Fast forward to 2012, the researchers are finally able to scientifically explain the cognitive-boosting abilities of the herb (2). This is what they discovered…
The new study followed twenty people as they performed subtraction exercises as well as visual information processing tasks and other tests. Their mood was also assessed before and after being exposed to the scent of rosemary in their work stations and blood samples were drawn.
Altogether, 66 people took part in the study and were randomly assigned to either the rosemary-scented room or another room with no scent.
The results showed that participants in the rosemary-scented room performed 60-75% better on remembering events to completing tasks at particular times as well as recalling things faster than the participants in the room with no scent. So it definitely demonstrates an increase memory for many people.
