Some naturopaths equate this healing power to the vital force idea that underlies the traditional healing systems from many ancient cultures. A related emphasis is placed on uncovering and treating the cause of disease, instead of merely relieving symptoms. Other naturopathic principles include avoiding drugs and surgery in favor of natural methods. Naturopaths pay close attention to a person's lifestyle and medical history. They strive to treat the whole person, which includes lifestyle, environment, and other factors that affect well-being.
Naturopathic medicine uses several methods that vary in how effective they are.
Some naturopathic methods, such as homeopathy, may be of little value. However, others are thought to be effective. Examples include the importance of diet in lowering the risk of severe illnesses such as heart disease and cancer, and the use of acupuncture to reduce pain and to help with drug addiction. Researchers at the University of Minnesota Medical School studied naturopathic treatments and found some supporting scientific evidence in their favor. But they also pointed out a need for more clinical trials.
