Certainly we fail, but our failures are usually due to the fact that sick people, as a rule, do not consider Nature Cure except as a last resort. The methods and requirements of Nature Cure appear at first so unusual and exacting that people seek to evade them so long as they have the least faith in the miracle-working power of the poison bottle, a metaphysical healer or the surgeon's knife. When health, wealth and hope are entirely exhausted, then the chronic sufferer grasps at Nature Cure as a drowning man clutches at a straw. But even though ninety percent of these cases which come to us are of the apparently incurable type, our total failures are few and far between.
If there is sufficient vitality in the body to react to natural treatment and if the destruction of vital parts and organs has not too far advanced, a cure is possible. Often the seemingly hopeless cases yield the most readily.
Our success is due to the fact that we do not rely on any one method of treatment, but combine in our work everything that is good in the different systems of natural healing.
