Robert Fludd, M.D., the Rosicrucian, who fell under the displeasure of the College of Physicians on account of his unsound views from a Galenical standpoint, was a warm advocate of the Paracelsian Weapon Salve. In reply to a contemporary doctor who had ridiculed the theory he waxes earnest, and at times sarcastic. He explains that “an ointment composed of the moss of human bones, mummy (which is the human body combined with balm), human fat, and added to these the blood, which is the beginning and food of them all, must have a spiritual power, for with the blood the bright soul doth abide and operateth after a hidden manner. Then as there is a spiritual line protracted or extended in the Ayre between the wounded person and the Box of Ointment like the beam of the Sun from the Sun, so this animal beam is the faithful conductor of the Healing nature from the box of the balsam to the wounded body. And if it were not for that line which conveys the wholesome and salutiferous spirit, the value of the ointment would evaporate or sluce out this way or that way and so would bring no benefit to the wounded persons.” Van Helmont, Descartes, Batista Porta, and other leaders of science, in the seventeenth century, espoused the theory cordially enough. Van Helmont’s contribution to the evidence on which it was founded is hard to beat. In his “De Magnetica Vulnerum Curatione,” written about 1644, he relates that a citizen of Brussels having lost his nose in a combat in Italy, repaired to a surgeon of Bologna named Tagliacozzi, who provided him with another, taking the required strip of flesh from the arm of a servant. This answered admirably, and the Brussels man returned home. But thirteen months later he found his nose was getting cold; and then it began to putrefy. The explanation, of course, was that the servant from whom the flesh had been borrowed had died. Van Helmont adds, “Superstites sunt horum testes oculati Bruxellae”; there are still eye-witnesses of this case at Brussels. Moss from a dead man’s skull is a principal ingredient in all the sympathetic ointments, and the condition that the dead man should have died a violent death is generally insisted on. But Van Helmont, quoting from one Goclenius, adds another condition still more absurd. It is that the dead man’s name should only have three letters. Thus, for example, Dod would do, but not Dodd.
