Papaver somniferum in seventeenth century (Italy): archaeotoxicological study on brain and bone samples in patients from a hospital in Milan

Abstract

AbstractIn this paper, we present the results of toxicological analyses of preserved brain tissue and bone samples from the remains of the seventeenth century patients of the Ospedale Maggiore, the main hospital in Milan and one of the most innovative hospitals in Europe from the Renaissance period. Beneath it, the crypt functioned as the burial place for the deceased of the hospital. In this multidisciplinary study of the remains, toxicological analyses in particular were performed with HPLC–MS/MS on different biological samples from nine individuals. Anthropological, paleopathological, histological, radiological examinations and radiocarbon dating were also carried out. As a result, archeotoxicological analyses revealed the presence of codeine, morphine, noscapine and papaverine, derived from Papaver somniferum, a plant present in the hospital pharmacopeia used as a narcotic, analgesic, astringent, coagulant, and antitussive agent. Such analyses have shed light on the pharmacological therapies administered to the patients near the time of death and have implemented our knowledge of medical treatment and drug administration in the 1600’s.
