In addition to offering a comprehensive understanding of the art of tongue diagnosis, this book includes ancient and modern healing practices based on Healing Tastes, Herbal Therapies and Dietary Protocols. The knowledge contained in this book is invaluable for supporting oneself and others on the journey to wholeness. The educational foundation of the book prepares us to really understand the meaning and use of tongue diagnosis. The ancient art of tongue diagnosis, as this book defines it, is "the science of the shape, shadings and markings of the tongue, which describe the current state of an individual's health, as well as their inherited constitution." The potential of tongue diagnosis is that it gives a non-invasive way to measure the tissue integrity of the body, especially the Agni of the digestive system or the Fire or strength of the digestive system. This can be assessed by simply observing the colour and structure of the tongue, then we have a very simple way to take preventive steps to correct those imbalances, and we have a very simple feedback system, meaning the tongue's colour, size, shape and shading, to let us know how successful our approach has been.
