Determination of MIC The MIC values of herb extracts are shown in Table 2. In general, there was a significant correlation between the findings for the swab paper disc method and the MIC
determination assay. Based on MIC values, 4, 6, and 8 extracts were declared to have strong (MIC values ≤125 μg/mL), moderate (MIC values of 250 μg/mL), and weak (MIC values ≥500 μg/mL) inhibitory activity, respectively.
