A team of scientists has shown that sniffing rosemary can increase the memory by 75%. This multi-purpose medicinal herb offers numerous health benefits due to which it has been commonly used throughout the history.
One interesting fact is that the ancient Greeks wore rosemary springs in the hair while studying for their exams.
This amazing herb has been used to boost long-term memory and alertness for millennia. Even the famous Shakespeare mentions the incredible benefits of the rosemary in “Hamlet”.
A study conducted at the Northumbria University, Newcastle in 2003 found that smelling rosemary is related to “an enhancement of performance for overall quality of memory and secondary memory factors”.
After ten years, these scientists scientifically explained the cognitive-boosting abilities of the herb. Namely, the experts followed twenty people as they performed subtraction exercises and visual information processing tasks and other tests. They assessed the mood of the participants before and after the exposure to the rosemary scent and took blood samples.
The study involves 66 people altogether, and they were randomly assigned to either the rosemary-scented room or another room with no scent.
