Black Cohosh, an herbal “supplement” (i.e. unregulated drug) remains popular for the treatment of hot flashes and other autonomic symptoms resulting from menopause. This product is yet another good example of the double standard that the supplement industry and ideological promoters are allowed to employ.
The NCCAM website gives this summary:
Black cohosh, a member of the buttercup family, is a plant native to North America. It has a history of use for rheumatism (arthritis and muscle pain) but has been used more recently to treat hot flashes, night sweats, vaginal dryness, and other symptoms that can occur during menopause.
While the information is available if you look through the links below, their summary makes no mention of the fact that their own studies show black cohosh is ineffective. In their “at a glance” summary they characterize the scientific evidence as “mixed.”
For years postmenopausal women were told that estrogen was safe. Now they’re being told that estrogen is dangerous. Women are confused. The media haven’t helped; they’ve only increased the confusion and created some myths. Alternative medicine offers the option of herbal remedies they say are safer than estrogen. Suzanne Somers says all of us (even men!) should be taking bioidentical hormones and adjusting our own doses according to how we feel. What’s a woman to do? What does the science really say?
Before the Women’s Health Initiative (WHI) of 2002, there were two main reasons for prescribing hormone replacement therapy (HRT): it relieved perimenopausal symptoms like hot flashes, and it helped prevent osteoporosis and fractures. There was good reason to believe that estrogen might also reduce the risk of heart attacks, but very few doctors (if any) ever prescribed it for the sole purpose of reducing heart risks. And doctors were always aware that estrogen and progestins were powerful drugs and were not risk-free.
There was a time in the mid-20th century when estrogen was thought to be a fountain of youth and women were encouraged to start taking it at menopause and continue for the rest of their lives. That attitude quickly changed as we realized these hormones were associated with blood clots, strokes, and increased rates of some cancers. We also learned that unopposed estrogen caused uterine cancer, and women who still had their uterus had to take progestins along with their estrogen. (more…)
