For worms which form in ulcers, the first thing to be done is to stop the humidity and the putrefaction which occasion them. Worms may be killed by all the things in general which are described for those in the ear. But for those which form in ulcers Archigenes says, mix equal parts of ceruse and poley with liquid pitch, and anoint with it.
Commentary. Aëtius recommends dried plantain, the ashes of the wood of figs, and the juice of calamint. Galen and Avicenna also mention calamint.
Pliny mentions the gall of frogs.
SECT. XLIII.—ON FUNGOUS ULCERS.
The fungous flesh of ulcers is to be removed by medicines which are powerfully desiccant, such as diphryges sprinkled upon it, the squama æris, all the testacea burnt, both the echini (the hedgehog and sea-urchin,) burnt entire. But the following things are moderately cleansing, and repress the fungous flesh: the flower of the Asian stone, and still more powerful than it, the sori and chrysocolla, chalcitis and misy (when burnt they are less caustic,) and the flos æris in like manner; but verdigris is the most powerful of all. Salts, when burnt, consume the foul flesh, and in like manner charpie that has been soaked in strong brine and dried, consumes fungous flesh that is moderately large. But verdigris with the squama æris is powerfully repressing. Of the compound applications the powder called rhodium, and the psarum, and that named yellow, repress fungous growth without being pungent. But the trochisks called phaustiani, when levigated and sprinkled on the sore, and the dry medicine (or powder) called heliocaes, make fungous flesh slough off to the bottom. But the application consisting of equal parts of calx viva, squama æris and manna, answers with fungous flesh; with honey it cleanses such as resemble a mushroom, and with cerate it proves incarnating.
A powder for keeping down fungous flesh: Of litharge, of chalcitis, of verdigris, of plumbago, equal parts.—Another, which represses strongly without being pungent, and applies also to spreading ulcers, and more especially the epulis of the gums, and whitens the teeth: Of quicklime, lb. j; of arsenic, oz. vj; having triturated the dried arsenic with water, add the lime washed like calamine, and, having rubbed them together dry and use. And of the trochisks, that called pantolmios, and those described for polypus, are excellent for repressing fungus in ulcers. But the green plasters, more especially the one from Cappadocian salts, and in like manner the isis, are most effectual in preventing fungous flesh in ulcers.
Commentary. The powerful applications mentioned by our author will be found amply sufficient to fulfil every intention in conducting the treatment of these ulcers. Many of them are mentioned by Hippocrates.
Galen lays it down as a rule that these fungous excrescences are to be repressed by powerfully desiccative substances, such as misy, chalcitis, or more especially verdigris; when burnt and washed they become mild detergents. (Meth. Med. iii.)
Aëtius gives many useful prescriptions for such preparations, but they are entirely formed of the ingredients which enter into those of our author.
