Scientists unravel action mechanism of castor oil: Castor oil is known primarily as an effective laxative; however, it was also used in ancient times with pregnant women to induce labour. Only now have scientists at the Max Planck Institute for Heart and Lung Research succeeded in unravelling the mysteries of the action mechanism. A receptor by the name of EP3 on the cells of the intestine and uterus is apparently responsible. This is activated by an ingredient, i.e., Ricinoleic acid (12-hydroxy-9-cis-octadecenoic acid) is an unsaturated omega-9 fatty acid in the oil, see the structure).
