Origin and Evolution of Sangyaharan (Anaesthesia) in Ancient India

The concept and practice of Sangyaharan (Anesthesia), widely believed to be a Western innovation of the 19th century, finds its earliest roots and most sophisticated origins in ancient India; Long before the advent of modern anesthetic techniques, Acharya Sushruta (circa 600 BCE), known as the Father of Surgery and Plastic Surgery, described and implemented to keep the patient under sedation for painless surgical procedures and pain management as recorded by Acharya Sushruta in his Sushruta Samhita. This foundational Ayurvedic text outlines the use of Madyapanam (intoxicating drinks such as wine) combined with herbal medicines (sedatives) including Cannabis sativa (Bhang), Acorus calamus (Vacha), Nardostachysjatamansi (Jatamansi), Hyoscyamus niger (ParasikaYavani), and others to induce insensibility and pain relief. Sushruta’s pioneering approach to pain management not only enabled over 300 types of surgical operations—including rhinoplasty, cataract extraction, and intestinal repairs—but also introduced the first systematic preoperative, operative, and postoperative protocols emphasizing patient comfort, safety, and consent.
This review traces the evolution of anesthesia from its early evidences in ancient civilizations— Mesopotamian, Egyptian, Chinese, Greek, and Indian—to its modern refinement through the use of ether, chloroform, and nitrous oxide in the 19th century. The manuscript underscores that Acharya Sushruta’s Sangyaharan laid the conceptual and practical foundation for modern anesthesiology. Through meticulous documentation and use of natural sedatives, analgesics, and nerve-desensitizing agents, ancient Indian medicine achieved highly advanced pain management practices that predate Western scientific anesthesia. Thus, the study establishes India’s crucial and pioneering role in the origin and evolution of anesthesia as a medical discipline.
