Yagé

Copy (of a) Report on Yagé.

Holograph draft (on rectos only).

Holmes refers to a conversation initiated by Sir H. Rider Haggard (1856-1925) on a South American drug 'causing clairvoyant and telepathic effects', to the identification of the drug, and to the writer's attempts at trial with a tincture prepared by W.H. Martindale (1875?-1933) on 'some of our leading scientific Spiritualists ... including Sir A. Conan Doyle, Professor (Sir) Oliver Lodge, & Sir (W.) F. Barrett.'

The author, aware of difficulties of identification and nomenclature, describes indigenous methods of preparation, and refers to a full account of the drug by A. Rouhier in Bulletin des Sciences Pharmacologiques, 1926, 33, 252-261, and to South American work on it.

Produced in London.

See Martindale (1977), p. 883 for a succinct account of the alkaloidal relationship of yagé (Colombia), with caapi (Brazil and Colombia), and with the better known ayahuasca (Ecuador, Peru and Bolivia).
