Naturopathic and Integrative Care Safety Quick Reference

A one-page safety summary for naturopathic and integrative care: when to call 911 first, who should check with a clinician, and where to find each detailed safety page.

Content last updated . This page has not been medically reviewed.

This page is a quick safety summary, not medical advice. Alternative and integrative approaches are never a reason to delay urgent or standard medical care. Read the urgent section first.

Call for help first

  • Possible heart attack. Call 911 or your local emergency number right away. Do not try to drive yourself to the hospital.[1] Chest pain is the most common symptom.[1]
  • Possible stroke. Call 911 or your local emergency number right away at the first signs.[2] MedlinePlus's quick checks: FACE (does one side droop when the person smiles?), ARMS (does one arm drift down when both are raised?), SPEECH (are words slurred when repeating a simple sentence?).[2]
  • Severe allergic reaction (anaphylaxis). It is an emergency; call 911 or your local emergency number immediately.[3] Signs include swelling of the face, eyes or tongue and difficulty breathing or wheezing.[3] An epinephrine injector should be used immediately if one is available.[3]
  • Poisoning or overdose, including from a supplement, herb, essential oil or cleanse product. In the US, call Poison Help at 1-800-222-1222, or 911 in an emergency. See Poisoning: What to Do First, Poison Help by Country and Emergencies and Poisoning During Natural Treatments.
  • Thoughts of suicide or a mental health crisis. In the US, call, text or chat 988. The Lifeline is available 24/7 and conversations are free and confidential.[4]
  • Pregnancy warning signs, or a sick infant or child. Contact a doctor or emergency services right away rather than trying a natural treatment first; see Pregnancy and Postpartum and Children and Infants.

Seven safety rules in one place

SituationWhat the sources sayMore
Any health problemDo not use a product or practice that has not been proven effective to postpone seeing your health care provider.[5]
CancerNo complementary approach has been shown to prevent or cure cancer, and delayed treatment reduces the likelihood of remission or cure.[6] In an observational study of 281 patients with nonmetastatic cancers who chose alternative medicine alone, use was associated with greater risk of death than conventional treatment.[7]
VaccinesGet information from health authorities. WHO advises talking with your health care provider about which vaccinations you need.[8]
Medicines and surgerySupplements may interact with medicines, may increase bleeding risk or affect response to anesthesia, and you should tell providers well before an operation.[9] Do not stop or change a prescribed medicine on your own; ask the prescriber.
Detox, fasting and cleansesSome programs can be unsafe and falsely advertised; fasting can cause headaches, fainting, weakness and dehydration.[10]
TestsNo test is perfect, and at-home tests should never replace testing your provider orders.[11]
Choosing a practitionerFind out about education, training, licensing and certifications; credentials vary tremendously by state and discipline.[12] Licenses do not guarantee safe, effective treatment.[13]

Check with a clinician before starting

Talk with a doctor, pharmacist or other licensed clinician first if any of these apply. The list is general and not exhaustive.

  • Pregnant, breastfeeding, trying to conceive, or giving a child a supplement. NCCIH says many dietary supplements have not been tested in pregnant women, nursing mothers or children.[9]
  • Cancer. NCCIH says to consult your health care providers before using any complementary health approach, and that some herbs may make chemotherapy less effective.[6]
  • Kidney or liver disease. NCCIH notes colon cleansing harms are more likely in people with kidney disease,[10] and that kava supplements can cause liver disease.[9]
  • Several medicines, or blood thinners. NCCIH notes St. John's wort makes many medications less effective, and the FDA has found anticoagulants such as warfarin hidden in products sold as supplements.[9]
  • Before surgery. Certain supplements may increase bleeding risk or affect response to anesthesia.[9]
  • History of an eating disorder. Fasting and cleanse programs deserve a clinician's input first; the NHS lists taking laxatives after eating among eating disorder symptoms.[14]
  • Older adults. See Older Adults for medicine and supplement load.

Frequently asked questions

What should I do if I have a bad reaction to a supplement or treatment?

NCCIH says if you have side effects from a supplement, stop taking it and contact your health care provider.[9] For severe symptoms such as trouble breathing or swelling of the face or tongue, call 911.[3]

Is "natural" the same as safe?

No. NCCIH says "natural" does not necessarily mean "safe."[5] Supplements can interact with medicines and some can cause serious harm, such as liver disease linked to kava.[9]

Can an alternative treatment be used instead of cancer treatment?

NCCIH advises against using unproven products or practices to replace or delay medical treatment for cancer.[6] See Naturopathic and Integrative Care in Cancer.

Do I need to tell my doctor about the natural products I use?

Yes. NCCIH advises telling all your providers, complementary and conventional, about all the health approaches you use, to support coordinated and safe care.[5]

Who can I contact about a problem with a supplement?

The FDA has authority to act against adulterated or misbranded supplements after they reach the market.[15] See Side Effects, Allergic Reactions and Reporting.
