Many people love lemon essential oil because of its uplifting aroma and ability to promote feelings of happiness but a recent preclinical study suggests it may help you retain those happy memories as well. Inhalation of lemon essential oil reversed cognitive decline in an experimental model of Alzheimer's disease by improving synaptic density in the hippocampus (an area of the brain important for short- and long-term memory) and making more acetylcholine available to the brain (a neurotransmitter important form memory and learning). Overall, the research suggests that lemon oil may help improve memory and cognition.
