INTRODUCTION

The growing popularity of traditional herbal dietary supplements (HDS) has prompted discussions regarding their potential association with liver injury,currently named Herb Induced Liver Injury (HILI).A case study reported by Thakralet al[1] published in theWorld Journal of Hepatologyhighlights a distinctive occurrence of autoimmune hepatitis induced by Skullcap supplements.This specific case underscores the significance of identifying potential adverse events associated with the utilization of HDS,particularly considering the rising prevalence of their use among the general population.

The reported case involves a middle-aged woman with no prior health issues,who developed sudden jaundice after four months of consuming Skullcap mushroom supplements.The case report indicates that despite testing negative for multiple chronic liver diseases,the first liver biopsy detected severe drug-induced liver injury in resolution.The patient's condition worsened,leading to a subsequent diagnosis of autoimmune hepatitis,with a positive response to discontinuation of the supplement.

In parallel,a comprehensive systematic review and meta-analysis by Ballotinet al[2] aimed to identify herbal products associated with HILI.The study,published in the World Journal of Clinical Cases,analyzed 936 cases reported in 446 references,identifying 79 types of herbs related to HILI.Skullcap-induced HILI typically manifested in individuals using the dried leaves and stems of Scutellaria spp.for various purposes,including the treatment of anxiety,stress,and insomnia.The onset of symptoms and jaundice occurred within one week to three months,with a pattern of typically hepatocellular liver injury,with a few cases of mixed hepatocellular and cholestatic liver injury.The dose that was ingested varied greatly Skullcap,ranging from 400 mg to 16 g daily.Skullcap-induced HLI was more prevalent among females and the mean age was 54 years-old.Common symptoms encompass nausea and choluria,with affected patients frequently reporting osteoarthritis and hypertension.Generally,HILI induced by Skullcap exhibits mild-to-moderate severity,resolving promptly upon discontinuation of the herb.This cessation typically results in the normalization of liver function tests within a period of 12 wk.However,in the systematic review by Ballotinet al[2] reveals a considerable mortality rate of 14.2% was described,and in some severe cases,liver transplantation was necessary,potentially influenced by publication bias favoring the reporting of more severe outcomes.

Both studies underscore the generally positive prognosis of HILI following discontinuation of the implicated herbal product.However,they also elucidate the potential for severity,emphasizing the need for vigilant monitoring and intervention.This severity is reflected in a significant mortality rate associated with Skullcap-induced HILI.

CONCLUSION

In summary,there is an urgent need for increased awareness concerning the potential hepatotoxic effects of herbal supplements,with a specific focus on Skullcap.These cases emphasize the critical importance of recognizing and comprehending the patterns and outcomes linked to Skullcap-induced liver injury and other forms of HILI.As the usage of herbal supplements continues to escalate,fostering collaboration between clinicians and researchers becomes imperative to unravel the intricate nature of herb-induced liver injuries and guarantee the safe utilization of these products.
