Overview

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, but there is no good scientific evidence to support these uses.

Special Precautions and Warnings

When taken by mouth: Alfalfa leaves are possibly safe when used short-term. But taking alfalfa in high doses or long-term is likely unsafe. Long-term use might cause reactions similar to the autoimmune disease called lupus in some people.
Pregnancy and breast-feeding: Using alfalfa in amounts larger than what is commonly found in food is possibly unsafe during pregnancy and breast-feeding. Alfalfa might act like estrogen in the body.

"Auto-immune diseases" such as multiple sclerosis (MS), lupus (systemic lupus erythematosus, SLE), rheumatoid arthritis (RA), or other conditions: Alfalfa might cause the immune system to become more active, and this could increase the symptoms of auto-immune diseases. If you have an auto-immune condition, avoid using alfalfa until more is known.

Hormone-sensitive condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Alfalfa might have some of the same effects as estrogen. If you have any condition that is sensitive to estrogen, don't use alfalfa.
