AC, aberrant crypts; ACF, Aberrant Crypt Foci; GI, control group; GII, experimental group with DMH induction; GIII, experimental group with DMH induction + essential oil; GIV, experimental group with DMH + 5-FU induction; GV, experimental group with essential oil. Results expressed as average of the quantities observed in the animals of the same group ± standard deviation. ^a, Significant when compared to GII; ^b, Significant when compared to GIV. Significance when p<0.05.
