Viral inhibition after treatment with two different concentrations of the highly promising essential oils as measured by plaque reduction assay. The viral reduction in influenza A/H1N1 and A/H5N1 following treatment with the two essential oils were depicted in percentages. Each oil was evaluated independently against both viruses and data were plotted using GraphPad Prism 5.01 software.
