Abstract: The aim of this paper is to present the accumulation content of toxic heavy metals such as Cd, Zn, Cu, Ni and Pb in the shoots of three plants species (Euphorbia cornigera, Rhazya stricta and Citrullus colocynthis) collected from Turbat (Balochistan). These therapeutic plants play an important role in the traditional medication system that has been existed for several years and continuously provide new and novel remedies to the human beings. Moreover, these medicinal plants are used throughout the world for the purpose of treatment of many diseases and also a significant source of raw material for pharmaceutical and agricultural industries. Further, the various concentrations of heavy metals in medicinal plants was recorded as Pb > Zn > Cd > Cu > Ni. In the present research the results were related with the safety standards recommended by the World Health Organization (WHO).
Key words: Medicinal plants, Heavy metals, Metal toxicity and atomic absorption spectroscopy.
