Traditional Frameworks vs Biomedical Explanations
How to tell apart what traditional Chinese medicine says, a proposed mechanism, a physiological finding and a clinical result, using meridians and the research on TCM as examples.

Four kinds of statement
When you read about traditional Chinese medicine (TCM), a claim usually falls into one of four levels. Mixing them up is the most common source of confusion.
| Level | What it is | Example | Strength |
|---|---|---|---|
| Traditional explanation | What the tradition says | Illness is an imbalance of qi [1] | A belief within a framework, not tested as stated |
| Proposed mechanism | A hypothesis about how something might work | Points and meridians may be special conduits for electrical signals [2] | Needs testing |
| Physiological finding | Something measured in the body | Some studies found lower electrical resistance at points, but they were small, poor in quality and confounded [2] | Inconclusive |
| Clinical outcome | Whether people do better in trials | Acupuncture and tai chi may help certain pain conditions and quality of life [3] | Depends on the practice and the use |
Why the levels matter
A practice can have a clinical benefit even if its traditional explanation is not a biomedical mechanism, and a practice can have a persuasive-sounding mechanism and still fail in trials. Judge a treatment by its outcomes in good trials, and treat the explanation as the tradition's story or a hypothesis. NCCIH, for example, says studies suggest acupuncture stimulates natural painkillers and affects brain areas involved in processing pain, but that some trials suggest real and sham acupuncture are equally effective, indicating a placebo effect. [3]What the evidence for TCM as a whole looks like
A 2022 overview of 104 Cochrane reviews on TCM covered herbal medicine (70 reviews), acupuncture (28), TCM exercises (4) and moxibustion (2). Only 5 reached overall positive conclusions, 42 concluded the evidence was insufficient and 54 failed to draw firm conclusions. The authors concluded that evidence of effectiveness remains largely inconclusive and called for higher-quality trials. [4] That is a statement about the quality of the research, not proof that nothing works.Traditional medicine in official health systems
The World Health Organization's ICD-11 includes an optional supplementary chapter, "Traditional medicine conditions", so traditional medicine encounters can be counted and compared with mainstream medicine. [5] This is a classification tool. It does not by itself establish that a treatment works.Reading claims you meet
- "Balances your qi" is a traditional explanation, not a result.
- "Studies show" needs a named study: what treatment, for whom, compared with what (sham, usual care, nothing), and what outcome.
- Many TCM practices cannot be fully blinded, so expectation effects can inflate results.
- Safety is a separate question from effectiveness. See Chinese Herbal Products: Quality, Contamination and Medicine Interactions.
For the concepts themselves see Traditional Concepts. For results by use see TCM Evidence by Use. A general guide is How to Evaluate a Therapy Claim. Do not use any explanation, traditional or biomedical, as a reason to delay care for serious symptoms. [3]
Frequently asked questions
Is TCM scientific?
Specific TCM practices can be tested in trials, and many have been. The traditional framework itself is a separate matter and is not presented here as biomedical science. [3][4]
Does it matter if the explanation is wrong?
For deciding whether to try a treatment, outcomes in good trials matter more. Safety also matters regardless of the explanation. [3]
Do meridians have a biomedical basis?
A systematic review found the evidence did not conclusively support that they are electrically distinguishable. [2]
Does ICD-11 mean TCM is proven?
No. The supplementary chapter is optional and is for counting and studying traditional medicine. [5]
