I am not an aromatherapist, I have little knowledge of all the uses and benefits , but there are many ways you can utilize Essential Oils in your everyday life. If in doubt you must always contact a professional
Inhaling essential oils is much safer than oral use. The oils are biologically active when the airborne molecules are inhaled, stimulating olfactory nerves, which in turn stimulate centers of the brain. The molecules may trigger an immune response after entering the bronchial area and lungs, helping your body fight infection, for instance.
