In Vivo Potential Anti-Inflammatory Activity of Extracts from Calendula arvensis (CA) Flowers
Calendula arvensis (CA) had been reported in traditional Moroccan medicine to exhibit its extensive use to treat pain and inflammation. Therefore, the objective of this study was to evaluate the anti‐inflammatory activity of CA flowers. The methanol, aqueous, and hexane extracts (ME, AE, and HE) were investigated for inflammatory effects by using two methods, namely, carrageenan and experimental trauma‐induced hind paw edema in rats and using indomethacin (20 mg/kg body weight) as a standard drug. The results demonstrated that Calendula Arvensis CA extracts had significant anti‐inflammatory activity where the HE at the doses of 300 and 500 mg/kg p.o. (p < 0.001) had the best significant reduction and inhibition of edema with 51.08, 71.33 and 63.38, 67.33% induced by carrageenan and on experimental trauma induced rat paw edema at third hour, respectively, and similar as compared with standard drug indomethacin 20 mg/kg body weight p.o. (p < 0.001). These results indicate that it could be suggested as contributory effects to the use of CA flowers in the management of inflammation and pain conditions.
