From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
How to Heal Raw Flesh Spots within twenty-four hours.
In the first place, split and cut the four streaks on their feet, in the middle. Then take three ounces of powdered bay leaves, the whites of twenty eggs, two ounces of teriac, two quarts of strong wine, and boil all together to one-half of its original volume. Let the horse drink this as warm as he can bear it. Then soak a woolen blanket in cold water, cover the horse with it, and put the belly-band on, that the blanket will not fall off, and let it remain for twenty-four hours. Give it neither food nor drink during this time. After this you may ride him again, and feed carefully. This is a well approved art.
