When a Splinter or Thorn is Sticking in the Leg (Spell)

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

When a Splinter or Thorn is Sticking in the Leg.

Take a white garlic onion, cut it fine, take the same weight of pitch, render the pitch down and dissolve the onion therein until it becomes the thickness of a plaster, which must be put upon the sore spot, which will soon heal, and the thorn may be easily removed.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
