The work of sinologists Claude Larre and Elisabeth Rochat de la Vallée allows us access to the origins of Chinese medicine. Through their detailed study of the Nei jing, Nan jing and their commentaries, we are connected to the perceptive minds of the classical authors. Claude Larre's profound understanding of the philosophical and cultural background and Elisabeth Rochat's thorough knowledge of the medical classics provide a unique insight into the eight extraordinary meridians and the fundamental interaction of yin and yang within the body.
