This section is from the "Nature Cure: Philosophy and Practice Based on the Unity of Disease and Cure" book, by Henry Lindlahr.
We must not forget that health or disease, in the final analysis, is resident in the cell. Though a minute, microscopic organism, the cell is an independent living being, which is born, grows, eats, drinks, throws off waste matter, multiplies, ages and dies, just like man, the large cell. If the individual cell is well, man, the complex cell, is well also, and vice versa. From this it is apparent that in all our considerations of the processes of health, disease and cure, we have to deal primarily with the individual cell.
The vibratory activity of the cell may be lowered through the decline of vitality brought about in a natural way by advancing age, or in an artificial way through wrong habits of living, wrong thinking and feeling, overwork, unnatural stimulation and excesses of various kinds.
On the other hand, the inflow of vital force into the cells may be obstructed and their vibratory activity lowered by the accumulation of waste and morbid matter in the tissues, blood vessels and nerve channels of the body. Such clogging will interfere with the inflow of life force and with the free and harmonious vibration of the cells and organs of the body as surely as dust in a watch will interfere with the normal action and vibration of its wheels and balances.
From this it is evident that negative conditions may be brought about not only by hyperrefinement of the physical organism, but also by clogging it with waste and morbid matter which interfere with the inflow and distribution of the vital force. It also becomes apparent that in such cases the Nature Cure methods of eliminative treatment, such as pure food diet, hydrotherapy, massage, chiropractic, osteopathy, etc., are valuable means of removing these obstructions and promoting the inflow and free circulation of the positive electric and magnetic life currents.
