CHAP. L. To make a Potion of Camedrios, and Iva Artetica, which dis∣solveth all Fevers that come with cold.

THe Herb Iva Artetica, as I have shewed in another place, is of marvellous vertue, also the Camedrios is of great ver∣tue, and is hot and dry by nature. The Iva is good against the accident of the Fever, and the Camedrios dissolveth the melancholie humour; and therefore when a decoction is made of these two Herbs, it will work a marvellous effect in the cure of the said Fever, because it provoketh sweat, and assubtiliateth the grossenesse of the humour, and ex••in∣guisheth the accident of the Fever in such sort, that the Fever shall resolve with good successe, and the order to make that Potion is thus.

Take Camedrios, and Iva Artetica, of each one pound, and dry them in the shadow, Lignum Aloes ℥. i. the seed of Wal∣wort

℥. iiii. common Honey ℥. vi. fine Sugar one pound, strong white wine xvii. pound: Mix all these together in a distilling glasse, and so let it stand three daies, then distill forth three pound, and let it cool, and strain it through a Searce, and put thereunto the water that ye distilled out be∣fore, then passe it by a filter three or four times untill it bee clear, then keep it in a Glasse close shut that it take no aire, and it will last a long time without corruption, and when any will take it against the said Fever coming with cold, give him every morning fasting ℥. v. warm, and let him lie down to sweat as much as he may, and fast thereron at the least four hours, and take heed yee eat no things that are cold, and moist, for they will hinder the cure very much, and at night when he goeth to bed, give him ℥.iii. warm, and if it hap that in his sleep he sweat, dry him well with warm clothes, and thus doing, in short time he shall be delivered of that infirmitie, for this I have used divers and sundry times to my great honour, and profit of the Patient.
