From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
An Ointment for various kinds of Pimples and Boils, also for Small-Pox, etc.
Take some unwatered butter, raw bees'-wax, pitch, saffron, for five cents, some sulphur; the sulphur must be melted in a pan, afterward add the wax, pitch, saffron, and last the butter, let it boil well together, as long as a soft egg, or till it foams over. Put it upon a rag and tie as warm as it can be borne upon the pimples and kept tight by means of another band. This is an excellent thing for poisonous eruptions of all kinds. Probatum.
