Screening of olive extracts. Co-treatment assay: cells were treated with each extract (200 μg/mL) and infected with HSV-1 at the same time. Negative control (−) indicates infected but non-treated cells, whereas positive control (+) refers to Greco grape cane extract at 10 μg/mL [7]. Statistical analyses were determined by ANOVA with Dunnett’s test for multiple comparisons. Significances are referred to as the negative control (−). **** p < 0.0001; * p < 0.021.
