The effect of osthole on noxious heat and capsaicin-induced pain. (a) Comparison of tail-flick latencies after immersion into heated water baths (48°C) following oral administration of osthole. Significantly prolonged tail-flick latency at temperature of 48°C in osthole group as compared to control group. The analysis showed that the time spent in licking (b) and the number of flinches (c) were increased at capsaicin-injected hind paw. Oral administration of osthole can reduce the licking time (b) and flinch number (c) induced by capsaicin-injected (con: control group; 10 μL saline was injected intradermally into the heel pad; , , ; n = 6 per group).
