Two naturopaths introduce us to the world of brain biochemistry, translating the science into common English, so that we can understand the potential power of herbs and nutrients to enhance health, prevent disorders and affect existing health disorders. These alternatives, or supplements, to medication are increasingly being used to help treat health conditions with a psychological component - from Attention Deficit Disorder and anorexia to insomnia, menopause and Parkinson's Disease. Authors Meletis and Barker explain 18 of these conditions, and review the most current research into how - or whether - the use of herbs and supplements has been proven to prevent, affect or remove these health conditions, or at least some of their symptoms. Can the Chinese herb Salvia curb cravings in alcoholics? Can niacin help treat anxiety? Other herbs, nutrients and conditions addressed include the use of zinc to reduce symptoms of anorexia and bulimia, ginkgo biloba for Alzheimer's and 5-HTP for depression. Appendices list the top 20 brain-enhancing herbs and supplements, and nutrient deficiencies and their links to health and brain function. It is not the intention of this book to advocate the replacement of standard drug therapy, but for the integration of these "natural medicines" with traditional medical treatments. Consumers are urged to discuss these herbs and nutrients with their physician before beginning use, as some allergic reactions or interactions with traditional medicines can occur. The central argument of this book is that when properly nourished, people can operate at maximum physical and mental capacity, with maximum ability to fend off or recover from disease and disorder.
