Rapé is a snuff which is blow into each nostril through a pipe known as a ‘Tepi’, which is either made from a hollow bone or bamboo. Each tribe has their own formula of plants, trees, seeds, most commonly combined with a pure form from the Amazon and an ash called tsunu, or others like Murici, Yarumo, or Inga. The rapé is prepared in a ritualistic way by specific members of the tribe.
 
Spirit of Nature
In some tribes, it is the women who gather the ingredients and make the Rapé, and others are made by the healer of the tribe.
