Alfalfa (Medicago sativa) is an herb that some people consume as a source of calcium, potassium, phosphorous, iron, and vitamins A, C, E, and K.

Alfalfa is most commonly grown as food for livestock animals. In humans, it’s often eaten as a garnish, and seems to prevent cholesterol absorption in the stomach.

People use alfalfa for high cholesterol, diabetes, indigestion, and many other conditions.
