A few works of interest, since this is a medieval-inspired setting: St. Hildegard of Bingen's Physica
, which is conveniently available in ebook form. She also wrote one called Causes and Cures
, which seems to only exist in print editions for now.
You might also want to look into Galen
and Avicenna / Ibn Sina
, who also wrote some fairly major works on the subject of medicine that were widely referenced during the period. You can probably find a translation or two in the public domain if your Google-fu is up to snuff.
Of course, since they were actually written in the medieval period or earlier, I won't vouch for perfect scientific accuracy, but they might be useful for understanding what people in those times thought would cure their maladies, and many actually worked quite well.
