Avoid undiluted skin contact. Clove is high in a component called eugenol, a phenol. Phenols are considered to be the most irritating components to the skin and mucous membranes and can cause dermatitis and sensitization. If phenols are present in high concentrations in an essential oil, that oil should be used in very low dilutions on the skin (1% in a carrier) and for short periods of time. They are generally not safe for the skin in a bath.
Oils high in phenols should not be used for babies and children.
Robert Tisserand, in his book Essential Oil Safety, states that oils high in eugenol should be used with caution on those with impaired liver function.
People with clotting disorders should not use eugenol high oils (like clove), as eugenol is an anticoagulant.
If pregnant, nursing or under a doctor’s care, consult your physician or clinical certified aromatherapist. For external use only. Keep away from mucous membranes & eyes. Test a small amount on skin for allergic reaction. Keep out of reach of children. Avoid using on infants and small children under the age of five years old.
Always dilute essential oils with a carrier oil.
