Naturopathic medicine is a field of medicine that recognizes the body's innate ability to heal, given optimal conditions to do so. It examines root causes for disease manifestations and seeks to treat those root causes, rather than suppress symptoms. Naturopathic doctors are trained in conventional pharmacology in order to integrate conventional with naturopathic care. 

A typical visit with a Naturopathic doctor (ND) involves an extensive look into everything that is part of you. Your ND can order indicated testing to diagnose conditions and offer a variety of treatment options.
