Study of heavy metals (Cd, Cu, Ni, Pb & Zn) in some medicinal plant species (Hertia intermedia, Cardaria chalepense, Scorzonera ammophila, Tamarix karelini, Astragalus auganus) at Pishin area in Balochistan, Pakistan (original) (raw)

Numerous plants of Pakistan are well known for their remedial prospective and are traditionally utilized in herbal medicine system across the country. In the present study, for the first time five of the most prevalent commonly used therapeutic plants (Hertia intermedia, Cardaria chalepense, Scorzonera ammophila, Tamaix karelini and Astragalus. auganus) of Pishin area are studied by atomic absorption spectrometry for their heavy element (Cadmium, Copper, Nickel, Lead and Zinc) concentrations (ppm). Furthermore, some significant features of trace metal toxicity are also deliberated. Though various floras amass heavy metals however our studied plants have low heavy metal concentrations according to the standards of international safety for human consumption. Therefore, all these plants of the area are safe to use for medicinal purpose.
