According to a new study, the aroma of rosemary oil may improve prospective memory in adults. We wanted to build on our previous research that indicated rosemary aroma improved long-term memory and mental arithmetic. The findings suggest that rosemary essential oil may enhance the ability to remember events and to remember to complete tasks sniffing rosemary can increase memory by 75 snopes particular times in the future. Rosemary essential oil was diffused in to a testing room by placing four drops on an aroma stream fan diffuser and switching this on five minutes before the participants entered the room. 66 people took part in the study and were randomly allocated to either the rosemary-scented room or another room with no scent.
In each room participants completed a test designed to assess their prospective memory functions. This included tasks such as hiding objects and asking participants to find them at the end of the test and instructing them to pass a specified object to the researcher at a particular time. All the tasks had to be done with no prompting. If the task was not performed then different degrees of prompting were used. The more prompting that was used the lower the score. Participants also completed questionnaires assessing their mood. The compound is also found in the essential oil of rosemary and has previously been shown to act on the biochemical systems that underpin memory. The results showed that participants in the rosemary-scented room performed better on the prospective memory tasks than the participants in the room with no scent.
This was the case for remembering events and remembering to complete tasks at particular times. There was no link between the participants’ mood and memory. The results from the blood analysis found that significantly greater amounts of 1,8-cineole were present in the plasma of those in the rosemary scented room, suggesting that the influence of aroma was mediated pharmacologically. These findings may have implications for treating individuals with memory impairments.
It supports our previous research indicating that the aroma of rosemary essential oil can enhance cognitive functioning in healthy adults, here extending to the ability to remember events and to complete tasks in the future. Remembering when and where to go and for what reasons underpins everything we do, and we all suffer minor failings that can be frustrating and sometimes dangerous. Further research is needed to investigate if this treatment is useful for older adults who have experienced memory decline. Can Rosemary Aroma enhance Prospective Memory? This study is the first to unveil a gut-brain connection linking high dietary salt intake to neurovascular and cognitive impairment. Research from the Rockefeller University suggests that variability between strains of the same bacterial species could influence patient immune response.
