Alfalfa Overview
Alfalfa, also known as Lucerne, is a perennial flowering plant in the pea family Fabaceae. It is native to southwestern Asia and the Mediterranean region, but it is now grown in many parts of the world, mainly as a forage crop for livestock. Alfalfa is a rich source of vitamins and minerals, such as vitamins A, C, E, and K, and manganese. It also contains coumestrol, a phytoestrogen. It has been used as a natural remedy for a variety of conditions, such as arthritis and high cholesterol. It may also help treat gastrointestinal disorders, rheumatoid arthritis (RA), asthma, menstrual irregularities, as well as bladder, kidney, and prostate issues.
