In many European countries, including Romania, the statutory regulation of herbal products as medicines has led pharmaceutical companies to orient themselves towards the production of herbal medicines. In this paper we determined the metal content of certain phytochemical products produced by a Romanian company. The medicinal plants are cultivated by the company producing the phytochemicals on large areas and even in organic farming system. An acid-assisted microwave digestion procedure is optimized for the determination of metals in the products analyzed by the use of Inductively Coupled Plasma Optical Emission Spectrometry techniques. Thus, the analysis of the content of six types of capsules determined that they contain a lot of chemicals, metals like calcium, potassium, sodium, magnesium, zinc, strontium, manganese. The analysis also determined that the capsules contain toxic elements (Cd, As, Cr, Mo), but which are present in small quantities, within the toxicity limits stipulated by the law.
