Herbal medicines can cause liver damage (hepatotoxicity), with risks increasing due to undisclosed use and interactions with other drugs. Awareness of these adverse effects and better monitoring are crucial for patient safety.

Area of Science:

  • Hepatology
  • Pharmacology
  • Toxicology

Background:

  • Herbal medicine use is rising, leading to increased recognition of herbal hepatotoxicity.
  • Potential benefits of herbal products for liver disease are largely unproven, necessitating awareness of adverse effects.
  • Undisclosed herbal use can delay diagnosis and worsen liver injury.

Purpose of the Study:

  • To review emerging herbal hepatotoxins and patterns of liver injury.
  • To identify potential risk factors for herbal hepatotoxicity.
  • To examine herb-drug interactions and their impact on conventional therapies.

Main Methods:

  • Literature review of emerging hepatotoxins and liver injury patterns.
  • Analysis of risk factors, including female gender and cytochrome P450 enzyme induction.

  • Investigation of herb-drug interactions with conventional medications.

    • Main Results:

    • Herbal hepatotoxicity presents with a wide spectrum of liver injury, from transaminase elevations to acute liver failure.
    • Female gender and concomitant use of CYP450-inducing agents may increase susceptibility.
    • Herb-drug interactions can compromise the efficacy and safety of concurrent medical treatments.

    Conclusions:

    • Enhanced awareness of herbal hepatotoxicity and its risk factors is essential.
    • Improved reporting and regulatory systems are needed to monitor herbal toxicity.
    • Further scientific evaluation of phytotherapy's benefits and risks is required.
