Essential oils of plant origin are complex mixtures of volatile and semi volatile organic compounds that can modulate the immune response. Plant derived essential oils may be useful complementary or alternative medicine for the treatment of animal diseases. The objective of this study was to evaluate the effect of essential oils on the concentration of Galectin 3 protein (Gal-3) in cow blood. Blood was collected form three Holstein fresian cows at the NC A&T Dairy. One milliliter of blood was treated with 100 ul of lemon, cinnamon or clove oil. The packed cell volume (PCV), total viable and differential white blood cell counts were measured before and after essential oil treatment. Differential effects of oils were observed. The Gal-3 ELISA test results showed that treating blood with essential oil increased Gal-3 concentration by 11%, 12%, and 23% for cinnamon, clove, and lemon respectively. Continued studies are suggested to focus on different concentrations of essential oils, a more diverse group of animals and information including the effects on gene expression.
