For an Ague:—Make six middling pills of cobwebs. Take one a little before the cold fit; two a little before the next fit (suppose the next day); the other three, if need be, a little before the third fit. This seldom fails.
A Cut:—Bind on toasted cheese. This will cure a deep cut.
A Fistula:—Grind an ounce of sublimate mercury as fine as possible.... (Two quarts of water to be added, then half a spoonful with two spoonfuls of water to be taken fasting every other day), ... In forty days this will also cure any cancer, any old sore or King’s evil.
The Iliac Passion:—Hold a live puppy constantly on the belly.
John Wesley (Primitive Physic. Ed. 1780).
The iliac passion, now known as ileus, is a severe colic due to intestinal obstruction.
It seems strange that so eminent a man should have believed in these absurd prescriptions, but as a matter of fact the book generally is much more sane and sound than one would expect from the habits and state of knowledge of the time. For example, in his rules of health Wesley strongly advises the practice of cold bathing, cleanliness, open-air exercise, moderation of food, etc. Also these prescriptions are chosen for their absurdity—in each case other more sensible remedies are offered. But Wesley in his preface says that he has omitted altogether from his book Cinchona bark, because it is “extremely dangerous.” This means that in regard to ague he omitted the only efficient remedy—which was much more unfortunate than his prescribing cobweb pills.
This book went to thirty-six editions between 1747 and 1840.
