Red clover is a perennial herb traditionally used to treat skin conditions such as eczema and psoriasis, whooping cough, and respiratory problems. The isoflavones present in red clover have estrogen-like effects and have been the subject of intense research over the last decade.
Data on red clover's potential for reducing the symptoms of menopause and for decreasing the risk of breast cancer are inconclusive. Overuse of isoflavone supplements can increase the risk of hormone-sensitive cancer.
Recent findings from a preclinical study suggest that red clover may increase resistance of prostate cancer cells to high-dose radiation while inhibiting the growth of normal prostate cells. Until definitive data are available, patients should avoid use of red clover during radiotherapy for prostate cancer.
