The study was aimed to design a nano emulsion formulations of Sage oil and to determine its effectiveness in healing the wound using rats as a model. Sage oil nanoemulsion (o/w) was formulated by a spontaneous emulsification method and tested for physicochemical parameters. The wound creation methods namely; circular excision and linear incision were utilized in the present study. Many specifications like tensile strength, DNA, total protein, Hexosamine and Uronic acid, were estimated from the tissues collected from incised wounds. The antioxidant and antimicrobial activity of the oil was estimated from the wound tissue homogenate. Finally epithelialization period and concentration of TNF-α were also measured. A Significant rise in collagen content by 77.52% and tensile strength by 56.20% were noticed in comparison to control. Reduction in period of epithelialization was noticed by 42.85% in comparison to control. The treatment groups confirmed significant antimicrobial activity in comparison to control. It was evident from the results that Sage oil nano emulsion could be the accelerator in wound healing process and it may be devoid of other drawbacks which would be possible with synthetic drug.

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from the leaves of L. (sage oil) when used as a sensory additive in feed and in water for drinking for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that sage oil is considered safe up to the maximum proposed use levels in complete feed of 20 mg/kg for ornamental fish.

(clary sage oil) when used as a sensory additive in feed and in water for drinking for all animal species. The EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive under assessment is considered safe up to the maximum use level in complete feed of 15 mg/kg for veal calves (milk replacers), cattle for fattening, sheep/goats, 10 mg/kg for horses, 20 mg/kg for dogs, salmonids and ornamental fish.

The cultivation of , Spanish sage, makes an important contribution to the economy of many rural areas in Southeastern Spain. This aromatic plant species is characterized by high intraspecific variability, which makes the selection process for the establishment of homogeneous crops difficult. Additionally, imminent climate change threatens to reduce its production, especially when cultivated in drylands.
