What effect does ergot have when ingested?

Ergot is derived from a fungus that grows on certain grains, particularly rye, and contains compounds known as ergot alkaloids. These compounds have significant physiological effects, particularly on the nervous system. When ingested, ergot can lead to a range of symptoms including vasoconstriction, and most notably, it is known to have hallucinogenic properties due to its influence on serotonin and dopamine receptors in the brain. This results in the experiences of hallucinations, which can be visual or auditory in nature.

The other effects listed, such as cough suppression, psychostimulation, and increased appetite, are not characteristic of ergot ingestion. Cough suppression is more typically associated with certain medications like antitussives, while psychostimulation relates to substances that enhance alertness or energy, such as caffeine. Increased appetite usually pertains to substances that affect metabolism or hormone levels in ways that stimulate hunger. Therefore, the primary and most well-known effect of ergot ingestion remains its ability to induce hallucinations.
