Marek Wesolowski and Pawel Konieczynski

The concentrations of total nitrogen, phosphorus, sulfur and chlorine in commercial raw plant materials used in medicine taken from species growing in Poland, were determined.

Species of medicinal plants, which have the highest and the lowest concentrations of the elements were identified. It was also proved, that there are some relations between levels of particular non-metals among herbs and leaves,"•
