The aim of this research was to create a novel formulation which poses distinctive challenges. Researchers in this study are particularly interested in exploring the perspective of natural bioactive compounds. Various plant extracts have demonstrated therapeutic effects. Cedrus deodara (Roxb.) G. Don, is indigenous to North India, Pakistan, Afghanistan, Tibet, and Nepal. It is rich in various bioactive elements like deodarin, cedodarin, taxifolin, myrcene, iso-pimpillin, α-pinene, β-pinene, cedrin, deodarone, sesquiterpenes, cedrinoside, dihydromyricetin, matairesinol, and atlantone. Traditionally, people have used it to address a wide range of health concerns, including inflammation, ulcers, pain management, blood sugar control, infections, sleep issues, skin conditions, blood disorders, cell death issues, and fever. Recent investigations, both in laboratory settings and within living organisms, have underscored its anti-inflammatory and pain-relieving characteristics. The intended study seeks to formulate and evaluate an herbal microemulgel incorporating an extract from C. deodara to investigate it’s in vitro anti-inflammatory potential. The extraction process involved the use of a hydroalcoholic solvent on C. deodara heartwood, followed by an analysis of the extract's phytochemical composition. Subsequently, four formulations of the herbal microemulgel were prepared for further examination and evaluated for various parameters including pH, spreadability, viscosity, consistency, appearance, color, and washability. The study evaluated the in vitro anti-inflammatory effects of both the C. deodara extract and the formulated microemulgel using HRBC membrane stabilization assay and protein denaturation assay. The volatile oil extracted from the wood of C. deodara was examined for its topical anti-inflammatory activity. It produced significant inhibition of carrageenan-induced rat paw edema and of both exudative–proliferative and chronic phases of inflammation in adjuvant arthritic rats. The findings suggest that the newly developed herbal microemulgel containing C. deodara extract holds potential for future applications in combating inflammation.
