This is a text which provides a contemporary approach to the use of lifestyle, herbal and nutritional interventions in health care. While conventional health care has long classified many nutritional and herbal remedies as folklore, there is increasing scientific evidence to support a number of 'old wives tales'. This book demonstrates the biological plausibility of using supplements in clinical care and supports the scientific validity of such interventions by referring to clinical trials. It provides the health professional with therapeutic protocols that can be used to manage or support other treatment regimes in promoting health, preventing and treating disease. The book is divided in to 3 parts. Part 1 considers the principles of nutritional intervention. Part 2 list prevalent diseases and provides a therapeutic protocol for their management. Part 3 lists nutrients (and some frequently used herbs) and seeks to catalogue the indications, doses, interactions and side effects that require consideration when providing safe and effective clinical care.
