Chemical Traces of Aconitine Found on Ming-Era Surgical Tools
A study published in the journal Antiquity has identified chemical residues of aconitine on metal instruments belonging to Xia Quan, a physician from China's Ming dynasty. This marks the first chemical proof that anesthesia was used centuries before the first public demonstration of inhaled narcosis in Boston in 1846. The findings push back the timeline of surgical pain management by half a millennium.
The tools bearing these residues were originally unearthed in 1974 in Jiangyin, a city in Jiangsu Province. Analysis revealed traces of aconitine, a toxin derived from plants in the genus Aconitum (commonly known as monkshood or wolfsbane).
Historical Significance and Broader Implications
The instruments belonged to physician Xia Quan, who lived from 1348 to 1411. The scissors and forceps found in Jiangyin measure just over 12 centimeters in length. Chemical testing showed the tools are 97% iron, with the key marker indicating the presence of aconitine extracted from Aconitum carmichaelii and Aconitum kusnezoffii.
This discovery underscores how much earlier sophisticated medical knowledge existed than previously thought. It demonstrates that medieval Chinese doctors had access to pain-relief methods that could ease surgical procedures. The findings challenge conventional narratives about the history of medicine and anesthesia.

This evidence suggests ancient civilizations possessed knowledge and technologies far ahead of their time, potentially reshaping our understanding of medical and anesthetic development as a whole.
This groundbreaking discovery not only sheds light on ancient anesthesia practices but also aligns with other findings that reveal the advanced medical techniques of early civilizations. For instance, a recent study uncovered evidence of ancient dental surgery performed by Neanderthals, showcasing their remarkable understanding of health and medicine.
