Means and standard deviations of epithelial lesions obtained from optical microscopy. Means and standard deviations obtained from optical microscopy of histological sections stained by H&E after 24 h of the treatment with essential oil of M. alternifolia or physiological solution for the control group. The number of histological fields with the presence of epithelial lesions was determined for each animal studied (n = 10 per group). *A significant difference between the groups was observed (Student’s t-test, P = 0.005).
