shall use the like discretion in taking off these, as you use in your unctions and fricti∣on. Instead of Emp. de Vigo, this following may be fitly used. ℞. massae emp. de melil. & oxycrocei, an. lb ss. argenti vivi extin. ℥vi. ol••o laurino, & de spica, reducantur ad for∣mam emplastri. These plasters must be equally spread upon leather, and layd upon the same places of the joints, as were formerly mentioned in the cure by frictions. Yet some there bee, who cover with the plaster all the arme, from the hand e∣ven to the shoulder, and all the legge, from the toppe of the knee, even to the ends of the toes, which thing I doe not disallow of, if so bee that the places of the joints bee covered over with a thicker plaster. They must bee left sticking there so long, untill nature be stirred up and provoked to cause excretion of the virulent hu∣mours. Yet if in the interim great itching shall arise in the parts, you may take them off so long untill the parts shall be fomented with a decoction of the flowres of cha∣momile, melilote, red roses, and the like, made in wine, to discusse that which cau∣sed the itching, and then you may lay them on againe. Some, to hinder the rising of any itch, lay not the bare plaster to the part, but cover it over with sarcene••, so to keepe it from sticking, and thus intercept the transpiration of the part, the cause of itching. They shall bee stronger or weaker, and lye to the part a longer or shorter space, as long as the indications, so often formerly mentioned, shall seem to require. The effects of emplasters are the same as of frictions, for they cause excretion, one while by insensible transpiration, otherwhiles by a Diarrhae••, or fluxe of the belly, sometimes by urines, but most frequently (which Crisis is also most certaine) by sa∣livation. Sordide and virulent ulcers often breed in the mouth, tongue, pallate, and gummes by salivation, by reason of the acrimony of the virulent humors adhering to the sides of the mouth: to hinder the growth of these, many inject glysters made of e∣mollient things, especially at the beginning of the salivation, so to draw downwards the humours forcibly flying up in greater quantity than is fit, although the part it selfe may endure them.
There are also some, who to the same end give a purging medicine at the very time when as the humours are ready to move upwards, the which I thinke is not a safe course. The cure of such ulcers is farre different from the cure of others. For they ought by no meanes to bee repercussed or repelled, how enflamed soever they be, but onely to bee mitigated by anodyne gargarismes, so onely to lessen the heat, and that by this frequent washing of the mouth, you may hinder the sticking or fur∣ring of viscide humours to such like ulcers. A decoction of barly, cowes milk warm, held and gargled in the mouth, the mucilages of the seeds of mallowes, marsh-mal∣loxes, psilium, lettuce, line extracted in the water of barly, mallowes, and pellitory of the wall, are good for this purpose; for thus the ulcers become more milde, and the tenacity of the adherent humours is loosed. You must at the first beware of strong detergent medicines, for almost all such have acrimony joyned with them, which will encrease the pain, but chiefly in the state of the disease: for so, the ulcers gently cleansed by frequent gargling, would become worse by the use of acride things. Therefore it shall be sufficient to make use of the forementioned medicines, so to hinder the encrease of the filth, and inflammation of the ulcers, if so bee that such ulcers be not too exceeding maligne and burning. For if it shall happen either by the powerfull efficacy of the applyed plasters, or by the violence of nature in its motion of the ill humours upwards, that such store of viscous, and grosse humours are carryed to the mouth, that it wants little, but that the part it selfe is over-ruled by the morbificke matter, so that by the violence and continuance of the fluxe, the mouth and jawes become so swelled, that a gangrene is to be feared, by hindering the entrance of the spirits, and extinguishing of the native heat of these parts. In this case wee are forced to leave the proper cure for to withstand the accidents, and for this purpose we use restrictive & repelling things, such as are barly water, plantain, night-shade, knot-grasse, shepheards Purse, &c. with syrupe of roses, violets, quin∣ces, berberies, pomegranates, &c. also such are the mucilages and decoctions of the seeds of lettuce, psilium, quinces, plantaine, cucumbers, melons, white poppy, hen-bane, in the waters of roses, plantaine, night-shade, water-lillies, wood bin••, &c. Also it is convenient to procure sweats by stoves, or the application of any hot and
