- Crosses denote the magnitude of the antibacterial activity; the numbers in brackets are the P values obtained from t tests comparing the size of the halos produced with the essential oils with those produced by grapeseed oil for the disc diffusion and zone of clearance assays, and from comparing the A600 of the turbidometric assay in the presence of essential oil after 6 hours with that lacking essential oil.
