From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
A good Black Plaster.
Take one-half pound of olive oil, a quarter of a pound of silver litherage, a quart of good vinegar; rose vinegar would be the best for the purpose. Stir all these articles together in a pan placed upon the fire till the mass becomes black. Then pour it into pure water, and grind it upon a stone or board together. It is a good remedy for all sorts of injuries.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
