Traditional Chinese medicine has a long and complex history, yet the basic principles at the heart of practice have remained the same for hundreds of years. Without a solid understanding of these fundamental theories, effective practice is impossible, and this book provides a complete introduction to everything that students and practitioners, both new and experienced, need to know. The book describes and explains all of the fundamental principles of Traditional Chinese Medicine, including yin/yang, the five elements, the 'zang and fu' organs, Zang Xiang, Qi, and the meridians and collaterals of the body. Explaining not only the principles upon which these elements work, but also how they interrelate, the book describes how they can be used in practice to identify, treat and prevent ill-health and disease. This thorough and accessible textbook, compiled by the China Beijing International Acupuncture Training Center (CBIATC), under the editorial directorship of leading Chinese clinicians Zhu Bing and Wang Hongcai, is essential reading for students of traditional Chinese medicine, and is also a useful basic reference for TCM practitioners.
