The fourth of an encyclopedic four-volume set describing the basic physiology, chemical sensitivity, diagnosis, and treatment of chronic degenerative disease, this text focuses on treatment techniques, strategies, protocols, prescriptions, and technologies. Distinguishing itself from previous works on chemical sensitivity, it explains newly understood mechanisms of chronic disease and hypersensitivity involving core molecular function. It discusses new information on ground regulation system, genetics, the autonomic nervous system, and immune and non-immune functions. It includes the latest technology and cutting-edge techniques, numerous color figures, and supporting research.
