title: Systematic review on herb-induced liver injury in Korea.
abstract: Herbal drugs are generally regarded as safe due to their extensive clinical use especially in East Asian countries. However, the potential toxicity of herbal drugs has become an important medical issue recently, resulting in numerous reports of drug-induced liver injury (DILI). Here, we performed a systematic review of herbal medicines with the potential to cause hepatotoxicity in Korea. A literature search of six databases, including PubMed and five Korean electronic databases, was performed to identify cases of herb-induced liver injury (HILI) in Korea, yielding 31 unique reports, including 21 single herb and 10 multi-herb preparations. From these reports, we identified 97 cases of HILI (47 males, 49 females, and 1 unknown sex) consisting of 74.7% hepatocellular-type injury, 10.8% cholestatic-type injury, and 14.5% mixed-type injury. Causative agents included 21 unique herbal preparations, including 11 single species and 10 multispecies, with Polygoni Multiflori (39.2%) and Dictamnus dasycarpus (37.1%) as the most frequent agents. These analyses presented a feature of HILI, and produced a comprehensive list of herbs with a higher risk of hepatotoxicity in Korea. Further studies will be necessary to ascertain the mechanisms by which these herbs induce HILI and to determine whether these effects are specific to the Korean population.
