Red Clover Overview
Red clover (Trifolium pratense) is a perennial plant that is native to Europe and Asia, but is also found in many parts of the world, including North America.
Red clover has a long history of use in traditional medicine and is believed to have a number of potential health benefits. It is a rich source of isoflavones, which are thought to have estrogen-like effects and is therefore often marketed for women's health. It has been used to treat hot flashes and other menopause symptoms as well as cardiovascular disease, high cholesterol, and osteoporosis.
