Acupuncture (from Lat. acus, "needle" (noun), and pungere,
"prick" (verb) or in Standard Mandarin, zhe¯n ji?
(??) is a technique of inserting and manipulating needles into "acupuncture
points" on the body. According to acupunctural teachings this
will restore health and well-being. The definition and characterization
of these points is controversial. Acupuncture is thought to have
originated in China and is most commonly associated with Traditional
Chinese medicine. Other types of acupuncture (Japanese, Korean,
and classical Chinese acupuncture) are practiced and taught throughout
Whether acupuncture is efficacious or a placebo is subject to scientific
research. There is no scientific consensus over whether or not evidence
supports efficacy. Reviews of existing clinical trials have been
conducted by the Cochrane Collaboration and Bandolier according
to the protocols of evidence-based medicine; some reviews have found
efficacy for headache and nausea, but for most conditions have concluded
a lack of effectiveness or lack of well-conducted clinical trials.
The World Health Organisation (WHO), the National Institute of Health
(NIH), the American Medical Association (AMA) and various government
reports have also commented on acupuncture. These groups disagree
on what is acceptable evidence and on how to interpret it..
