This research is focused on enhancing our plant heritage, emphasizing the need to exploit it effectively. Specifically chose the medicinal plant Cistus salviifolius for our study, where we determined the concentration of seven heavy metals (Zinc, Copper, iron, Lead, nickel, manganese, and cobalt) using flame atomic absorption spectrometry (FAAS). The results from our phytochemical tests revealed a rich presence of secondary compounds, such as flavonoids, tannins, saponins, alkaloids, phytosterols, terpenoids, and phenolic compounds. Heavy metal analysis indicated that Cistus salviifolius contained certain heavy metals detected in traditional prescription extracts, including nickel, copper, iron, manganese, and zinc 3.03, 13.15, 387.33, 1.52 and 5.43 µg/g , all of which fell within the safe limits established by WHO/FAO ( 20-99 )µg/g . In contrast, heavy metal analysis of the acid digest extract of Cistus salviifolius showed levels of copper, zinc, nickel, manganese 6.52 µg/g and cobalt1.13 µg/g that were within the safe limits set by WHO/FAO. However, it is important to note that lead and iron were found to exceed the safe limits,(Iron 476 µg/g) ( Lead 7.86 µg/g) raising concerns about potential health risks associated with these contaminants in this medicinal plant. These findings highlight both the therapeutic potential of Cistus salviifolius as well as the necessity for careful monitoring of heavy metal contamination to ensure safety in traditional medicinal applications. This study Objectives to determine the concentrations of selected heavy metals in Cistus salviifolius using Flame Atomic Absorption Spectrometry (FAAS) through two main sample preparation approaches.............
