dc.description.abstractThe present study aimed at evaluating the elemental composition and daily dose standardization based on heavy metal presence in Tosign leaves (Thyme schemperi). Flame Atomic Absorption Spectroscopy were performed to analyze the presence of the heavy metals : copper, chromium, cadmium, lead and zinc. The mean contents of the selected heavy metals were determined from triplicate samples of thyme schemperi collected from Bale Goba In this study the concentration of heavy metals obtained inTosign leaves samples in mg/L were cadmium (0.018± 0.003), copper (0.188±0.002), lead (0.375± 0.009), zinc (0.853±0.051) and chromium (BDL). The concentration of Cd, Cu, Pb and Zn were below the maximum allowable concentration for medicinal plants given by WHO. Therefore, they were safe for health risk.
