Probably originating about 1160, the Regimen sanitatis from the medical school at Salerno (where medicine was first treated as a separate science) had greater popular influence than virtually any other medieval medical tract. This collection of very sensible dietary and hygienic precepts was first printed with the famed commentary on the Regimen by Arnald of Villanova. The citation (ISTC no. ir00061000) is one of six undated editions, of which four were issued by Johannes de Westfalia. All were probably printed around 1480-85; no order of priority can be definitely established. English translation by Thomas Paynel, [London, 1535]. See Nos. 49-51. Digital facsimile of the edition printed between 1477 and 1483 from the Universitäts- und Landesbibliothek Düsseldorf at this link.

The first printed book on wine, its production and preservation, translated from the Latin by Wilhelm von Hirnkofen. It discusses the value of wine in diet and as a medication. Wine has been called the oldest documented human-made medicine. Egyptian papyri and Sumerian tablets dating back to 2200 BCE detail the medicinal role of wine. Wine was used variously as a safe alternative to drinking water, as an antiseptic for treating wounds, as a digestive aid, and as a cure for a wide range of ailments including  lethargy, diarrhea and pain from child birth. 

In 1943 medical historian Henry Sigerist issued a facsimile of the first edition, with an English translation and introduction, entitled The Earliest Printed Book on Wine. ISTC no. ia01080000. Digital facsimile of the first printed edition from the Bayerische StaatsBibliothek, München at this link.

The commentary by Gentile da Foligno upon Avicenna's Canon was among the most influential medical texts of the Later Middle Ages. See Roger K. French, Canonical medicine: Gentile da Foligno and scholasticism (Leiden: Brill, 2001).
