Herbal Products: Toxicology and Clinical Pharmacology, Second Edition builds on the informative foundation laid by its predecessor. This fully revised and expanded second edition boasts more than 200 new references that document efficacy studies and adverse effects and four new chapters devoted to dietary products. Practitioners and researchers will find that this volume is a comprehensive resource for objective clinical information about the potential uses, efficacy, and safety of herbal medicines. The authors recognize that the majority of available information on dietary supplements is typically provided by distributors and designed to sell a product rather than objectively inform consumers; therefore, the emphasis throughout is on information not readily available from any other source. Similar to the first edition, this volume is based on original studies published in peer-reviewed journals, as well as meta-analyses, systematic reviews, and other high-quality assessments by recognized experts.
