Top 10 Essential Oils for Brain Fog

Essential oils support brain function on many levels from oils that stimulate the brain, calm the nervous system to relieve the fight or flight response, to oils that help reduce inflammation throughout the the body which can also lead to brain fog.

The Powerful Sense of Smell

sense of smellEssential Oils directly access the brain through the olfactory bulb which is strongly linked to emotional state and memory function. The olfactory system is connected to the hippocampus, brain stem, auditory cortex and many other areas of the amygdala. This means that through our sense of smell we are able to positively influence thought processing. Going beyond the scent of Lavender reminding you of your Grandma it will also help to calm the brain stem and assist with auditory learning.


Crossing the Barrier

Another way that essential oils assist with brain health is through the blood-brain barrier. The brain has a unique built-in protective system that prevents toxins and harmful substances from affecting the brain. The blood vessels are lined with endothelial cells that create a barrier between the blood system of the brain and the rest of the body. Many drugs are not able to cross this barrier to help heal the brain. Essential Oils have this ability to cross the blood-brain barrier and act quickly to reduce inflammation and assist cellular regeneration.
