A new health advisory warns that some widely used herbal supplements can harm the liver, especially among older adults who take them for joint pain or general well-being. While these products are marketed as natural solutions, they can provoke serious liver reactions that may progress to liver failure in rare cases.
The JAMA Network Open study from 2024 identifies six botanicals most often linked to liver toxicity: Ashwagandha, Black Cohosh, Garcinia Cambogia, Green Tea Extract, Red Yeast Rice, and Turmeric/Curcumin. The research notes that middle-aged and older adults are particularly at risk because aging can alter how the liver processes substances, increasing susceptibility to adverse effects.
The findings matter for Thailand, where many consumers seek dietary supplements alongside traditional remedies. Data from the study indicate that millions in the United States have used botanicals with potential liver risks, illustrating a broader global concern. Health experts emphasize that even natural compounds require liver processing, and interactions with other medications or age-related changes can complicate safety.
Regulatory practices around supplements differ from those for prescription medicines, often resulting in less stringent oversight. Mislabeling and undisclosed ingredients remain ongoing issues in the global market, underscoring the importance of cautious consumption and informed choices. Research from reputable health institutions shows that some products may contain substances that influence liver health without clear labeling.
Thai consumers should take practical steps to stay safe:
- Research thoroughly using trusted sources and medical databases to assess safety.
- Consult healthcare providers before starting any new supplement, especially if liver issues are a concern or if other medications are used.
- Choose reputable brands and be wary of concentrated botanical blends.
- Prefer products with third-party testing to ensure label accuracy and absence of contaminants.
- Avoid supplements marketed specifically for liver health without solid evidence; prioritize a balanced diet and healthy lifestyle.
- Include routine liver function tests in regular health checkups to catch early signs of stress or damage.
Thailand’s rich tradition of herbal and traditional remedies continues to shape health practices. Balancing cultural heritage with evidence-based medicine is essential, particularly for older adults who may be more vulnerable to adverse effects.
Public health authorities advocate heightened awareness and careful decision-making. By promoting informed conversations with clinicians and relying on credible information, Thailand can protect liver health while honoring cultural practices.
