What is Ergot?

Ergot is a fungus that infects various grains, especially rye, and produces toxic alkaloids. It has been known for centuries for its effects on humans and animals.

History of Ergot

Ergot has a dark history involving outbreaks of ergotism, also known as St. Anthony’s Fire, which caused symptoms like gangrene, hallucinations, and convulsions. The Salem Witch Trials and other historical events have been linked to ergot poisoning.

Effects of Ergot

Ergot alkaloids are vasoconstrictors, causing blood vessels to constrict, leading to reduced blood flow and potential gangrene. They can also affect the nervous system, causing hallucinations and other mental disturbances.

Modern Uses of Ergot

While ergot is toxic, its derivatives have found use in medicine, particularly in the treatment of migraines. Ergotamine, a compound derived from ergot, is used in migraine medications to constrict blood vessels and alleviate symptoms.
