Medicine for the Material World

open access: yesArchaeometry, Volume 68, Issue 3, Page 434-439, June 2026.
ABSTRACT It is clear that many of the inorganic materials of antiquity have been used both as medicines for human ills and also as agents in technological processes. This paper speculates that there might have been a stronger link between these two functions in the past, based on the concept of “active agents”—materials that are efficacious at curing ...
