Local anti-inflammatory activity: Topical formulation containing Kalanchoe brasiliensis and Kalanchoe pinnata leaf...

Kalanchoe brasiliensis and Kalanchoe pinnata are used interchangeably in traditional medicine in the treatment of wound healing. In this context, the objective of the present study was to evaluate the local anti-inflammatory activity of a topical formulation containing aqueous extract of both species. The in vivo model used was ear edema induced by croton oil and paw edema induced by carrageenan. The Swiss mice treatments use formulations containing aqueous extract at different concentrations (1.25%, 2.5%, and 5%) or dexamethasone (1 mg/g), all administered topically and immediately after edema induction. The treatment with formulations containing aqueous extract of both species reduced ear and paw edema, besides that, the decrease in edema was evidenced by reduction of myeloperoxidase activity, IL-1β, and TNF-α levels and increase IL-10 levels. In conclusion, the two species showed local anti-inflammatory activity; however K. brasiliensis showed a better result in both edematogenic models since it had activity in the lowest concentration.
