Summary
Botanical supplements can cause liver damage (hepatotoxicity), even when the toxic component isn't obvious. Research is needed to understand these risks and improve safety assessments for herbal products.
Area of Science:
- Toxicology
- Pharmacology
- Natural Product Chemistry
Background:
- Botanical dietary supplements (herbal products) are widely used in the U.S.
- Increasing use correlates with reported adverse effects, including serious hepatotoxicity.
- Mechanisms of botanical-induced liver injury are often unclear, even when toxic components like pyrrolizidine alkaloids are present.
Purpose of the Study:
- To establish a scientific foundation for understanding botanical-induced hepatotoxicity.
- To develop improved methods for assessing and predicting liver toxicity from herbal products.
Main Methods:
- A workshop was convened by the National Center for Natural Product Research (NCNPR) and the FDA's Center for Food Safety and Applied Nutrition (CFSAN).
- 22 experts presented findings and discussed challenges in botanical safety.
- 65 individuals attended the workshop focused on hepatotoxicity assessment.
Main Results:
- Highlighted the association between certain botanical supplements and severe liver damage.
- Identified gaps in knowledge regarding the causative agents and mechanisms of hepatotoxicity.
- Emphasized the need for better scientific tools for risk assessment.
Conclusions:
- Further research is critical to elucidate the mechanisms of botanical-induced hepatotoxicity.
- Enhanced assessment and prediction tools are necessary to ensure the safety of herbal products.
- Collaboration between research institutions and regulatory bodies is key to addressing these public health concerns.
