Nicolás Monardes, Historia medicinal de las cosas que se traen de nuestras Indias Occidentales (Seville, 1565-1580)

The book that carried American pharmacy into European medicine, written by a physician who never crossed the Atlantic and who interrogated in Seville the men who had. It names the Indian healers who taught the remedies, records the author's own refusal to believe in them, and ends by indicting his countrymen for buying the drugs of New Spain as merchandise without troubling to find out what they were.
