Evaluation of the Four Most-used Alternative Medicine Databases to Answer Common Herbal Information Questions

ABSTRACT Selecting the right tool to answer herbal product questions is essential for medical and information professionals. This study's objective was to compare and evaluate the four most-used alternative medicine databases in terms of adverse reactions, therapeutic use, interactions, and dosage of specific herbal products. MICROMEDEX (AltMedDex and POISINDEX), The Review of Natural Products (eFacts), Natural Medicines Comprehensive Database, and Natural Standard were compared for their completeness in answering patient questions related to garlic, Echinacea, saw palmetto, ginkgo, and cranberry. The results of this study will be helpful in making better database usage or purchasing decisions by librarians, pharmacists, and other medical professionals.
