What naturopathic doctors do:
Naturopathic doctors (NDs) work to identify the 'root' or underlying cause of disease by spending a good amount of time getting to really know their patients; appointments are usually an hour in length as a result.
Naturopathic doctors are trained very similarly to family doctors (general practitioners), especially in labs, diagnostic testing, physical exams, and everything else that is required to come up with a diagnosis.  However, our training differs in the treatments we are taught.  NDs don't prescribe pharmaceutical drugs but treat conditions using lifestyle counselling, natural medicines (herbal teas, vitamin and mineral supplements, etc.), dietary modification, acupuncture, and more.  Naturopathic medicine also focuses heavily on preventative medicine.  Unlike some alternative health practitioners, NDs are not anti-mainstream-medicine and are happy to collaborate with other doctors to ensure that patients receive the best of both medical worlds.
