| Borgognoni, Teodorico | <person> Friar Theodoric of Lucca was a Dominican monk, Bishop of Cervia, and physician to Pope Innocent IV, who taught that suppuration was not necessary for wound healing. Instead of leaving a fresh wound open, Theodoric closed it with sutures, thus avoiding purulency. He was criticised sternly by Guy de Chauliac as a copyist and plagiarist probably because he did not adhere to Galen's teachings. Theodoric wrote: "For it is not necessary that pus be generated in wounds -- no error can be greater than this." He also used an anesthetic concoction for his surgical patients, composed of a mixture of opium, hyoscyamus, mulberry juice, lettuce, hemlock, mandrake and ivy. It was used both as an inhalent and a drink. Lived: 1205-1296. (15 Nov 1997) |
