Methanol Extract of (Lam.) Ding Hou Leaves Inhibits Carrageenan- and Formalin-Induced Paw Edema in Mice.

Inflammation is a physiological condition that when unattended causes serious health concerns over the long term. Several phytocompounds have emerged as promising sources of anti-inflammatory agents. is a traditional medicine for inflammatory and toxicity insults; however, this has not been scientifically confirmed. The purpose of this study is to evaluate the anti-inflammatory properties of methanol leaf extract in a mouse model. This study investigates the anti-inflammatory activities of a plant extract obtained from leaves of (TSE) with a focus on carrageenan- and formalin-induced paw oedema in mice. The extract's efficacy was assessed using well-established inflammation models, and the results showed a considerable reduction in paw edema in both cases. In the case of carrageenan model TSE at 50 mg/kg showed a 53.0 ± 2.5% reduction in edema, while those treated with TSM at 100 mg/kg exhibited a 60.0 ± 1.8% reduction ( < 0.01). In the case of a formalin model when a higher dose of TSE (100 mg/kg) was given, paw thickness decreased by 47.04 ± 1.9% on the fifth day and by 64.72 ± 2.2% on the tenth day. LC-MS analysis reported the presence of gallic acid, quinic acid, quercetin, clitorin, myricitrin, retronecine, batatasin II, gingerol, and coumaric acid in the extract. Overall, this study confirms that extract exerts anti-inflammatory effects in animals and is possibly mediated through the combined effects of these phytochemicals.
