Was the Four Humours Theory of Medicine good enough to cure *some* disease?
I was thinking about how the four humours theory was used in much of the Ancient and Medieval world, and though I know of its obvious incorrectness, and resulting horrible procedures like Leeching and Cupping, I was wondering if it was better than nothing at all? In the same sort of a way a broken clock is right twice a day.
To simplify it, if I had a random disease, would I be better seeing a medieval doctor or doing nothing?
