"Störck is remembered for his clinical research of various herbs, and their associated toxicity and medicinal properties. His studies are considered to be the pioneering work of experimental pharmacology and his method can be regarded as forming a blueprint for the clinical trials of modern medicine. He was convinced that plants regarded as poisonous still had medicinal applications if employed in carefully controlled quantities. Störck was particularly interested in the medical possibilities of plants such as hemlock, henbane, jimsonweed and autumn crocus. His experiments with these plants involved a three-step process; initially used on animals, followed by a personal trial, and finally given to his patients, all the while maintaining a "sliding-scale" approach to determine the optimum dosage" (Wikipedia article on Anton von Störck, accessed 03-2018).
