Discussion on the location of Dazhui (GV 14) and Yaoyangguan (GV 3)

Abstract

Since the anatomical location of acupoints was recorded in The latest Practice of Western Acupuncture in 1915, and Lecture Notes on Advanced Acupuncture in 1931, the Japanese acupuncture works of Chinese translation version, the location of Dazhui (GV 14) (under the spinous process of the 7th cervical vertebra) and Yaoyangguan (GV 3) (under the spinous process of the 4th lumbar vertebra) had rarely been questioned for nearly a century. In order to confirm the above statement, the writers have reviewed ancient literature, combined with the modern anatomical knowledge and searched the evidences from the core arguments of the acupuncture Mingtang chart and the bronze acupuncture statue. It is believed that Dazhui （GV 14） should be positioned under the spinous process of the 1st thoracic vertebra, and Yaoyangguan（GV 3） be under the spinous process of the 5th lumbar vertebra. Accordingly, all of the other acupoints of these meridians should be moved down by 1 vertebra, i.e. those on the governor vessel from Dazhui (GV 14) to Yaoyangguan (GV 3), those on the 1st lateral line of the bladder meridian of foot-taiyang from Dazhu (BL 11) to Baihuanshu (BL 30) and those on the 2nd lateral line of the bladder meridian from Fufen (BL 41) to Zhibian (BL 54).
