This book is intended to be the companion volume to the “Foundations of Chinese Medicine”, setting out the application of the theory of Chinese medicine to the treatment of specific diseases with both acupuncture and Chinese herbs. The discussion is centred around the old Chinese disease-symptoms, e.g. “headache”, “dizziness”, “abdominal pain”, etc. Although these are normally referred to as “diseases” in Chinese medicine, they are symptoms rather than diseases in a Western medical sense. In a few cases, however, I do discuss actual diseases as defined in Western medicine; these are asthma, allergic rhinitis, sinusitis, nephritis, myalgic encephalomyelitis, Parkinson’s disease, multiple sclerosis, the common cold and influenza. This textbook sets out the treatment for 34 common diseases. With four exceptions – asthma, allergic rhinitis, myalgic encephalomyelitis (ME) and multiple sclerosis – all appear in textbooks of Chinese medicine. The theory of allergic asthma and allergic rhinitis presented in this book is entirely new; of course, it is far from perfect and will need constant revision according to clinical experience and research. The theory of ME, similarly new, is based on my own clinical experience, although the concepts of “residual pathogenic factor” and “Latent Heat” on which it is based are very old.
