MEDICINES that are sure cures for all the diseases to which humanity is heir, are not the spurious discoveries of the quacksalver and patent-medicine vender alone, but some very intelligent persons believe that if there is not a panacea, there is at least a remedy, for every disease. In cases where the patient does not recover, they believe that either the disease was not thoroughly understood or the medicines which were given were not properly selected. This is a great error, because there is no such thing as a specific or infallible remedy for any disease, and, on the other hand, it is quite possible that most patients, with proper nursing and diet, would naturally recover without any drugs or medicines whatever. Outside of those drugs, like ether, chloroform, opium, or morphine, that are employed for the purpose of deadening the sensibility of the nerves, so as to render them insensible to pain, there is not another drug that is absolutely sure and true in its medical effects. Some few are very useful at times, but the great bulk of medicines do much more harm than good. Medicine in its broad sense means a knowledge of the cause, course, treatment and ultimate results of disease. The study of medicine cannot be circumscribed by dogma or theory, nor can it be mastered in a few short years of study at the very best medical schools. It requires a mind adapted by nature for a plodding investigation of her laws, and incessant application, long after the college curriculum is ended. In fact, the student must unlearn much of the stereotyped lessons of the text-books, and this is particularly true of the supposed medicinal effects of drugs, which are always exaggerated. When physicians really have a threatening case, under their observation and care, the attributed therapeutic action of drugs is nearly always disappointing, and very often injurious, and they are forced to let the drugging entirely alone, and bring their skill to bear on measures which support the strength and vitality of the system, so that nature can effect a cure in her own way. This may seem to some simple doctoring, but I can assure the reader that it requires the highest degree of medical skill, notwithstanding the droll sarcasm of Voltaire, that “medical science is the art of amusing the patient while nature performs the cure.” There is neither skill nor much learning required to give an ordinary prescription; that the average apothecary could do with the greatest exactness. But science and medical skill can be exhausted in managing and husbanding the resources of nature, in order to effect a cure. Medicine no longer stands alone as a simple art, based on theoretical deductions, as it was less than a hundred years ago, but it has become a department of natural science, a part of the natural history of the human race.
