Background and Aims: The levels of cadmium (Cd) and lead (Pb) were analyzed in frequently used herbs including ginger, liquorice, nutmeg and turmeric in Turkey. Materials and Methods: The levels of Cd and Pb in commonly used herbs were analyzed by inductively coupled plasma optical emission spectrometry after a closed microwave-assisted digestion. Results: The concentration ranges for the Cd and Pb were found to be 0.25-0.78 mg/kg and 3.04-6.45 mg/kg, respectively. While Pb levels were below the maximum permissible limits, high Cd levels were detected in herbs which would not pose any health risk for consumers regarding an exposure assessment. Conclusion: It is important to implement regular monitoring of heavy metal content in herbs, including medicinal plants, to assess their potential risks to human health in consideration of the potential for multiple exposure via other sources.
