This study was aimed to observe the effect of gold buckwheat fermented tea on both acute and chronic inflammation in mice. Ear swelling was induced by xylene. Toe swelling was induced by carrageenan. The acute inflammation model was induced by the increasing of capillary permeability in the abdomen of mice by acetic acid. The chronic inflammation model of granuloma was used in the evaluation of anti-inflammatory function of gold buckwheat fermented tea. The results showed that the gold buckwheat fermented tea can obviously decrease the rate of xylene-induced ear swelling and the degree of carrageenan-induced toe swelling in mice. And the gold buckwheat fermented tea had antagonism effect on acute inflammation caused by acetic acid through the increasing of capillary permeability in abdomen of mice. Furthermore, the gold buckwheat fermented tea had obvious inhibition effects on proliferation of granuloma in chronic inflammation. It was concluded that the gold buckwheat fermented tea had the prevention and treatment effect on both acute and chronic inflammation.
