The aroma of rosemary essential oil may improve memory in healthy adults, according to researchers at the University of Northumbria.
The smell of rosemary could boost your memory
The smell can increase the ability to recall events and remember to complete tasks at certain times, they said.
A group of 66 people were given memory tests, either in a rosemary-scented room or another room with no odor.
Participants were given various tests to assess their memory functions, including searching for hidden objects and passing specific objects to researchers at a given time.
The results, presented at the British Psychological Society annual conference in Harrogate, showed that participants in the rosemary-scented room performed better on prospective memory tasks than those in the odor-free room.
"We wanted to build on our previous research indicating that the aroma of rosemary improves long-term memory and mental arithmetic," said author Dr. Mark Moss.
“In this study we focus on prospective memory, which involves the ability to recall events that will occur in the future and remember to complete tasks at certain times. This is essential for daily operation. For example, when someone needs to remember that they have to send a birthday card or take medication at a certain time ".
Co-author Jemma McCready added: “These findings may have implications for the treatment of people with memory problems.
“It supports our previous research indicating that the aroma of rosemary essential oil can improve cognitive functioning in healthy adults, extending here to the ability to remember events and to complete tasks in the future.
“Remembering when and where to go and for what reasons sustains everything we do, and everyone suffers from minor deficiencies that can be frustrating and sometimes dangerous. Additional research is needed to investigate whether this treatment is helpful for older adults who have suffered from memory loss. "
