Write a short note on the famous physician Charaka.
There is considerable disagreement about the period during which Charaka lived.The figures range from before 500 BC to 200 AD, and not much is known about the man. It has even been suggested that the name Charaka was adopted as a non-specific label for wandering physicians. Scholars suggesting the earlier periods note that Charaka is quoted in the works of the famous Sanskrit grammarian Panini (520-460 BC) and Patanjali (circa 250 BC) while those suggesting later periods observe that Chinese Buddhist documents indicate that Charaka was a court physician to King Kanishka (1stand 2ndcenturies AD), a Kushan Buddhist King who ruled a wide region that included parts of India (Mathura), Pakistan (Peshawar and Taxila), Afghanistan (Bagram), and Tibet (Xinjiang in Uygur, China). His relatively modern approach to medicine suggests that he perhaps lived in the 1stand 2ndcentury AD. However, it is also possible that the court physician for King Kanishka was merely a namesake of the ancient physician Charaka. Charaka is credited with re-writing and editing Agnivesha's text, while Charaka's own text was later revised by Dridhbala (Kashmir, 8thcentury AD).This is the document currently available as theCharaka Samhita.It contains 120 chapters and is divided into eight sections. English translations of the original Sanskrit text exceed 1000 pages in length, and the material covered includes anatomy, physiology, diagnosis, and treatment. Dridhbala's is the only surviving text and we do not have access to the original Sanskrit text by Agnivesha, that by Charaka, or translations thereof.
