| Abstrakt: | Objectives: Continuous and excessive secretion of pro-inflammatory and anti-inflammatory chemicals and cytokines may further deteriorate inflammation. Anti-inflammatory drugs play an imperative role in inhibiting the evolution of inflammatory diseases. As per the Unani doctrine, a holistic treatment approach is used to treat illnesses. Therefore, drugs having different actions are used to achieve the synergic effect. Three drugs (Cinnamomum zeylanicum, Alpinia galanga, and Withania somnifera), which are frequently used in Unani medicine for joint disorders were selected to evaluate the anti-inflammatory activity of the extract derived from them. Methods: We used RAW 264.7 macrophage cells to see the expression of inflammatory markers IL-1β, IL-6, and TNF-α. Cytotoxic activity was assessed with MTT assay and Nitric Oxide (NO) was evaluated using Griess reagent. Further, anti-inflammatory activity was evaluated in Wistar Albino rats using carrageenan-induced paw oedema and immunohistochemistry assays for Cyclooxygenase-2 (COX-2). All the data were analyzed using ANOVA and Dunnett t test for multiple comparisons. Results: This extract did not show any cytotoxic effect and the gene expression was significantly reduced for IL-1β, IL-6, and TNF-α in a dose-dependent manner. Further, NO production was also significantly reduced in the test groups. Immunohistochemistry revealed that the test groups had less inflammation as compared to the control group. Conclusion: It may be inferred that the ethanolic extract of the three herbs has strong anti-inflammatory activity in the tested inflammatory models and the extract is safe as it did not show any cytotoxic effects in both in vitro and in vivo conditions. |
