The content of 8 heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) was evaluated in infusions prepared from 13 different herbal compositions commercially available in drug or herbal stores. The mixtures were produced by a Polish manufacturer “Herbapol”. The concentration of heavy metals was determined using flame atomic absorption spectrometry (FAAS). In the herbal infusions Mn was found in the highest concentration varying from 3.03 to 129.01 mg/kg. The element of the lowest content was Cd in the range of 0.024–0.153 mg/kg. According to interquartile ranges the concentrations of studied heavy metals in infusions decreased in the following descending order: Mn>Fe>Zn>Cu>Ni>Cr>Pb>Cd. Cluster analysis allowed for the division of herbal infusions into groups described by comparable levels of heavy metals. In water extracts made from Urosan, Nervosan, Infektoten and Cholagoga, distinctive levels of Mn, Fe and Cr were determined. According to WHO regulations, the concentrations of the elements did not exceed the allowable limits.
