Researchers have discovered evidence that surgeons in medieval China, during the Ming Dynasty, were performing operations with anesthesia as early as 600 years ago. These medical practitioners utilized plants to induce a state of reduced pain during procedures, effectively neutralizing the plants’ toxic properties through a specific chemical reaction. Modern technology was employed to identify the anesthetic substance used. This finding suggests a sophisticated understanding of pharmacology and pain management existed in China centuries earlier than previously believed. The practice aimed to minimize patient suffering during surgical interventions. This discovery sheds new light on the history of medicine and the ingenuity of ancient Chinese healthcare practices. Further research is expected to reveal more details about the specific techniques and plants employed.
