Abstract

The aim of the present essay is to analyze the work performed at the National Medical Institute with a group of plants remarkable for containing significant psychoactive principles. The studies on the NMI conducted up to the present time did not analyze in depth the place those substances had in the Institute’s research agenda. For that reason we sought to identify the medicinal plants studied at NMI together with their active principles, the diseases to which they were experimentally applied, and the procedures used to study them. To illustrate that process we present two particular cases: peyote J.M. Coult) and white sapote.
