As for suppurations(40), which happen in any internal part, when they begin, our first business is to endeavour by repellent cataplasms to prevent a hurtful collection of matter; and then, if these have no effect, to disperse it by discutient malagmas. If we fail in that, it follows that it be encouraged; next, that it be maturated. And then the end of every vomica is, that it breaks; and the symptom of this is an evacuation of matter, either by the mouth or anus. But nothing ought to be done, by which a full discharge of the pus may be prevented. Gruels and warm water must be chiefly used. When the pus has ceased to be discharged, we are to change to such food, as is indeed of easy _concoction_, but yet more substantial and cold; also cold water, but beginning with taking the cold off both: and at first some things may be eaten with honey, as pine-nuts, or sweet almonds, or hazel-nuts. Afterwards even the honey must be omitted, that a cicatrix may be the sooner formed. At that time the proper medicine for the ulcer is taking the juice of leeks or horehound, and adding leeks to every meal. It will be convenient also to use frictions in those parts, that are not affected, and gentle walks. And care must be taken not to irritate the healing ulcers either by struggling or running, or any other means; for in this distemper, a vomiting of blood is destructive, and therefore by all means to be guarded against. A. CORNELIUS CELSUS OF MEDICINE. _BOOK IV._ CHAP. I. OF THE INTERNAL PARTS OF THE HUMAN BODY. Thus far we have spoken of those kinds of distempers, which so affect the whole body, that no certain seats can be assigned to them: I shall now treat of those which belong to particular parts. Now the diseases of all the internal parts, and their method of cure will be more easily understood, when I shall have first given a short description of the parts they afflict.
