SMELLING rosemary could help boost the memory as it activates chemicals in the brain. Researchers claim that the smell of rosemary aids the ability to recall past events and also helps us remember what to do in the future.
It is thought a compound that gives the herb its distinctive smell, called 1,8-cineole, helps a brain chemical which is the key to memory, with the plant having an almost ‘drug-like effect’, according to the researchers.
Volunteers carried out memory tests while sitting in a room infused with rosemary oil, with another group having the same tests in a lavender fragranced room and another in one with clean air.
Rosemary was found to boost long-term memory and the ability to do simple sums. It also improved ‘prospective memory’ used to carry out plans, such as remembering to post a letter.
