CHAP. XXIX. Of Ʋlcers in the mouth, their Kinds and Remedies.

ULcers that come in the mouth are of divers and sundry kinds, for some proceed of heat in the head, others of cold, others are humours Gallico. Those that come of heat in the head, are as it were scorched with great burn∣ing within them, and the cure thereof is in letting blood in the veins under the tongue, and the next day give him one dose of our Electuario angelica, and let him wash his mouth with Planten water, wherein is boiled Tutia prepared, Roch Allum, and Honie of Roses, and this is the true order to cure those kind of Ulcers with speed. Those Ulcers which are cau∣sed of cold, are a certain hardnesse alterated, which cause little pain; and the cure of these is to drinke our Vegitabi∣le Quinta essentia, with Mel Rosarum: and dresse the Ulcer with Oil of Sulphur and Tartur mixed: And herein consist∣eth a great Secret worthy to be known, and is of our inven∣tion. Ulcers that are caused of Morbo Gallico, if you will cure them, you must first remove the cause, as I have said di∣vers times, and touch them with our Castick. and let the Pati∣ent hold his mouth open a good while after, that the Water may run out: And then make a Lavatory of Aqua vitae, Honey, and Oil of Vitriol, aad therewith wash the mouth, for these are great Secrets which bring both health to the Patient, and honour to the Professor of this Art.
