TCM-Style Supplements vs Traditional Formulas: Not the Same Thing

Back to Traditional Chinese Medicine (TCM)Same names, different products
A practitioner's herbal formula is written for a person after an assessment, and a practitioner may change it over time. A bottle on a shelf is a fixed product made for many buyers. Even when a bottle uses a classical formula name, it can differ from the traditional version in which herbs are included, how they are prepared and which parts of the plant are used. Product forms are covered on decoctions, granules, teapills, tinctures and patches, and how formulas are built on how a Chinese herbal formula is built.Comparison
| Practitioner-written formula | Shelf supplement or patent product | |
|---|---|---|
| Who chooses it | A practitioner, after assessment | The buyer, from a label |
| Fixed or adjusted? | Often adjusted over visits | Fixed recipe |
| US legal category | Depends on use; a botanical product intended to treat disease would generally be regulated as a drug, one taken by mouth and labeled as a supplement generally as a dietary supplement [1] | Mostly dietary supplement |
| Claims allowed on label | Not applicable to a compounded prescription | US supplement labels cannot claim to diagnose, treat, cure, mitigate or prevent disease; structure/function claims need a disclaimer [2] |
| FDA review before sale | Not as a drug | Not authorized to review supplements for safety and effectiveness before marketing, with an exception for some new ingredients [2] |
| Quality checks | Depend on supplier | Companies are responsible for safety and truthful labels [2] |
What testing has found
NCCIH says Chinese herbal products have been found contaminated with undeclared plant or animal material, drugs (including warfarin and diclofenac), heavy metals (arsenic, lead and cadmium), pesticides and sulfites, or with the wrong herb, some of which has caused organ damage. [4] Chinese regulators approved 184 supplementary testing methods for TCMs between 2003 and 2017 to detect adulteration, and found undeclared drugs, substituted components and foreign material; diabetes, sleep, sexual dysfunction, pain and rheumatism products were most vulnerable. [5] In Hong Kong, a laboratory found undeclared drugs in 487 proprietary Chinese medicines and health products over ten years. [6]Aristolochic acid is a documented example. An FDA import alert says several outbreaks of kidney failure were attributed to Chinese herbal medicines containing it, partly because similar traditional Chinese names were confused, and that a product with a small amount could be used for years before serious, irreversible kidney damage appeared. [7]
Evidence is for a specific product
Research on a formula tested in a trial applies to that formulation, not to every product with the name. NCCIH describes the evidence on Chinese herbal products for a range of conditions as mixed. [4]Practical questions to ask
- What exactly is in this product, in which amounts, and who tested it?
- Is it safe with my medicines, liver, kidneys and pregnancy status? Ask a pharmacist.
- Is any ingredient on safety lists such as Chinese herbs with known safety concerns?

Frequently asked questions
Is a Chinese herbal supplement the same as a prescription formula from a practitioner?
No. One is a fixed shelf product, the other is chosen for an individual, and they are regulated differently.
Does the FDA approve herbal supplements?
Not before they are sold. The FDA can act after problems appear. [2]
Does "traditional" on a label mean tested?
No. In the EU, "traditional use" explicitly means based on long-standing use rather than clinical studies. [3]
Can supplements contain hidden drugs?
Yes. Hidden drugs have been documented in products from China and Hong Kong, and the FDA has found undeclared drugs in US-sold supplements. [6][8]
Where do I report a problem?

Regulation in the US and Europe
In the US, the FDA can act against adulterated or misbranded supplements only after they are on the market. [2] In the European Union, herbal medicines assessed by the European Medicines Agency committee can be authorized under a "traditional use" route, which means use is based on long-standing use and not on clinical study results; food supplements and other product types are outside that route. [3] For ginseng root, the committee limited its traditional-use conclusions to fatigue and weakness. [3] More jurisdictions are on how Chinese herbal products are regulated.
