What Is African Shea Butter Used For?

You were looking around at the store the other day and you came across some African Shea Butter in among all the different lotions. What exactly is this kind of lotion or cream used for? Is it just like any other lotion, or is it good for treating any certain kinds of conditions? Since it is more expensive than the lotion you usually buy you are trying to figure out what would make it worth the extra money. If it is better than what you are using it would be worth a try since your skin has been really dry lately.
