[mass noun]a system of complementary medicine in which fine needles are inserted in the skin at specific points along what are considered to be lines of energy (meridians), used in the treatment of various physical and mental conditions 针刺疗法
Acupuncture has been practised in China for more than 4,500 years and is increasingly popular in the West. Acupuncturists believe that treatment works by countering an imbalance of energy in the body; recently some scientists have suggested that the needles may stimulate the body's endorphins or naturally occurring painkillers
