Charaka Samhita: The Complete Guide — Sthana by Sthana
The Charaka Samhita (चरक संहिता) is the oldest complete textbook of Ayurvedic internal medicine and one of the most influential medical works ever composed. Written and refined between roughly 400 BCE and 200 CE, its 120 chapters set out the principles that still define Ayurveda today: the three doshas, the six tastes, the science of digestion and rejuvenation, and a vision of medicine whose first duty is to protect the health of the healthy.

What Is the Charaka Samhita?
Tradition records three layers of authorship. The sage Agnivesha composed the original treatise from the oral teachings of his master Punarvasu Atreya. The physician Charaka later revised and expanded that work so thoroughly that it has carried his name ever since. Finally, Dridhabala of Kashmir restored the chapters that time had scattered, completing the text we read today.
Together with the Ashtanga Hridaya and the Sushruta Samhita, it forms the Brihat Trayi (बृहत्त्रयी) — the "Great Trio" of classical Ayurvedic literature. Of the three, the Charaka Samhita is the authority on internal medicine (Kayachikitsa): diagnosis, diet, herbs, rejuvenation and the physician's craft.

Why Read a 2,000-Year-Old Medical Text?
Because its questions are still our questions. The Charaka Samhita's opening chapter is about people made unwell by settled, comfortable, indoor living — and its answers begin with food, routine, the senses and self-honesty rather than with medicines. Its doctrine that like increases like and opposites heal remains the most practical self-care heuristic ever stated. And its insistence that prevention outranks cure is only now being rediscovered by modern healthcare.
Every product we make at Ayurveda Hub stands inside this tradition — formulated from the classical sources, manufactured in our village unit, and explained without exaggeration. The series exists so you can meet the source itself.
