Does Rosemary aroma really improve memory? Here’s what research says

A 2003 Northumbria University study revealed that rosemary essential oil enhances memory and cognitive functions, particularly mental arithmetic speed and accuracy. The study found a correlation between blood levels of 1,8-cineole, a rosemary compound, and improved cognitive performance. Rosemary’s potential applications range from enhancing focus in students to cognitive care for the elderly.
