An especially approved Powder for the Gravel (Spell)

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

An especially approved Powder for the Gravel.

Burn the blood of a hare and the entire skin in a new earthen pot to ashes, and give it to the patient dissolved in warm water. Let him take a spoonful before breakfast. It is aston­ishing what a powerful effect this powder exercises.

The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
