In the Brazilian tradition, the self-applicator pipe is called “Kuripe”, and the blow pipe to pass another person is called “Tepi”.
Traditionally, rapé is applied by using a pipe made from bamboo or bone, which is blown through each nostril on both sides. They can be self-administered using a V-shaped self-applicator pipe, which connects the mouth to the nostrils – Kuripe.
Alternatively, the can be administered by another person using a blow pipe, which connects the blower’s mouth to the other person’s nostrils – Tepi.
You always put the shorter end of either pipe in your mouth to blow, and the longer end goes inside the nostril.
