Tractado brebe de medicina (Mexico, 1579 and 1592)

A doctor turned Augustinian friar wrote a home-medicine book for people the medical profession did not reach — "la gente pobre y ausente que carece de socorro de médicos", in Indian villages and country estates. The viceroy's privilege of 1592 says so in as many words. Four editions in thirty-one years, five books ending in anatomy, and a materia medica that a later bibliographer found to be almost entirely Mexican plants.
