THE POWDER OF SYMPATHY: A CURIOUS MEDICAL SUPERSTITIONOUT of the superstitions of the past the science of the present has gradually evolved. In the Middle Ages, what by courtesy we may term medical science was, as we have seen, little better than a heterogeneous collection of superstitions, and although various reforms were instituted with the passing of time, superstition still continued for long to play a prominent part in medical practice.
One of the most curious of these old medical (or perhaps I should say surgical) superstitions was that relating to the Powder of Sympathy, a remedy (?) chiefly remembered in connection with the name of Sir KENELM DIGBY(1603-1665), though he was probably not the first to employ it.
The Powder itself, which was used as a cure for wounds, was, in fact, nothing else than common vitriol,[1] though an improved and more elegant form (if one may so describe it) was composed of vitriol desiccated by the sun's rays, mixed with _gum tragacanth_.
It was in the application of the Powder that the remedy was peculiar.
It was not, as one might expect, applied to the wound itself, but any article that might have blood from the wound upon it was either sprinkled with the Powder or else placed in a basin of water in which the Powder had been dissolved, and maintained at a temperate heat.
Meanwhile, the wound was kept clean and cool.
[1] Green vitriol, ferrous sulphate heptahydrate, a compound of iron, sulphur, and oxygen, crystallised with seven molecules of water, represented by the formula FeSO47H2O. On exposure to the air it loses water, and is gradually converted into basic ferric sulphate.
For long, green vitriol was confused with blue vitriol, which generally occurs as an impurity in crude green vitriol.
Blue vitriol is copper sulphate pentahydrate, CuSO45H2O.
Sir KENELM DIGBY appears to have delivered a discourse dealing with the famous Powder before a learned assembly at Montpellier in France;at least a work purporting to be a translation of such a discourse was published in 1658,[1] and further editions appeared in 1660 and 1664.
KENELM was a son of the Sir EVERARD DIGBY (1578-1606) who was executed for his share in the Gunpowder Plot. In spite of this fact, however, JAMES I. appears to have regarded him with favour. He was a man of romantic temperament, possessed of charming manners, considerable learning, and even greater credulity. His contemporaries seem to have differed in their opinions concerning him. EVELYN (1620-1706), the diarist, after inspecting his chemical laboratory, rather harshly speaks of him as "an errant mountebank". Elsewhere he well refers to him as "a teller of strange things"--this was on the occasion of DIGBY'S relating a story of a lady who had such an aversion to roses that one laid on her cheek produced a blister!

(1658). This is entitled the second edition, but appears to have been the first.
To return to the _Late Discourse_: after some preliminary remarks, Sir KENELM records a cure which he claims to have effected by means of the Powder. It appears that JAMES HOWELL (1594-1666, afterwards historiographer royal to CHARLES II.), had, in the attempt to separate two friends engaged in a duel, received two serious wounds in the hand.
To proceed in the writer's own words:--"It was my chance to be lodged hard by him; and four or five days after, as I was making myself ready, he [Mr Howell] came to my House, and prayed me to view his wounds;for I understand, said he, that you have extraordinary remedies upon such occasions, and my Surgeons apprehend some fear, that it may grow to a Gangrene, and so the hand must be cut off....
"I asked him then for any thing that had the blood upon it, so he presently sent for his Garter, wherewith his hand was first bound: and having called for a Bason of water, as if I would wash my hands; I took an handful! of Powder of Vitrol, which I had in my study, and presently dissolved it.
As soon as the bloody garter was brought me, I put it within the Bason, observing in the interim what Mr _Howel_ did, who stood talking with a Gentleman in the corner of my Chamber, not regarding at all what I was doing: but he started suddenly, as if he had found some strange alteration in himself; I asked him what he ailed? I know not what ailes me, but I find that Ifeel no more pain, methinks that a pleasing kind of freshnesse, as it were a wet cold Napkin did spread over my hand, which hath taken away the inflammation that tormented me before; I replied, since that you feel already so good an effect of my medicament, I advise you to cast away all your Plaisters, onely keep the wound clean, and in a moderate temper 'twixt heat and cold.
This was presently reported to the Duke of _Buckingham_, and a little after to the King [James I.], who were both very curious to know the issue of the businesse, which was, that after dinner I took the garter out of the water, and put it to dry before a great fire; it was scarce dry, but Mr _Howels_ servant came running [and told me], that his Master felt as much burning as ever he had done, if not more, for the heat was such, as if his hand were betwixt coales of fire:
I answered, that although that had happened at present, yet he should find ease in a short time; for I knew the reason of this new accident, and I would provide accordingly, for his Master should be free from that inflammation, it may be, before he could possibly return unto him:
but in case he found no ease, I wished him to come presently back again, if not he might forbear coming. Thereupon he went, and at the instant I did put again the garter into the water;thereupon he found his Master without any pain at all.
To be brief, there was no sense of pain afterward:
but within five or six dayes the wounds were cicatrized, and entirely healed."[1]
