SECT. L.—FOR SORES WHICH BREAK OUT AGAIN.
Some sores which have become cicatrized, often after no long time become inflamed and break out again; for a bone being diseased, sometimes the flesh which covers it heals up readily and appears sound, but in a short time a strong defluxion taking place from the corrupted bone below, inflammation supervenes, and pus is formed which corrodes the cicatrix. What then is the cure of such ulcers? Dry the diseased bone to such a degree that it may exfoliate. But the diseased part of the bone may easily be brought up if you apply a cataplasm, consisting of fig leaves triturated with fine dried barley flour and wine. Or you may apply equal parts of the reed of henbane and of copperas triturated together. The root of hog’s-fennel speedily removes the laminæ of bones.
Commentary. This chapter is copied from Aëtius, who gives some additional prescriptions, such as one consisting of the scales of copper, frankincense, alum, sal ammoniac, pomegranate rind, and ceruse, with or without cerate; and another consisting of red arsenic finely triturated with bear’s fat.
Avicenna recommends strong attractive applications, such as a plaster of the leaves of the black poppy with fig leaves; and another containing the atramentum sutorium (sulphate of copper.)
