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.
