The sympathetic egg was another device to cheat diseases, attributed to the same inventive genius. An empty chicken's egg was to be filled with warm blood from a healthy person, carefully sealed and placed under a brooding hen for a week or two, so that its vitality should not be impaired. It was then heated in an oven for some hours at a temperature sufficient to bake bread. To cure a case this egg was placed in contact with the affected part and then buried. It was assumed that it would inevitably take the disease with it, as healthy and concentrated blood must have a stronger affinity for disease than a weaker sort.
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."
