Nature cure is a system that aims to build up the entire being in harmony with nature's constructive principle on physical, mental, moral, and spiritual levels. It views health as normal vibration in harmony with nature and disease as abnormal vibration caused by violating nature's laws. The primary cause of disease is lowered vitality, abnormal blood composition, and waste accumulation. Chronic disease occurs when morbid buildup prevents the body's natural healing crises from correcting conditions. Cure involves readjusting the body from abnormal to normal functions through establishing natural surroundings and habits, conserving vital force, improving blood quality, eliminating waste safely, and promoting self-help and personal responsibility.
