Raw milk is useful in preventing disease, by strengthening the immune system with colostrum and CLA, but its uses as a cure specifically are less obvious.
That is, if you don't mind taking the risk of contracting listeriosis, tuberculosis, brucellosis, E. coli O157:H7, rabies, and just about any other disease a cow can catch from wild animals. I'll stick with the pasteurized stuff, myself.
