Herbal remedies, used for many years for therapeutic purposes, have traditionally been considered safe and effective. Herbal medicine toxicity has been infrequently reported in Spain. We present two cases of acute hepatitis after ingestion of herbal infusions over a period of several months. Among the plants consumed was Teucrium chamaedrys (germander), which has been associated with several cases of hepatotoxicity, mainly in France. After ruling out other causes of hepatitis, we consider that Teucrium chamaedrys provoked the disease. One patient presented acute, cholestatic hepatitis and another presented mixed (hepatocellular and cholestatic) hepatitis. In both patients, the disease was resolved after discontinuing the intake of the herbal teas. We believe that herbal medicine toxicity may be increasing due to the growing consumption of these products. Finally, we emphasize the need to rule out the intake of herbal remedies in patients whose liver tests present abnormalities.
