The knowledge on the concentrations of trace metals is important for determining the effectiveness of the plants in treating various diseases. In this study, the concentration of trace metals in herbal medicine sold in Abakaliki metropolis was determined using varian spectra AA۵۵B atomic absorption Spectrophotometer. The results obtained from the sample gotten from the international market showed that sample A ranged from ۰.۳±۰.۰۶ Cu to ۷.۱۵±۰.۱۴۵ Fe. Sample B ranged from ۰.۹±۰.۰۱۸ Cd to ۵.۸±۰.۱۱۶ Fe, while sample C, D, E, and F ranges from ۰.۷۵±۰.۰۱۵ Cd to ۲۴.۱±۰.۴۸۲ Fe, ۵.۶۵±۰.۱۱۳ Cd to ۱۵.۴±۰.۳۰۸ Fe, ۱.۲±۰.۰۲۴ Cd to ۱۸.۲±۰.۳۶۴ Fe, and ۰.۱۵±۰.۰۱ Cd to ۵.۲±۰.۱۱۲ Fe, respectively. Among all the studied samples, Fe has the highest concentrations. The Fe concentration in samples C, D, and E were above the permissible limit of W.H.O, while the Zn concentrations were within the acceptable limit of W.H.O. The Cd concentrations in the samples were above the standard limit except sample F. The Zn concentrations in all the studied samples fell within the acceptable limit of WHO. From kpirikpiri sample, the obtained results showed that the Cd concentrations of all the samples studied were within the acceptable limit of WHO except in samples A, B,C, and D which ranged from ۰.۱±۰.۰۱ sample F to ۱.۳±۰.۰۲ sample A.
