As the Arabians give the same account of the origin and symptoms of quotidians, we need not enter upon a detail of their descriptions. All agree that they are connected with phlegm as an exciting cause, and that the fever is less ardent and well-marked than in the case of tertians. SECT. XXV.—THE CURE OF QUOTIDIANS. In curing the quotidian, we use oxymel during the first days, and those things which properly promote the discharge of urine. And, upon the whole, the diet ought to be incisive; but, at its acme, we must look to the stomach, particularly its orifice. We must also prescribe an emetic from radishes taken with food, and phlegmagogue cathartics in abundance, until it subside. * * * * * COMMENTARY. This Section is taken from Oribasius (Synops. vi, 14.) Celsus enjoins abstinence for three days; after which food is to be taken every alternate day. After the fever has subsided, he recommends the bath and wine. Galen’s treatment is exactly the same as our author’s. Alexander, as usual, makes nice distinctions as to the circumstances under which each of the remedies ought to be applied. In general, he approves of incisive and attenuant medicines, but blames Galen for recommending the latter too indiscriminately. He forbids cataplasms and embrocations at the commencement, lest they should occasion a determination of the humours to the affected part. Synesius appears to have proceeded upon much the same principles as our author, but he makes mention of some additional medicines, such as camphor, wormwood, and the like. Nonnus recommends, at first, things of an incisive and attenuant nature, and then emetics, after which the phlegm is to be purged by means of colocynth and agaric, and cataplasms and fomentations are to be applied to the pit of the stomach. Avicenna lays down the rules of treatment with so great minuteness, that we cannot venture upon an abridgment of them. His principles, however, seem to be the same as those of Galen. Averrhoes recommends, for the first seven days, medicines of an incisive, attenuant, and deobstruent nature. He then gives cathartics which evacuate phlegm, such as turbith, agaric, and hiera picra, but forbids the use of colocynth. He approves very much of friction, the mode of applying which is minutely described by him. Rhases recommends much the same treatment. He, in particular, recommends turbith and agaric along with wormwood and mastich. Haly’s remedies are mostly diluents and attenuants. Alsaharavius recommends the same remedies as Rhases. SECT.
