Charaka Samhita — Ayurvedic Practice Guide

Full title: Charaka Samhita (चरक संहिता) — “Compendium of Charaka” · Author: Attributed to Maharishi Agnivesha, revised by Acharya Charaka, further redacted by Dridhabala · Era: Estimated 2nd century BCE (original), 2nd century CE (Charaka revision), 4th–5th century CE (Dridhabala additions) · Language: Sanskrit

The Charaka Samhita is the most authoritative and comprehensive text of Ayurvedic internal medicine (Kayachikitsa). It is the foundational pillar of the Brihat Trayi — the “Great Triad” of classical Ayurvedic texts — and remains the primary reference for Ayurvedic education, practice, and research worldwide. The text represents a systematic treatise on health, disease, diagnosis, and treatment, grounded in a philosophical framework that integrates Samkhya, Vaisheshika, and Nyaya philosophies.

Historical Context

The text has a layered history spanning several centuries. The original teachings are attributed to Lord Atreya (Punarvasu Atreya), who taught at the legendary university of Taxila. His student Agnivesha composed the first written version, known as the Agnivesha Tantra. This was subsequently revised and expanded by Acharya Charaka, whose version became authoritative. Approximately 17 chapters of the final two sections were lost and were later reconstructed by Dridhabala (4th–5th century CE) based on other available sources.

Structure — Eight Sthanas (Sections)

1. Sutra Sthana (30 chapters) — General Principles

The foundational section covering the entire philosophical and theoretical framework of Ayurveda. Topics include: definition of Ayurveda, Tridosha theory, Panchamahabhuta, tastes (Rasa), diet and nutrition principles, daily and seasonal routines (Dinacharya and Ritucharya), the eight branches of Ayurveda, properties of foods and drugs, and the duties and ethics of a physician.

2. Nidana Sthana (8 chapters) — Diagnosis/Pathology

Covers the diagnostic methodology: Nidana (causative factors), Purvarupa (prodromal symptoms), Rupa (cardinal symptoms), Upashaya (exploratory therapy), and Samprapti (pathogenesis). Detailed descriptions of major diseases including Jwara (fever), Raktapitta (bleeding disorders), Gulma (abdominal tumours), Prameha (urinary disorders), and Kushtha (skin diseases).

3. Vimana Sthana (8 chapters) — Specific Knowledge/Measurement

A unique section covering: Rasa Vimana (study of tastes and nutrition), Trividha Roga Vishesha Vijnaniya (methodology for understanding disease), Janapadodhwamsa (epidemics and community health), Rogabhishagjitiya (the four pillars of treatment: physician, drug, attendant, patient), and detailed methodology of clinical examination and research.
