From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
Another Remedy for the Above. (To Restore Manhood.)
Take a new fresh laid egg, if possible, one that is yet warm. Pour whale oil over it, and boil the egg in it; the oil then should be poured into a running water, stream downward, never upward, then open the egg a little, carry it to an ant's hill, of the large red specie, as are found in fir-trees forest, and there bury the egg. As soon as the ants have devoured the egg, the weak and troubled person will be restored to former strength and vigor.
