The milt is said to look like a piece of liver and is present in the foal's mouth at birth. Its purpose is somewhat mysterious, but it may help prevent fluid from entering the mouth and choking the foal during the birth process.  Another suggestion is that the milt is related to the formation of the horse's tongue.  Rual legend says the milt should be dried and placed on the stable roof as a magical protection to all within.  Native American medicine men and rural horse whisperers also considered dried milt to have healing power.
