Acupuncture is a traditional Chinese therapy based on sticking needles into the dermis at precise points. Acupuncture is often described as "gateway woo"[1] because of the increasing number of scientists and medical centers accepting it as respectable treatment.

While many doctors don't believe in chi or meridians, it is widely believed that acupuncture is more effective than randomly stabbing someone with needles while telling them it helps, despite a serious lack of quality randomized clinical trials (RCTs) and a nearly completely-unknown mechanism of action.[2] This belief is apparently because needles have less of a "magic" vibe than other forms of woo. Despite spending considerable sums of money, acupuncture researchers have yet to show consistent, statistically significant, and relevant effects in proper clinical trials.[3] Although a few small-sample (case, or case series) studies including an n=57 randomized placebo-controlled study from 2009 suggest acupuncture can increase fertility in infertile patients,[4] as later editorials and papers asserted, these results, "should be considered preliminary awaiting further supporting evidence,"[5] and, "[t]he current evidence showing that acupuncture might improve poor semen quality is insufficient because of the small number of studies, inadequacy of procedures and/or insufficient information for semen analysis, high levels of heterogeneity, high risk of bias, and poor quality of reporting. Further large, well-designed RCTs are required."[6]

Technique

Acupuncture can relieve anger, too.

Its theoretical basis is that health and sickness are caused by the good or bad flow of chi through the body, in particular along the twelve major meridians of the body (though some authorities list fourteen or even more) which run from head to toe along the body, and which are associated with the bladder, gallbladder, heart, large intestine, small intestine, kidneys, liver, lungs, spleen, stomach, pericardium, and "triple heater" (三焦) also known as "triple burner" in English. "Triple heater" is by necessity a literal translation from the Chinese: as there is no such organ, there is no correct medical term for it.[note 1]

The acupuncturist treats the ailments of these various parts by inserting needles at points lying on these meridians, known simply as "acupuncture points" and manipulating the needles to increase or decrease the flow of chi along that meridian.

Variants on acupuncture include auricular acupuncture, which involves sticking needles into particular parts of the outer ear, which supposedly correspond to different body parts (essentially reflexology with ears instead of feet); electroacupuncture, in which the needle carries a small electric current; and moxibustion, in which moxa (the plant commonly known as mugwort, Artemisia vulgaris) is set smouldering on the appropriate acupuncture point. Acupuncture can also be used to perform bloodletting.[7] This is supposed to be good for a long list of unrelated diseases. Chinese bloodletting is banned in California.[8]

Origins

Shennong, eating a branch

Unlike many remedies which appeal to the New Age, acupuncture is genuinely pre-scientific and genuinely Asian. The earliest surviving text dealing with acupuncture is the Chinese text The Yellow Emperor's Classic of Internal Medicine, dating from about 300 BCE, well before any scientific understanding of disease, including germ theory, cell theory, and basic biology such as neurology. According to the text, sometime around 3000 BCE, acupuncture was invented by the Chinese god Shennong.[9]

Acupuncture lost ground in China from the 17th century onwards, with the introduction of Western medical ideas. It regained some of its prestige, starting with Mao Zedong and the Chinese Communist Party advocating Traditional Chinese Medicine following the end of the civil war. The publication in 1951 of The New Acupuncture by Zhu Lian[10] was central to repopularizing acupuncture.[11]:18

Although the basics of acupuncture have remained the same since ancient times, the system has suffered the inevitable mutations and accretions: the original system, for example, had 365 acupuncture points; some modern systems catalog as many as 2000. There is no science to support even one point, and inventing more of them just gets more patients to pay money.

Efficacy

Your tax dollars at work doing nothing — or possibly spreading disease.

Sticking needles into people can cause the release into the bloodstream of endorphins and natural steroids such as cortisol. The medical version of this is called intramuscular stimulation and is of some use in the management of chronic pain. Acupuncture, to the extent it works, seems to do so in this manner. The pain relief from acupuncture seems to be mediated solely through the release of endorphins, as any perceived analgesic effect is reduced or eliminated when the patient has been pretreated with an opioid antagonist such as naloxone.[12] However, the few supposed studies that show efficacy have been criticized for poor design, poor analysis and poor results.[13] In fact, if acupuncture were held to the same standards as all other medications and drugs, the poor quality of the studies would have prevented it from ever being approved for use by the FDA.[14]

As to the wider claims of acupuncturists, it seems on the face of it unlikely, given the unscientific basis of their claims, that they can have much effect on a patient's physiology by manipulating the flow of a non-existent substance around imaginary meridians. The James Randi Educational Foundation noted that in studies using "no needles vs needles," the methodology of the study is an important consideration.[15]

However, a recent study using an MRI to view brain activity during an acupuncture session found that specific acupuncture points have distinct effects on cerebral activity in specific areas that are not otherwise predictable anatomically.[16]

Acupuncture anesthesia

The biggest publicity generator for TCM in West in the early 1970s was acupuncture analgesia for surgery, which was publicized by James Reston, a New York Times reporter who accompanied Secretary of State Henry Kissinger to China in 1971, in preparation for President Richard Nixon's visit in 1972. Reston had an emergency appendectomy while in China using conventional anesthesia,[11]:138 and received post-surgical acupuncture analgesia, which he described as causing diversionary pain.[17] Acupuncture analgesia has been portrayed elsewhere as occurring during surgery,[11]:138-140 but this has largely been debunked: when acupuncture has been used during surgery, it has been used in addition to chemical sedatives.[18][19][20][21]

Intermittent diseases

It is noticeable that acupuncturists tend chiefly to advertise their abilities to treat precisely those ailments which are chronic but intermittently better or worse (headaches, acne), or which often have a strong psychosomatic element (impotence, asthma), or which are guaranteed to clear up rapidly anyway (the common cold), and are therefore profiting from the placebo effect and regression to the mean.[note 2]

Disease

It has also been found that far from curing disease, acupuncture has been a transmission agent for hepatitis C, Methicillin-resistant Staphylococcus aureus and acupuncture mycobacteriosis.[22] In one prospective study of 190,924 acupuncture patients, the rate of "serious adverse events (death, organ trauma or hospital admission)" was found to be 0.024%.[23] In another prospective study of 229,230 patients, the rate of "adverse events requiring specific treatment" was found to be 2.2%.[23]

Dr. Offit writes, "The final argument against acupuncture is the hardest to refute. Acupuncture needles are not without risk. … At least eighty-six people have died from acupuncture."[24][25] Unfortunately, almost no reporting mechanism exists for acupuncture, and so the true harms are hard to estimate.

Acupressure

Acupressure is acupuncture without the needles.

Acupressure is part of the Western bundle of hypotheses and practices known as traditional Chinese medicine. You press on acupuncture pressure points to affect the meridian system and bring about relief by rebalancing yin, yang and qi. Apparently.

Effectiveness

Considering the needles are the one bit of acupuncture that appears to do anything at all, with the rest of the theory being woo, acupressure is, unsurprisingly, not much good. Studies show[26] possible effects, such as interaction with the body's pain reduction systems, but at a level that is not statistically significant. Studies are ongoing.
