(e) Three dr. euphorbium, 6 dr. powdered cantharides, 4 dr. Venice turpentine, 4 oz. alcohol. Macerate the euphorbium and cantharides with the alcohol for 48 hours, strain, and add the Venice turpentine; spread on French tissue-paper with a soft brush—size of each sheet about 18 by 24 in. This article is in much repute for the cure of corns and bunions, and the relief of gout.
(f) Dissolve 1 part salicylic acid in 40 of collodion: apply several times a week. The corn dissolves with little trouble.
(g) For hard corns apply at night a mixture of 1 part carbolic acid, and 10 of distilled water, glycerine, and soap liniment. Envelop with guttapercha tissue, and the corn may generally be removed the next morning.
(h) Gezou’s remedy for corns and warts is prepared as follows:—30 gr. salicylic acid, 10 gr. ext. cannabis indica, ½ oz. collodion.
(i) Fasten a piece of lemon on the corn, and renew night and morning. Simple but very effective.
Diarrhœa and Dysentery.—Beyond everything stands a strict regulation of the diet. When the intestinal canal is in a diseased state almost any substance introduced into the stomach acts mischievously, and it is not infrequently necessary to suspend all food until the intestine is in a condition to bear it. Every solid article is then mischievous, but even fluids, by reason of their temperature, may act as prejudicially. In most cases taking a few spoonfuls of warm soup, or drinking a mouthful of cold water will immediately be followed by severe colics, and soon afterwards by evacuations. Only allow lukewarm soups or other drinks, and only by a spoonful at a time. Of course these stringent rules apply to very obstinate diarrhœa, and especially dysentery, for there are many cases of temporary diarrhœa in which the patients continue to eat fruits and the like, and still soon get well. Such cases must, however, not be taken into account, and it is always most prudent at the commencement of diarrhœa to cut off the supply of food as far as possible, and at all events to prohibit all articles likely to augment the affection.
Opium is the most valuable medicine in diarrhœa, for it keeps the sphincter in a state of permanent contraction, a contraction which is often propagated to the large intestine, and the small intestine is unable to propel its contents far enough to induce the irritation which causes their expulsion. When, by reason of this contraction, these contents are retained, their amount may become considerably diminished by the absorption of the fluid. Frequently, however, there is no spot of the canal which is not so diseased as to prevent such absorption taking place, and then the diarrhœa will continue in spite of the opium and of the contraction of the sphincter. It appears, moreover, that opium, besides its action on the muscular portion of the canal, exerts, by contact, a soothing effect upon the mucous membrane. In consequence of the diminution of the irritation of this membrane, its secretion is probably lessened, as are possibly those of the liver and pancreas. However this may be, opium acts very favourably in profuse secretion from the intestinal mucous membrane. From ½-3 gr. may be given in the 24 hours, the best preparation being the ext. opii aquosum.
If opium or morphia do not suffice, it must be aided by astringent remedies, by far the best of which, and the most easily supported, is zinc sulphate. One would have supposed that tannin in its separate state would have proved more useful than zinc, but this is not the case, and it is much less easily borne. It acts much better and more energetically when employed as a household remedy (e.g. as a decoction of sloe or wild pear tree) than in its separated form, and is then of great service in practice among the poor. Alum is of no use whatever in diarrhœa. Lead approaches zinc in efficacy, but still it is less certain than it. The dose should not be greater than ¼ gr., and this may be repeated every 2-3 hours, and at most every hour. If these means do not suffice, we must have recourse to enemata of salep or starch (with which may be combined 1 gr. opium or ½ gr. zinc) not throwing up more than 2 oz. at a time. If the clyster does not cause pain in the rectum, and the disease continues obstinate, the dose of zinc may be increased to 2 gr. Tannin may be added to the enema, but the zinc is far more serviceable. In the most obstinate cases we must have recourse to cauterisation; but this is only the case when there is a diseased condition of the lower part of the rectum. Very obstinate cases of blenorrhœa confined to the anus maybe completely cured by the application of silver nitrate, in substance as high as it can be passed. The injection of a strong solution does not usually attain the same end. (Prof. Skoda.)
A case of chronic diarrhœa, which had lasted for nearly 40 years, was cured by the administration of a saturated solution of salt in cider vinegar, 1 dr. being taken 3 or 4 times a day; it always produces good results.
For cholera, a ready remedy is Dr. Rubini’s tincture of camphor, taken on sugar, not in water. Or 1 teaspoonful cayenne pepper in ½ wine glass brandy.
