Model ear showing acupuncture points, 1970-1985.

UNSPECIFIED - JULY 20: Model of an ear, probably from China or Japan, showing the points along the meridians where acupuncture needles are inserted. Acupuncture is a medical technique which has been practised in China for over 3000 years. It consists of the insertion into the skin of fine needles, at the points or meridians relating to the tissue or organ believed to be disordered. By inserting the needles into the paths taken by the �chi� or �qi�, the life force which flows around the body, the paths become unblocked and harmonious energy flow and good health is restored. Acupuncture became a very popular form of alternative therapy in the West in the 1970s, at a time when there was considerable interest in Eastern philosophies and religion.
