Varies significantly by state. About 25 states license naturopathic doctors (ND). In those states, a license is required to practice. In the remaining states, naturopathic practice is largely unregulated — but title restrictions may still apply and practitioners must avoid crossing into unlicensed medical practice.
State-by-State Naturopathy Licensing Requirements
Naturopathic doctor (ND) licensing represents one of the most complex licensing landscapes in holistic health. Unlike aromatherapy or Reiki, naturopathy has a well-developed licensing system in approximately half the states — making state-specific knowledge essential for every naturopathic practitioner.

Arizona and Oregon have among the most comprehensive ND scopes of practice, including limited prescribing rights for pharmaceutical agents, minor surgery, and primary care responsibilities. Washington, New Mexico, and Nevada also provide robust ND practice authority. These states are often chosen by NDs who want the broadest clinical scope for integrative primary care practice.
Unlicensed States — Naturopathic Practice is Not Formally Regulated
In approximately 25 states including Texas, Florida, Georgia, New York, Illinois, Ohio, Pennsylvania, and many others, naturopathic medicine is not a licensed profession. Traditional naturopathic practitioners can offer wellness education and natural health information within scope. However, they must not diagnose, prescribe, or hold themselves out as licensed healthcare providers.
In unlicensed states, use of the title "Naturopathic Doctor" or "ND" may still be restricted under medical practice acts — using these titles without a license in a state that prohibits unlicensed use of medical titles can constitute practicing medicine without a license. Always check your state's specific title restrictions. "Traditional Naturopath," "Naturopathic Consultant," or "Natural Health Educator" are commonly used non-clinical titles in unlicensed states. Consult with a healthcare attorney before establishing a practice in an unlicensed state.
How to Become a Licensed Naturopathic Doctor
Licensure as a naturopathic doctor requires completing one of the most rigorous credentialing pathways in natural medicine.
Complete a CNME-Accredited 4-Year ND Doctoral Program
The Council on Naturopathic Medical Education (CNME) accredits naturopathic doctoral programs. Accredited schools include Bastyr University (Seattle & San Diego), National University of Natural Medicine (Portland), Southwest College of Naturopathic Medicine (Tempe), Canadian College of Naturopathic Medicine (Toronto), and National Health Sciences University. Programs cover all biomedical sciences, naturopathic therapeutics, clinical rotation, and specialty training.
Pass NPLEX Parts I and II
The Naturopathic Physicians Licensing Examinations (NPLEX), administered by the North American Board of Naturopathic Examiners (NABNE), are the standardized board exams for ND licensure. Part I (Biomedical Science) covers anatomy, physiology, biochemistry, microbiology, pathology, and pharmacology, and is typically taken during ND school. Part II (Clinical Science) covers naturopathic clinical assessment, diagnosis, and therapeutics, and is taken after graduation. Most licensed states require passing both parts.
Apply for State License
Submit a license application to the naturopathic licensing board (or medical/health licensing board) in your state. Requirements typically include: official NPLEX score transcripts from NABNE, official ND degree transcript, completed application form with fees, background check, and sometimes a state-specific jurisprudence examination. Processing times vary from 4–12 weeks. Some states require additional documentation of supervised clinical hours.
Maintain License with Continuing Education
Maintain your ND license through state-mandated continuing education. Most licensed states require 30–60 CE hours per renewal period (typically every 1–2 years). CE must often include specific required topics such as pharmacology, ethics, cultural competency, or pain management. AANP (American Association of Naturopathic Physicians) annual conferences and online CE providers offer accredited programming. License renewal also requires payment of renewal fees and confirmation of active malpractice insurance.
What Credentials Exist for Naturopathic Practitioners?
ND License — State-Issued Naturopathic Doctor License
The ND state license is the primary and most rigorous credential in naturopathic medicine. It is issued by state licensing boards to graduates of CNME-accredited ND programs who have passed NPLEX. Where required, it is a legal prerequisite to practice. Licensed NDs hold one of the most rigorously credentialed positions in natural medicine, having completed the equivalent of a medical school curriculum alongside naturopathic training.
NPLEX — Naturopathic Physicians Licensing Examinations (NABNE)
NPLEX scores, administered by NABNE, are the portable evidence of board examination achievement. Your NABNE NPLEX transcripts accompany every state license application and serve as the national standard for ND clinical competency verification. NABNE maintains NPLEX records indefinitely for license application purposes across all states.
AANP Member — American Association of Naturopathic Physicians
AANP is the primary national professional membership organization for licensed naturopathic doctors. AANP membership provides advocacy, continuing education, national referral network access, policy resources, and the professional community of licensed NDs. AANP also maintains legislative tracking for ND licensing expansion efforts across unlicensed states.
CNME-Accredited ND Degree
Graduation from a CNME (Council on Naturopathic Medical Education)-accredited program is the foundational credential for ND licensure. CNME accreditation ensures the program meets rigorous academic and clinical training standards. CNME-accredited schools include Bastyr University, NUNM (National University of Natural Medicine), SCNM (Southwest College of Naturopathic Medicine), CCNM (Canadian College of Naturopathic Medicine), and others. Degrees from non-CNME-accredited programs are not accepted for ND licensure in any licensed state.
ICONIC Board Credential
ICONIC Board credentials recognize holistic health practitioners operating to documented professional practice standards. Licensed NDs already hold one of the most rigorous credentials in natural medicine — ICONIC Board adds professional practice recognition that documents ethics, continuing education commitment, and holistic practice standards beyond minimum ND licensing requirements. For traditional naturopaths in unlicensed states, ICONIC Board is especially valuable: it establishes professional credibility in the absence of state licensing.
Where ICONIC Board Fits in Naturopathic Practice
Complementing the Gold Standard — and Filling the Gap
Licensed NDs already hold one of the most rigorous credentials in the natural health field. ICONIC Board does not replace or replicate that — it adds professional practice recognition in dimensions that ND licensing alone does not specifically document: your holistic practice philosophy, ethics framework, breadth of continuing education, and professional practice standards as a holistic health practitioner.
For traditional naturopaths practicing in unlicensed states, ICONIC Board is especially valuable. With no state license available and government recognition absent, ICONIC Board establishes that you operate to recognized professional standards — providing clients and referral networks with a trustworthy professional credential.
Explore ICONIC CredentialsIn states without ND licensing, ICONIC Board provides professional standing that state government does not. It requires you to document your scope of practice, ethics commitments, and continuing education — the same professional disciplines that licensing requirements would otherwise mandate. For clients in unlicensed states who want to work with a naturopathic practitioner, an ICONIC Board credential signals genuine professional commitment.
