I would like to read about ancient medicine, where do I start?

Hi, I am curious about ancient medicine and treatments that we still use today (e.g., honey for curing wounds and burns, boiling leaves/herbs for cough, wounds etc.), however I am not sure where to start.

I would also like to read a book of old recipes of remedies like this one I have read here:

For the evacuation of the belly:
Cow’s milk, 1; .grains, 1; honey 1; mash, sift, cook; take in four portions.

To remedy the bowels:
Melilot (?), 1; dates, 1; cook in oil; anoint sick part.

To refresh an aching head:
Flour, 1; incense, 1; wood of wa, 1; waneb plant, 1; mint (?), 1; horn of a stag, 1; sycamore (?) seeds, 1; seeds of [ (?)], 1; mason’s plaster (?), 1; seeds of zart, 1; water, 1; mash, apply to the head.

To renew bowel movements in a constipated child:
An old book, boil in oil, apply half on the belly to reestablish evacuation.

I have found a PDF of these remedies but they are not in English. Any ideas what books should I read? Thank you very much.
