An excellent, aromatic nerve tonic. Good for lack of concentration, this oil has an uplifting and clarifying effect on the mind, thus aiding the attention span. With these qualities and its stimulant effect, it can be helpful during long journeys when the driver is sleepy.
Basil also helps to alleviate headaches and bronchial problems.
It is contraindicated in pregnancy and should be used in caution in people with sensitive skins.
Blends well with Bergamot and Geranium.
