Acupuncture
Acupuncture involves inserting small needles into various points, 'acupoints', in the body to stimulate nerve impulses.
Traditional Chinese acupuncture is based on the idea of 'qi' (vital energy) which is said to travel around the body along 'meridians' which the acupuncture point affect.
Western acupuncture uses the same needling technique, but is based on affecting nerve impulses and the central nervous system, and can also include the use of herbs, electricity, magnets and lasers.
