The Application of Yin Chen Wu Ling San on Drug-Induced Liver Injury

Drug-induced liver injury (DILI) is an illness that can be triggered by the use of almost any class of medication. Although some cases of DILI are resolved without intervention, some can cause liver cirrhosis or jaundice. In the presented case, Professor Huang Huang demonstrates the use of two classical prescriptions – Yin Chen Hao Tang (Virgate Wormwood Decoction) and Yin Chen Wu Ling San (Virgate Wormwood and Five-Ingredient Powder with Poria) – in the treatment of a 52-year-old female who arrived in clinic with jaundice, a symptom of DILI, after self-medicating with herbs for a case of COVID-19. Professor Huang successfully resolved the jaundice. The client’s yellow complexion gradually faded, and her liver function laboratory results returned to normal range. Yin Chen Hao Tang and Yin Chen Wu Ling San are both used to treat jaundice, but at different stages. Each prescription has its own fang-zheng (formula pattern). To achieve the maximum effect of the prescription, fang-zheng differentiation is key.
