Impact of carvacrol, thymol, and their combination on the viability of the KG1 myeloid leukemic cells. Flow cytometric analysis of cell death with Annexin V-FITC/PI double staining after 24 h and 48 h treatment with different concentrations of carvacrol and thymol (individually or in combination). Data represent the mean ± SEM of three independent experiments relative to vehicle. The levels of statistical significance were p < 0.05 (*), p < 0.01 (**), p < 0.001 (***), and p < 0.0001 (****).
