A good Ointment for Serious Warts (Spell)

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

A good Ointment for Serious Warts.

Make a white turnip hollow inside by taking the pit out, put fresh butter therein, also a fresh hen's egg. Let these articles be rendered by broiling inside, pour through a cloth. with a little rose water added, and boil it till it becomes the consistency of a salve. This is a very reliable ointment.
