Why a whiff of rosemary DOES help you remember

Shakespeare was right in saying rosemary can improve your memory.
Researchers have found for the first time that essential oil from the herb when sniffed in advance enables people to remember to do things. It could help patients take their medication on time, it is claimed, or even help the forgetful to post a birthday card.
In a series of tests rosemary essential oil from the herb increased the chances of remembering to do things in the future, by 60-75 per cent compared with people who had not been exposed to the oil. Other studies have shown the oil increases alertness and enhances long-term memory.
Rosemary has been long been linked to memory, with the most famous literary reference found in Hamlet when Ophelia declares: ‘There’s rosemary, that’s for remembrance: pray, love, remember.’
 It is used in modern-day herbal medicine as a mild painkiller and for migraines and digestive problems.
A team of psychologists at Northumbria University, Newcastle, tested the effects of essential oils from rosemary.
Dr Mark Moss, who will present the findings today at the British Psychology Society conference in Harrogate, said the benefit of aromas was becoming clear through scientific investigation.
