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 →

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.
