Professional Chinese medicine is an evidence-based medicine.

It is grounded in the theories and accumulated experiences of

a hundred generations of physicians and billions of patient

interactions. This massive foundation of evidence is the reason

Chinese medicine can be so effective for so many various

ailments with so little negative side effects. This base of clinical

experience is unparalleled in both its size and the claims it is

able to support.


Modern science and the contemporary medical system based on that approach to rational investigation are slowly realizing, demonstrating through clinical research, the effectiveness of Chinese medicine. Current scientific theories, methods, and techniques are new and, thus, it will take time for them to fully appreciate the scope and power of Chinese medicine. However, there is already many, high quality studies available reflecting the effectiveness of Chinese medicine, mostly through the modality of acupuncture.



A few words of advice before your search...

Bear in mind, due to the nature of contemporary scientific

research, studies are typically conducted on very specific

topics. For example, the question "Does acupuncture work" 

cannot be investigated because it is too general. Similarly

acupuncture for pain is too broad a topic for which to locate

specific clinical trials (though there may be articles addressing

such general topics). Instead, try looking for "knee pain" or

"back pain".


Also keep in mind, modern research is based on very different fundamental principles than Chinese medicine. For example, Chinese medicine has always focused on the unique aspects of a patient, individualizing treatments for their specific disease presentation. Compare this to modern medicine where diseases are the topic of discussion and research; patients, themselves, exist in the background of the clinical picture.


Also, modern research makes great effort to reduce a treatment's effect to very specific causes. For instance, it strives to eliminate as many influences on a patient's condition, except for the therapeutic intervention, as possible. This allows such research to make a stronger claim about what, exactly, caused the outcome. That is, where there were few other influences                                                               on the patient, the claim that the treatment "caused"                                                                   the outcome is much stronger. Though eminently                                                                         logical, this is a very poor model of an actual clinical                                                                     encounter. In medicine as it's practiced out in the real                                                                 world there are always numerous, truly an unknowable                                                               amount of influences on any given patient during                                                                         therapy. Importantly, the treatment itself consists of                                                                     many different aspects, each contributing to the end                                                                   treatment outcome. Chinese medicine does not try to                                                                   rigorously isolate and identify narrow "causes" of effect, e.g., which twist of which acupuncture needle caused what percentage of change in the patient's fever irrespective of other aspects of the patient's condition or the therapy overall. Instead it always looks at the larger picture to learn what worked and what didn't. Over countless treatments occurring over hundreds of years, Chinese medicine has been able to identify what herbs and what acupuncture points tend to do what in the clinic. One, thus, gets limited information about what Chinese medicine can do for them from any given study. Their treatment will never be exactly what was done in the study because Chinese medicine always treats you and your condition as unique. Modern research, thus, in its search for exactness, compromises its usefullness for actual patient interactions. Nonetheless, the research below is still of interest.


Lastly, there is a widely held assumption that Western medicine is backed by clinical research, the very same research which fails to support Chinese medicine. In seeking evidence of effectiveness of acupuncture, for example, one is often acting on the assumption that such evidence exists for biomedicine and that acupuncure, too, needs to live up to this standard for medical care. The rigors of science require we challenge this assumption. The highly esteemed British Medical Journal did just this with the following results






 






      "...what can Clinical Evidence tell us about the state of our current knowledge? What             proportion of commonly used treatments are supported by good evidence, what                     proportion should not be used or used only with caution, and how big are the gaps in our         knowledge? Of around 2500 treatments covered 13% are rated as beneficial, 23% likely         to be beneficial, 8% as trade off between benefits and harms, 6% unlikely to be                       beneficial, 4% likely to be ineffective or harmful, and 46%, the largest proportion, as                 unknown effectiveness."

Modern Clinical Research into Acupuncture and Chinese Medicine

Note - There are very few individual studies listed below. Instead, most of the research below are systematic reviews and meta-analyses, the highest level of modern clinical research. 


For ease of finding research on specific ailments, it is recommended you use your browser's search function, for example, pressing "CTRL + F" and entering the ailment which you are curious about. 



High Quality Reviews of the Acupuncture Treatment of Pain
      A March, 2011 overview aimed at evaluating and summarizing transparent and rigorous Cochrane reviews of acupuncture in the treatment of pain. All the reviews were of high methodological quality and eight of them concluded that acupuncture is effective for migraines, neck disorders, tension-type headaches, and peripheral joint osteoarthritis.

Acupuncture Gets an “A” for Treating Chronic Low Back Pain
      In the June 15th, 2009, issue of American Family Physician, acupuncture was given an evidence rating of “A”, the same rating given to analgesics, such as acetaminophen and Ultram, and non-steroidal anti-inflammatory medications (NSAIDs) – That’s the same strength of evidence, but without all the potential damage to the kidney and gastrointestinal systems!

Osteoarthritis, low back pain, and elbow pain
      An overview of systematic reviews (SRs being the

highest level of modern clinical evidence) coming out

of the journal Rheumatology concluded that there is

“sufficiently sound” evidence to “warrant positive

recommendations” of acupuncture for osteoarthritis,

low back pain, and elbow pain.

Acupuncture Research – Knee Pain
      This study, published in 2007, was aimed at evaluating the effects of acupuncture on pain and function in patients with chronic knee pain. It included a systematic review and meta-analysis of randomized controlled trials (RCTs).  Studies were chosen that randomly assigned patients to either acupuncture, sham acupuncture, usual care, or an active intervention.
Acupuncture was “superior” to sham acupuncture for both pain and function, in both short-term and long-term follow-up. Acupuncture was also “significantly superior” to usual care.
There were insufficient studies to compare acupuncture with other active interventions.

In the following systematic review of acupuncture for insomnia, where several randomized controlled trials (RCTs) were evaluated for their quality, and those of sufficient quality reviewed:

  • acupuncture was found to be beneficial,
  • acupuncture was superior to medications, regarding “number of patients with total sleep duration increased >3 hours”, and
  • acupuncture with medications was better than medications alone, for total sleep duration.


Additionally, there were no serious adverse effects with the acupuncture treatments.

Forty-six randomized trials were included (3,811 patients). The methodology, as far as randomization, blinding, and “intention-to-treat analysis”, was deemed “generally fair”.

This literature review of clinical trials (randomized, non-randomized, and observational studies) on acupuncture treatment of polycystic ovarian syndrome (PCOS) was conducted by the Faculty of Medicine, South Western Sydney Clinical School, University of New South Wales, in Australia. It concluded that acupuncture is “safe and effective” in the treatment of PCOS and posited, as possible mechanisms of acupuncture treatment:

  • increased blood flow to the ovaries,
  • reduction of ovarian volume and number of ovarian cysts,
  • control of hyperglycaemia through increased insulin sensitivity and decreased blood glucose and insulin levels,
  • reduction of cortisol levels, and
  • assisting in weight loss and anorexia
