Charaka Samhita is an Ayurvedic encyclopedia, especially on medicine. Charaka is written in Sanskrit in poetic style. Poetry form was used mainly for the purpose of memorizing easily. 
Charaka Samhita describes the philosophy and logic on which the Ayurvedic medicinal system is based. Charaka states that science is largely dependent on an intellectual quality which facilitates it to observe and understand the phenomena that was brought into existence by a number of causes. Most part of this extensive work is in a symposium form wherein several groups of Ayurvedic scholars involve in a range of topics for discussion. Well, this proves the fact that the science of Ayurveda is an end result of consistent verification, enhancement and authentication by an intellectual and active community of scholars and physicians.
 
Charaka Samhita focuses on kayachikitsa or internal medicine. The book largely involves the theory of internal fire or the body’s digestive function or in modern terms, internal medicine. From a greater point of view, this extraordinary work is a representation of a particular value of consciousness because it provides a notion that this life is basically a field of pure knowledge and intelligence.
