Washington DC: Do you think sniffing rosemary is beneficial for us?
Well, a new study have shown that sniffing the aroma of rosemary could be beneficial for elderly people as it can help improve the brain power.
Researcher Lauren Bussey of Northumbria University said that during the study, they focused on the prospective memory that involves the ability to remember to complete tasks at particular times and also to remember events that will occur in the future.
Around 150 people aged over 65 took part in the study and were randomly allocated to either the rosemary or lavender-scented room or to another room with no scent.
Before the participants entered the testing room, rosemary and lavender essential oil were diffused in the room by placing four drops on an aroma stream fan diffuser and switching this on five minutes.
Once in the room, they undertook tests designed to assess their prospective memory functions. These included remembering to pass on a message at a given time during the procedure, and switching tasks when a specific event occurred. These tasks represent the two components of prospective memory: time-based and event-based.
Participants also completed mood assessment before and after undertaking tests in the scented or non-scented rooms.
Analysis of the results showed that the rosemary aroma significantly enhanced prospective memory compared to the room with no aroma. In terms of mood, rosemary significantly increased alertness and lavender significantly increased calmness and contentedness compared to the no aroma control condition
Bussey noted that further investigation is required to understand the potential benefits of these aromas throughout the life span.
The study has been presented at the British Psychological Society's Annual Conference in Nottingham.
