Sprays are best used for its energetic impact. Add 10-15 drops of essential oil per ounce of alcohol. This is very similar to making a liniment. Alcohol should be used rather than water. Alcohol has a cleansing effect just by itself and seems to more evenly disperse the oil. Sprays are a great place to use the oils that are caustic or sensitizing since you are not spraying directly on the skin.
