Decreased estrogen levels in the body lead to uncomfortable menopausal symptoms such as hot flashes, vaginal dryness, thinning bones and decreased libido. Conversely, increases in estrogen can cause or exacerbate breast, ovarian and cervical cancer as well as ovarian cysts. Some women who use synthetic hormone replacement medication to alleviate symptoms of menopause might want to use herbs that mimic estrogen or stimulate estrogen production, while other women might want to avoid herbs that increase estrogen in the body. As with any herbal supplement, it is important to remember that "herbal" is not synonymous with "safe," and you should always talk to your doctor before discontinuing prescribed medication or using herbal medicines.
Red Clover
Red clover is a nutritious legume that is grown to feed grazing animals. It is a rich source of vitamin C, calcium and potassium. Additionally, it is very rich in isoflavones. Isoflavones are a chemical that has a very similar structure to estrogen and can mimic it in the body. Many women have reported that red clover decreases menopausal symptoms like hot flashes, and the isoflavones and calcium in the herb can help slow losses in bone density. The estrogen-like chemical can also help slow some cancers, but speed up others, just as synthetic and natural estrogen do. The University of Maryland Medical Center points out that studies on the benefits and dangers of red clover are still inconclusive, but they recommend that women with a family history of breast cancer should avoid this herb.
Black Cohosh
Native American women have used black cohosh for centuries to alleviate menstrual cramps, as well as menopausal symptoms like hot flashes, night sweats and mood swings. This herb is also widely used in Europe to treat the discomforts associated with menopause, and is approved in Germany for this use. It is a phytoestrogen, which means it's a plant that contains chemicals that are similar to the raw ingredients the body uses to make estrogen. Black cohosh can also alleviate the hot flashes associated with the cancer medication tamoxifen. Although there have been no conclusive studies that show the herb can speed the development of cancer, the National Institute of Health recommends women with breast cancer to avoid using the herb. They also caution that black cohosh should not be used for more than six months until its effects are better known.
Dong Quai
Of all the herbs traditionally used to alleviate symptoms associated with low estrogen, dong quai is among the most well known, but least clinically researched supplement. This root herb has been used in Chinese medicine for centuries to reduce menstrual cramps and symptoms of menopause. Dong quai may have estrogen-like effects, and it can both stimulate and relax uterine muscles. For this reason, pregnant women should not use dong quai because of the increased risk of miscarriage. The University of Maryland Medical Center also warns that women with fibroid cysts, and breast, ovarian or cervical cancer should also avoid the herb because researchers are not certain if it's estrogen-like effects are harmful.
