Antigenotoxic properties of essential oils of H. officinalis subsp. aristatus (1EO–6EO) against DNA damage in human peripheral blood leukocytes, induced by H2O2 in post-treatment protocol. Bars represent the mean value of cells with DNA damage ± standard error of the mean (SEM) versus control treated with H2O2 (n = 3). PBS: phosphate-buffered saline solution. * p < 0.01, ** p < 0.001, *** p < 0.0001.
