Studies in Santal Medicine and Connected Folklore (1940)

Featured article

Studies in Santal Medicine and Connected Folklore is an ethnographic study of the medicine and disease beliefs of the Santals by the Norwegian missionary and folklorist P. O. Bodding (1865–1938). It was issued in three parts as Volume 10 of the Memoirs of the Asiatic Society of Bengal between 1925 and 1940: part 1, The Santals and disease (1925); part 2, Santal medicine (1927); and part 3, How the Santals live (1940). Compiled from notes Bodding set down over some three decades of residence among the Santals, it records Santal disease categories, the spirits held to cause illness, the medicine man who treated it and the prescriptions and rituals in use.

The work is the principal documentary record of early-20th-century Santal ethnomedicine. Among the several hundred plants it catalogues is the Santal gã̄jã, which Bodding identifies as Cannabis sativa and which appears both as a medicinal ingredient and as an item demanded in a spirit-possession rite. … read more →

Knowledge translation and evidence use in medicinal cannabis policy: An evidence brief on regulation, effectiveness, safety and stakeholder support in Colombia

A knowledge-translation study from the Unit of Evidence and Deliberation for Decision Making at the University of Antioquia in Medellín, reporting how an evidence brief on the regulation, effectiveness, safety and stakeholder support of medicinal cannabis was assembled and put before Colombia's Ministry of Health. Its interest for the corpus is procedural rather than botanical: it documents how research evidence and stakeholder opinion were marshalled into a national cannabis regulatory process, in a producer country whose policy record the wiki otherwise holds through enforcement reporting.
