If the corn be properly and wholly removed, it will leave a small cavity or round hole in the center, where the blood-vessels and the nerve of the corn—vulgarly called the root—really were, and which, in point of fact, constituted the very existence or the essence of the corn. Moreover, if the corn be entirely removed, you will, without giving yourself the slightest pain, be able to squeeze the part affected between your finger and thumb.
Hard corns on the sole of the foot and on the sides of the foot are best treated by filing—by filing them with a sharp cutting file (flat on one side and convex on the other), neither too coarse nor too fine in the cutting. The corn ought, once every day, to be filed, and should daily be continued until you experience a slight pain, which tells you that the end of the corn is approaching. Many cases of hard corn, that have resisted every other plan of treatment, have been entirely cured by means of the file. One great advantage of the file is, it cannot possibly do any harm, and may be used by a timid person, by one who would not readily submit to any cutting instrument being applied to the corn.
The file, if properly used, is an effectual remedy for a hard corn on the sole of the foot. I myself have seen the value of it in several cases, particularly in one case, that of an old gentleman of ninety-five, who had had a corn on the sole of his foot for upwards of half a century, and which had resisted numerous, indeed, almost innumerable remedies; at length I recommended the file, and after a few applications entire relief was obtained, and the corn was completely eradicated.
The corns between the toes are called soft corns. A soft corn is quickly removed by the strong acetic acid—acid. acetic. fort.—which ought to be applied to the corn every night by means of a camel’s-hair brush. The toes should be kept asunder for a few minutes, in order that the acid may soak in; then apply between the toes a small piece of cotton wool.
Hard corns, then, on the sole and on the side of the foot, are best treated by the file; hard corns on the toes by the scissors; and soft corns between the toes by the strong acetic acid.
In the generality of cases the plans recommended above, if properly performed, will effect a cure; but if the corn, from pressure or from any other cause, should return, remove it again and proceed as before directed. If the corn have been caused either by tight or by ill-fitting shoes, the only way to prevent a recurrence is, of course, to have the shoes properly made by a clever shoemaker—by one who thoroughly understands his business, and who will have a pair of lasts made purposely for the feet.[[310]]
The German method of making boots and shoes is a capital one for the prevention of corns, as the boots and shoes are made scientifically, to fit a real and not an ideal foot.
One of the best preventives of, as well as of the best remedies for corns, especially of soft corns between the toes, is washing the feet every morning, as recommended in a previous Conversation,[[311]] taking especial care to wash with the thumb, and afterward to wipe with the towel between each toe.
375. What is the best remedy to destroy a Wart?
Pure nitric acid,[[312]] carefully applied to the wart by means of a small stick of cedar wood, a camel’s-hair pencil-holder, every other day, will soon destroy it. Care must be taken that the acid does not touch the healthy skin, or it will act as a caustic to it.
