole grains, and some fruits and vegetables. There are also plant-derived compounds that have estrogen-like properties.
Bioidentical hormones: The term "bioidentical" implies that the hormones in the product are chemically identical to those your body produces. However, compounded bioidentical hormones aren't regulated by the US Food and Drug Administration (FDA), so quality and risks could vary.
Dehydroepiandrosterone (DHEA): This natural steroid produced by your adrenal gland is available as a dietary supplement and has been used by some to reduce pain during intercourse due to vaginal atrophy. But evidence on its effectiveness is mixed, and there are some concerns about possible harmful effects.
