Back to Traditional Chinese MedicineWhy this page exists
Most Chinese medicine practitioners work honestly. But the field includes unregulated products and, in many places, unregulated practice, so it helps to know the signs of trouble. This page is information only. It does not rank or name any practitioner, clinic or seller.Red flags about claims
| Warning sign | Why it matters | Source |
|---|---|---|
| Promises of a cure, or "too good to be true" results | Health fraud products claim to prevent, treat or cure disease but are not proven safe and effective [1]; MedlinePlus says to beware of promises of cures [2] | FDA, MedlinePlus |
| A product said to work like a prescription drug | FDA lists claims of being an alternative to approved drugs as a warning sign [3] | FDA |
| Very fast results promised | FDA lists rapid-effect claims as a warning sign [3] | FDA |
| Label mainly in a foreign language, or sold in unusual places such as gas stations or online marketplaces | FDA lists both as warning signs [3] | FDA |
| "Natural" or "traditional" used as proof of safety | There is no official definition of "natural" in medicine and it does not always mean safe [4] | NCCIH |
Red flags about advice
- Telling you to stop or skip your medicine. Never stop a prescribed medicine without talking to your doctor. [5]
- Discouraging conventional care. NCCIH says not to use TCM to replace or delay conventional care. [6] Health fraud can delay proper diagnosis and treatment. [1]
- Not asking what you take. Herbs can raise or lower the effect of medicines, and for many there is little interaction information. [7]
- Refusing to work with your doctor. NCCIH advises choosing a practitioner willing to work with your other providers. [8]
- One cure for everything, or a diagnosis made from a quiz, photo or phone call alone. For why diagnosis methods vary, see tongue diagnosis and online quizzes.
Red flags about products
- Sold without an ingredient list, or with "secret formula" claims. Some Chinese herbal products have been found to contain undeclared plant or animal material, drugs such as warfarin and diclofenac, heavy metals, or the wrong herb. [6]
- Supplements marketed for weight loss, sexual health or athletic performance, which NCCIH says are the categories where hidden prescription drugs have been found. [9]
- No sign anyone checks quality. In the US, supplement marketers do not have to prove to FDA that a product is safe or works before sale [9], and FDA can act only after a product is on the market. [10]
- Sold online as unlicensed herbal medicine. The NHS says not to buy unlicensed herbal medicines online. [5]
See undeclared drugs in patent medicines and heavy metals in Chinese medicines.
Red flags about credentials
Credentials alone do not prove quality: NCCIH says being licensed or certified is not always a guarantee of being qualified. [11] But a practitioner who will not tell you their training, license or certification is a warning sign. In England, herbal medicine practitioners do not need to be registered by law, so the NHS advises choosing one registered with a professional body accredited by the Professional Standards Authority. [5] In the United States, requirements vary tremendously from state to state. [8] See how to choose a practitioner.What to do
- Stop the product if you feel unwell and get medical care. See warning signs after Chinese herbs.
- Tell your doctor or pharmacist what you took.
- In the US, report safety concerns about a supplement through the Health and Human Services Safety Reporting Portal. [10]
- Keep the packaging.
For emergencies in the US call 911; Poison Help is 1-800-222-1222.
Frequently asked questions
Is a very long list of conditions treated a red flag?
Claims to prevent, treat or cure many diseases are what FDA describes in health fraud products. [1] Ask what evidence exists for each use.
Does a license mean the practitioner is good?
Not always. NCCIH says licensed or certified does not guarantee someone is qualified. [11]
Can I tell if an herbal product is contaminated?
Not by looking. Contaminants have included undeclared drugs and heavy metals. [6] Ask a pharmacist.
Is "traditional" the same as safe?
No. NCCIH says natural does not always mean safe. [4]
Where do I report a problem?
In the US, through the HHS Safety Reporting Portal for supplements. [10] See reporting problems with Chinese herbs.
