In this study, the concentration of 10 elements was measured by the method of instrumental neutron activation analysis (INAA) in two types of medicinal plants as Stachys lavandulifolia and Hymenocrater. Samples were taken from various parts of the cities of Arak and Sarband, as well as from the Alvand zone Hamadan in Iran. This study shows that these plants are rich in magnesium, manganese, zinc, calcium and iron.
