MANZOOR IQBAL
KHATTAK1* AND MAHMOOD IQBAL KHATTAK2
Abstract: The paper
presents heavy trace metals analysis in some widely used medicinal-
herbal plants of Pakistan by using Inductively Coupled Plasma. Because
these commonly used medicinal- herbal plants from Pakistan are being
specifically utilized for the treatment of various diseases, so samples
of medicinal-herbal plants were collected from open market and from the
fields. Collected samples were digested and analyzed for their
nutritional trace metals (Pb, Cd, Fe, Zn, Ni, Cu & Mn) composition and
then the results obtained were compared to international and national
standards as required by World Health Organizations. The deficiency or
excess of the samples for essential trace metals are reported.
