Ipecacuanha.
Although several earlier allusions to ipecacuanha have been found, the first being in an account of Brazil by a Portuguese friar given in Purchas's "Pilgrimes" (1625), where the medicine is named Igpecaya and is described as a remedy for the bloody flux, its effective introduction to European medicine was in the year 1686, when Louis XIV bought from Jean Adrien Helvetius the secret of a medicine with which he had performed a number of remarkable cures of diarrhœa and dysentery.

With the consent of the court physician, D'Aquin, Helvetius treated the Dauphin and cured him. As a result the king authorised D'Aquin and his confessor, the Père de la Chaise, to negotiate with Helvetius for the publication
