The impact of inhaling essential oils on cognitive function and the brain had not been well-understood. In this study, researchers used electroencephalography to examine the effects of inhaling lemon, sandalwood, and kusunoki essential oils on memory function and brain activity. While all three oils showed some effect on cognitive function, kusunoki oil appeared to be the most powerful. This study offers insight into the potential benefits of essential oils on cognitive health, specifically memory.
