Although medicinal plants may be produced in polluted soil or water settings, their extracts have long been utilized to treat illnesses affecting the general populace. Many of these herbs are collected and prepared in an unsanitary way by untrained local natural healers and other sellers. As a result, there is a chance that potentially harmful elements from the environment will contaminate the area. In this study, the five most prevalent poisonous heavy metals (arsenic, cadmium, chromium, lead, and mercury) were measured in five medicinal plants used extensively in southwest Ethiopia's Sheka Zone., including Bersama abyssinica, Calpurnia aurea, Croton macrostachyus, Eucalyptus globules, and Solanum incanum. The Tepi district in southwest Ethiopia provided the plant samples, which were then cleaned, dried, disinfected with 0.1% HgCl, digested with 69% HNO3 and 35% H2O2, and then subjected to AAS analysis. According to the study's findings, neither cadmium nor mercury was found in Solanum incanum. Additionally, Bersama abyssinica and Croton macrostachyus also do not contain mercury. Cd (below detection limit (BDL) to 0.6012 ppm), As (below detection limit (BDL) to 0.032 ppm), Hg (below detection limit (BDL) to 0.020 ppm), Cr (0.75 0.18 to 1.32 0.21), and Pb (below detection limit (BDL) to 0.0200 ppm) were the harmful heavy metals with the widest concentration ranges (0.01013 ppm to 0.4012 ppm). The findings demonstrate that while these plant species were below the WHO permitted limits for consumed therapeutic herbs; their usage for disease prevention will not cause heavy metal toxicity and may even be advantageous to users who are deficient in micronutrients.
