From: In vitro antiviral activities of thymol and Limonin against influenza a viruses and SARS-CoV-2

Antiviral activities of the investigated essential oils (EOs) and EOs components. (a) Antiviral effects of the investigated EOs and EOs components against seasonal human influenza A/H1N1 virus; (b) Antiviral effects of Thymol and Limonin against highly pathogenic avian influenza A/H5N1 virus. (c) Anti-coronavirus activity against SARS-CoV-2. By plotting log inhibitor versus normalized response (variable slope) and running non-linear regression analyses using GraphPad Prism 5.01 software, the IC50 of the investigated EOs were determined.
