These eight procedures form the complete foundation of Shalya Chikitsa (surgical treatment) in Ayurveda, as described in the Sushruta Samhita (~500 BCE). Acharya Sushruta's classification preceded modern surgical taxonomy by over two millennia, and every one of these procedures has a direct parallel in contemporary surgery. The source reference for this classification is Su.Su. (Sushruta Samhita, Sutrasthana), Chapter 5.
