Here's how essential oils affect you
Our ability to smell depends on small molecules in the air. When we inhale these molecules, they are recognized by receptors in the nose. The information is transported via the nerves to the brain, including the parts responsible for emotions, behavior and memory. The fragrance molecules dissolve in the blood and thus make the active properties work.
For example. if you have a headache or migraine, you can use one or more of these essential oils in a diffuser: chamomile, lavender, marjoram, neroli, rosemary.
