Alfalfa is one of the oldest cultivated plants. It has been used for centuries for hay, but it has also been used for centuries as a human food. Its name comes from the Arabic, al-fac-facah, "father of all foods."

 

Alfalfa is one of the best natural sources of vitamin K. This nutrient helps blood to clot by moving calcium into proteins that form a microscopic net to capture red blood cells. Vitamin K likewise helps bones to knit by working with vitamin D and glutamic acid to activate osteocalcin. The combination of these three nutrients is essential to building good bone. Your body can not use calcium without it. Alfalfa not only helps keep calcium in bones, it helps keep calcium out of the linings of arteries.

 

Caution:

 For most people, alfalfa sprouts are inherently safe, but they do interact with certain medications. If you're taking anti-rejection drugs for kidney transplant, don't use any form of alfalfa.
