Anti-inflammatory activity of the topical formulation of Drymoglossum piloselloides (L) Presl. extract on mice

Background: Chronic inflammation of the joints that occur in the condition of gout or osteoarthritis and rheumatoid arthritis often causes repeated inflammation which requires patients to take a long-term pain medication, leading to serious side effects. Alternative treatment especially from herbal ingredients in a topical form is needed. Objective: This study aims to evaluate the anti-inflammatory activity of the leaves extract of Drymoglossum piloselloides (L) Presl. in mice to prove their potential as an anti-inflammatory agent. Methods: Mice were divided into four groups (n=7), namely positive control (sodium diclofenac emulgel), negative control (placebo), P1 (emulgel extract 2.5%), and P2 (emulgel extract 5%). The anti-inflammatory activity test was carried out on mice with carrageenan-induced paw edema by measuring the relative changes in the volume of inflammation at 0 and 3 hours after treatment. Data were analyzed using the Kruskal-Wallis and Mann-Whitney tests with a confidence level of 95%. Results: The emulgel contained flavonoids, triterpenoids, steroids, tannins, and quinones. The anti-inflammatory test showed a significant inhibition of inflammation (p <0.05) at concentrations of 2.5% and 5%. This anti-inflammatory activity could be influenced by the phytochemical compounds contained in the emulgel. Conclusion:Drymoglossum piloselloides (L) Presl. emulgel at concentrations of 2.5% and 5% had an anti-inflammatory activity on mice with carrageenan-induced paw edema.
