Boost is a blend to defend, protect and boost your body's natural immune system. Put a few drops on a tissue and inhale to ward off infections. To use as a massage oil, blend 5 drops with 10ml of carrier oil such as Jojoba Israel or "Undressed" and massage into the feet to boost your body's immune system. Or, try diffusing in your home or in the office to prevent the spread of seasonal colds.
