Hi there, your best areas to search would be in the Materia Medica (Herbal/Homeopathic). You can look into the "The Yellow Emperor's Classic of Internal Medicine (Huangdi Neijing)". Hildegard Von Bingen is a famous herbalist from antiquity who's work is well renowned. Her book is called "Physica". You can also search Nicholas Culpepper (famous English Herbalist 17th c). He is responsible for publishing the first English translation of the Latin Pharmacopeia "A Physicall Directory". You may find that. He also wrote his own Repertory: Complete Herbal and English Physician (This was the authority on herbal medicine use for about 250 years in England). Otherwise look for British Pharmacopeia publications. M. Grieve's Herbal is also a older Materia Medica. There is an online version. I know Ayurveda is an ancient Indian medicine tradition, however I am not familiar with any writings or publications in that tradition.

Thank you for all. It seems those books are valuable for studying traditional medicine, also a good reference as ancient domain knowledge. However, I prefer those specific ancient patients' records with use of traditional medicine, just like the electronic medical records in our hospitals now. With these data, we can study the effectiveness of traditional medicine for patients with specific disorders. Maybe in some libraries, there are some archived data collected by experts?
