OBJECTIVE
To evaluate the effects of fixed oil of Caryocar coriaceum (FOCC) on the topical inflammation and cutaneous wound healing.
METHODS
FOCC was purchased commercially and used at 6%, 12%, 25%, 50% and 100% on model of ear edema induced by xylene and ointments formulations at 6% and 12% on wound excision model in mice. Skin lesions were evaluated by planimetry and histological analysis.
RESULTS
FOCC was capable of reducing inflammation in a dose-dependent fashion. FOCC in nature (100%) inhibited the ear edema in 38.01% and 39.20% at time 15 min and 1h, respectively, after induction of inflammation, when compared to the positive control. The topical administration of FOCC ointment 12% showed a significantly reduction of unhealed wound area, with increased percentage of wound contraction (96.54%) on day 7 when compared to the other groups. The results of histological evaluation supported the outcome of excision wound model.
CONCLUSIONS
Caryocar coriaceum inhibits the topical inflammation and accelerate cutaneous wound repair.
