Acupuncture has deeper roots than the Han Dynasty. Sharpened stones and bones that date from about 6000 BCE. have been found and were probably used as instruments for acupuncture treatment. However, the first document that described an organized system of diagnosis and treatment now known as acupuncture is The Yellow Emperor’s Classic of Internal Medicine, written about 100 BCE. The work was a compilation of Daoist beliefs,
and is still used in some therapeutic techniques. The concept of meridians in which Qi flowed developed later. During the Han, acupuncture began to become codified and became a standard medical practice. Acupuncturists used needles and stuck them in precise areas of the body, or the meridians, resulting in no pain to the recipient. Where a needle was placed was crucial. After 15-60 minutes, the needles were painlessly removed. Acupuncture has been noted to produce a variety of effects on the body, including increases in blood circulation and temperature, development of white blood cells, reduce cholesterol, and regulate blood sugar levels.
