By royal permission in January 1570, Philip II sent the teachers doctors to provinces beyond the seas. These doctors examined the candidates for doctors and also compiled information regarding the practice of surgery, herbal medicine, and everything that contributed to the health of the vassals. In New Spain, the royal court of master doctors was quickly formed, in addition to supervising the medical and astrology talks at the university, was in charge of giving healing and licensing practices to inmates. They were also about charlatans and scammers. Around the eighteenth century, the fame of the "Indian Doctor" had spread throughout the province of Valladolid, currently the state of Michoacan, Mexico. His methods based on scientific experiments were so praised that the authority of the master doctors diminished. The humble doctor refused to be examined and was arrested and taken to the city.
The examination of the Indian Doctor would be public and in the precinct of the main hall of the university. This fact brought many spectators wishing to attend the challenge between institutional science and traditional priests. The faculty wore gowns and gowns, their graduation attire, and honoring their erudition by quoting authors in Latin and referring to what of course they knew the Indian Doctor was ignorant of. Humbly and standing as if he were a convict, the man from Patzcuaro in Valladolid answered the unfair questions saying "Have me patience", which brought smiles of superiority and satisfaction to the faces of the teachers. Then the Indian took something from his chest and said, "Do me a favor, and smell this herb on my breast." The scornful doctors asked him with contempt for the qualities of the herb in Latin and the Indian smiled inside because he could not respond in such a refined language. Instantly the doctors began to have unstoppable nosebleeds, to which the provincial man advised: "Now your mercenaries are from that blood that comes out of your nostrils." In the course of time, his pride changed into a silent plea. The pale and horrified speakers of Latin could not object to anything the Indian Doctor did, who slowly pulled out another herb differently and kindly, made the astonished men who were bleeding smell the grass and the blood stopped. The Royal Court of Master Doctors granted the license to the humble herb.
