Evidence-Based Botanical Research: Applications and Challenges

Use of herbal supplements is on the rise around the world, but limited data exist on the safety and efficacy of botanical products. Efforts to subject botanicals to rigorous scientific research began recently. There are many problems associated with botanicals research, however. These include procuring the study agents, selecting appropriate study method and clinical trial design, navigating through regulatory obstacles, and obtaining funding. Evidence-based botanical research can help to validate traditional uses and to facilitate new drug development. Concerted efforts of governmental agencies and industry are essential to ensure continuance of high-quality botanicals research.
