Comet tails of human foreskin fibroblast cells (HFF3) treated with H2O2 and Achillea extracts. Pre-treatment with the methanol extract of Achillea leaves (1 µg/ml) significantly (p<0.05) reduced comet tail of HFF3 cells induced by H2O2 (500 mM) treatment. Untreated cells (a), H2O2 treated cells (b), H2O2-incubated cells pretreated with Achillea eriophora (c), and A. biebersteinii extracts (d). Arrows indicate comet tails which contain damaged DNA
