Common Myths and Misunderstandings About TCM

At a glance

1. "TCM is one unchanging ancient system"

   Partly true

   It evolved over a long time and its formulas were built up and recombined

2. "It is all placebo"

   Mixed

   Acupuncture beat sham for chronic pain in a large analysis, with a small gap; herbs are mixed

3. "It works for everything"

   Not supported

   Good results are limited to some approaches and conditions

4. "Natural herbs cannot hurt you"

   Evidence of harm

   Contamination, wrong herbs and aristolochic acid have caused harm

5. "Chinese research proves it"

   Mixed

   Reviews flag possible publication bias and uneven quality

6. "It has produced nothing useful"

   Not supported

   Artemisinin led to a Nobel Prize

7. "It can replace cancer treatment"

   Not supported

   Used for symptom relief alongside care, not as a replacement

"TCM is one ancient, unchanging system"

NCCIH says TCM has evolved over thousands of years. [1] A 2024 analysis of 59,063 formulas recorded over about two thousand years found that formula building resembled recombination, and that the core components stayed quite stable. [2] Modern TCM is also not a single national practice: see the history of TCM and TCM outside China.

"It is all placebo" and "it works for everything"

For acupuncture, NCCIH says some trials suggest real and sham acupuncture are equally effective, indicating a placebo effect, while other results suggest real acupuncture may help ease some chronic pain types. [1] An individual-patient analysis of 39 trials (20,827 patients) found acupuncture superior to sham and to no acupuncture for chronic musculoskeletal pain, osteoarthritis, headache and shoulder pain, with a difference of about 0.2 standard deviations against sham and 0.5 against no acupuncture. [3] That is a real but small specific effect. NCCIH describes the evidence for Chinese herbal products as mixed, with many poor-quality studies and no firm conclusions. [1] Details: TCM evidence by use.

"Natural herbs cannot hurt you"

NCCIH reports Chinese herbal products contaminated with undeclared drugs, heavy metals, pesticides or wrong herbs, some causing organ damage. [1] The FDA says outbreaks of renal failure were attributed to Chinese herbal medicines later shown to contain aristolochic acid, which it calls a potent carcinogen and nephrotoxin, and notes that the plant was sometimes mis-identified or confused because names were misinterpreted. [4] See aristolochic acid and kidney injury and natural and traditional do not mean safe.

"Chinese research proves it"

A 1998 review found that all acupuncture trials originating in China, Japan, Hong Kong and Taiwan were positive, and 99% of non-acupuncture trials published in China were, against 75% in England, and said publication bias was a possible explanation. [5] More recently, an appraisal of 64 COVID-19 trials of TCM found those published in Chinese were of significantly worse quality than those in English. [6] That does not mean every Chinese trial is wrong. It means trials should be read individually; see how to read a TCM study.

"It has produced nothing useful"

The 2015 Nobel Prize in Physiology or Medicine recognized Tu Youyou, who after studies of traditional herbal medicines focused on sweet wormwood and extracted artemisinin, which inhibits the malaria parasite. [7] This is a purified drug found through a traditional text, and it says nothing either way about other herbs; our editorial view is that each product needs its own testing. See artemisinin and Tu Youyou.

"It can replace cancer treatment"

NCCIH says not to use TCM to replace or delay conventional care. [1] The National Cancer Institute defines "alternative" medicine as used instead of standard treatment, and notes less research exists on most such approaches. [8] The guideline-supported uses we found are symptom relief alongside care; see integrative Chinese medicine.

A fair summary

Some TCM approaches have decent evidence for particular problems, some herbs have real risks, and many claims have not been tested well. Traditional ideas such as qi are cultural and medical frameworks, not measured biological facts; see traditional frameworks vs biomedical explanations.
