Extraordinary Popular Delusions & the Madness of Crowds (pg 321):
As this new doctrine of magnetism spread, it was found that wounds inflicted with any metallic substance could be cured by the magnet. In process of time, the delusion so increased, that it was deemed sufficient to magnetise a sword, to cure any hurt which that sword might have inflicted! This was the origin of the celebrated "weapon-salve,' which excited so much attention about the middle of the seventeenth century. The following was the reipe given by Paracelsus for the cure of any wounds inflicted by a sharp weapon, except such as had penetrated the heart, the brain, or the arteries. "Take of moss growing on the head of a thief who has been hanged and left in the air; of real mummy; of human blood; still warm--of each, one ounce; of human suet, two ounces; of linseed oil, turpentine, and Armenian bole--of each, two drachms. Mix all well in a mortar, and keep the salve in an oblong, narrow urn." With this salve the weapon, after being dipped in the blood from the wound, was to be carefully anointed, and then laid by in a cool place. In the mean time, the wound was to be duly washed with fair clean water, covered with a clean, soft, linen rag, and opened once a day to cleanse of purulent or other matter. Of the success of this treatment, says the writer of the able article on Animal Magnetism, in the twelfth volume of the
Foreign Quarterly Review, there cannot be the least doubt; "for surgeons at this moment follow exactly the same method,
except anointing the weapon!"
