Abstract
Herbal and dietary supplements represent a multi-billion-dollar industry reportedly used by over half of American adults. However, these products are not regulated by the Federal Drug Agency and contain a wide range of contaminants, leading to over 50,000 adverse events each year. This review aims to highlight the widespread use and current regulatory status of herbal and dietary supplements, identify the presentation and diagnostic dilemmas faced with liver injury, and discuss the most common agents implicated in herbal and dietary supplement hepatotoxicity.
