Can Sniffing Rosemary Raise Your IQ?

Can Sniffing Rosemary Raise Your IQ?

A new study shows that smelling the herb can actually increase cognitive function.

A new study has discovered that the main chemical component in rosemary can increase brain function.

Scientists from the University of Northumbria found that test subjects’ cognitive function improved when they smelled the herb. Sniffing rosemary increased both speed and accuracy in test subjects, who were required to perform certain mental tasks, and seemed to alter mood as well. The highest test scores in the study correlated to the highest concentration of the main chemical component of rosemary, called 1,8-cineole, in the blood.

No one knows just why the chemical does what it does, and there is still much to be learned. That said, the study’s’ findings open the door to a whole new array of sensory research and pharmacology. Not to mention the possible implementations of scent outside the world of medicine. It seems, for IQ’s sake, it’s time to take another look at aromatherapy.

The study was recently published in Therapeutic Advances in Pharmacology.
