A number of therapeutically useful drugs have subsequently been extracted from ergot including ergotamine, pergolide and cabergoline.

The structure of the 5-HT 2B receptor was recently solved in complex with the valvulopathogenic drug ergotamine.

Ergot does not contain lysergic acid diethylamide ( LSD ) but instead contains lysergic acid as well as its precursor, ergotamine.
