From:  Aloysia citrodora extract as a chemopreventive agent against HPV16-induced lesions: findings from K14-HPV16 mice

Mean values of the genetic damage index (GDI) in the blood, measured by the alkaline comet assay (mean ± standard deviation). Treatment without formamidopyrimidine DNA glycosylase (Fpg) treatment (GDI) is shown in white and treatment with Fpg (GDIFpg) is shown in black. G1 are wild-type (WT) mice that drink water; G2 are mice with human papillomavirus (HPV) that drank water; G3 are WT that drank daily an aqueous extract of Aloysia citrodora at a concentration of 0.013 g/mL; G4 are mice with HPV that drank daily an aqueous extract of A. citrodora at a concentration of 0.006 g/mL; G5 are mice with HPV that drank daily an aqueous extract of A. citrodora at a concentration of 0.008 g/mL; G6 are mice with HPV that drank daily an aqueous extract of A. citrodora at a concentration of 0.013 g/mL
