This section is from the "Nature Cure: Philosophy and Practice Based on the Unity of Disease and Cure" book, by Henry Lindlahr.
The following paragraphs will explain the fundamental difference between neurotherapy and the older systems of manipulative treatment. The older systems, the same as the allopathic school of medicine, look upon acute diseases as destructive processes dangerous to health and life; therefore they endeavor to check or suppress them as quickly as possible by their various methods.
Neurotherapy so far is the only system of manipulative treatment that bases its work on the fundamental laws of Natural Therapeutics. According to these laws every acute disease is the result of a purifying, healing effort of Nature. Therefore neurotherapy would not suppress acute processes by manipulative treatment any more than by drugs, ice, antitoxins, surgery or any other suppressive method.
To illustrate: Supposing that spontaneously or as a result of natural living and treatment a patient suffering from chronic constipation, indigestion, etc., develops a vigorous purging, which we of the Nature Cure school would consider a splendid healing crisis. Under allopathic as well as under the treatment of other manipulative schools such an acute reaction would be immediately suppressed. This can be accomplished very easily by a few manipulative moves, but it would mean the suppression of a purifying healing crisis and this would result in throwing the patient back into his old chronic condition. The underlying causes of disease must be removed before we can cure chronic disease and bring about a normal condition of the organism.
Suppose manipulative treatment should succeed in stopping a fever instantaneously. This would suppress Nature's purifying, regenerating efforts, the patient would continue to "load up" more morbid materials (especially since these schools do not teach the importance of natural living) and it would only be a matter of time until the morbid accumulations in the body would excite new acute reactions, necessitating more adjustments. This may be all right for the practitioner; but what about the patient? In the long run it can only have one result, and that is chronic disease.
