Cell viability assays of lavender EOs and linalool on T24 cells. Viability of the cells were determined using CCK-8 kit. A Cells were treated by linalool and lavender EOs prepared at the beginning of flowering and the end of flowering period with four different dilutions, for 6 h. B Cells were treated by linalool and lavender EOs prepared at the beginning of flowering and the end of flowering period using four different dilutions, for 24 h. Control cells were treated with the same dilutions of DMSO for 6 h or 24 h. The experiments were repeated three (n = 3) times in triplicates. Asterisks indicate p < 0.05 compared to the controls
