There are several different types of basil oil. Absolute Aromas has selected a True Sweet Basil Oil (Ocimum Basilicum) known as Linalol type. This is the safest & most pleasant of the Basil oils used in aromatherapy. A stimulating & clearing oil useful when concentration is needed or when feeling tired. Try adding 1 drop of Basil & 3 drops of Lemon to the water in an oil burner to help create the right atmosphere for hours of exam revision or paperwork! A blend of 1 drop each of Basil & Lavender in 10ml of Sweet Almond oil makes a good abdomen massage oil. Always massage the abdomen in a clockwise direction. Do not use during pregnancy & only in moderation especially by those with sensitive skin.
