Washington: Aroma of essential oil from the herb rosemary could help improve memory in healthy adults, researchers have claimed. The researchers from Northumbria also said the smell may also enhance the ability to remember events and to remember to complete tasks at particular times, the Independent reported.

For the study, a group of 66 people were given memory tests in either a rosemary-scented room or another room with no scent. They were then assigned various tests to assess their memory functions, including finding hidden objects and passing specified objects to researchers at a particular time.

The results showed that study participants in the scented room performed better on the prospective memory tasks than those in the room with no smell. Dr Mark Moss, author of the study, said that in the study his team focused on prospective memory, which involves the ability to remember events that will occur in the future and to remember to complete tasks at particular times.

Co-author Jemma McCready said that these findings may have implications for treating individuals with memory impairments. She added that the study supports their earlier research that indicated that the aroma of rosemary essential oil could enhance cognitive functioning in healthy adults, and extended to the ability to remember events and to complete tasks in the future.
