CHAP. XXV. A great Secret that helpeth the continuall Fever.

THese Fevers that are not accidentall, that is, not caused of a wound or imposthume, or other kind of infirmitie appa∣rent, are caused of a certaine humour between the skin and the flesh, which would have exhalation: as you may see by ex∣perience in this kind of Fever, how that sweats and boxing is very appropriate to their solution. And in this case I will shew thee a great remedie, with which after convenient purg∣ing thou mayest helpe in manner all those kindes of Fevers. And this is the remedie: Take Oippa ofir, the which is a simple well known to all the world, take of that hearb a small quanti∣ty, and stampe it a little, and lay it upon the wrist, and bind it hard, and there let it lye untill it have made a blister full of water, which you shall break, and there will come forth great abundance of water, and by that place the Fever shall be dis∣solved. And the reason is, because it evacuateth that humour which engendereth the accident: then the cause being remo∣ved, the effect will cease, and the Patient shall be whole.
