Kikuyu purification ceremony. A Kikuyu witch doctor performs a traditional purification ceremony to absolve a man of his sins. In this ritual, the perpetrator is fed a concoction of herbs and minerals, mixed with the undigested stomach contents from a sacrificed goat. The mixture is then spat or vomited out to cleanse the offender of their sins. South Nyeri, Kenya, 1936. Nyeri, Central (Kenya), Kenya, Eastern Africa, Africa.
