<p style="text-align:justify;">Among the Ashtangas, ''agada tantra'' (toxicology) stands separate in its concept, clinical approach, management and result. This is the only chapter which guides us in the management of poison and the conditions of poisoning. As we all know ''visha'' and ''visha chikitsa'' requires a special mention in any medical system. It is rightly justified by the following facts:

Among the Ashtangas, ''agada tantra'' (toxicology) stands separate in its concept, clinical approach, management and result. This is the only chapter which guides us in the management of poison and the conditions of poisoning. As we all know ''visha'' and ''visha chikitsa'' requires a special mention in any medical system. It is rightly justified by the following facts:

 

Treatment of poisoning is an emergency and should be managed as a house on fire, earlier its extinguished, lesser the damage, and the result for the effort of ''vaidya'' is immediate when compared to the other disorders. This chapter deals with study of the poison, its origin and criterion of classification. The group of ''sthavara'' (poisons of plant origin, minerals and metal, poison of immobile origin or vegetable poison) and ''jangama'' (poisons of animal origin) are described. A special category called ''kritrima visha'' (artificial poison) with a significant role for a good physician in treating severe cases. ''Dushivisha'' (slow poisons) is explained in a sentence but, has lot of hidden meaning and is a treasure in innovating the treatment skills of a physician. Various treatment methods for the poisons and ''chaturvimshati upakrama'' (24 fold treatments) is a special contribution of Charak. Medicines as a single drug and as a combination are told as remedial measures and also as symptomatic treatments as per the requirement of condition are described. Together with this, ''jangama vishas'' (poison of animal origin) and specific approach for their management are very systematically mentioned.

''Laghu'' (lightness for digestion), ''ruksha'' (dryness), ''ashu'' (rapid), ''vishada'' (non sliminess), ''vyavayi'' (which pervades whole body before getting digested), ''tikshna'' (sharply acting), ''vikashi'' (causing looseness of joints by diminution of [[dhatu]])'', sukshma'' (subtleness), ''ushna'' (hot), and ''anirdeshya rasa'' (indistinct taste)- these are the ten properties of poison according to the expert ''vaidyas''.

Because of dryness property, [[vayu]] gets aggravated; due to hot property, [[pitta]] gets vitiated; subtleness leads to vitiation of [[rakta]]; Due to ''avyakta rasa'' (indistinct taste), [[kapha]] is vitiated;  due to rapidly acting, it quickly permeates through the nutrient fluid; vyavayi [[guna]] spreads it throughout the body instantaneously. Tikshna [[guna]] (sharply acting) property causes injury to marmas, vikashi [[guna]] results in death of the patient. Due to laghu [[guna]] it becomes difficult to manage therapeutically; because of vaishadya [[guna]], it pervades all over the body with [[dosha]] without any obstruction in circulation. Depending upon the location of [[dosha]] and [[prakriti]] of patient, ''visha'' produces several other complications. [24-27]

The ten [[guna]] of ''visha'' with their impact on the [[dosha]] and the body are dealt in this section. Some [[guna]] can be interpreted as follows: Sookshma [[guna]] has a property of ''vivarana'' i.e.; to spread which makes the [[rakta]] to spread all over and make the ''visha'' reach all over the body. [[Kapha]] and ''visha'' have the same origin from ''jala'' (water) and also the ''avyakta rasata'' leads to intrude into the ''anna rasa'' and spreads fast. Vyavayi [[guna]] is responsible for the quick spreading of ''visha'' as like a drop of oil spreads on water surface. ''Taikshnya'' is responsible for ''marmaghna'' effect. Basically ''marma'' is ''saumya'' in nature. The ''vishada guna'' of ''visha'' makes it unsticky and there by not allowing getting it adhered at single place. The teekshna [[guna]] of ''visha'' destroys it and causes the ''marmaghna'' effect. It is very difficult to keep a ''laghu dravya'' stagnant. It keeps on changing its form or function. So it becomes very difficult to treat ''visha'' that is ''laghu'' and constantly changing its site of action in the body. Sushruta has also attributed the effect of poisons corresponding to its [[guna]]. The illustration is precise and understandable.<ref>Sushruta.
