This study included that of some plant extracts on the effectiveness of the hemolysin enzyme from Staphylococcus aureus. This enzyme is considered to be a strong virulence factor that this bacterium possesses as it works on the analysis of red blood cells. Therefore, it has been researched on the use of some plant extracts that work to inhibit efficacy. Lawsonia and Thuja extracts, and a number of concentrations of 20,40,80% were attended. The effect of these extracts on the inhibition of the effectiveness of this enzyme was studied. The study demonstrated that all concentrations had an effect on inhibiting the activity of the enzyme, but the ideal focus for inhibition of efficacy was 80%, after which the effect of Other concentrations are 40 and 20%, respectively.
