In this twenty-first century our external environment contains innumerable hazards to our health and wellbeing. These impose new and ever greater challenges to our immune systems. As our immune systems become over-loaded and the number and variety of medical problems from which we suffer increases. Often conventional medicine is ill-equipped to deal with these problems. In consequence dealing with chronic illness is becoming a growing burden for society and healthcare providers. In Lymphatic Therapy for Toxic Decongestion Margaret McCarthy describes the relationship between degenerative disease and physiological malfunction within the body. She then goes on to demonstrate how an integrated therapy, which draws on a variety of approaches, may be used to assess the body as a whole and to promote restoration of health simply, effectively and economically, without the use of expensive drugs or equipment.
