As nouns the difference between ergotism and ergoline

is that ergotism is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus which infects rye and other cereals, and more recently by the action of a number of ergoline-based drugs while ergoline is a tetracyclic heterocycle whose structural skeleton is contained in a diverse range of alkaloids, including some psychedelic drugs, and whose derivatives are used clinically for vasoconstriction and in the treatment of migraine and Parkinson's disease.
