Abstract


Aloe littoralis Baker (Asphodelaceae family) is a well known plant in southern parts of Iran. Because of its use in Iranian traditional medicine as a wound-healing agent, the present study was carried out to investigate anti-inflammatory and wound healing activities of this plant in Wistar rats. A. littoralis raw mucilaginous gel (ALRMG) and also two gel formulations prepared from the raw mucilaginous gel were used in this study. Gel formulations (12.5% and 100% v/w Aloe mucilage in a carbomer base) were applied topically (500 mg once daily) for 24 days in the thermal wound model. Also Aloe gel formulation (100%) and ALRMG (500 mg daily) were evaluated in incisional wound model. Carrageenan-induced paw edema was used to assess the anti-inflammatory effect of intraperitoneal injection of ALRMG. In burn wound, ALRMG and Aloe formulated gel (100%) showed significant (P<0.05) healing effect. Topical application of ALMRG and Aloe formulated gel (100%) promoted healing rate of incisional wound. In carrageenan test, ALRMG (2.5 and 5 ml/Kg) revealed significant (P<0.05) anti-inflammatory activity. Results showed that A. littoralis is a potential wound-healing and anti-inflammatory agent in rats. Further studies are needed to find out the mechanism of these biological effects and also the active constituents responsible for the effects.
