From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
Another Remedy for the above Disease.
Take a potful of pigeon manure, and boil it well. Then add some vinegar. Apply as a warm poultice, mornings and evenings. After removing the poultice, put the matter again into the pot, stir it, and use as before. Such a potful of manure may be used for eight days, but after that time a fresh potful has to be procured. This is a well approved art.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
