Concept of Poison in Ayurveda

Poison is a substance that is harmful to the living organisms in all respects. It can even cause immediate death of the exposed. Ayurvedic authors mention one terminology "BISHA" that has close similarity with "POISON" mentioned in the modern toxicology. A vivid description of Bisha is available in the Ayurvedic classics starting from definition, classification, properties, mode of action, signs and symptoms, treatment etc. The discussion on the route of entry and media through which poison can be given to a targetted human / animal is also attractive. The Ayurvedic authors also have given guidance to the Toxicologists (Bishavaidya) on the procedures of prognostitization of a patient of poisoning. Each and every principle of the Ayurvedic scholars needs study and evaluation through the modern techniques to make the modern socity convinced .
