Objective: Novel nanovesicular gel of Berberis aristata extract was developed and evaluated for its anti-inflammatory and antipsoriatic activity. Materials and Methods: Transferosomes were prepared using soya phosphatidylcholine and edge activators (Tween 80, Span 80, and sodium deoxycholate) by a modified lipid film hydration technique using rotary evaporator and evaluated for various parameters. The quantification and standardization of extract have been carried out using its alkaloid content as berberine as biomarker. Topical application of imiquimod (IMQ) (immune modifier) on the shaved back of mice developed psoriasis-like inflammation followed by histopathological study of inflamed skin. Results: The size of transferosomes was in the range of 265–345 nm whereas polydispersity index ranges from 0.10 to 0.63, and for zeta potential, it was from −19.3 to −43.3 mV. Transferosomes were further added to Carbopol 934P for gel formation and subsequently evaluated for their physicochemical properties. Their efficacy against inflammation, IMQ-induced psoriasis, and skin sensitivity was compared with conventional formulation (commercial formulation-Angle Gloss, Phytolab Pvt. Ltd.). Percent inhibition of edema by transferosomal gel (55.76%) was more as compared to conventional gel of extract (33.5%) found out by Carrageenan-induced paw edema method. Primary irritation index was found to be <0.4 inferring its safe use for topical formulation. Conclusion: Histopathological report showed that, in psoriasis-induced animal treated with topical application of extract loaded transferosomal gel showed a marked reduction in thickness of epidermis, length of rete ridges as compared to conventional gel formulation. It can be inferred that B. aristata extract loaded transferosomal gel can function as potential anti-inflammatory and antipsoriatic formulation.
