The earliest treatise dedicated to the general study of plant and animal poisons, including their classification, recognition, and the treatment of their effects is the Kalpasthāna, one of the major sections of the Suśrutasaṃhitā, a Sanskrit work composed before ca. 300 CE and perhaps in part as early as the fourth century BCE. The Kalpasthāna was influential on many later Sanskrit medical works and was translated into Arabic and other languages, influencing South East Asia, the Middle East, Tibet and eventually Europe.
