It seems as though every day brings a new pill or potion claiming to restore mental alertness or improve memory. While many of these claims are based on factual information, many others are not. This encyclopedia of foods and drugs that are believed to improve mental performance contains information on nearly 400 nutrients, herbs, and drugs, ranging from ancient plant compounds to the latest pharmaceuticals. Entries are arranged by type of substance, such as foods, vitamins, minerals, spices, and medical drugs. Each entry contains information such as alternate names and forms, sources, results, side effects, precautions, and recommended dosage. Although readers are encouraged to consult with their doctors before diagnosing and treating themselves, this book provides crucial, factual, and unbiased information on the ''miracle drugs'' that many people believe can solve health problems from fatigue to Alzheimer's. Readers can discover for themselves the properties of each substance. A complete index allows for easy reference and help with alternate names, food and drug interactions, and symptoms.
