Impact of plant extracts on HSV-2 replication. Cell culture media of HSV-2 infected Vero cells were replaced with medium containing 7.5–0.47 mg/mL of plant extracts. Vero cells were incubated for 24 h, 37 °C, 5%CO₂. At 24 h post-infection, Vero cells were lysed and a direct qPCR was applied to measure the HSV-2 genome concentrations. Data are mean ± SD (n = 3). Statistical comparisons of qPCR Ct values (treated vs. untreated control) were performed by one-way ANOVA analysis corrected by Dunnett’s multiple comparison test. *: p < 0.05. N.D: not done.
