gnawes and feeds upon the parts which lye under, and are adjoyning to the Vlcer, and makes an eating Vlcer. Such Vlcers are by Galen called Dysepulotica, that is, difficultly to be cicatrized; for, saith he, it happens that the Vlcer is Dysepuloticke, either for that the part affected may be vitiated either in the habit or temper there∣of, so that it may corrupt the humor which flowes thither; such an Vlcer is by a particular name tearmed Cacoethes; or for that by reason of the evill quality of the blood flowing thither and eating the part, the part affected being too moist cannot heale up. He further addes that a Chironian Vlcer is farre more maligne than these Vlcers which are tearmed Cacoethe.
For the cure; by reason that all these Vlcers have a large extent, for some are more maligne and ill to be cicatrized than othersome; it is also necessary to have divers medicines ready and at hand distinct both in their faculties and the degrees thereof; so that it is no marvaile if they oft faile of their purpose, who with the same medicine dresse and thinke they shall heale all maligne Vlcers. This following me∣dicine described by Asclepiades is much commended by Galen.
℞. squamae aeris, aeruginis rasae, an. ℥j. cera lb. ss. resinae laricis. ℥jss. quae liquari possunt aridis affundantur, and make an emplaister to bee laid onely upon the Vlcer; for you must lay a defensative about the Vlcer for feare of inflammation. But Galen saith, that the following Epuloticke of Primion excells the rest, as that which to despe∣rate Vlcers, (which many have taken in hand and left as uncurable,) was of certaine and approoved use.
℞ soreos ℥iij aluminis scissilis, calcis viuae, an ℥ij. thuris, gallarum, an. ℥iiij. cerae, lb. j & ℥iij. sevi vitulini lb. j. & ℥vij. olei veteris quantum sufficit, fiat emplastrum.
