Humr

'red') are one of two branches of the Messiria, a subgroup of the Baggara ethnic group, native to the south-west province of Kordofan, Sudan.

[4] The Humur are most commonly known outside the Sudan as the preparers of a drink made from the liver and bone marrow of a giraffe, which they call umm nyolokh, and which they claim is intoxicating, causing dreams and hallucinations.

[5] Ian Cunnison, who accompanied the Humr on some of their giraffe-hunting expeditions in the late 1950s, noted that: It is said that a person, once he has drunk umm nyolokh, will return to giraffe again and again.

[4]Cunnison's account of a psychoactive mammal found its way into a mainstream literature through a conversation between Dr. Wendy James of the Institute of Social and Cultural Anthropology at the University of Oxford and specialist on the use of hallucinogens and intoxicants in society Richard Rudgley, who considered its implications in his popular work The Encyclopedia of Psychoactive Substances.

Rudgley hypothesises that the presence of the hallucinogenic compound DMT might account for the putative intoxicating properties of umm nyolokh.
