Figure 7

Topical anti-inflammatory activity of babassu oil and microemulsion in PMA-induced ear edema. Results are expressed as the mean ± SEM and analyzed by ANOVA followed by Tukey’s test with set at 0.05. Different letters show statistical differences between groups (). (−) Negative control (acetone); (V) microemulsion vehicle (48.8% surfactants, 39% aqueous phase, and 12.2% water); babassu oil (μL/ear); (ME) babassu microemulsion (μL/ear); and (Dexa) dexamethasone (mg/ear).
