Called also petroselinum vulg. apium selinum, common or garden parsley. Apium petroselinum or apium hortense Lin. Sp. Pi. 379. It is too well known to need description. The roots are diuretic, and are employed in a decoction, which should be drunk plentifully. Distilled with water, a small portion of essential oil is obtained; spiritus vini rect. extracts the whole of their virtues, and after evaporation, leaves a good extract. The leaves are warmer than the roots, and afford more essential oil; but the seeds are the best part of the plant: they are warm, carminative, bitter, and diuretic. Three pounds of the seeds yield about i. of essential oil, the most of which sinks in water. The roots are said to be aperient and diuretic, and have been employed in apozems to relieve nephritic pains and obstructions of urine. The bruised leaves have been successfully used as a discutient poultice to many tumours. Though commonly eat at table, it has been supposed in some constitutions to occasion epileptic fits, or at least aggravate them in those subject to this disease. The virtues of this plant, and the injuries supposed to result from it, are alike inconsiderable.

We have only the seeds in the shops, which differ from the common sort in being dark coloured, and covered with a rough hoariness: their virtues are similar to, but weaker than, the common sort.
