Objective The present study evaluated the antinociceptive activity of Calendula officinalis L.(Ca)cream on inflammatory *** Creams with different Ca concentrations were tested for their ability to ameliorate pain-related behavior and edema in rats using formalin test,carrageenan(Cg)-induced acute inflammation model,bradykinin(BK)-induced acute inflammation model,and complete Freund’s adjuvant(CFA)-induced chronic inflammation *** the formalin test,we also examined the implication of peripheral opioid receptors in the antinociceptive mechanisms of Ca cream,by means of Q-naloxone,a peripherally acting nonselective opioid ***,the effects of Ca cream compared with diclofenac on BK-induced edema were examined when the kininase II in tissue was preserved or inhibited by *** local production of redox biomarkers in formalin model,tumor necrosis factor-α(TNF-α)in Cg model and histopathological changes in CFA model were also *** A single application of Ca cream at a dose of 10%or 30%(w/w)decreased the formalin-induced licking/biting behavior during both phases of this test in a Q-naloxone-sensitive *** effect was associated with the reduction of oxidative stress in the injured paw and the edema associated with the later phase of formalin-induced pain.A single application of Ca cream(10%or 30%)reduced paw edema and thermal hypernociception in Cg-induced acute inflammation,corresponding with a local decrease in TNF-α.Ca cream also inhibited BK-induced spontaneous nociceptive behavior and paw inflammation in both paradigms *** applications of Ca cream also decreased CFA-induced chronic inflammation,mechanical hypernociception and histopathological changes in the *** These results reveal the topical antinociceptive and antiedematogenic effects of Ca cream.A modulatory action on peripheral opioid receptors associated with its antioxidant mechanism may be involved,at least in par
