Serious Multiorgan Toxicity Caused by Mixed Herbal Tea Ingestion: A Case Report

Recent years have witnessed a growing trend in the use of complementary and alternative herbal products. However, the ingestion of some herbal products may cause a wide spectrum of adverse effects. We report a case of multiorgan toxicity following the ingestion of mixed herbal tea. A 41-year-old woman presented to the nephrology clinic with complaints of nausea, vomiting, vaginal bleeding, and anuria. She had consumed a glass of mixed herbal tea three times a day after meals for three days, to lose weight. Initial clinical and laboratory findings showed serious multiorgan toxicity including hepatotoxicity, bone marrow toxicity, and nephrotoxicity. Although herbal preparations are marketed as natural products, they may cause various toxic effects. There should more efforts to raise public awareness about the possible toxic effects of herbal preparations. Clinicians should consider the ingestion of herbal remedies as an etiology when encountering patients with unexplained organ dysfunctions.
