Rosemary for Memory

Scientists have found that aromas can profoundly affect people's cognitive abilities. In a 2003 study, psychologists asked 144 volunteers to perform a series of long-term memory, working memory, and attention and reaction tests. Some subjects worked in a scent-free cubicle, some in a cubicle infused with essential oil from rosemary, and the rest worked in cubicles scented with lavender oil.

Those in the rosemary-infused cubicles demonstrated significantly better long-term and working memory than those in the unscented cubicles. Also, those exposed to the smell of rosemary reported feeling more alert than the control (scent-free) group.

Participants working in the lavender cubicles reported feeling less alert and those in the lavender-scented cubicles performed worse than the others in tests of working memory.

If you need your brain to perform at its best, you can try placing a rosemary plant on your windowsill. Research also shows that eating chocolate may improve memory and cognition, because it is rich in antioxidants called flavanols.
