The conjunction of the bark with the cold bath stands indicated by the purity of their virtues; they operated the same effects, and being combined, they cure those disorders which all the other remedies only serve to make worse. In their qualities of strengthening, of anodynes, of febrifuges, they re-invigorate, they lessen the feverish and nervous heat, they calm the irregular motions produced by the spasmodic disposition of the nervous system. They remedy the weakness of the stomach, and very quickly dissipate the pains which are the consequences of it. They restore appetite, facilitate the digestion and nutrition, they re-establish all the secretions, and especially perspiration, which renders them so efficacious in all the catarrhal and cutaneous disorders; in short, they are remedies for all the diseases caused by weakness, provided that the patient does not labor under indissoluble obstructions, inflammations, abscesses, or internal ulcers, conditions which even do not necessarily or almost necessarily exclude, any thing more than the cold baths, but which often allow of the bark. I saw, some years ago, a foreigner, who might be of the age of about twenty-three or twenty-four, and who, from his tenderest infancy, had been subject to the torture of the cruellest head-achs, and almost continual ones considering the frequency and the length of the fits, which were almost always accompanied with a total loss of appetite. The evil had been considerably made worse by the use of bleeding, of evacuatives, of purgative waters, of warm baths, of broths, and a multitude of other remedies. I prescribed for him the cold bath and the bark. In a few days, the fits became weaker and weaker, and much less frequent; the patient, at a month’s end, thought himself almost radically cured; the cessation of the remedies and the bad weather renewed the fits, but incomparably less violent than before. He recommenced the same process of cure the spring following, and his disorder came to be so slight, that he judged he should need no more of any application; I am persuaded that the same recourse, once or twice repeated, will radically cure him.
