Ayurveda identified that mind and body as the sites of manifestation of diseases basing on the etiological factors of the diseases and classified as exogenous and endogenous in origin. Visha is considered as one of the external factors for the causation of exogenous disease. All the main classical works on Ayurveda, such as Charaka samhita, Susruta samhita, Astanga Sangraha and Astanga Hridaya deal with drugs, their composition and action in addition to the other aspects of the medical system. Some of the Ayurvedic books known as Kosha & Nighantu granthas like Amarkosha, Dhanvantari nighantu, Kaiyadeva nighantu, Bhavaprakash nighantu, Raj nighantu etc. deal mainly with single drugs, describing their habitat, characteristics and therapeutic action. This paper is an attempt to focus on the information recorded in various classics on vishahara dravya.
