In recent years, it has been tried to overcome drug resistance, especially with the use of herbal products in combination with existing drugs. In this study, we aimed to investigate the effectiveness of eucalyptol in combination with acyclovir. A Vero cell line was used for toxicity tests and viral culture isolation studies in the study. The non-toxic concentrations of eucalyptol and acyclovir were determined by the MTT method. Antiviral efficacy studies were performed within non-toxic concentrations. Antiviral activity was determined by calculating the IC50 values of the compounds against HSV-2. In addition, it was evaluated by the RT-PCR method. The 50% inhibitory concentration (IC50) and Fractional inhibitory concentration (FIC) index values determined during 24 hours and 48 hours of action showed that Eucalyptol exhibited a potent activity. This efficacy was found to be stronger when used in combination with acyclovir. These results show that the combination of Eucalyptol and acyclovir may be beneficial against resistant HSV infections. We suggest that the results of these studies, which are planned as in-vitro, be supported by in-vivo studies. © 2022 Toate drepturile asupra acestei edi?ii sunt rezervate editorilor.eninfo:eu-repo/semantics/openAccessacyclovirantiviralEucalyptolHSV-2synergyConference Object27327810.24264/icams-2022.III.32-s2.0-85153533856N/A
