From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
When Cattle have Soft Feet.
Take five cents' worth of aquafortis, fifteen cents' worth of brandy, three or four eggs, and put all into a dish, and let it remain a while. It will cook itself. With this grease the hoofs every day two or three times.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
