Linguistics
Semantic Notes
The word primarily denotes a specific biological entity (the fungus/sclerotium). Its extended meanings relate to its medical applications and its historical role in epidemics (St. Anthony's Fire). It is not used metaphorically in modern general language.

FAQ
Frequently Asked Questions
Yes, indirectly. Lysergic acid, a precursor to LSD, is derived from ergot alkaloids. However, ergot itself is not a recreational drug and is highly toxic.
No. Ergot is poisonous. Ingestion can cause ergotism, a serious condition with symptoms ranging from convulsions and hallucinations to gangrene, historically known as St. Anthony's Fire.
Modern grain cleaning and monitoring practices have made ergotism extremely rare in developed countries, but fungal contamination remains a concern in agriculture.
Purified ergot alkaloids, like ergometrine, are used in obstetrics to contract the uterus and control bleeding after childbirth. Ergotamine is used to treat severe migraines.
