From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
For the Purging of the Sheep.
Laurel oil and excecizium made into a salve, and the body greased with it; Spanish fly, five cents; laurel oil, five cents; evorbium, five cents; lard one quart, and three-points of a knife full of salt. All of these mix cold and grease several days in succession.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
