Surgical instruments, including scissors and forceps, were recently found in the tomb of Dr. Xia Quan, who lived in Jizhou province between 1348 and 1411. Researchers from Shanhaiguan North-Western University in China, led by Congcang Zhao, utilized laser technology to analyze residues remaining on the instruments.
Their analysis revealed the presence of aconitin. Aconitin is a compound derived from plants belonging to the Aconitum genus, commonly known as wolfsbane. This substance is frequently referenced in historical Chinese medicinal recipes.
Chemically, aconitin interacts with sodium channels located in the cell membranes of neurons. When administered in precise dosages, it exhibits anesthetic properties. However, due to its inherent toxicity and the significant risk of poisoning, its modern application is rare.
The discovery provides valuable insight into historical medical practices. The identification of aconitin suggests that these ancient surgical tools were associated with medicinal preparations containing this potent alkaloid. The findings underscore the complex relationship between early surgical techniques and the use of natural, yet hazardous, pharmacological agents in traditional medicine.
