There has been much safety research done on Black Cohosh Root. It is important to note that the kind of black cohosh used in Estroven® products is Cimicifuga racemosa, the North American herb, rather than the Asian variety, which may not have the same degree of purity or effectiveness.
Black Cohosh is a rich source of natural compounds that has been shown to help reduce hot flashes.* It has been used for centuries throughout the world to provide support for many areas of female health. Renowned for its long tradition as a beneficial herbal remedy for the relief of moderate to severe menopausal symptoms related to the autonomic nervous system (e.g., hot flushes, insomnia, nocturnal sweating, dizziness, headaches), black cohosh is used to alleviate psychological menopausal symptoms (e.g., irritability, anxiety).*1
A high purity, standardized Cimicifuga racemosa extract from the root and rhizomes is used in Estroven® products, providing the therapeutic doses of triterpene glycosides (triterpene saponins).* These naturally-sourced standardized extracts have been studied extensively as demonstrated by the abundance of scientific literature, with over 1,500 patients experiencing a good to very good therapeutic response.*2
Some of the leading medical journals have supported the use of American grown black cohosh to reduce menopause symptoms, including the Journal of Women’s Health, which states, "The evidence to date suggests that black cohosh is safe and effective for reducing menopausal symptoms, primarily hot flashes and possibly mood [changes]."* The North American Menopause Society (NAMS) recommends dietary Soy Isoflavones, Black Cohosh, or vitamin E for women who need mild relief from hot flashes and night sweats.*
Germany's Kommission E, a governmental regulatory body similar to the U.S. Food & Drug Administration (FDA), has approved the use of Black Cohosh for menopausal symptoms.* This scientific panel, which has done its own investigation and review of the safety and efficacy of North American Cimicifuga racemosa, has concluded that it is useful and warranted in helping these menopause symptoms.*
