In Z'ev Rosenberg's second book, the scholar-physician shares his insights from his study of discrimination of movement in the vessels in the Nàn Jing. This book provides an accessible window into the world of classic vessel discrimination, and a deep explanation of the Nàn Jing as well as advising how it can inform modern clinical practice. The first chapters of the Nàn Jing examine the parameters of depth, length, qualities, five phase relationships, viscera/bowel, channel/network vessel and season. Ripples in the Flow is designed as a compendium text that provides a commentary on these essential vessel discrimination chapters, as a teaching text, and as a clinical manual for practitioners of both acupuncture and herbal medicine. It will be especially useful for practitioners of five phase approaches to Chinese and Asian medical systems, as it will provide clear classical references for the knowledge that they have been taught in their formal training.
