definition
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.
Chronic poisoning, or ergotism, used frequently to occur amongst the poor fed on rye infected with the Claviceps.
As it is practically impossible to reproduce the symptoms of ergotism nowadays, whether experimentally in the lower animals, or when the drug is being administered to a human being for some therapeutic purpose, it is believed that the symptoms of ergotism were rendered possible only by the semi-starvation which must have ensued from the use of such rye-bread; for the grain disappears as the fungus develops.
There were two types of ergotism.
Traces of ergot were found in his bloodstream as in yours, but not to the degree that should cause hallucinogenic ergotism.
The last-known "epidemic" of ergotism occurred in Lorraine and Burgundy in the year 1816.
