CHAP. 56.—SILAUS: ONE REMEDY.
Silaus[1275] is a plant which grows in running streams with a gravelly bed. It bears some resemblance to parsley, and is a cubit in height. It is cooked in the same manner as the acid vegetables,[1276] and is of great utility for affections of the bladder. In cases where that organ is affected with eruptions,[1277] it is used in combination with root of panaces,[1278] a plant which is otherwise bad for the bladder. The erratic apple,[1279] too, is an expellent of calculi. For this purpose, a pound of the root is boiled down to one half in a congius of wine, and one hemina of the decoction is taken for three consecutive days, the remainder being taken in wine with sium.[1280] Sea-nettle[1281] is employed too for the same purpose, daucus,[1282] and seed of plantago in wine.
