CHAP. X. Of a virulent, eating and malign Ulcer, which is tearmed Cacoethes, and of a Chironian Ulcer.
VIrulent and eating Ulcers differ not, unless in magis and minus, for we tearm it a virulent Ulcer, which sends forth a virulent sanies, which is properly called Virus. This Virus, or virulency, when it becomes more malign, gnawes and feeds upon the parts which lie under, and are adjoyning to the Ulcer, and makes an eating Ulcer. Such Ulcers are by Galen cal∣led Dysepulotica, that is, difficultly to be cicatrized; for, saith he, it happens that the Ulcer is Dysepulotick, either for that the part affected may be vitiated, either in the habit or temper thereof, so that it may corrupt the humor which flowes thither; such an Ulcer is by a particular name tearmed Cacoethes; or for that by reason of the evil quality of the blood flowing thither and eating the part, the part affected being too moist cannot heal up. He further adds, that a Chi∣ronian Ulcer is far more malign than these Ulcers, which are termed Cacoethe. For the cure; by reason that all these Ulcers have a large extent, for some are more malign and ill to be cicatrized than other some, it is also necessary to have divers medicins ready and at hand, distinct both in their faculties and the degrees thereof, so that it is no marvail if they oft fail of their purpose, who with the same medicin dress (and think they shall heal) all malign Ulcers. This following medicin described by Asolepiades, is much commended by Galen. ℞. squammae aeris, aeruginis, rasae, an. ℥j. cerae lb. ss. resinae laricis ℥ j ss. quae liquari possunt aridis affundantur, and make an emplaster to be laid only upon the Ulcer; for you must lay a defensative about the Ulcer, for fear of inflamma∣tion. But Galen saith, that the following Epulotick of Primion excells the rest, as that which to desperate Ulcers (which many have taken in hand and left as uncurable,) was of certain and ap∣proved use. ℞. soreos ℥iij. aluminis scissilis; calcis vinae, an. ℥ij. thuris gallarum, an. ℥ iiij. cerae. lb. j. & ℥iij. sevi vitulini lb. j. & ℥vij. olei veteris quantum sufficit, fiat emplastrum.
