Rosemary may help boost your brain.

Chefs and home cooks alike love the potent aroma of rosemary for savory dishes such as roasted chicken and red skin potatoes.

Rosemary steams are used therapeutically for decongestion and bronchitis and infusions are used topically as hair rinses.

But now a new study researches the affects of the pungent aroma, itself and it’s ability to improve cognition.

In the study, a cohort of 20 subjects were exposed to varying levels of the aroma, then given a battery of cognitive tests and mood assessments. Not surprisingly, the cognitive performance of the subjects increased, with a corresponding mood increase of lesser magnitude. However, the real surprise came when the blood tests were processed.
