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.

Colloquies on the Simples and Drugs of India (1563)
The Colóquios dos Simples e Drogas e Coisas Medicinais da Índia (Colloquies on the Simples, Drugs and Materia Medica of India) is a pharmacological treatise by the Portuguese Jewish physician and naturalist Garcia da Orta (c. 1490–c. 1570), published at Goa on 10 April 1563 by the printer João de Endem. The work consists of fifty-seven colloquies on the drugs, spices and medicinal plants of India, written as dialogues between Orta and a fictional interlocutor, Dr. Ruano. It was among the first books printed in India and is recognised as the foundational text of European tropical pharmacology.
Orta arrived at Goa in 1534 and remained in India for the rest of his life, building his knowledge through direct observation and consultation with local practitioners across Gujarat, the Deccan, Kerala and Ceylon. The Eighth Colloquy on Bangue (cannabis) is the earliest detailed European eyewitness account of cannabis preparations and use in India. It distinguishes preparations already established in sixteenth-century South Asia (bhanga, ganja, sidhi, charas, majum) and documents use across social classes, from sultans to servants. read more →
