Herb-induced Liver Injury in Asia and Current Role of RUCAM for Causality Assessment in 11,160 Published Cases

Open access
Teschke, Rolf, Zhu, Yun, Jing, Jing·2020·Journal of Clinical and Translational Hepatology

Abstract

Herb-induced liver injuries (HILI) by traditional herbal medicines are particular challenges in Asian countries, with issues over the best approach to establish causality. The aim of the current analysis was to provide an overview on how causality was assessed in HILI cases from Asian countries and whether the Roussel Uclaf Causality Assessment Method (RUCAM) was the preferred diagnostic algorithm, as shown before in worldwide evaluated cases of drug-induced liver injury (DILI). Using the PubMed database, publications in English language were preferred to allow for reevaluation by peers. Overall 11,160 HILI cases have assessed causality using RUCAM and were published by first authors working in Asian countries. With 21 evaluable reports, most publications came from mainland China, with Hong Kong and Taiwan, followed by Korea (n=15), Singapore (n=2), and Japan (n=1), while other Asian countries were not contributory. Most publications provided case and RUCAM data of good quality. For better presentation of future cases, however, the following recommendations are given: (1) preference of prospective study design with use of the updated RUCAM version; (2) clear separation of HILI cohorts from those of other herbal products or DILI; (3) case series for epidemiology studies should contain many essential data, possibly also as supplementary material; (4) otherwise, preference of single case reports providing individual case data and RUCAM-based causality gradings, and applying liver test threshold values; and (5) publication in English language journals. In conclusion, China and Korea are top in presenting RUCAM-based HILI cases, other Asian countries are encouraged to follow.

TL;DR

This review analyzes 11,160 published herb-induced liver injury (HILI) cases from Asian first authors whose causality was assessed with RUCAM, finding China and Korea dominant and other Asian countries largely absent. It argues that RUCAM is the preferred causality method and recommends prospective designs, updated RUCAM, clear separation of HILI from DILI, complete case data, and liver-test thresholds.

Key findings

  • Across Asian publications, 11,160 HILI cases had causality assessed using RUCAM; China contributed 21 evaluable reports, Korea 15 reports covering 526 HILI cases, Singapore 2 reports covering 25 HILI cases, and Japan 1 report, while other Asian countries were “not contributory.”
  • China and Korea are described as top in presenting RUCAM-based HILI cases; China’s reports included large series such as 6,971 HILI cases in Shen et al. and 1,552 HILI cases in Chow et al., while Korea’s reports included 149 HILI cases in Suk et al. and 97 in Lee et al.
  • RUCAM grading is defined as ≤0 excluded, 1–2 unlikely, 3–5 possible, 6–8 probable, and ≥9 highly probable; the paper stresses that “definitive” is not a RUCAM category, despite some publications using it erroneously.
  • The paper recommends prospective study design with the updated RUCAM, separation of HILI cohorts from DILI or other herbal products, complete case data, individual RUCAM gradings, ALT ≥5×ULN and ALP ≥2×ULN thresholds, and English-language publication.

Methods

  • PubMed was searched from 1964 to December 30, 2019, using terms including herb-induced liver injury, HILI, RUCAM, Roussel Uclaf Causality Assessment Method, and Asian country names, alone or in combination; the search was mostly confined to English-language reports.
  • Publications by Asian authors on HILI cases assessed for causality using RUCAM were individually evaluated for quality of reported RUCAM data; the final compilation included original papers, consensus reports, and review articles.
  • The analysis is a narrative review and tabular compilation, not a formal systematic review or meta-analysis; Table 1 lists selected published HILI cases assessed by RUCAM, occasionally together with DILI cases.

Limitations

  • Stated: the search was mostly limited to English-language publications, so reports in local languages may have been missed; RUCAM is not designed for chronic DILI/HILI or for injury occurring on pre-existing liver disease; poor case data or incorrect user application can produce invalid RUCAM gradings.
  • Stated: many included reports were retrospective, which commonly yields low RUCAM scores and low causality gradings; valid HILI epidemiology data are not available for China, and other Asian countries had virtually no valid RUCAM-based HILI reports.
  • Evident from the text: this is a narrative review with selected “most relevant” publications rather than a PRISMA-style systematic search, and the authors advocate strongly for RUCAM over other causality methods, which may shape interpretation of study quality and grading.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Suk's score range includes a highly probable score

    Minor

    The stated range reaches 12, which the paper's grading rules classify as highly probable, not merely possible or probable.

  • The Zhang case fraction conflicts with Table 1

    Minor

    The text describes 26/28 cases as highly probable, whereas Table 1 says there were 54 cases: 26 highly probable and 28 probable.

  • Scores above five cannot receive a possible grading

    Minor

    The Gao row says all included scores exceeded five yet describes some as possibly graded and reports a mean score of 5.52. The paper's own scoring rules place possible at 3-5; its worksheet assigns integer scores, so a mean of 5.52 is also below the minimum for a group whose scores all exceed five.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
