ACUPUNCTURE
Acupuncture is the procedure of inserting and manipulating filiform needles into various points on the body to relieve pain or for therapeutic purposes. The word acupuncture comes from the Latin acus, "needle", and pungere, "to prick". In Standard Mandarin, acupuncture is called (zhēnbiān), or a related word, 針灸 (zhēnjiǔ), which refers to acupuncture together with moxibustion According to traditional Chinese medicine, acupuncture points are situated on meridians along which qi (a "life energy"), flows. Modern acupuncture texts present them as ideas that are useful in clinical practice and continue to inform the practice of acupuncture, but there is no evidence to support their existence and they have not been reconciled with contemporary knowledge about biology, physics or chemistry. Acupuncture's origins in China are uncertain. One explanation is that some soldiers wounded in battle by arrows were cured of chronic afflictions that were otherwise untreated, and there are variations on this idea. In China, the practice of acupuncture can perhaps be traced as far back as the Stone Age, with the Bian shi, or sharpened stones. In 1963 a bian stone was found in Duolon County, Mongolia, pushing the origins of acupuncture into the Neolithic age.[28] Hieroglyphs and pictographs have been found dating from the Shang Dynasty (1600-1100 BCE) which suggest that acupuncture was practiced along with moxibustion. Despite improvements in metallurgy over centuries, it was not until the 2nd century BCE during the Han Dynasty that stone and bone needles were replaced with metal. The earliest records of acupuncture is in the Shiji (史 記 , in English, Records of the Grand Historian) with references in later medical texts that are equivocal, but could be interpreted as discussing acupuncture. The earliest Chinese medical text to describe acupuncture is the Huangdi Neijing, the legendary Yellow Emperor's Classic of Internal Medicine (History of Acupuncture) which was compiled around 305–204 B.C. The Huangdi Neijing does not distinguish between acupuncture and moxibustion and gives the same indication for both treatments. The
Mawangdui texts, which also date from the second century BC though antedating both the Shiji and Huangdi Neijing, mentions the use of pointed stones to open abscesses and moxibustion but not acupuncture, but by the second century BCE, acupuncture replaced moxibustion as the primary treatment of systemic conditions
