Smell of rosemary improves memory
It increases the ability to remember past events and do things. Can you imagine how useful it could be to remember that we have to take a medication or even to help us not forget to congratulate someone?
Rosemary has been used as a mild analgesic, for migraines and for digestive problems. And his ability to improve memory is found even in the literature. In Hamlet, one of Shakespeare’s works, reference was already made to the properties of this aromatic herb.
A team of psychologists at the University of Northumbria in Newcastle has tested the effects of rosemary essential oils by improving memory.
It improves the ability to remember things.
The results of this new study suggest that rosemary essential oil can increase the ability to recall past events and complete future tasks.
For the study was spread rosemary oil in a room, placing four drops in a diffuser of aromas.
The 66 study participants were randomly assigned to perform a series of tasks in a room smelling of rosemary or in another room without odor. They had to complete a series of memory tests, such as hiding objects and finding them later.
Participants also completed questionnaires to assess their mood and performed blood tests to see if the level of performance and changes in mood when exposed to rosemary aroma were related to the concentration of 1,8- Cineol in blood.
1,8-cineol is a compound present in rosemary essential oil, and that previous studies have shown that it interferes with memory-related biochemical systems.
People who had been assigned to the rosemary-scented room performed better than those who tested in the non-rosemary room. They were able to remember facts and complete tasks at certain times. They also had higher levels of 1,8-cineol in the blood.
