Effect of rosemary extract (RE) on the progress of diabetes-induced thermal hyperalgesia. Lines indicate nociceptive threshold of each experimental group. Values are presented as mean ± standard error of the mean (SEM) of n = 6–8 animal. Asterisks indicate significant difference (*P < 0.05, **P < 0.01, ***P < 0.001) vs. control groups. Hashtag indicates significant difference (#P < 0.05) vs. diabetic group at the same time point
