To drive Boils and Swellings away (Spell)

From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:

To drive Boils and Swellings away.

Go to a butcher, who is about slaughtering a cow, speak to him, but beseech him three times for the sake of God, give me the bladder containing the water. Let the water after this run out, so that the water of the sick man may run into the bladder; thereupon hang the bladder in the smoke with the water in it. It will surely help.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
