From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
How to Heal the Broken Legs of Sheep or other Animals.
Fractured leg, I bless thee this very day, as now the dear Lord, the Father, as now the dear Lord the Son, as now the dear Lord the Holy Spirit will order it. Wholesome he this hour, when our beloved Lord Jesus Christ was born. Now I take this hour, and over this wound I cover, that this broken leg may not swell nor fester till the mother of God, shall have another son. + + +
For such a broken leg, the following plaster must be used: Some good gunpowder, made fine, leaven, half the size of an egg, and the whites of two eggs. Stir and beat together, and apply over the wound. It is approved.
