A naturopathic doctor (ND) is a licensed healthcare provider who completes a four-year graduate-level medical program and treats patients using a combination of conventional diagnostics and natural therapies like clinical nutrition, herbal medicine, and lifestyle counseling. In the 23 states (plus Washington, D.C.) that regulate the profession, NDs can serve as primary care providers, order lab work, perform physical exams, and in some states prescribe certain medications.
Training and Education
Naturopathic doctors attend four-year, accredited naturopathic medical schools. The first two years focus on the same foundational biomedical sciences taught in conventional medical schools: anatomy, physiology, biochemistry, microbiology, immunology, pathology, pharmacology, and neuroscience. The final two years shift to supervised clinical training, where students work directly with patients under licensed practitioners.
There are currently seven accredited naturopathic programs in North America, including Bastyr University in Washington and California, National University of Natural Medicine in Portland, Sonoran University of Health Sciences in Arizona, National University of Health Sciences in Illinois, the Canadian College of Naturopathic Medicine in Ontario and British Columbia, and Universidad Ana G. Méndez in Puerto Rico. All are accredited by the Council on Naturopathic Medical Education.
After graduation, NDs must pass a two-part national licensing exam called the NPLEX. Part I covers biomedical sciences with 200 questions on anatomy, physiology, biochemistry, genetics, microbiology, immunology, and pathology. Part II is a case-based clinical exam with roughly 400 questions spanning diagnosis, botanical medicine, homeopathy, nutrition, physical medicine, pharmacology, and emergency medicine.
How ND Training Differs From MD Training
The biggest gap between naturopathic and conventional medical training comes after graduation. MDs and DOs complete a minimum of three years of residency (and up to seven for specialties like surgery or cardiology). For naturopathic doctors, postgraduate residency is neither common nor required, except in Utah, which mandates one year. Fewer than 10% of ND graduates enter an approved residency program, and those residencies typically last only one year.
This difference matters most for complex or acute medical conditions. NDs receive training in pharmacology and emergency medicine, but their clinical hours are weighted toward outpatient, primary-care settings rather than hospital-based care. Their education also includes subjects not covered in conventional medical school, such as botanical medicine, homeopathy, hydrotherapy, and counseling techniques.
Guiding Principles
Naturopathic medicine is built on six core principles that shape how NDs approach patient care. The first, often summarized as “the healing power of nature,” holds that the body has an inherent ability to heal itself, and the doctor’s job is to support that process and remove obstacles to recovery. The second is to identify and treat root causes of illness rather than simply suppressing symptoms.
“First do no harm” guides NDs to choose the least invasive, lowest-risk interventions before escalating. “Doctor as teacher” reflects the emphasis on patient education and shared responsibility for health outcomes. The remaining two principles, treating the whole person and prioritizing prevention, push NDs to consider physical, mental, emotional, environmental, and even spiritual factors when building a treatment plan, and to intervene early by assessing risk factors before disease develops.
What Treatments NDs Use
Naturopathic doctors draw from a broad toolkit. The most common modalities include:
- Clinical nutrition: Dietary plans built around whole, unprocessed foods, tailored to specific conditions. This is often the foundation of an ND’s treatment approach.
- Herbal medicine: Plant-based preparations used to support various body systems, from digestive health to immune function.
- Homeopathy: Highly diluted substances intended to stimulate the body’s self-healing response (though this remains one of the more controversial modalities, with limited evidence of efficacy beyond placebo).
- Physical therapies: Massage, acupressure, and other hands-on techniques.
- Hydrotherapy: Therapeutic use of water, such as hot and cold compresses to influence circulation.
- Counseling and stress management: Addressing emotional and psychological factors that affect healing, including lifestyle coaching.
Some NDs also recommend fasting protocols or use techniques like kinesiology, depending on their training and state regulations.
Prescribing Authority and Scope of Practice
What an ND can legally do varies dramatically by state. In states with the broadest scope, NDs function much like primary care physicians. Eight states currently allow naturopathic doctors to prescribe at least some controlled substances: Arizona, California, New Hampshire, New Mexico, Oregon, Utah, Vermont, and Washington.
Oregon gives NDs some of the widest prescribing rights, covering a broad range of prescription drugs including Schedule III through V controlled substances. Arizona allows NDs to prescribe most drugs and devices except Schedule II opioids. Washington permits limited controlled substances like codeine and testosterone products. California allows NDs to prescribe hormones, certain controlled substances, and legend drugs, though some require supervision by an MD or DO.
In states without licensing laws, the title “naturopathic doctor” may not be regulated at all, meaning someone could use the title without completing an accredited program. If you’re considering seeing an ND, checking whether your state is among the 23 that regulate the profession is an important first step.
What a Visit Looks Like
The patient experience with a naturopathic doctor feels notably different from a conventional primary care visit. An initial appointment typically runs 60 to 90 minutes, compared to the 20 minutes to one hour that’s standard in conventional medicine. That extra time goes toward a detailed health history covering not just your symptoms but your diet, sleep, stress levels, emotional health, and lifestyle habits.
Follow-up visits are generally shorter but still tend to be longer than a typical conventional appointment. NDs often spend significant time on patient education, explaining the reasoning behind dietary changes, supplement recommendations, or lifestyle modifications. The goal is for you to understand your treatment plan well enough to manage much of it on your own between visits.
Insurance and Cost
Coverage for naturopathic care is uneven. Medicare does not cover visits to naturopathic doctors. In states where NDs are licensed, many participate in private insurance plans and some accept Medicaid, but coverage is far from universal. You should expect to verify benefits with your insurer before booking an appointment, as many plans either exclude naturopathic services or limit the number of covered visits.
For patients paying out of pocket, initial consultations tend to cost more than a conventional office visit, reflecting the longer appointment times. Some NDs offer sliding-scale fees or package pricing for ongoing care. Supplements and herbal preparations recommended during visits are almost always an additional, out-of-pocket expense.
Who Naturopathic Care Works Best For
Naturopathic doctors tend to attract patients dealing with chronic conditions like digestive issues, fatigue, hormonal imbalances, autoimmune concerns, and stress-related health problems. People who want more time with their provider, a focus on prevention, and treatment plans that emphasize diet and lifestyle changes over pharmaceuticals often find the naturopathic approach appealing. Many patients see an ND alongside a conventional physician, using naturopathic care as a complement rather than a replacement.
For acute emergencies, surgical conditions, or complex diseases requiring hospital-based care, conventional physicians with their extended residency training and full prescribing authority remain the appropriate choice. The most practical approach for many people is understanding what each type of provider does well and using them accordingly.
