The doctrine of contraries drawn from the old Greek philosophy, upon which a good deal of the treatment of Hippocrates and Galen was based--dryness expelled by moisture, cold by heat, etc.--was opposed by Paracelsus in favor of a theory of similars, upon which the practice of homeopathy is based. This really arose from the primitive beliefs, to which I have already referred as leading to the use of eyebright in diseases of the eye, and cyclamen in diseases of the ear because of its resemblance to that part; and the Egyptian organotherapy had the same basis,--spleen would cure spleen, heart, heart, etc. In the sixteenth and seventeenth centuries these doctrines of sympathies and antipathies were much in vogue. A Scotchman, Sylvester Rattray, edited in the "Theatrum Sympatheticum"[15] all the writings upon the sympathies and antipathies of man with animal, vegetable and mineral substances, and the whole art of physics was based on this principle.

Upon this theory of "mumia," or magnetic force, the sympathetic cure of disease was based. The weapon salve, the sympathetic ointment, and the famous powder of sympathy were the instruments through which it acted. The magnetic cure of wounds became the vogue. Van Helmont adopted these views in his famous treatise "De Magnetica Vulnerum Curatione,"[16] in which he asserted that cures were wrought through magnetic influence. How close they came to modern views of wound infection may be judged from the following: "Upon the solution of Unity in any part the ambient air . . . repleted with various evaporations or aporrhoeas of mixt bodies, especially such as are then suffering the act of putrefaction, violently invadeth the part and thereupon impresseth an exotic miasm or noxious diathesis, which disposeth the blood successively arriving at the wound, to putrefaction, by the intervention of fermentation." With his magnetic sympathy, Van Helmont expressed clearly the doctrine of immunity and the cure of disease by immune sera: "For he who has once recovered from that disease hath not only obtained a pure balsaamical blood, whereby for the future he is rendered free from any recidivation of the same evil, but also infallibly cures the same affection in his neighbour . . . and by the mysterious power of Magnetism transplants that balsaam and conserving quality into the blood of another." He was rash enough to go further and say that the cures effected by the relics of the saints were also due to the same cause--a statement which led to a great discussion with the theologians and to Van Helmont's arrest for heresy, and small wonder, when he makes such bold statements as "Let the Divine enquire only concerning God, the Naturalist concerning Nature," and "God in the production of miracles does for the most part walk hand in hand with Nature."
[16] An English translation by Walter Charleton appeared in 1650, entitled "A Ternary of Paradoxes."
That wandering genius, Sir Kenelm Digby, did much to popularize this method of treatment by his lecture on the "Powder of Sympathy."[17] His powder was composed of copperas alone or mixed with gum tragacanth. He regarded the cure as effected through the subtle influence of the sympathetic spirits or, as Highmore says, by "atomicall energy wrought at a distance," and the remedy could be applied to the wound itself, or to a cloth soaked in the blood or secretions, or to the weapon that caused the wound. One factor leading to success may have been that in the directions which Digby gave for treating the wound (in the celebrated case of James Howell, for instance), it was to be let alone and kept clean. The practice is alluded to very frequently by the poets.
In the "Lay of the Last Minstrel" we find the following:
[17 French edition, 1668, English translation, same year. For a discussion on the author of the weapon salve see Van Helmont, who gives the various formulas. Highmore (1651) says the "powder is a Zaphyrian salt calcined by a celestial fire operating in Leo and Cancer into a Lunar complexion."
But she has ta'en the broken lance, And wash'd it from the clotted gore, And salved the splinter o'er and o'er.
William of Deloraine, in trance, Whene'er she turn'd it round and round, Twisted, as if she gall'd his wound, Then to her maidens she did say, That he should be whole man and sound, (Canto iii, xxiii.) and in Dryden's "Tempest" (V, 1) Ariel says:
Anoint the Sword which pierc'd him with the Weapon-Salve, And wrap it close from Air till I have time To visit him again.
From Van Helmont comes the famous story of the new nose that dropped off in sympathy with the dead arm from which it was taken, and the source of the famous lines of Hudibras. As I have not seen the original story quoted of late years it may be worth while to give it: "A certain inhabitant of Bruxels, in a combat had his nose mowed off, addressed himself to Tagliacozzus, a famous Chirurgein, living at Bononia, that he might procure a new one; and when he feared the incision of his own arm, he hired a Porter to admit it, out of whose arm, having first given the reward agreed upon, at length he dig'd a new nose. About thirteen moneths after his return to his own Countrey, on a sudden the ingrafted nose grew cold, putrified, and within few days drops off. To those of his friends that were curious in the exploration of the cause of this unexpected misfortune, it was discovered, that the Porter expired, neer about the same punctilio of time, wherein the nose grew frigid and cadaverous. There are at Bruxels yet surviving,some of good repute, that were eye-witnesses of these occurrences."[18]
