While prowling around online I finally rediscovered a page that has some excerpts from the Codex Badianus on it. The Codex Badianus, also known as the Codex Barberini or the Libellus de Medicinalibus Indorum Herbis, was the first book of herbal medicine published in the Americas. It was written by Martin de la Cruz, a young Nahua herbal physician of good repute, and published in 1552. The University of Virginia has a nice little exhibit about the codex, including several traditional Aztec medical recipes and photos of some of the plants. If you’d like to learn a bit more about the codex itself and some general info about Aztec medicine, including a few more recipes, Mexicolore has a handly little introductory article on it to whet your appetite. Finally, if you’re curious to learn more at a more technical level, I even found some professional journal articles on the subject on PubMed. Don’t forget to check the References list at the bottom of the page for more articles on Aztec medicine available on PubMed.
