Sushruta Samhita

What the Sushruta Samhita is

The Sushruta Samhita is one of the foundational texts of Ayurveda, and the one most concerned with surgery. The word samhita means a collection or compendium, and the text gathers the teaching attributed to Sushruta, a teacher of the surgical tradition. It is written in Sanskrit, in the dense verse-and-commentary form of the classical texts.

Within Ayurveda, surgery is called Shalya Tantra, and the Sushruta Samhita is its great reference. Where the Charaka Samhita is remembered above all for medicine and the inner workings of the body, the Sushruta Samhita is remembered for the work of the hand: instruments, procedures, and the close knowledge of the body that surgery demands.

Its place in the tradition

Ayurveda counts three great classical texts together as the Brihat Trayi, the “great three”: the Charaka Samhita, the Sushruta Samhita, and the Ashtanga Hridayam of Vagbhata. The Sushruta Samhita is the second of these. Its standing is bound up with the surgical tradition it carries, which is more fully set out here than anywhere else in the classical corpus.

The text comes down to us in a redaction that was shaped over a long period, and a later section, the Uttara Tantra, was added to round it out into a more complete work. Tradition traces the surgical teaching itself back to the lineage of Dhanvantari, the figure revered in the tradition as the patron of healing.

How the text is arranged

The Sushruta Samhita is divided into sections, called sthanas, each with its own concern.

The Sutrasthana lays the foundations: what Ayurveda is, the eight branches of the tradition, the qualities expected of a surgeon, and the long, famous enumeration of surgical instruments, the blunt instruments (yantra) and the sharp ones (shastra).

The Nidanasthana deals with the understanding and classification of conditions, with particular attention to those the surgical tradition concerned itself with.

The Sharirasthana is the text’s anatomy. It is the most detailed account of the body in the classical literature, and it includes the celebrated description of the marma points, the vital sites on the body, which the tradition maps by location and significance.

The Chikitsasthana sets out the management of conditions, including the careful handling of wounds for which the text is well known.

The Kalpasthana treats Agada Tantra, the classical knowledge of poisons and their antidotes.

The Uttara Tantra, the supplementary section added later, ranges more widely, taking in the care of the eyes, ears, nose and throat, the care of children, and general medicine, so that the whole becomes a rounded compendium.

What it is remembered for

A few things give the Sushruta Samhita its lasting reputation.

It describes a method of reconstructing the nose using a flap of the patient’s own skin, a technique later known as the “Indian method” and much studied in the history of surgery.

It sets out a teaching method for surgery built on practice. Students learned cutting on gourds, stitching on cloth and skin, and probing on hollow stems, before they ever worked on a person, an approach to training that the text describes with unusual care.

It gives the definitive classical account of the marma points, the vital sites of the body, a map that the tradition has used ever since.

And, fitting for a surgical text, it gives unusual weight to Rakta, the blood, treating it almost as a fourth principle alongside the three doshas of Vata, Pitta and Kapha.

Why it still matters

For students of Ayurveda the Sushruta Samhita remains the primary source for the surgical side of the tradition, and its anatomy and its account of the marma points are still studied directly. Beyond Ayurveda, the text holds an honoured place in the wider history of surgery, as one of the earliest works to set out surgical knowledge in a systematic way.
