“…In particular, herb-induced liver injury (HILI), which has varying incidence from 0% to 1.92% in Korea, has been the topic of debates (Oh et al, 2015;Shahbaz, Mahajan, & Lewis, 2017). Research for HILI on certain diseases includes musculoskeletal disorders, atopic dermatitis, and type 2 diabetes (Lee, Shin, et al, 2015;Tian et al, 2016;Yun et al, 2017).
