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.

Cikitsasarasangraha
The Cikitsāsārasaṅgrahaḥ (Sanskrit चिकित्सासारसंग्रहः, "Compendium of the Essence of Treatment"), also known as the Vaṅgasena Saṃhitā, is a Sanskrit Ayurvedic medical compendium composed in Bengal in the 12th century CE by Vaṅgasena, son of Gadādhara, of Kantikapura. It is counted among the eight complete sangraha (epitome) texts of medieval Indian medicine, alongside the Aṣṭāṅgasaṅgraha of Vāgbhaṭa, the Śārṅgadhara Saṃhitā and the Bhāvaprakāśa.
The work is one of the earliest Indian medical compendia to record cannabis, under the Sanskrit name vijayā (विजया), as a named ingredient in standardised polyherbal formulations. The principal cannabis preparation, Vijayā Cūrṇa, is a twenty-eight ingredient compound described in the chapter on haemorrhoids; additional vijayā preparations appear in the chapters on fevers, sprue and indigestion.
The standard printed Sanskrit edition is the 1891 Calcutta recension prepared by the Bengali pandit Jīvānanda Vidyāsāgara Bhaṭṭāchārya, which runs to 1052 pages and is the source documented on this page. It is in the public domain and freely available through the Internet Archive. read more →
