From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
How to make a good Stomach Plaster.
Take two ounces of melted wax, in which stir a drachm of each of the following: ground cloves, nutmeg, alba cevatria and turpentine.
After straining all these articles through a cloth, add ten grains of wormwood oil, stir all well together till it becomes cold, spread it upon a piece of muslin; when cold, paint balsam of cloves over it, wherewith it may be freshened up from time to time. Apply to the stomach externally. It is a very efficacious remedy.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
