"Much-needed...A valuable reference text for herbalists, physicians, researchers, policymakers, and all other professionals with an interest in this area. Provides the reader with the essential background about psychoactive herbs. This is an outstanding summary that covers commonly used herbal supplements such as ginseng as well as the more exotic plant-based options such as hallucinogenic mushrooms."

"A scientifically sound introduction to the role of herbs in mental health. This well-written book provides an informative overview of the topic. It offers an unbiased view of the current state of knowledge of various herbs and their potential psychoactive properties. Dr. Spinella clearly differentiates folklore from proven clinical fact, highlighting the importance of well-designed clinical trials to determine the effectiveness of any compound throught to affect mood and behavior."

"Until now, the average person interested in the psychopharmacology of herbals did not have access to an easily understandable and reputable source of information. This book will be helpful to health care practitioners and patients who are not well versed in the therapeutic utility and potential risks associated with herbal preparations. Health care practitioners will be better prepared to provide intelligent advice to patients who take over-the-counter herbal medications."
