What is Acupuncture ?

Acupuncture (from Latin, 'acus' (needle) + 'punctura' (to puncture)) is a form of alternative medicine and a key component of traditional Chinese medicine (TCM) involving inserting thin needles into the body at acupuncture points. It can be associated with the application of heat, pressure, or laser light to these same points. Acupuncture is commonly used for pain relief, though it is also used for a wide range of conditions. Clinical practice varies depending on the country. It is rarely used alone but rather as an adjunct to other forms of treatment. TCM theory and practice are not based upon scientific knowledge, and acupuncture is described as a type of pseudoscience.

The conclusions of many trials and numerous systematic reviews of acupuncture are largely inconsistent. Cochrane reviews found acupuncture is not effective for a wide range of conditions. An overview of high-quality Cochrane reviews suggests that acupuncture may alleviate certain kinds of pain. A systematic review of systematic reviews found that for reducing pain, real acupuncture was no better than sham acupuncture.The evidence suggests that short-term treatment with acupuncture does not produce long-term benefits. Some research results suggest acupuncture can alleviate pain, though other research consistently suggests that acupuncture's effects are mainly due to placebo. A systematic review concluded that the analgesic effect of acupuncture seemed to lack clinical relevance and could not be clearly distinguished from bias.

Acupuncture is generally safe when done by an appropriately trained practitioner using clean technique and single-use needles. When properly delivered, it has a low rate of mostly minor adverse effects.Between 2000 and 2009, at least ninety-five cases of serious adverse events, including five deaths, were reported to have resulted from acupuncture. Since serious adverse events continue to be reported, it is recommended that acupuncturists be trained sufficiently to reduce the risk. A meta-analysis found that acupuncture for chronic low back pain was cost-effective as an adjunct to standard care, while a systematic review found insufficient evidence for the cost-effectiveness of acupuncture in the treatment of chronic low back pain.

Scientific investigation has not found any histological or physiological evidence for traditional Chinese concepts such as qi, meridians, and acupuncture points. Many modern practitioners no longer support these concepts and have abandoned the concepts of  and meridians. Acupuncture is currently used widely throughout China and many other countries, including the United States. It is uncertain exactly when acupuncture originated or how it evolved, but it is generally thought to derive from ancient China. In the early 19th century, an interest arose both in the US and Europe.Acupuncture is identified by Chinese people globally as part of their intangible cultural heritage.
