Suggestion in Colds.—Many remedies acquired a reputation for breaking up coughs and colds. It is, however, extremely doubtful whether any one has ever aborted a cold, or any other infection, that had gained a hold on the patient. We now know that this common affliction is not due to cold but to absorption of infectious material. Nansen spent two winters near the North Pole without catching any cold, and his men were as healthy as himself. He had been back in civilization scarcely a week before he and his men were confined to bed with a grippy cold. In the far north, and high on mountains where the temperature is low, colds are not as common as they are in crowded cities and especially among those who are much in crowds. Cold weather only predisposes to the infection, and after it has occurred it is sure to run its course. That course may be longer or shorter. The cold is usually preceded by chilly feelings. Every one knows it is possible to have chilly feelings that seem to portend a cold, yet be well the next day. If in the meantime any remedy is taken, credit will be given to the remedy. When a cold was supposed to be merely a disturbance of circulation or a congestion, one might expect to break it up. Now that we know that it is a microbic infection, and know further that microbic diseases are usually cured by a definite reaction on the part of the body, we are not so likely to think of breaking them up. There are still physicians who think they can abort a threatened pneumonia or abbreviate typhoid fever, but they are not those who know most about the science of medicine.
We have the story, then, of a series of remedies used with great confidence in coughs and colds, some of them physically beneficial, many of them, especially those containing opium, often physically harmful, yet taken with such confidence that undoubtedly the patient was helped through his mind if not otherwise. What is thus true for this class of diseases can also be said of other minor affections. Many internal remedies have been used for boils and styes and other external infections and have often had wide vogue. The reason for their acceptance as remedies has been that the giving of anything produces a more hopeful attitude in the mind of the patient and this, by bettering the general health, sometimes overcomes the tendency that may exist to a repetition of such infectious processes.
Erysipelas.—The medical history of erysipelas is just a succession of remedies recommended, each claimed to be almost infallible, yet abandoned after a time for another for which like exaggerated claims were made. The doctrine of signatures played a large rôle in the treatment of erysipelas, and, strange as it may seem, still survives. According to the doctrine of signatures, erysipelas, being a disease involving intense redness of the skin, red things in nature would be likely to do it good. Red pepper, for instance, was suggested for it over and over again, both internally and externally. Various red remedies have been favorites at different times in history. At present, in many country places, a poultice made of cranberries is supposed to be most efficacious. For many years I lived in a small town where one of the grocers put in a large stock of cranberries each fall, though the people of the neighborhood used them but little on the table, because during the winter there were many calls for them for the making of poultices for erysipelas. People who have had erysipelas, especially if it has occurred on unexposed portions of the body, are supposed to be protected against its recurrence—for there is a distinct liability to its recurrence—by the wearing of red flannels!
There is scarcely any drug that has not at some time been recommended as almost a specific for erysipelas. Anything that was given on the third or fourth day, and it was only at this time as a rule that patients came to physicians to be treated, seemed to bring about the alleviation of symptoms that occurred on the fifth or sixth day.
Erysipelas, because of the sudden irruption of fever which accompanies it, the intense redness which characterizes it, and the discomfort which is often present, is an affection that disturbs patients very much. For them, then, the presence of the physician and his assurance that their affection is not likely to be severe, and his prompt relief of certain conditions, all act by suggestion on the patient's mind and strengthen the natural curative reaction.
In country places where physicians were not near, erysipelas was one of the affections that continued almost down to our own day to be treated by incantations. I have known in a little American country town of a woman making a "charm," as it was called, for erysipelas.
Pneumonia.—Pneumonia is another of these sharply self-limited diseases that give opportunity to many remedies for the acquisition of a reputation as cures. Croupous pneumonia is so disturbing in its onset, so rapid in its progress, yet so strictly self-limited in the previously strong and healthy, that in the old days there were many remedies that were supposed to bring about the crisis. The old text-books contain so many cures that it is surprising pneumonia should have continued to be the fatal disease it has been at all times. Almost any remedy that is used for three or four days in pneumonia will be followed by the crisis with, in most cases, a favorable termination. The crisis takes place some time from the seventh to the tenth or eleventh day, and often we do not see a pneumonia patient until the second or third day of the disease. Just before the crisis the patient runs into a series of acute and more or less alarming symptoms. Often there is much restlessness, difficulty of breathing with complaint of heaviness, and perhaps prostration. The pulse and temperature are high, the skin hot and dry. Then in the midst of this the patient sleeps, there is a critical sweat, the temperature drops, the patient wakes up feeling quite well, there is little difficulty in breathing, and he feels that recovery is sure to come. The change is so great that it is natural that it should have been attributed to all sorts of remedies which had been used immediately preceding the crisis.
I once heard an old physician declare at a meeting of a large and important medical society that calomel in divided doses was practically a specific for pneumonia. He said he waited forty-eight hours to be sure that the affection was pneumonia, and also that it had reached that diffusion in the lungs beyond which it was not likely to go, then he gave the calomel. He said that, almost as a rule, during the next forty-eight hours the crisis came—and he attributed it to the calomel. We have had other remedies just as curious as this recommended and taken quite seriously. Some years ago a Russian physician, who had been treating soldiers in the Russian army for the pneumonia which occurs so commonly after exposure on the Steppes, announced that he had found in digitalis almost a specific. He pushed the tincture up to twenty drops three times a day, beginning it just as soon as the pneumonia was detected, and the rate of mortality among his patients was about one per cent. According to his theory, it was the failure of the heart in pneumonia that made the disease fatal.
Apparently the character of the patients in whom his pneumonias occurred was forgotten. They were absolutely the most favorable cases that could be selected. Most of them were young men between twenty and twenty-five. At this age no one who is given a reasonable amount of fresh air should die of pneumonia. If the patient had a serious heart lesion, or a crippled kidney from nephritis after scarlet fever, or crippled lungs because of a previous attack of tuberculosis, then the pneumonia might be fatal—indeed, almost inevitably would be, or, in the last-mentioned case, would end by lysis and not crisis. It really matters little what remedy is given to young, otherwise healthy, adults; they will get better, barring serious complications. The use of digitalis lessened the chances of recovery by stimulating too early in the case the heart that later had to bear one of the most serious strains that the organ can stand. But doubtless this harm was more than overcome by the patient's knowledge that he was taking a new and powerful remedy, supposed to be particularly calculated to cure him.
Moreover, the special interest of the physician in these cases, and his administration of a remedy with confidence which inspired the patient, undoubtedly did much good. Pneumonia is one of those diseases in which the patient is likely to be greatly depressed unless he is surrounded by favorable mental influences, and is encouraged to believe that he is going to get well. Every physician has probably had cases in which patients died, not because of the severity of the disease, but because they gave up the struggle in fright. If several of a man's friends have died of pneumonia during the year or two before he gets it, he is likely to conclude, especially if he is of the worrying kind, that his doom is sealed as soon as the diagnosis of pneumonia is made. If this thought persists hardly anything will save him. He must be assured that pneumonia is not necessarily serious, that there are remedies that influence it, and that his own case is particularly likely to respond favorably to them.
