Description

Plants have been the primary source of drugs for millenia; today, many manufacturers claim that their plant-based "neuroceuticals" can offer powerful benefits in brain function. However, the US government does not require them to demonstrate their products' effectiveness. This book provides crucial information that can help consumers and medical professionals objectively assess these claims. Two leading experts introduce the fundamental principles of pharmacology, explaining how drugs and natural products can affect the body's organs and organ systems. Using examples, they show how to determine whether an ingested substance can enter the bloodstream and reach its target at a concentration sufficient to have an effect. They also explain how natural products may influence blood levels of other substances, and discuss whether such interactions may diminish the effectiveness of prescription medications or alter normal body chemistry. Throughout, they emphasize factors relating especially to neuroceuticals and the brain. Individual chapters are devoted to nutritional supplements which promise to enhance memory, relieve pain, safely promote sleep, and aid in the treatment of depression or anxiety. Specifically, readers will find research-based coverage of Ginkgo biloba; St. John's Wort; Valerian; Lemon Balm; Kava; Lavender; Kudzu, Daffodil, Passion Flower, and Camellia Tea and other caffeinated beverages.
