This 976 page book is the labor of many years of work and is of great importance to the English language body of work on Traditional Chinese Medicine.
From the publisher’s website:
Written by Cheng Wuji and published in 1144, this is a complete commentary on the entire text of On Cold Damage (the Shang Han Lun) in the Song dynasty order. The entire text means that Cheng’s commentary includes the four chapters on the pulse, as well as the chapters on the prohibitions in the back of the Shang Han Lun. All told this adds another 250 lines of text to what has been accepted in the West as the Shang Han Lun. In addition to Cheng Wuji’s commentary, Jonathan Schell has annotated and translated Cheng’s lines with over 1600 lines from the Su Wen, 500 lines from the Ling Shu, 22 Difficulties from the Nan Jing, numerous passages from the Classic of the Pulse (Mai Jing), and commentary from Zhang Jingyue’s Lei Jing, Zhang Zhicong’s commentaries on the Su Wen and Ling Shu, Wang Bing’s commentary on the Su Wen, and as well as numerous other Shang Han Lun commentators. This books has been produced in full color, where the color has been used to show the attributed and unattributed quotes which the commentators use to illustrate their points. This book also includes 52 illustrations with commentary by the translator, 35 of which were composed by Cheng Wuji and 17 which have been composed by Jonathan Schell. This book illustrates the pinnacle of classical thought, where the reader, through the annotations can trace Cheng’s thought process and apply the canonical texts of Chinese medicine, as cited by Cheng, to the understanding of the Shang Han Lun.
