Red clover (Trifolium pratense) is an herb that belongs to the legume family, which also includes peas and beans. Red clover's brightly colored flowers contain many nutrients including calcium, chromium, magnesium, niacin, phosphorus, potassium, thiamine, and vitamin C. They're also a rich source of isoflavones. These are compounds that act as phytoestrogens—plant chemicals similar to the female hormone estrogen. Isoflavone extracts are touted as dietary supplements for high cholesterol and osteoporosis in addition to menopausal symptoms. In herbal medicine, red clover is typically used to treat respiratory issues (such as asthma, whooping cough, and bronchitis), skin disorders (such as eczema and psoriasis), inflammatory conditions like arthritis, and women's health problems (such as menopausal and menstrual symptoms).
