The text may have Buddhist influences, since a redactor named Nagarjuna has raised many historical questions, whether he was the same person of Mahayana Buddhism fame. Zysk states that the ancient Buddhist medical texts are significantly different from both Sushruta and Caraka Samhita. For example, both Caraka and Sushruta recommend "Dhupana" (fumigation) in some cases, the use of cauterization with fire and alkali in a class of treatments, and the letting out of blood as the first step in treatment of wounds. Nowhere in the Buddhist Pali texts, states Zysk, are these types of medical procedures mentioned. Similarly, medicinal resins ("Laksha") lists vary between Sushruta and the Pali texts, with some sets not mentioned at all. While Sushruta and Caraka are close, many afflictions and their treatments found in these texts are not found in Pali texts.
