Aromatic essential oils from plants, when inhaled, enter the bloodstream through the nose and lungs, and can easily pass the blood-brain barrier. But doctor’s don’t know how essential oils influence human behavior. In this study, 20 healthy people carried out a series of math subtraction tests and visual tasks while sitting in a cubicle diffused with rosemary essential oil. As levels of rosemary oil molecules in the blood increased, test speed and accuracy both improved. Researchers also noticed a secondary link to changes in mood, suggesting that essential oils may affect mood and performance through different pathways.
