Naturopathy is a real, regulated profession in about two dozen US jurisdictions, but whether it is "legit" depends on who is practicing and which treatment you mean. Licensed naturopathic doctors (NDs) train at accredited schools and pass national board exams. Research on naturopathic care as a whole is limited: the studies that exist mostly report benefits for chronic conditions, but many are small or poorly controlled. Some treatments common in naturopathic practice, such as homeopathy, colon cleansing and chelation, have no good evidence behind them.
Two kinds of naturopath
The first question is who is practicing. The National Center for Complementary and Integrative Health (NCCIH) separates two groups:
- Licensed naturopathic doctors complete a four-year doctoral program accredited by the Council on Naturopathic Medical Education (CNME), pass the national NPLEX board exams, and hold a state license where one exists.
- Traditional naturopaths train in programs that are not accredited and are not eligible for a license.
Accredited ND programs must run at least four academic years and 4,100 clock hours, including at least 1,200 hours of clinical training (CNME Handbook of Accreditation, 2025). There is no equivalent standard for traditional naturopaths. To see how ND training compares with a medical degree, read whether a naturopathic doctor is a real doctor.
What the research on naturopathic care shows
The main reviews look at naturopathic care as it is delivered in practice, rather than at single remedies. Here is what they found.
| Source | What it looked at | What it found | Limits |
|---|---|---|---|
| Myers and Vigar, 2019 | 33 published studies, 9,859 participants, mostly chronic conditions | Authors concluded naturopathic care was effective for cardiovascular disease, musculoskeletal pain, type 2 diabetes, PCOS, depression, anxiety and complex chronic conditions | Included case series of as few as five patients, which weakens the conclusion |
| Calabrese and colleagues, 2012 | A systematic review in progress that had identified 12 studies of whole-practice naturopathic care, six of them randomized trials | Said the findings showed effectiveness and cost savings that merit further investigation | A conference abstract, not a full peer-reviewed paper |
| Oberg and colleagues, 2015 | The full published version of that review, on select chronic conditions | Reported benefit in its included studies and no evidence of harm | Authors noted the limits of observational designs |
| Merck Manual | Overview for the public | Few well-designed studies of naturopathy exist | Summary, not a new review |
| NCCIH | Federal overview | Does not rate whether naturopathy as a whole works | No verdict either way |
The fair reading is that the evidence is thin rather than clearly negative. The studies mostly report benefits, but many are too small or too loosely designed to show that naturopathic care caused them.
Where the evidence falls short
Criticism is strongest for specific treatments:
- Homeopathy, chelation and colon cleansing. A 2011 analysis by Caulfield and Rachul reviewed 53 naturopathic clinic websites in Alberta and British Columbia. The commonly advertised treatments it examined, including these three, had no evidence beyond placebo. The study looked at what clinics advertised, not at patient outcomes.
- "Detox" and colon cleanses. NCCIH says the evidence for detoxes and cleanses is limited and that colon cleansing can cause serious side effects. A 2009 systematic review found no rigorous controlled trials supporting colon cleansing for general health and described adverse effects in case reports. Its authors said the practice cannot be recommended.
- Vaccines. The Merck Manual notes that some naturopaths discourage childhood vaccination.
The claim made by some sites, including earlier versions of this one, that naturopathic medicine is simply "better" than conventional medicine is not supported. None of the reviews above makes that comparison.
What about specific conditions?
No study we found rates naturopathic care as a whole for any single condition. What exists is evidence on individual approaches that naturopaths often use. The table summarizes it, from federal summaries, guidelines and reviews checked in October 2026. Each condition page has the details.
| Condition | What the evidence shows for common approaches | See a medical doctor first if |
|---|---|---|
| Fatigue | Supplements: not supported; the ginseng evidence in one review came from a lab study, not a clinical trial. For cancer-related fatigue, a 2023 editorial in Asian Biomedicine says complementary and non-drug approaches may be justified (editorial). It is about people with cancer, not unexplained fatigue. | Tiredness comes with confusion, dizziness or blurred vision, or with fever, night sweats or weight loss you didn't try for. |
| PCOS | Inositol: the 2023 international PCOS guideline says it could be considered for possible metabolic benefits, with limited benefit for ovulation, excess hair or weight, and it calls inositol experimental as a fertility treatment (2023 guideline). Acupuncture: trials are weak. | Not urgent. Doctors usually diagnose PCOS when two of three features are present (androgen excess, irregular ovulation, or polycystic ovaries on ultrasound), after other causes are excluded (AAFP, 2023). The CDC lists type 2 diabetes, high blood pressure, heart disease and stroke among PCOS-related risks, and advises people with PCOS to ask about diabetes testing. |
| Menopause symptoms | Herbal products: not supported (British Menopause Society, 2026). Acupuncture for hot flashes: better than no treatment, but no better than sham (NCCIH). | Bleeding lasts more than 7 days or soaks a pad or tampon every hour for several hours (ACOG). |
| IBS and digestive symptoms | Enteric-coated peppermint oil may modestly help in the short term. The American College of Gastroenterology's 2021 IBS guideline suggests against probiotics for overall IBS symptoms, based on very low-quality evidence (ACG, 2021). Gut-directed hypnotherapy is recommended, with low-quality evidence. Acupuncture: no better than sham (NCCIH). | Rectal bleeding, black stools, or weight loss you didn't try for. |
| Anxiety | Kava: short-term benefit, with an FDA liver-injury warning. Chamomile and lavender: preliminary. CBT is the better long-term option for generalized anxiety (NCCIH). | Thoughts of self-harm: call or text 988, the Suicide and Crisis Lifeline, or call 911 if someone is in immediate danger. |
| Migraine | Butterbur reduces attacks but contains liver-toxic compounds, and the American Academy of Neurology retired the guideline that had recommended it in 2015. Magnesium, riboflavin and CoQ10: mixed. Acupuncture: a small benefit over sham (NCCIH). | A sudden, severe headache that peaks within seconds or minutes, or a new headache after age 50 (AAFP, 2022). |
| Chronic low back pain | Yoga, tai chi and mindfulness-based stress reduction are guideline options (ACP, 2017). Acupuncture and spinal manipulation: mixed, low-quality evidence. | New bladder or bowel control problems, numbness in the groin or buttocks, or leg weakness that is getting worse. |
"Mixed" means some benefit was reported, but the studies are small, short or inconsistent. A practitioner who recommends one of these approaches should be able to tell you what evidence supports it for your situation.
Is naturopathy dangerous?
The honest answer is that the risk hasn't been well measured. We found no systematic review of harms from naturopathic care in PubMed (searched October 2026). A 2022 study looked at how adverse events are reported in naturopathic clinics, which is a different question. The specific harms on record come from particular treatments, such as the colon-cleansing side effects above. NCCIH gives no blanket safety warning about naturopathy.
The American Medical Association has opposed bills to let NDs prescribe more drugs. In 2024 testimony, it argued that NDs lack residency training and broad clinical exposure. The fuller debate is in why many doctors are critical of naturopaths.
NCCIH's advice applies to everyone who uses complementary care: tell all your health care providers what you are taking and doing.
Why people see naturopaths anyway
Two features of naturopathic care are relevant here:
- Longer visits. One vendor's pricing benchmark puts a first naturopathic visit at 60 to 90 minutes.
- A stated focus on the whole person and on causes. The profession lists six principles, including "treat the whole person," "identify and treat the causes" and prevention (AANMC). These are professional principles, not research findings.
Neither point shows that a given treatment works. They explain why some people try naturopathy alongside, not instead of, medical care.
Is naturopathy legit where you live?
Legal status varies a great deal by state:
| Status | Where | What it means for you |
|---|---|---|
| Licensed or registered | 23 states, plus D.C. and Puerto Rico | You can verify an ND's license with the state board |
| Banned | Florida, South Carolina, Tennessee | Practicing naturopathy is illegal; in Florida it is a felony without a license |
| Unregulated | 24 states, including New York | No ND license exists to check, so verify training directly |
Our count of 23 states comes from state statutes, as summarized by the Wyoming Legislative Service Office (2025) and Connecticut's Office of Legislative Research (2023). The AMA (2024) says at least 24 states and D.C. license or regulate naturopathic doctors, so check your state board.
In New York, the sponsor memo for licensing bill S8714 notes that "anyone may lay claim to the title." The bill was referred to committee in January 2026. See which states license naturopathic doctors and which states let them prescribe.
How to try naturopathy sensibly
- Choose a licensed ND. Check for a CNME-accredited degree and NPLEX. In New York, where no ND license exists, check what other license the person holds with the NYSED license verification search.
- Keep your medical doctor. Use naturopathic care alongside medical care, not instead of it.
- Ask about the evidence. For each recommendation, ask what research supports it and what it costs.
- Skip the weakest treatments. Be cautious about colon cleanses, "detox" programs and homeopathic products.
- Share everything. Give your doctor a list of every supplement and treatment, and ask the ND to share notes.

When to see a medical doctor
- Emergencies, and any new, severe or fast-worsening symptoms.
- Symptoms that haven't improved with naturopathic care.
- Before stopping or changing a prescribed medication, screening or vaccine.
- Any condition that needs prescription drugs, surgery or hospital care.
