A study shows that smelling rosemary can improve cognition.
20 participants were exposed to varying amounts of rosemary while doing subtraction and visual processing tasks. Rosemary oil didn't increase attentiveness, but those exposed to more rosemary did their tasks faster and better. The key component - 1,8-cineole - is also found in eucalyptus and sage essential oils.
