Background: Wound healing is among the frequent illnesses that affects the skin, and therefore, the screening of natural preparation to treat skin burn is important. In Morocco, Cynara humilis is a Moroccan medicinal plant widely used for the treatment of skin burn. Objectives: The aim of this study was to investigate the safety of C. humilis and its wound healing potential against skin burn. Methods: In this work, C. humilis was selected based on an ethnopharmacological survey. As revealed by traditional medicine, C. humilis powder extract (CHPE) was used to test wound healing effects. Furthermore, to assure the safety of this powder, acute and subchronic dermal toxicities were investigated on animal models. Results: The oral acute toxicity test of CHPE did not show mortality in treated rats (LD50>2000 mg/kg). Moreover, in the acute dermal toxicity, CHPE at 5 g/kg did not induce clinical signs observed during the observation period of 48 h. In the subchronic toxicity test, CHPE did not cause significant abnormalities in the physiological parameters and pathological changes in the major organs of the rats. Body weight evolution and macroscopic analysis of skin burn showed CHPE exhibited important wound healing effects in a time‐dependent manner. CHPE reduced significantly wound surface (6.93 ± 0.25 cm2) compared with the SDA group (8.30 ± 0.37 cm2) and the no‐treated group (10.05 ± 0.28 cm2). Moreover, the retention rate was increased importantly after the treatment with CHPE (61.66 ± 1.42%) compared with the SDA‐treated group (53.57% ± 2.83%) and the no‐treated group control animals (43.34% ± 1.27%). Conclusion: These results were confirmed by a histological evaluation, which showed that CHPE increased the neovascularization, the collagen deposition, and the re‐epithelialization. The findings of this work suggest that CHPE could be a promising source for developing drugs against skin burn. [ABSTRACT FROM AUTHOR] |
