From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
When a Person is Prevented from Passing Water.
Take a good handful of hare's hair, burn it till it becomes powder, wrap it in a handkerchief, add three handfuls of watercresses and a half a quart of wine, boil the powder and herbs therein. Drink it warm.
The grimoire Egyptian Secrets of Albertus Magnus lists this spell.
