Ancient Chinese doctors used alfalfa to increase appetite and to help poor digestion. Modern day herbalists promote it for detoxification believing that it can help relieve certain types of ulcers, reduce inflammation due to arthritis, treat high fevers, cleanse the liver and bloodstream, and alleviate allergic reactions related to plants and grasses. There are few if any valid scientific studies to support these claims, however, it's proven as an excellent source of vitamins, minerals, fiber, proteins, and fats and is especially rich in the amino acid tryptophan, iron, and vitamins A, D and K.
