Botanical-induced toxicity: Liver injury and botanical-drug interactions. A report on a society of Toxicology Annual Meeting symposium

Abstract

Botanical supplements and herbal products are widely used by consumers for various purported health benefits, and their popularity is increasing. Some of these natural products can have adverse effects on liver function and/or interact with prescription and over-the-counter (OTC) medications. Ensuring the safety of these readily available products is a crucial public health concern; however, not all regulatory authorities require premarket safety review and/or testing. To address and discuss these and other emerging needs related to botanical safety, a symposium was held at the Society of Toxicology Annual Meeting in Salt Lake City (UT) on March 11, 2024. The symposium addressed the latest research on botanical-induced liver toxicity and botanical-drug interactions, including new approach methods to screen for toxicity, challenges in assessing the safety of botanicals, and relating human adverse events to specific products. The presentations and robust panel discussion between the speakers and audience highlighted the need for further research and collaboration to improve the safety of botanical supplements and herbal products, with the ultimate goal of protecting consumer health. Although utility of many of the modern tools presented in the symposium requires further study, the synergistic efforts of diverse experts hold promise for effective prediction and evaluation of botanical-induced hepatotoxicity and botanical-drug interaction potential.
