The choline compounds, widely dispersed in nature, have been obtained from many vegetables and organic extracts as well as from certain drugs (especially ergot). The cholines may be considered to be quarternary ammonium bases; they produce two sets of actions: a "muscarine" effect and a "nicotine" effect.1
