Cell viability assays of eucalyptus oil and eucalyptol on T24. Cell viability was determined using CCK-8 kit. A Cells were treated by eucalyptol and eucalyptus oil with four different dilutions, for 6 h. B Cells were treated by eucalyptol and eucalyptus oil with 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 times (n = 3) in triplicates. Asterisks indicate p < 0.05 compared to the controls
