In Ingram's Patterns Of Madness In The Eighteenth Century: A Reader, it is noted that Wesley saw disease as a consequence of the Fall and thus regarded mankind as primarily responsible for its own sufferings. Wesley says as much in his preface:
"When man came first out of the hands of the Great Creator, clothed in body, as well as in soul, with immortality and incorruption, there was no place for physic, or the art of healing. As he knew no sin, he knew no pain, no sickness, weakness, or bodily disorder ... But since man rebelled against the Sovereign of heaven and earth, how entirely is the scene changed! ... The seeds of wickedness and pain, of sickness and death, are now lodged in our inmost substance; whence a thousand disorders continually spring, even without the aid of external violence."
Wesley covered the common illnesses of his day in alphabetical order; mental illnesses, curiously, are not distinguished from physical ailments, as in Wesley's view both are derived from man's first disobedience. They are thus stigmatised no more than other illnesses.
What follows are Wesley's interesting and amusing remedies for various types of psychological conditions, especially the mania associated with rabies:
44. An Hysteric Cholic.
164. Mrs. Watts, by using the cold bath two and twenty times in a month, was entirely cured of an hysteric cholic, fits, and convulsive motions, continual sweatings and vomiting, wandering pains in her limbs and head, with total loss of appetite.
169. Or, twenty drops of laudanum, in any proper clyster, which gives instant ease.
469. Or, rub the head several times a day with vinegar, in which ground-ivy leaves have been infused:
470. Or, daily take an ounce of distilled vinegar:
471. Or, boil juice of ground-ivy with sweet oil and white wine into an ointment. Shave the head, anoint it therewith, and chafe it every other day for three weeks. Bruise also the leaves and bind them on the head, and give three spoonfuls of the juice warm every morning.
472. Or, be elecrified: tried.
152. Raging Madness.
473. Apply to the head, cloths dipt in cold water:
474. Or, set the patient with his head under a great water-fall, as long as his strength will bear: or, pour water on his head out of a tea-kettle:
475. Or, let him eat nothing but apples for a month:
476. Or, nothing but bread and milk: tried.
477. Plunge into cold water daily for twenty days, and keep as long under as possible. This has cured, even after the hydrophobia was begun.
478. Or, mix ashes of trefoil with hog's-lard, and anoint the part as soon as possible. Repeat it twice or thrice at six hours distance. This has cured many: and particularly a dog bit on the nose by a mad dog.
479. Or, mix a pound of salt, with a quart of water. Squeeze, bathe, and wash the wound with this for an hour. Then bind some salt upon it for twelve hours.
N.B. The Author of this receipt was bit six times by mad dogs, and always cured himself by this means.
480. Or, mix powdered liver-wort, four drachms: black pepper, two drachms. Divide this into four parts, and take one in warm milk for four mornings, fasting. Dr. Mead affirms he never knew this to fail: but it has sometimes failed.
481. Or, take two or three spoonfuls of ribwort, morning and evening, as soon as possible after the bite. Repeat this for two or three changes of the moon. It has not been known to fail.
482. Immediately consult an honest physician.
