Celandine, and Horned or Prickly Poppy; a genus of the monogynia order, belonging to the polyandria class of plants. There are six species, none of which are remarkable for their beauty; but one of them, viz. the majus, is an article in the materia medica. It grows on old walls, among rubbish, and in waste shady places. The herb is of a bluish green colour; the root of a deep red; and both contain a gold-coloured juice: their smell is disagreeable, the taste somewhat bitterish, very acrid, burning and biting the mouth; the root is the most acrid. The juice takes off warts; cures scrofula, ring-worms, and the itch; and, diluted with milk, it confuses opake white spots on the eye.—Horses, cows, goats, and swine, refuse to eat the herb.
