PILEWORT, (Ranunculus ficaria, Lin.), the root. This is a very small plant, found in moist meadows and by hedge sides. The roots consist of slender fibres with some little tubercles among them, which are supposed to resemble the hæmorrhoids. From thence it has been concluded, that this root must needs be of wonderful efficacy for the cure of that distemper: to the taste, it is little other than mucilaginous; and although still retained in several of the foreign pharmacopœias, it is hardly in use in this country.
