Cell viability of NCTC cells cultured with different concentrations of A. montana L. and A. absinthium L. extracts, analyzed by Neutral red (A) and LDH (B) assays. The negative control was represented by cells cultivated in culture plate, in MEM (dotted) and the positive control was represented by cells cultivated in MEM containing 100 μM H₂O₂ (striped). Results are shown as mean ± SD (n = 6). Pairs of negative control and each sample were analyzed by t-test. Significant differences in each pair are marked with ^#p < 0.05 or ^##p < 0.01.
