Note: Values are expressed as mean of three replicates ± SD. Means with different letters (a–c) within a column indicate significant differences (p < 0.05) using Tukey’s honestly significant difference (HSD) test with a confidence interval of 95% or 99%. (LEO—lavender essential oil; SEO—sage essential oil; BEO—basil essential oil).
