Journal of Medicinal Plants Research 11/2010; 4(21):2256-2263.

ABSTRACT Genus Artemisia is cosmopolitan in distribution and its several species are being used in folk therapeutic treatments worldwide. In this study, elemental compositions of seventeen indigenous species (A. scoparia, A. absinthium, A. indica, A. santolinifolia, A. maritime, A. vulgaris, A. japonica, A. nilagirica, A. herba-alba, A. annua, A. brevifolia, A. moorcroftiana, A. dracunculus, A. roxburghiana and A. dubia) that are commonly used against ailments in Pakistan were studied for the first time through atomic absorption spectrophotometry methods. In this study we observed nine trace elements namely Zn, Cu, Cr, Ni, Co, Cd, Pb, Mn, Fe and four major elements that are K, Na, Ca and Mg in these species. Further it is observed that in few sepses the concentration of heavy metals are found over and above the normal concentration levels than the international safety standards prescribed for medicinal plants. This study also discusses the impacts of heavy metal toxicity in humans.
