The main objective of this study was to develop and evaluate self-nanoemulsifying drug delivery system (SNEDDS) of curcumin (Cur) to enhance their solubility as well as improve skin permeation; and evaluate wound healing potential of Cur via SNEDDS in comparison with standards pure eucalyptus oil-SNEDDS (Euc-SNEDDS), pure curcumin suspension (Cur-S), and standard fusidic acid followed by their anti-inflammatory action. Curcumin-loaded different SNEDDS formulations were formulated through aqueous...
