Peucedanum palustre Mnch. Marsh Parsley. Marsh Smallage. Persil de Marais, Fr. Radix Olsnitii. Sumpfsilge, Elsenich, G.—The root of this European umbellifer is, when dried, of a brown color externally, having a strong aromatic odor, and an acrid, pungent, aromatic taste. Peschier found it to contain a volatile oil, a fixed oil, and a peculiar acid which he calls selinic. It has been used for epilepsy in Russia. Dose, from twenty to thirty grains (1.3-2.0 Gm.) thrice daily, rapidly increased to four times the amount. (J. P. C., 1859.)
