Abstract :
Herbs are considered as effective remedies to heal diseases worldwide. As a
result of given increasing trend of air, water and soil pollutions, health and quality
of these herbs have now become a quite serious and important issue to be attention
to. One of the main concerns is the presence of heavy metals in herbal drugs. In this
study, the amount of lead, cadmium, and copper in edible herbal dribbles present in
Iranian drug market have been measured with the aid of a polarography technique,
Differential Pulse Stripping Voltammetry (DPSV). The simultaneous determination
of the target elements was done in samples obtained from herbal drops present in
citywide drugstores was performed. It was observed that the mean values of
measured ions in the samples were beneath WHO and FDA’s standards and the
concentration of cadmium in most samples was beneath the applied technique
detection limit and consequently could not be traced.
