Gall medicine is made of the gall bladders of eagles, mountain lions, bear, and skunk. Occasionally the gall bladders of sheep, wolf, badger, and deer are also used. Navajos carry this medicine with them, sometimes in small bags or pouches, for protection against witches, corpse poison, and strangers. It is most often carried on their person when they are in a crowd, for example during ceremonies, or when traveling outside their home territory.
