Originally published in 1985, updated with a 2010 preface. Dispassionately lays out key points in the history of Chinese medical thought from the Shang Dynasty up through the Cultural Revolution, where acupuncture gets credit for its analgesic properties. See this in action in Antonioni's 1972 documentary Zhong Kuo, filmed in China and famously showing a conscious and smiling woman having her belly cut open for a Caesarian, no pain killers (we're assured) apart from acupuncture needles surrounding the incision.
