Effects on humans and other mammals

methylergometrine maleate (Methergin)
Main article: Ergotism

The ergot sclerotium contains high concentrations (up to 2% of dry mass) of the alkaloidergotamine, a complex molecule consisting of a tripeptide-derived cyclol-lactam ring connected viaamide linkage to a lysergic acid (ergoline) moiety, and other alkaloids of the ergolinegroup that are biosynthesizedby the fungus. Ergot alkaloids have a wide range ofbiological activities including effects on circulation andneurotransmission.

Ergot alkaloids are classified as:

1. derivatives of 6,8-dimethylergoline and
2. lysergic acid derivatives.

Ergotism is the name for sometimes severe pathological syndromes affecting humans or other animals that have ingested plant material containing ergot alkaloid, such as ergot-contaminated grains. TheHospital Brothers of St. Anthony, an order of monks established in 1095, specialized in treating ergotism victims…
