That disease of the finger or toe commonly called a run-round, may be easily cured by a remedy so simple that persons who have not seen it tried are generally incredulous as to its efficacy. The first symptoms of the complaint are heat, pain, swelling, and redness at the top of the nail. The inflammation, if not checked, will soon go round the whole of the nail, causing intense pain, accompanied by a festering or gathering of yellow matter, and ending in the loss of the nail. To prevent all this, as soon as the first symptoms of swelling and inflammation commence, lay the finger flat on the table, and let the nail be scratched all over with the sharp point of a pair of scissors, or a penknife. This excoriation must be done first crossways, and then lengthways, so as thoroughly to scratch up the whole surface of the nail, leaving it rough and white. This little operation does not give the slightest pain; and we have never, in a single instance, known it fail. By next morning the finger will be well. If done before the festering commences, it is a certain and speedy cure. And it will even succeed at a later stage of the disease, by first opening with a needle, that part of the swelling where the yellow matter has begun to appear; and afterwards by scratching up the surface of the nail with scissors or penknife.
Hard horny warts on the hands can be cured positively, and without pain, by touching their tops twice a day or more with a clean quill pen, dipped in aquafortis. The wart, after a few applications of the aquafortis, will turn brown, and crumble till it falls off.
For ring-worms there is no remedy so good as mercurial ointment, rubbed on it at night, and not washed off till morning. It causes no pain, and by repetition will always effect a cure.
