Kikuyu purification ceremony. A Kikuyu man takes part in a purification ceremony, drinking a witch doctor's concoction from the nose of a sacrificed goat. Traditionally, the concoction is made from herbs and minerals, mixed with the goat's undigested stomach contents. It is administered by an elder or witch doctor, and either spat or vomited out to cleanse the perpetrator of their sins. South Nyeri, Kenya, 1936.
