Concentration of Cd, Cr, Ni, and Pb were determined in peppermint leaves (Folium Menthae piperitae), chamomile blossom (Anthodium Chamomillae), and their infusions by atomic absorption spectrometry (AAS) after microwave digestion of plants samples. Peppermint and chamomile preparations by five different producers were purchased at various pharmacies in Poland. Infusions were made from herbs according to prescription for patients, provided by the producer of medicine on the package. Results show that in exam of medicinal plants the content of cadmium exceeds World Health Organization (WHO) standards. The highest level of extraction was observed for Ni (50-70% of the total content in herb), Cr (28-36%), Cd (14-16%), and the lowest for Pb (about 6%). The calculated daily intake all analyzed elements was very low. Phytotherapy with using of these herbs is safe for health of patient even in case of long time therapy.
采用微波消解植物样品后，通过原子吸收光谱法（AAS）测定薄荷叶（Folium Menthae piperitae）、甘菊花朵（Anthodium Chamomillae）及其浸液中的 Cd、Cr、Ni 和 Pb 浓度。从波兰不同药店购买了由五家不同生产商生产的薄荷和甘菊制剂。浸液是根据药品生产商在包装上提供的给患者的处方用草药制成的。结果表明，在对药用植物的检查中，镉含量超过世界卫生组织（WHO）标准。Ni（草药中总含量的 50-70%）、Cr（28-36%）、Cd（14-16%）的提取水平最高，Pb（约 6%）的提取水平最低。所有分析元素的计算日摄入量都非常低。即使在长时间治疗的情况下，使用这些草药的植物疗法对患者的健康也是安全的。
