I agree with the other reviews of this book - it is outstanding. One feature which should not be overlooked is that work was written in the 30s, and pre-dates the Maoist revisions of 'TCM' - there is still not a whole lot of material on the 'spiritual' aspects of points, etc., which many say were weeded out during the revisions, but it is still the most thorough textbook available on Chinese Medicine which is not largely shaped by the homogenizing efforts of the Cultural Revolution.
