RESULTS: The IC50 values, determined by plaque reduction assay, were 2.4 and 4.1 microg/ml for HSV-1 and HSV-2, respectively, while the cytotoxicity assay against Vero cells, as determined by the MTT reduction method, showed a CC50 value of 132 microg/ml, indicating a CC50/IC50 ratio of 55 for HSV-1 and 32.2 for HSV-2. Cells (5 × 105) in 100 μl were exposed to PR8 at an MOI of 50, and incubated at 4°C for 30 minutes to allow virus binding. The stained monolayers were then washed and plaque diameter was measured with a digital caliper (Mitutoyo, Japan). Even though essential oils from Z.
