'This book is like warm spring water transmitting profoundness in a very calm, non-invasive way to argue the points. It is a mentor, gently holding students' hands, and the angle and content are practice orientated. The introduction section alone accelerated my learning by years and the accurate and insightful translation of the key words illuminates some of the crucial background of Chinese thinking.'

'"Gather wood without the forester and you will soon become lost in the forest," advises the Yijing. Bertschinger is a consummate guide through the forest of China's earliest medical writings. This insightful and beautifully wrought commentary on the Yellow Emperor's Classic is essential reading for the beginning, middle and end of your studies.'

'When educating acupuncturists to work in the western world, many of us have emphasised, quite rightly, the need for complementary practitioners to become familiar with scientific medicine and with western medical practice. This tremendous work provides the opportunity and the medical content for an equal and opposite perspective to be emphasised. All western doctors from now on should be expected to read Richard Bertschinger as a serious part of their initial medical education.'
