From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
Another Remedy for the Same Disease.
Take fresh turnips, grind them on the grater, press the juice out, and with it rinse the mouth frequently. In lieu of fresh turnips, dried ones will answer the same purpose. A handful of these boil in a quart of water, wherewith rinse and gargle the mouth and throat frequently. It does not matter if the patient should swallow some of this, it allays the heat.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
