Now as we need not, cannot feed the brain in time of sickness, what can we feed? In all diseases in which there are a high pulse and temperature, pain or discomfort, aversion to food, a foul, dry mouth and tongue, thirst, etc., wasting of the body goes on, no matter what the feeding, until a clean, moist tongue and mouth and hunger mark the close of the disease, when food can be taken with relish and digested. This makes it clearly evident that we cannot save the muscles and fat by feeding under these adverse conditions.
Another very important, unquestioned fact is that disease in proportion to its severity means a loss of digestive conditions and of digestive power.
Cheer is to digestion what the breeze is to the fire. It may well be conceived that there are electric nerve wires extending from the depths of the soul itself to each individual gland of the stomach, with the highest cheer or ecstacy to stimulate the highest functional activity, or the shock of bad news to paralyze. From cheer to despair, from the slightest sense of discomfort to the agony of lacerated nerves, digestive power goes down. Affected thus, digestive power wanes or increases, goes down or up, as mercury in a barometer from weather conditions.
Digestive conditions in their maximum are revealed in the school-yard during recess, when Nature seems busy recovering lost time.
How compares the ramble of a June morning, with the blue and sunshine all above, the matchless green of the trees, and all the air fragrant with the perfume of flowers and alive with music from the winged singer, in digestive conditions, with those in the rooms of the sick, where there is only distress felt in the body and seen in the faces of the friends?
In time of health, if we eat when we are not hungry, or when very tired, or in any mental worriment, we find that we suffer a loss of vital power, of both physical and mental energy. How, then, can food be a support to vital power when the brain is more gravely depressed by disease? Yet from the morning of medical history the question of how vital power is supported in time of sickness has never been considered, because there has never been any doubt as to the support coming from food. I assume this to be a fact, since all works on the practice of medicine of to-day enjoin the need to feed the sick to sustain their depressed energies—all this without a question as to whether there is not a possibility of adding indigestion to disease when food is enforced against Nature's fiat.
Since vital power is centred in the brain, do we need to feed, can we feed, for other than brain reasons? This physiology admitted, there is no other conclusion possible than that feeding the sick is a tax on vital power when we need all that power to cure disease.
With all this physiology behind me, for more than a score of years I have been going into the rooms of the sick to see the evolutions of health from disease, as I see the evolutions from the dead wastes of March to the affluence of June, and from the first I had the exceeding advantage of being able to study the natural history of disease, a history in which none of the symptoms were aggravated by digestive disturbances.
As there was no wasting of vital power in the hopeless effort to save the body from wasting, I had a clear right to presume that my patients recovered more rapidly and with less suffering. With no perplexing study over what foods and what medicines to give, I could devote my entire attention to the study of symptoms as evidences of progress toward recovery or death; and in addition to all this there was the great satisfaction of being strictly in line with Nature as to when and what to eat.
As to the danger of death from mere starvation, the following remarkable case reveals how remote it is in the ordinary history of acute diseases. The late Rev. Dr. Merchant, of Meadville, Pa., a short time before his death, which occurred some months ago, informed me that a brother entered the army during the War of the Rebellion with a weight of one hundred and fifty-nine pounds. He was sent home so wasted from ulceration of stomach and bowels that he actually spanned his thigh with thumb and finger. He lived ten days only, to astonish all by the clearness of his mind even on the last day of his life, when he could think on abstruse questions as he had never been known to do in health. At death his body weighed only sixty pounds.
