Cardamomum Majus seu grana pa-radifi Pharm. Paris. Meleguetta & maniguetta & cardamomum piperatum quibusdam. Amo-mum Grana Paradisi. Linn, Grains of paradise, called by some greater cardamoms: angular reddish brown seeds, smaller than pepper, in appearance much resembling cardamom seeds, brought from the East Indies. The grains of paradise and cardamom plants belong both to one botanic genus, the amomum of Linnaeus.
In pharmaceutical properties, the grains of paradise differ greatly from cardamom seeds, and greatly resemble pepper. They have fome-what of the flavour of the former, joined to the heat and pungency of the latter; which pungency resides, not like that of cardamoms in the volatile parts or essential oil, but like that of pepper in the resinous or more fixt matter. The distilled oil of grains of paradise, in smell sussiciently agreeable, is in taste of the milder kind: the remaining decoction, infpifTated, yields an extract of considerable pungency: an extract made by rectified spirit is highly fiery. This spice is employed in some places for the same purposes as pepper; among us it is rarely directed for medicinal purposes.
