When your mind is tired and in need of stimulating and an uplift, then spearmint oil is the one for you, and although it has very many properties in common to that of peppermint oil, it contains only small amounts of menthol and is far less harsh on the skin and ideal for use in children.  Spearmint essential oil benefits  the digestive system and relieves flatulence, constipation, vomiting and nausea, as well as the respiratory tract to relieve cough, bronchitis, asthma, catarrh and sinus. On the skin it calms itching and has a stimulant action on the mind. 

Although most essential oils blend well together, Spearmint oil blends particularly well with Basil, Eucalyptus, Lavender, Rosemary and Jasmine.
