CHAP. XXVII. To make a divine and blessed Cerot against divers infirmi∣ties.

ULcers are of divers sorts, and are caused of sundry causes, as of Choller, Bloud, Flegme, Melancholy, and for that cause the Medicines would be agreeable; neverthelesse, I will shew thee a Cerot of such a temperature, that it will serve to help any sore in any place of the body, of what quality soever it be, except it be Scirro, or Noli me tangere, the which are in a manner counted uncurable, of the common Practitioners: but not by me, for I have cured them, and the order to make it is thus.

Take oil of Frankincense one pound, oil of Sulphur ℥. i. Vitrioll rubified ℥. iii. Precipate ℥. i. fresh Butter ℥. iii. and as much Wax as will suffice to make it in form of a Cerot, the which will have all the aforesaid intentions: because the Precipitate doth mundifie the Ulcer; the oil of Frankincense taketh away the pain, and incarnateth; the oil of Sulphur cleanseth; the Vitrioll drieth; the Butter mundifieth; and the Wax consolidateth, in such sort, that any one may perceive his vertue.
