Acupuncture is an important practice in Chinese Medicine to prevent and treat diseases (or patterns of disharmony, as called in Chinese Medicine).
The concept is to puncture certain points of the body with needles or, in other schools, to apply pressure or even laser beams on those points.
It is widely recognized, even by modern medical standards, as having a marked efficacy. It only requires simple equipment and has been widely popular in China and elsewhere for thousands of years.
