Gregorio López, Tesoro de medicinas — a layman's remedy book vetted in print by physicians

A remedy book put together in New Spain by a hermit who was not a physician, its cures tried at the hospital of Huaxtepec and keyed to Nahuatl plant and bird names. The Madrid 1708 printing read here carries something rarer than the remedies: printed notes in which two licensed physicians qualify the hermit's prescriptions and, in places, refuse to approve them at all — inside an edition openly published to advance his canonisation.
