The seeds of these plants only are used in medicine. The common sort is a native in the southern parts of Europe; and the seeds of this species are larger,.paler, and very different in flavour, as well as in medical power, from the true, which is a native of Egypt; and the seeds are of a reddish brown colour, small, and flat on one side, convex and furrowed on the other. We very rarely meet with them; the seeds of the amomum, and of parsley, being often sold for them.

The seeds of the true bishop weed are an agreeable carminative, of a moderately warm taste, resembling origanum in their smell. By distillation with water, they yield much oil of a yellowish colour, and containing their whole flavour; spirit of wine also conveys their odour. These seeds have been recommended as emmenagogues and diuretics, but are only moderately warm stomachics. Ammion. See Cinnabars..
