Effects of the aqueous extract of CS seeds, DEX and ST on pain responses in formalin test. (A) In initial phase (B) and the late phase of FT, administrating the aqueous extract of CS (125, 250, 500 and 1000 mg/Kg IP), DEX (0.5, 1 and 2 mg/Kg IP) or ST 30 minutes before the FT test decreased the time of licking and climbing foot’s behavior (p < 0.01). Besides, the pretreatment of NAL reversed this effect. Data are expressed as the mean ± S.E.M. *p < 0.01, **p < 0.001 as compared with Cont or VEH groups, # p < 0.01 as compared with CS 1000.
