Researchers may have found a remedy in the Chinese herb Prunella vulgaris (PV) for women with endometriosis and certain types of cancer.
The Chinese herb Prunella vulgaris (PV) may prove an effective treatment for women with endometriosis and certain types of cancer because of its anti-estrogen properties, according to research published in the November 5 issue of the journal, Biology of Reproduction.
Although the female hormone, estrogen is crucial to reproduction, it can have some negative side effects, fueling the abnormal cell growth that occurs in diseases such as endometriosis and cancer. To treat these diseases, doctors have turned to tamoxifen and other anti-estrogen medications, but these drugs can have significant side effects.
In their search for an alternative to anti-estrogen medications, researchers in Greenville, South Carolina focused their attention on several possible herbal remedies. “We had 20 herbs in the lab that included Prunella vulgaris,” says Bruce Lessey, MD, PhD, vice chair of Research, and director of Reproductive Endocrinology and Infertility at Greenville Hospital System. PV is found in Europe and Asia and is often used to treat painful periods. “There had been one study previously suggesting that a related herb, Prunella stica, had anti-estrogen properties. So we screened the herbs, and this one really jumped out.”
