Some of the more useful drugs are a product of “traditional medicine”. Colchicine for gout, digitalis, aspirin. The best current drug for falciparum malaria is the result of project 523, where the PLA (at the request of Ho Chi Minh) had people dig through old Chinese herbal manuals. Communism and Taoist magic – the royal road to drug development. Tu Youyou received the Nobel prize for this work in 2015; truly, there are other ways of knowing.
Which suggests that it might be worthwhile checking out other versions of traditional medicine. Sure, we should revisit classical medicine – reread Dioscorides,. Maybe we’ll all be swigging theriac in a few years.
A virgin medical tradition, one that hasn’t already been mined out, might be more promising. The Sassanid empire had its own intellectual tradition – much of which was lost in the Arab conquest. Not many of their works survive. We know, though, that they had their own medical tradition, centered at Gundeshapur, with a teaching hospital, library and an academy of learning. Gondeshapur gave refuge to Syriac Christians and Hellenistic philosophers. Indians and Chinese visitors translated Chinese and Indian texts on mathematics, astronomy, and medicine.
It is possible that manuscripts of some of the lost works of Sassanid civilization still exist – in dry caves, for example, like the Dead Sea Scrolls. Worth a look.
