A Rare Case of Tongkat Ali-Induced Liver Injury: A Case Report

Drug-induced liver injury (DILI) presents a significant challenge in clinical practice, particularly with the rising popularity of herbal and dietary supplements (HDS) in the United States. Tongkat Ali (Eurycoma longifolia Jack), a Southeast Asian herb, has garnered attention for its purported health benefits, including enhancing testosterone levels. Here, we present a case of a 47-year-old male with acute liver injury following Tongkat Ali use, the first reported case of its kind in the literature. The patient exhibited worsening scleral icterus, elevated liver enzymes, and jaundice shortly after initiating Tongkat Ali supplementation, prompting hospitalization and subsequent clinical improvement upon discontinuation of the supplement. Differential diagnosis and exclusion of other etiologies were essential in establishing the causal link between Tongkat Ali consumption and liver damage, underscoring the difficulty in diagnosing HDS-induced liver injury. The rise in DILI cases parallels the expanding use of nutraceuticals, necessitating vigilance among healthcare professionals. While mechanisms of herbal-induced liver injury remain unclear, genetic predisposition and metabolic factors may be implicated. This case emphasizes the importance of heightened awareness among healthcare providers regarding the potential hepatotoxic effects of herbal supplements, particularly in individuals consuming multiple agents. Further research into the safety profile and mechanisms of Tongkat Ali-induced liver injury is warranted to inform clinical management and promote safer supplement use.
