The UK Telegraph has an article citing scientific studies at Northumbria University in the UK that rosemary can enhance memory significantly. Even being in the same room with the live plants was found to improve the memory of a group of retirees in the study.
“English folklore advises slipping rosemary into the pocket of an errant lover to help them remember their vows, while Ophelia confirmed the herb is ‘for remembrance’ in Shakespeare’s Hamlet. Now scientists have shown that the plant really is linked to better memory.”
