Abstract: Objective To provide a roadmap based on modular evidence chains for the clinical diagnosis of herbal induced liver injury (HILI). Methods Four modules of information were investigated, including the temporal relationship between the application of Chinese herbal medicine and the occurrence of liver injury, the related liver toxicity information of the herbals itself, the possibility of drug combination as the cause of liver injury, and the potential non-drug factors of liver injury. All these information were incorporated to form an logistically structured chain of evidence for the diagnosis of HILI. Results and Conclusion The clinical diagnostic principle of HILI is similar to that of liver injury caused by modern drugs (including chemical drugs and biomedicine), but it has its own characteristics and difficulties. After analyzing the variability of temporal relationship between Chinese herbal medicine and liver injury, the following information were detailedly evaluated in multiple dimensions, including the liver toxicity information related to Chinese herbal medicine itself, the corresponding information of concomitant drugs, and the existent status of liver injury caused by other pathogens. Then a revised roadmap based on the evidence chain was proposed. Rousse Uclaf Causality Assessment Method (RUCAM) scale is advisable in the diagnosis of HILI, yet the diagnostic value of Revised Electronic Causality Assessment Method (RECAM) scale for HILI needs to be further investigated in real world clinic. If necessary, the diagnosis of HILI should be further confirmed with the Structured Expert Opinion Progress (SEOP). Some pathological features of liver biopsy may be helpful for the confirmation of HILI, and specific biomarkers of HILI need to be further explored.
