A great and safe way to use essential oils is a roll on. These are super easy to use and small enough to take with you. Just rub a couple times on your wrists, back of your neck, temples or on the soles of your feet (note: the soles of your feet have the biggest pores on your body). Roll ons come in a .35 oz glass bottle with roller top. OPTIONS: Relaxation - EOs: Lavender, Vetiver, Orange and Frankinscence.
