- n. An acrid poisonous principle procured from Lobelia inflata, said to resemble nicotine.
In certain cases (lobeline, nicotine, cyanide, sulphide, etc.) the drug acts on the glomus, in others (e.g. Cardiazol) it acts by central stimulation and again in other cases (e.g. Coramine) it acts centrally and peripherally.
It may be mentioned here that the effects of the venomous alkaloid spigeline present in pinkroot is similar to those of nicotine, coniine and lobeline.
