Comparison of the inhibitory effect of fisetin, kaempferol, luteolin, myricetin, quercetin (4.3 mg per rat=1000 mg per human) and aspirin (ASA; 1.22 mg per rat; 325 mg per human), administered i.p. 10 min prior to niacin on the ear temperature increase recorded 45 min after a single i.p. dose of niacin (7.5 mg per rat) in olive oil (n=6, ^*P=0.0204; ^**P=0.0041; ^***P=0.0002; ^****P=0.0193). The percentage inhibition was calculated after the corresponding baseline temperature was subtracted.
