Tannic acid exhibits anti-inflammatory effects on formalin-induced paw edema model of inflammation in rats

The aim of the study was to determine the relationship between anti-inflammatory effects of the natural polyphenolic compound tannic acid (CAS number: 1401-55-4) and myeloperoxidase (MPO) enzyme activity in paw edema model. Thirty-five female rats were divided into five groups. The paws of rats were injected subcutaneously in the plantar surface with formalin except for the control group. Indomethacin and tannic acid were intraperitoneally...
