For the majority of the world population medicinal plants represent the primary source of the health care. Therefore determining the content of heavy metals, accumulated in medicinal plants, is of high importance. Thus, the purpose of this research was to evaluate the content of heavy metals and two metalloids in selected medicinal plants (Matricaria chamomilla L., Melissa officinalis L., Mentha piperita L. and Foeniculum vulgare Mill.), that are traditionally used in alternative medicine. The plant materials were collected in a highly industrialized town (Pancevo). Plant analyses were done according to ICP methodology. The obtained results show that the contents of the potentially toxic elements in the investigated medicinal plant species were below the recommended limits and those medicinal plants from the studied growing site are suitable for preparation of teas and medicinal extracts.
