The following principles are the foundation for the practice of naturopathic medicine: 

The Healing Power of Nature (Vis Medicatrix Naturae) 
The healing power of nature is the inherent self-organizing and healing process of living systems that establishes, maintains, and restores health. Naturopathic medicine recognizes this healing process to be ordered and intelligent. It is the naturopathic physician's role to support, facilitate and augment this process by identifying and removing obstacles to health and recovery, and by supporting the creation of a healthy internal and external environment. 

Identify and Treat the Causes (Tolle Causam) 
Illness does not occur without cause. Causes may originate in many areas. Underlying causes of illness and disease must be identified and removed before complete recovery can occur. Symptoms can be expressions of the body's attempt to defend itself, to adapt and recover, to heal itself, or maybe results of the causes of disease. The naturopathic physician seeks to treat the causes of disease, rather than to merely eliminate or suppress symptoms. 

First Do No Harm (Primum Non Nocere) 
Naturopathic physicians follow three precepts to avoid harming the patient: 

• Naturopathic physicians utilize methods and medicinal substances which minimize the risk of harmful effects and apply the least possible force or intervention necessary to diagnose illness and restore health. 

• Whenever possible the suppression of symptoms is avoided as suppression generally interferes with the healing process.

•  Naturopathic physicians respect and work with the vis medicatrix naturae in diagnosis, treatment, and counseling, for if this self-healing process is not respected the patient may be harmed.

Doctor as Teacher (Docere) 
The original meaning of the word "doctor" is the teacher. A principal objective of naturopathic medicine is to educate the patient and emphasize self-responsibility for health. Naturopathic physicians also recognize and employ the therapeutic potential of the doctor-patient relationship. 

Treat the Whole Person 
Health and disease result from a complex of physical, mental, emotional, genetic, environmental, social, and other factors. Since total health also includes spiritual health, naturopathic physicians encourage individuals to pursue their personal spiritual development. Naturopathic medicine recognizes the harmonious functioning of all aspects of the individual as being essential to health. The multifactorial nature of health and disease requires a personalized and comprehensive approach to diagnosis and treatment. Naturopathic physicians treat the whole person, taking all of these factors into account. 

Prevention 
Naturopathic medical colleges emphasize the study of health as well as disease. The prevention of disease and the attainment of optimal health in patients are the primary objectives of naturopathic medicine. In practice, these objectives are accomplished through education and the promotion of healthy ways of living. 

Naturopathic physicians assess risk factors, heredity, and susceptibility to disease, and make appropriate interventions in partnership with their patients to prevent illness. Naturopathic medicine asserts that one cannot be healthy in an unhealthy environment and is committed to the creation of a world in which humanity may thrive. 

Naturopathic Methods: 
Naturopathic medicine is defined primarily by its fundamental principles. Methods and modalities are selected and applied based upon these principles in relationship to the individual needs of each patient. Diagnostic and therapeutic methods are selected from various sources and systems and will continue to evolve with the progress of knowledge. 

Naturopathic Practice: 
Naturopathic practice includes the following diagnostic and treatment modalities: utilization of all methods of clinical and laboratory diagnostic testing including diagnostic radiology and other imaging techniques; nutritional medicine, dietetics, and therapeutic fasting; medicines of mineral, animal, and botanical origin; hygiene and public health measures; naturopathic physical medicine including naturopathic manipulative therapies; the use of water, heat, cold, light, electricity, air, earth, electromagnetic and mechanical devices, ultrasound, and therapeutic exercise; homeopathy; psychotherapy and counseling; acupuncture, injection and intravenous therapy; minor surgery; prescription medication; and naturopathic obstetrics (natural childbirth).
