Did you know?

In Latin, acus means "needle", and the English word acupuncture was coined way back in the 17th century to describe a technique the Chinese had already been using for 2,000 years. An acupuncturist may insert many extremely fine needles at a time; the treatment is usually uncomfortable but not truly painful. In China today, even major surgery is often carried out using only acupuncture to kill the pain; it's also used for many other conditions, including insomnia, depression, smoking, and overweight. Acupuncture is based on ancient theories of bodily energy that few Western doctors have ever accepted; but even though attempts to explain its effects by Western science have been unsuccessful, it's now widely recognized by doctors as effective for pain reduction.
