The Estrogenic and Uterine-Stimulating Activity of Asclepias Tuberosa. A Preliminary Investigation

Abstract

The fluidextract of Asclepias tuberosa was found to contain substances estrogenic to castrate rats. A method for separating these substances is proposed. The fluidextract was also found to exert an appreciable oxytocic-like action upon the uteri of several species of laboratory animals both in vitro and in vivo. The literature on Asclepias tuberosa is reviewed.
