CHAP. 27.—HIERACIUM.
“Hieracium”1623 is the name given to an eye-salve, which is essentially composed of the following ingredients; four ounces of sal ammoniac, two of Cyprian verdigris, the same quantity of the kind of copperas which is called “chalcanthum,”1624 one ounce of misy1625 and six of saffron; all these substances being pounded together with Thasian vinegar and made up into pills. It is an excellent remedy for incipient glaucoma and cataract, as also for films upon the eyes, eruptions, albugo, and diseases of the eye-lids. Verdigris, in a crude state, is also used as an ingredient in plasters for wounds. In combination with oil, it is wonderfully efficacious for ulcerations of the mouth and gums, and for sore lips. Used in the form of a cerate, it acts detergently upon ulcers, and promotes their cicatrization. Verdigris also consumes the callosities of fistulas and excrescences about the anus, either used by itself, applied with sal ammoniac, or inserted in the fistula in the form of a salve. The same substance, kneaded with one third part of resin of turpentine, removes leprosy.
