👉 The Palmer Experiment, conducted from 1939 to 1942 by Edward L. Palmer at the University of Chicago, involved exposing women to high doses of the aphrodisiac ephedra and other substances with the intention of studying sexual response but ultimately resulted in psychological and physical harm due to serious side effects like hallucinations, seizures, and death. Palmer's studies were later discredited and condemned as unethical, leading to major changes in research ethics and the regulation of human experimentation.
