ergot

 [er´got]
the dried sclerotium of the fungus Claviceps purpurea, which attacks rye plants. Ergot alkaloids are used as oxytocics and in treatment of migraine. Consumption of excessive amounts of ergot can cause the toxicity known as ergotism.

er·got

(er'got),
The resistant, overwintering stage of the parasitic ascomycetous fungus Claviceps purpurea, a pathogen of cereal rye that transforms the seed of rye into a compact spurlike mass of fungal pseudotissue (the sclerotium) containing five or more optically isomeric pairs of alkaloids. The levorotary isomers induce uterine contractions, control bleeding, and alleviate certain localized vascular disorders (migraine headaches).
See also: ergotism.
Synonym(s): rye smut

ergot

/er·got/ (er´got) the dried sclerotium of the fungus Claviceps purpurea, which is developed on rye plants; ergot alkaloids are used as oxytocics and in treatment of migraine. See also ergotism.

ergot

(ûr′gət, -gŏt′)
n.
1. Any of several fungi of the genus Claviceps, especially C. purpurea, that infect various cereal plants and form compact black masses of branching filaments that replace the grains of the host plant. Humans and livestock can be poisoned by ingesting ergot-infected grains.
2. The plant disease caused by such a fungus.
3. The dried sclerotia of ergot, usually obtained from rye seed and used as a source of several medicinally important alkaloids and as the basic source of lysergic acid.

er·got′ic adj.

ergot

[ur′gət]
Etymology: L, ergota, a grain fungus
a fungus structure that replaces the seed of rye and other cereal grasses infested with the parasitic fungus Claviceps purpurea. Ergot contains ergot alkaloids, the agents responsible for what was known as St. Anthony's fire in people who consumed the contaminated grain in the Middle Ages. Effects included hallucinations and such intense vasoconstriction in the extremities that portions of the limbs often developed gangrene and fell off before the person died.

ergot

Herbal medicine
A fungus that infects rye, which is the primary source for ergonovine and ergotamine; its use in herbal medicine is confined to haemostasis and strengthening uterine contractions during childbirth.

ergot

One of various fungi of the genus Claviceps , that can grow on rye and other cereal plants and cause the serious condition of ERGOTISM by virtue of its alpha-adrenoceptor stimulating action. Ergot is the source of various valuable drugs such as ERGOTAMINE and ERGOMETRINE. It is also the source of lysergic acid.

ergot

  1. a disease caused by the ascomycete Claviceps purpurea in cereals and grasses.
  2. a SCLEROTIUM forming in place of a grain in a diseased grain head. Ergots contain substances that are poisonous and are sometimes used medicinally.
