Essential and non-essential heavy metals like Fe, Ni, Mn, Zn, Cu, Co,  Cd, Cr and Pb were analyzed in nine selected medicinal plants namely Persea duthiei, Suaeda monoica, Oxalis corniculata, Hibiscus rosa, Erythrina variegates, Curcuma longa, Berberis lyceum, Zanthoxylum alatum and Quercus dilatata by Atomic Absorption Spectrophotometer. These medicinal plants were selected for our investigation having in mind their extensive use in traditional medicine for various ailments by local physicians in the area from where these plants were collected. In general the concentration level of heavy metals in the selected plants was found to decrease in the order of Fe > Zn > Mn > Cu > Ni > Co > Cr > Cd > Pb. In most plants the concentration of Pb was found below the detection level. The results revealed that the medicinal plants accumulate the elements at different concentration. Monitoring such medicinal plants for heavy metals is a supreme importance in protecting the Public from the adverse effects of these heavy metals.
