It is necessary also to consider, whether fevers are simple, or whether other disorders are not likewise concomitant; that is, whether the head be pained, the tongue rough, or the præcordia tense. If there be pains in the head, it is proper to mix oil of roses with vinegar, and to apply that(10); then to have two pieces of cloth, which are as broad and as long as the forehead; to have one of these alternately in the vinegar and rose-oil, and the other on the forehead; or to put on sordid wool dipped in the same. If vinegar is offensive, pure oil of roses must be used. If even the rose-oil is offensive, bitter oil. If these do little service, dry iris, or bitter almonds, or any of the cooling herbs may be powdered. Any of them mixed with vinegar and laid upon the part lessens the pain: but in some one of these is more successful, and in others another. Relief is also procured by bread laid on with poppies, or with oil of roses, cerus, or litharge. It is also not improper to smell at either serpyllum or dill. But if there is an inflammation and pain in the præcordia, in the first place restringent cataplasms must be applied; and not the hotter kind, lest there should be a greater flux of matter thither. After that, as soon as the inflammation has abated, recourse must be had to hot and moist, in order to discuss what remains. Now the marks of inflammation are four, redness, and swelling, together with heat, and pain. So much was Erasistratus mistaken, when he declared there was no fever without it. Wherefore if there is pain without inflammation, nothing is to be applied at all; for the fever itself will presently remove that. But if there is neither an inflammation, nor fever, but only a pain of the præcordia, warm and dry fomentations may be immediately used. If the tongue is dry and scabrous, it is first to be wiped with a penecillum dipped in hot water; and then anointed with a mixture of rose-oil and honey. The honey cleanses, and the oil of roses restringes, and at the same time does not suffer it to grow dry. But if it is not rough, but only dry, after wiping it with the penecillum it ought to be anointed with rose-oil mixed with a little wax. CHAP. XI.
