Abstract

In recent years, herbal tea consumption becomes popular because of the potential health benefits and attractive flavors. However, there is also a growing concern that herbal supplements contribute to the drug-drug/drug-herb interactions and hepatotoxicity. In this study, FL83B mouse hepatocytes were used as an in vitro mode of hepatotoxicity induced by free fatty acids, including palmitic acid (PA) and oleic acid (OA), ethanol, and acetaminophen. Herbal tea extracts were obtained from eight common herbal plants, including Verbena officinalis L., Hyssopus officinalis L., Salvia officinalis L., Urtica dioica L., Hemerocallis fulva (L.) L., Citrus maxima (Burm.) Merr., Citrus limon (L.) Osbeck, and Ficus formosana Maxim. MTT assay was used to evaluate the impact of these herbal tea extracts on hepatoxocitity. We found that these herbal tea extracts per se did not exhibit hepatotoxicity, and had no effect on OA-induced hepatotoxicity. However, extracts from Verbena officinalis L., Hyssopus officinalis L., Salvia officinalis L., and Hemerocallis fulva (L.) L. exhibited protective effect against PA-induced hepatotoxicity. In addition, herbal tea extracts from Verbena officinalis L., Hyssopus officinalis L., Salvia officinalis L., Urtica dioica L., Hemerocallis fulva (L.) L., and Ficus formosana Maxim. exhibited protective effect against acetaminophen-induced hepatotoxicity. Interestingly, all these herbal tea extracts enhanced ethanol-induced hepatotoxicity. Our results suggest that herbal tea extracts have differential effects on different modes of hepatotoxicity.
