Acupuncture is a method of treatment in which the therapeutic effect is achieved by inserting a sharp thin needle into special points in the body, called points of acupuncture or simply acu-points.
The origins of acupuncture are unknown. The oldest books about acupuncture were written probably in the time of Warring States, and were recorded in later bibliographies of Han dynasty dating approximately 200 BCE – 200 CE. Ancient Chinese were very skilled in iron casting, and technically were able to produce acupuncture needles about the 5th – 4th century BCE. Before that time they probably used “needles” made of fish bones, animal bones and/or stones.
For more than two millennia acupuncture was developing in China and was a part of Chinese Medicine
