What to know about History of Medicine

Researchers used stimulated Raman scattering microscopic imaging to identify aconitine residues on surgical tools from a Ming dynasty tomb. The findings provide the first direct physical evidence of the use of a toxic plant-derived anesthetic in ancient Chinese surgery, complementing existing historical texts.

Why it matters

From Roman cosmetics to Andean psychoactive plant preparations, archaeologists often apply scientific methods to identify pharmaceutical residues from ancient civilizations.

Common ground

However, conventional techniques are difficult to apply to ancient Chinese medical residues, which are rarely preserved and often fail to meet minimum sample requirements for identification.
