CHINESE MEDICINE

Acupuncture, Qigong, and Chinese Medicine
Stephen Barrett, M.D.
Chinese medicine, often called Oriental medicine or traditional Chinese medicine (TCM),
encompasses a vast array of folk medical practices based on mysticism. It holds that the
body's vital energy (chi or qi) circulates through 14 channels, called meridians, that
have branches connected to bodily organs and functions. Illness is attributed to
imbalance or interruption of chi.. Ancient practices such as acupuncture and Qigong are
claimed to restore balance.
Traditional acupuncture, as now practiced, involves the insertion of stainless steel
needles into various body areas. A
low-frequency current may be applied to the needles to produce greater stimulation. Other
procedures used separately or together with acupuncture include: moxibustion (burning of
floss or herbs applied to the skin); injection of sterile water,procaine, morphine,
vitamins, or homeopathic solutions through the inserted needles; applications of laser
beams (laserpuncture); placement of needles in the external ear (auriculotherapy); and
acupressure (use of manual pressure).
Treatment is applied to acupuncture points, which are said to be located throughout the
body. Originally there were 365 such points, corresponding to the days of the year, but
the number identified by proponents during the past 2,000 years has increased gradually
to about 2,000 [1]. Some practitioners place needles at or near the site of disease,
whereas others select points on the basis of symptoms. In traditional acupuncture, a
combination of points is usually used.
Qigong is also claimed to influence the flow of vital energy. Internal Qigong involves
deep breathing, concentration, and relaxation techniques used by individuals for
themselves. External Qigong is performed by Qigong masters who claim to cure a wide
variety of diseases with energy released from their fingertips. However, scientific
investigators of Qigong masters in China have found no evidence of paranormal powers and
some evidence of deception. They found, for example, that a patient lying on a table
about eight feet from a Qigong master moved rhythmically or thrashed about as the master
moved his hands.
But when she was placed so that she could no longer see him, her movements were unrelated
to his [2]. Falun gong, which China recently banned, is a Qigong varient claimed to be a
powerful mechanism for healing, stress relief and health improvements.
Most acupuncturists espouse the traditional Chinese view of health and disease and
consider acupuncture, herbal medicine, and related practices to be valid approaches to
the full gamut of disease. Others reject the traditional approach and merely claim that
acupuncture offers a simple way to achieve pain relief. The diagnostic process used by
TCM practitioners may include questioning (medical history, lifestyle), observations
(skin, tongue, color), listening (breathing sounds), and pulse-taking. Six pulse aspects
said to correlate with body organs or functions are checked on each wrist to determine
which meridians are deficient in chi. (Medical science recognizes only one pulse,
corresponding to the heartbeat, which can be felt in the wrist, neck, feet, and various
other places.) Some acupuncturists state that the electrical properties of the body may
become imbalanced weeks or even months before symptoms occur. These practitioners claim
that acupuncture can be used to treat conditions when the patient just doesn't feel
right, even though no disease is apparent.
TCM (as well as the folk medical practices of various other Asian countries) is a threat
to certain animal species. For example, black bears -- valued for their gall bladders --
have been hunted nearly to extinction in Asia, and poaching of black bears is a growing
problem in North America.
Dubious Claims
The conditions claimed to respond to acupuncture include chronic pain (neck and back
pain, migraine headaches), acute injury-related pain (strains, muscle and ligament
tears), gastrointestinal problems (indigestion, ulcers, constipation, diarrhea),
cardiovascular conditions (high and low blood pressure), genitourinary problems
(menstrual irregularity, frigidity, impotence), muscle and nerve conditions (paralysis,
deafness), and behavioral problems (overeating, drug dependence, smoking). However, the
evidence supporting these claims consists mostly of practitioners' observations and
poorly designed studies. A controlled study found that electroacupuncture of the ear was
no more effective than placebo stimulation (light touching) against chronic pain [3]. In
1990, three Dutch epidemiologists analyzed 51 controlled studies of acupuncture for
chronic pain and concluded that the quality of even the better studies proved to be
mediocre. . . . The efficacy of acupuncture in the treatment of chronic pain remains
doubtful. [4] They also examined reports of acupuncture used to treat addictions to
cigarettes, heroin,
and alcohol, and concluded that claims that acupuncture is effective as a therapy for
these conditions are not supported by sound clinical research [5].
Acupuncture anesthesia is not used for surgery in the Orient to the extent that its
proponents suggest. In China physicians screen out patients who appear to be unsuitable.
Acupuncture is not used for emergency surgery and often is accompanied by local
anesthesia or narcotic medication. 
How acupuncture may relieve pain is unclear. One theory suggests that pain impulses are
blocked from reaching the spinal cord or brain at various gates to these areas. Another
theory suggests that acupuncture stimulates the body to produce narcotic-like substances
called endorphins, which reduce pain. Other theories suggest that the placebo effect,
external suggestion (hypnosis), and cultural conditioning are important factors. Melzack
and Wall note that pain relief produced by acupuncture can also be produced by many other
types of sensory hyperstimulation, such as electricity and heat at acupuncture points and
elsewhere in the body. They conclude that the effectiveness of all of these forms of
stimulation indicates that acupuncture is not a magical procedure but only one of many
ways to produce analgesia [pain relief] by an intense sensory input. In 1981, the
American Medical Association Council on Scientific Affairs noted that pain relief does
not occur consistently or reproducibly in most people and does not operate at all in some
people [6].
In 1995, George A. Ulett, M.D., Ph.D., Clinical Professor of Psychiatry, University of
Missouri School of Medicine, stated that devoid of metaphysical thinking, acupuncture
becomes a rather simple technique that can be useful as a nondrug method of pain control.
He believes that the traditional Chinese variety is primarily a placebo treatment, but
electrical stimulation of about 80 acupuncture points has been proven useful for pain
control [7].
The quality of TCM research in China has been extremely poor. A recent analysis of 2,938
reports of clinical trials reported in Chinese medical journals concluded that that no
conclusions could be drawn from the vast majority of them. The researchers stated:
In most of the trials, disease was defined and diagnosed according to conventional
medicine; trial outcomes were
assessed with objective or subjective (or both) methods of conventional medicine, often
complemented by
traditional Chinese methods. Over 90% of the trials in non-specialist journals evaluated
herbal treatments that
were mostly proprietary Chinese medicines. . . .
Although methodological quality has been improving over the years, many problems remain.
The method of
randomisation was often inappropriately described. Blinding was used in only 15% of
trials. Only a few studies
had sample sizes of 300 subjects or more. Many trials used as a control another Chinese
medicine treatment
whose effectiveness had often not been evaluated by randomised controlled trials. Most
trials focused on short
term or intermediate rather than long term outcomes. Most trials did not report data on
compliance and
completeness of follow up. Effectiveness was rarely quantitatively expressed and
reported. Intention to treat
analysis was never mentioned. Over half did not report data on baseline characteristics
or on side effects. Many
trials were published as short reports. Most trials claimed that the tested treatments
were effective, indicating that
publication bias may be common; a funnel plot of the 49 trials of acupuncture in the
treatment of stroke confirmed selective publication of positive trials in the area,
suggesting that acupuncture may not be more effective than the control treatments. [8]
Two scientists at the University of Heidleberg have developed a fake needle that may
enable acupuncture researchers to perform better-designed controlled studies. The device
is a needle with a blunt tip that moves freely within a copper handle. When the tip
touches the skin, the patient feels a sensation similar to that of an acupuncture needle.
At the same time, the visible part of the needle moves inside the handle so it appears to
shorten as though penetrating the skin. When the device was tested on volunteers, none
suspected that it had not penetrated the skin [9].
Significant Risks
Improperly performed acupuncture can cause fainting, local hematoma (due to bleeding from
a punctured blood vessel), pneumothorax (punctured lung), convulsions, local infections,
hepatitis B (from unsterile needles), bacterial endocarditis, contact dermatitis, and
nerve damage. The herbs used by acupuncture practitioners are not regulated for safety,
potency, or effectiveness. There is also risk that an acupuncturist whose approach to
diagnosis is not based on scientific concepts will fail to diagnose a dangerous
condition. 
The adverse effects of acupuncture are probably related to the nature of the
practitioner's training. A survey of 1,135
Norwegian physicians revealed 66 cases of infection, 25 cases of punctured lung, 31 cases
of increased pain, and 80 other cases with complications. A parallel survey of 197
acupuncturists, who are more apt to see immediate complications, yielded 132 cases of
fainting, 26 cases of increased pain, 8 cases of pneumothorax, and 45 other adverse
results [10]. However, a 5-year study involving 76 acupuncturists at a Japanese medical
facility tabulated only 64 adverse event reports (including 16 forgotten needles and 13
cases of transient low blood pressure) associated with 55,591 acupuncture treatments. No
serious complications were reported.The researchers concluded that serious adverse
reactions are uncommon among acupuncturists who are medically trained [11].
Questionable Standards
In 1971, an acupuncture boom occurred in the United States because of stories about
visits to China by various American dignitaries. Entrepreneurs, both medical and
nonmedical, began using flamboyant advertising techniques to promote clinics, seminars,
demonstrations, books, correspondence courses, and do-it-yourself kits. Today some states
restrict the practice of acupuncture to physicians or others operating under their direct
supervision. In about 20 states, people who lack medical training can perform acupuncture
without medical supervision. The FDA now classifies acupuncture needles as Class II
medical devices and requires labeling for one-time use by practitioners who are legally
authorized to use them [12]. Acupuncture is not covered under Medicare. The March 1998
issue of the Journal of the American Chiropractic Association carried a five-part cover
story encouraging chiropractors to get acupuncture training, which, according to one
contributor, would enable them to broaden the scope of their practice [13].
The National Certification Commission for Acupuncture and Oriental Medicine (NCCAOM) has
set voluntary certification standards and certified several thousand practitioners. As of
November 1998, 32 states have licensing laws, with 29 of them using NCCAOM examination as
all or part of their educational, training, or examination requirement, and three with
addditional eligibility criteria. The credentials used by acupuncturists include C.A.
(certified acupuncturist), Lic. Ac. (licensed acupuncturist), M.A. (master
acupuncturist), Dip. Ac. (diplomate of acupuncture), and O.M.D. (doctor of Oriental
medicine). Some of these have legal significance, but they do not signify that the holder
is competent to make adequate diagnoses or render appropriate treatment.
In 1990, the U.S. Secretary of Education recognized what is now called the Accreditation
Commission for Acupuncture and Oriental Medicine (ACAOM) as an accrediting agency.
However, such recognition is not based on the scientific validity of what is taught but
upon other criteria [14]. Ulett has noted: 
Certification of acupuncturists is a sham. While a few of those so accredited are naive
physicians, most are
nonmedical persons who only play at being doctor and use this certification as an
umbrella for a host of unproven
New Age hokum treatments. Unfortunately, a few HMOs, hospitals, and even medical schools
are succumbing to
the bait and exposing patients to such bogus treatments when they need real medical
care.
The National Council Against Health Fraud has concluded:
Acupuncture is an unproven modality of treatment. 
Its theory and practice are based on primitive and fanciful concepts of health and
disease that bear no relationship to present scientific knowledge 
Research during the past 20 years has not demonstrated that acupuncture is effective
against any disease. 
Perceived effects of acupuncture are probably due to a combination of expectation,
suggestion, counter-irritation,
conditioning, and other psychologic mechanisms. The use of acupuncture should be
restricted to appropriate research settings, Insurance companies should not be required
by law to cover acupuncture treatment, 
Licensure of lay acupuncturists should be phased out. Consumers who wish to try
acupuncture should discuss their situation with a knowledgeable physician who has no
commercial interest [15]. 
The NIH Debacle
In November 1997, a Consensus Development Conference sponsored by the National Institutes
of Health and several other agencies concluded that there is sufficient evidence . . . of
acupuncture's value to expand its use into conventional medicine and to encourage further
studies of its physiology and clinical value. [16] The panelists also suggested that the
federal government and insurance companies expand coverage of acupuncture so more people
can have access to it. These conclusions were not based on research done since NCAHF's
position paper was published. Rather, they reflected the bias of the panelists who were
selected by a planning committee dominated by acupuncture proponents [17]. NCAHF board
chairman Wallace Sampson, M.D., has described the conference a consensus of proponents,
not a consensus of valid scientific opinion.
Although the report described some serious problems, it failed to place them into proper
perspective. The panel acknowledged that the vast majority of papers studying acupuncture
consist of case reports, case series, or intervention studies with designs inadequate to
assess efficacy and that relatively few high-quality controlled trials have been
published about acupuncture's effects. But it reported that the World Health Organization
has listed more than 40 [conditions] for which [acupuncture] may be indicated. This
sentence should have been followed by a statement that the list was not valid. 
Far more serious, although the consensus report touched on Chinese acupuncture theory, it
failed to point out the danger and economic waste involved in going to practitioners who
can't make appropriate diagnoses. The report noted: 
The general theory of acupuncture is based on the premise that there are patterns of
energy flow (Qi) through the body that are essential for health. Disruptions of this flow
are believed to be responsible for disease. The acupuncturist can correct imbalances of
flow at identifiable points close to the skin. 
Acupuncture focuses on a holistic, energy-based approach to the patient rather than a
disease-oriented diagnostic and treatment model. Despite considerable efforts to
understand the anatomy and physiology of the acupuncture points, the definition and
characterization of these points remains controversial. Even more elusive is the
scientific basis of some of the key traditional Eastern medical concepts such as the
circulation of Qi, the meridian system, and the five phases theory, which are difficult
to reconcile with contemporary biomedical information but continue to play an important
role in the, evaluation of patients and the formulation of treatment in acupuncture. 
Simply stated, this means that if you go to a practitioner who practices traditional
Chinese medicine, you are unlikely to be properly diagnosed. In 1998, following his
lecture at a local college, an experienced TCM practitioner diagnosed me by taking my
pulse and looking at my tongue. He stated that my pulse showed signs of stress and that
my tongue indicated I was suffering from congestion of the blood. A few minutes later, he
examined a woman and told her that her pulse showed premature ventricular contractions (a
disturbance of the heart's rhythm that could be harmless or significant, depending on
whether the individual has underlying heart disease). He suggested that both of us
undergo treatment with acupuncture and herbs -- which would have cost about $90 per
visit. I took the woman's pulse and found that it was completely normal. I believe that
the majority of nonmedical acupuncturists practice in this manner. The NIH consensus
panel should have emphasized the seriousness of this problem.
