Clove essential oil is rich in substances with antioxidative and antibacterial effects. It can contribute to a healthy function of the respiratory tract in horses.


Clove oil is an essential oil of plant origin which is extracted from the dried buds, leaves or stems of the clove tree by steam distillation.


Clove is rich in volatile oils principally eugenol (70-90%), eugenyl acetate (17%) and B-caryophyllene as well as flavonoids, galloytannins, phenolic acids and triterpenes. Clove oil has antihistaminic and antispasmodic properties, most likely caused by eugenyl acetate. Furthermore, clove oil has mild antiseptic properties which have been attributed to eugenol.

Possible uses

The eugenol contained in clove oil in particular has been described as having antibacterial properties which, in combination with the antioxidant effects of clove oil, can have a positive effect on respiratory health.
