The essential oils in this synergy have been known to improve a persons memory and concentration.  I know I would not have been without it during the time I was taking my courses, and I continue to use it when I want to retain or recall new information.
The combination of Rosemary-Basil-Lavender also has a pleasant aroma.  This synergy is ment to be inhaled and not applied to the skin.  You can drip 2-3 drops onto a tissue and inhale anytime you need it, or you can place 5-6 drops in water in the top of a diffuser. (or what ever kind of diffuser you have)
Keep out of reach of children.
Avoid during pregnancy or nursing.
