Alfalfa is considered to be a nutritional supplement and a body cleanser. Its leaves are shown to nourish the body by stimulating the appetite, acting as a laxative and diuretic, and providing such nutrients as fiber, protein, calcium and vitamin A (beta-carotene).

Alfalfa also has been shown to help relieve inflammation of the bladder, bloating or water retention, indigestion, constipation, and halitosis (bad breath).
