Stressing prevention and honoring the healing power of nature, Naturopathic medicine relies upon natural therapies including diet, nutritional medicine, herbs, homeopathy, acupuncture, massage and bodywork as well as psychological and lifestyle counseling. The patient is able to utilize a combination of therapies determined by the naturopath at very safe dosages, rather than a using a single therapy at a higher, toxic dosage. Naturopathy also views the role of the physician to be an educator, teaching and motivating people to take more personal responsibility in maintaining good health and a state of wellness.

Dr. Pizzorno's naturopathic approach to treating depression identifies five primary determinants of mood: physical factors; social factors (family and social patterns), mental factors (a person's thinking patterns), emotional factors and spiritual factors. For example, on the physical level we may need to eliminate toxins, normalize endocrine function and neurotransmitter metabolism, increase exercise and light exposure, and utilize natural mood elevators. On the mental and emotional levels we may need to deal with family of origin issues, employ psychodynamic approaches when necessary, or even follow a prescription for having fun if we are in need of lightening up our lives.
