Combine the essential oils. Then stir into an appropriate amount of magnesium lotion. (3 drops of the essential oil blend to 1 teaspoon of lotion equals a 3% dilution. That's 9 drops for 1 Tablespoon.)

Store it in a covered glass jar, preferably a dark one, but use what you have. A baby food jar is a good size, but you'll need to store it in a dark place.

Over time, this may separate a little. Just stir it back in before use.
