A Naturopathic Physician (ND) is an expert in natural medicine. Naturopathic medicine concentrates on whole-patient wellness – the medicine is tailored to the patient and emphasizes prevention and self-care. Naturopathic medicine attempts to find the underlying cause of the patient’s condition rather than focusing solely on symptomatic treatment. For example, congestion might be caused by a food intolerance or environmental factor – a Naturopathic physician would focus diagnosis and treatment on these causal factors. Naturopathic physicians cooperate with all other branches of medical science referring patients to other practitioners for diagnosis or treatment when appropriate.
