The Charaka Samhita is one of the foundational texts of classical Ayurveda and the text most frequently cited on this site. It sets out a complete system of medicine — diagnosis, anatomy, treatment, diet, daily routine and medical ethics — rather than a simple list of remedies.
Origins and Authorship
The text has a layered history rather than a single author. The teaching began with the sage Atreya. His student Agnivesha put it into written form first, as the Agnivesha Samhita. Charaka later revised and expanded it so substantially that the text came to carry his name. Centuries after that, Dridhabala edited portions further and added 17 chapters of his own, producing the version read today.
Most scholars place the surviving text around the 1st century CE, though its ideas draw on an older oral teaching tradition that predates this written form.
The Eight Sthanas
The text is organized into eight sections (Sthanas) across 120 chapters:
| Sthana | Chapters | Focus |
|---|---|---|
| Sutra Sthana | 30 | General principles, philosophy, prevention, and foundational concepts |
| Nidana Sthana | 8 | Causes, symptoms and diagnosis of major diseases |
| Vimana Sthana | 8 | Taste, diet, physician training, and methodology |
| Sharira Sthana | 8 | Human anatomy, embryology, and physiological and psychological constitution |
| Indriya Sthana | 12 | Diagnosis and prognosis, particularly sensory and mental indicators |
| Chikitsa Sthana | 30 | Detailed treatment methods for specific conditions |
| Kalpa Sthana | 12 | Preparation of medicines, particularly for purification therapies |
| Siddhi Sthana | 12 | Execution, outcomes and complications of therapeutic procedures |
Citations on this site, such as "Charaka Samhita, Sutrasthana Chapter 26" or "Chikitsa Sthana 26/267–268," refer to this eight-part structure, pointing to the exact section a claim is drawn from.
Why This Text Carries So Much Weight
The Charaka Samhita treats prevention with the same seriousness as cure, which is uncommon among texts of its era. It covers diagnosis, anatomy, embryology, diet, daily routine (Dinacharya), purification therapy (Panchakarma), and medical ethics, including how much recovery depends on physician, patient and caregiver working together.
Charaka Samhita is one of the Brihattrayi — the "great three" texts of classical Ayurveda, alongside Sushruta Samhita and Ashtanga Hridaya.
