An Historical Relation of the Island Ceylon (Knox 1681)
An Historical Relation of the Island Ceylon, in the East Indies is a book by Robert Knox (1641–1720), published in London in 1681 by Richard Chiswell, the printer to the Royal Society. The book describes Knox's nineteen years of captivity in the Kingdom of Kandy (1660–1679) and contains the earliest known account by an Englishman of using cannabis medicinally in Ceylon. Knox's sample of the plant, which he called bangue or Indian hemp, was later the subject of the first controlled experiment with cannabis in European scientific history, conducted by Robert Hooke at the Royal Society in December 1689.
The cannabis passage appears in Knox's account of his escape attempts of the 1670s. He describes the dried leaf beaten to powder with jaggery and eaten on an empty stomach as an antidote to the fevers and ague caused by drinking from stagnant cattle ponds. Knox records the plant under the Portuguese-derived name banga (from bhang), indicating that it was widely enough known in the Kandyan kingdom for him and his companion to readily obtain and learn to use it. Together with the brief mention of "a little hemp" by the Portuguese Jesuit Fernão de Queyroz, the Relation is one of the two principal European accounts of cannabis use in seventeenth-century Ceylon. read more →

Cannabis eradications
We are witnessing the rapid disappearance of traditional cultivation knowledge and genetic diversity in cannabis. These landrace populations represent thousands of years of natural and human selection, containing unique genetic traits and chemical profiles. Systematic documentation and conservation efforts can serve as a bridge, preserving irreplaceable genetic heritage while supporting traditional communities and advancing our understanding of this remarkable plant.
