Figure 2. Effects of the essential oil of Croton zehntneri (EOCz) on thermal nociception in mice submitted to the hot-plate test. Abscissa, time (min) after oral administration of EOCz. Ordinate, latency (s) for the response to thermal stimulation (50 ± 0.5oC). Data are reported as means ± SEM (N = 10) for each EOCz dose. *P<0.05 compared to control at a given time (ANOVA, Dunn's test).
