Ergocristine is an ergopeptine and one of the ergot alkaloids. It was used as precursor in the manufacture of LSD as an alternative for the controlled substances ergotamine and ergometrine by various LSD manufacturers, including William Leonard Pickard. The usage of ergocristine by Pickard alerted the DEA and the DEA proposed controlling the chemical as an official precursor for LSD manufacture.
