Ergot (/ ˈ ɜːr ɡ ə t / UR-gət) or ergot fungi refers to a group of fungi of the genus Claviceps.. The most prominent member of this group is Claviceps purpurea ("rye ergot fungus"). This fungus grows on rye and related plants, and produces alkaloids that can cause ergotism in humans and other mammals who consume grains contaminated with its fruiting structure (called ergot sclerotium).
Ergot is a fungus that can grow on grains such as rye and wheat. It produces toxic alkaloids that can cause symptoms like dizziness, convulsions, and psychosis. It was used as medicine to induce childbirth and treat migraine, but also caused harm and harmless events in the past. Learn more about the history, causes, diagnosis, and treatment of ergot poisoning.
Ergotism is a rare but serious condition caused by eating food contaminated with a fungus called C. purpurea. It can cause gangrene, convulsions, hallucinations, and other symptoms. Learn how ergot is used for medicine and how to prevent and treat ergotism.
Ergotism (pron. / ˈɜːrɡətˌɪzəm / UR-gət-iz-əm) is the effect of long-term ergot poisoning, traditionally due to the ingestion of the alkaloids produced by the Claviceps purpurea fungus—from the Latin clava "club" or clavus "nail" and -ceps for "head", i.e. the purple club-headed fungus —that infects rye and other cereals, and more ...
Ergot is a fungus that grows on rye and other grasses and has been used as medicine, but it is unsafe and can cause poisoning. Learn about ergot's history, uses, side effects, precautions, and interactions with other medications.
Ergot is a fungal infection that affects rye and other grains, causing the formation of poisonous sclerotia. It can also cause ergotism, a serious condition in humans and animals, and is the source of some drugs and LSD.
The ergot fungus contains a number of highly poisonous and psychoactive alkaloids, including lysergic acid (LSD), which was synthesized from the ergot fungus in 1938 by chemist, Albert Hoffmann. Ergot poisoning is a proposed explanation of bewitchment. Most historians today believe that the witchcraft trials that led to thousands of deaths and ...
The ergot diseases of grasses, caused by members of the genus Claviceps, have had a severe impact on human history and agriculture, causing devastating epidemics.However, ergot alkaloids, the toxic components of Claviceps sclerotia, have been used intensively (and misused) as pharmaceutical drugs, and efficient biotechnological processes have been developed for their in vitro production.
Ergot also refers to the typically elongated fungal structure, technically known. as a sclerotium (Figure 1). Claviceps is a unique group of fungi, which infect only the ovaries of grasses, replacing what would normally be a seed with a sclerotium. There are some 40 known species of Claviceps.
Claviceps purpurea is an ergot fungus that grows on the ears of rye and related cereal and forage plants. Consumption of grains or seeds contaminated with the survival structure of this fungus, the ergot sclerotium, can cause ergotism in humans and other mammals. C. purpurea most commonly affects outcrossing species such as rye (its most common host), as well as triticale, wheat and barley.
Ergotism, also known as St. Anthony's fire, was a devastating condition that caused convulsions, hallucinations, and gangrene. Learn how medieval Europeans coped with this scourge, and how it was linked to the saint and his relics.
Ergot is a fungal disease that produces alkaloid toxins that reduce blood flow in mammals. It can cause convulsions, hallucinations, gangrene, and death. It affects wild and cultivated grasses, as well as small grain crops such as wheat, oats, barley and especially rye. Learn how to identify, manage, and prevent ergot from this web page by UW Extension experts.
The Yorck Project (Public Domain) St. Anthony's Fire (SAF) is an illness brought on by the ingestion of fungus-contaminated rye grain causing ergot poisoning (ergotism). The disease's common name derives from the medieval Benedictine monks dedicated to that saint who offered treatment to sufferer's, sometimes using relics of the saint to do so.
For many years, ergot alkaloids have been considered both a problem to be mitigated and a potential medical cure. These compounds have been primarily studied in the medical/pharmaceutical [] and agricultural fields [].Depending on one's perspective, the impact that ergot alkaloids have had on the progress of human medicine and livestock production can be either positive or negative.
Ergot poisoning is a type of illness associated with the ingestion of alkaloids produced by the fungi Claviceps purpurea (C. purpurea). Claviceps purpurea is a fungus classified under the fungi genus Claviceps. This specific type of fungus is found on rye, and also on crops like wheat and barley. In addition, Claviceps purpurea can effect ...
LSD, potent synthetic hallucinogenic drug that can be derived from the ergot alkaloids (as ergotamine and ergonovine, principal constituents of ergot, the grain deformity and toxic infectant of flour caused by the fungus Claviceps purpurea ). LSD is usually prepared by chemical synthesis in a laboratory. Its basic chemical structure is similar ...

Ergot-derivative-containing drugs are used to treat migraine and cluster headaches that are not relieved by other pain relievers. They can cause serious side effects such as blood vessel constriction and nausea, and are available only by prescription.
In the past centuries consumption of bread made of ergot-infected flour resulted in mass poisonings and miscarriages. The reason was the sclerotia of Claviceps purpurea (Fr.) Tul.—a source of noxious ergot alkaloids (ergotamine and ergovaline). The authors have searched the 19th century medical literature in order to find information on the following topics: dosage forms of drugs based on ...
Ergot on a heavy horse with feathers. The ergot is a small callosity ( Calcar metacarpeum and Calcar metatarseum) on the underside of the fetlock of a horse or other equine. Some equines have them on all four fetlocks; others have few or no detectable ergots. In horses, the ergot varies from very small to the size of a pea or bean, larger ...

However, the standard history, according to the accounts of his wife andskin rash. The suggestion of ergot poisoning was ruled out due to England having much less rye (the main cause of ergotism) than the rest of Europe.
