Rosemary is herb which has been used for centuries in traditional medicine because of its healing properties. One of its known properties is that it can improve the memory. The students in ancient Greece use it when studying. They used to put rosemary sprigs in their hair.
Many studies showed that rosemary has carnosic and natural acids in its content, acids which protect the brain, body cells and DNA from free radical damage. Rosemary has compounds which can prevent the breakdown of acetylcholine, the chemical which generates the brain cells responsible for memory.
Numerous tests have proved that rosemary essential oils have the ability to increase the chances by 60-75% of remembering that you have to do some something in the future, in a comparison with people who did not use the oil.
According to the study published in the Therapeutic Advances in Psychopharmacology, the chemical compound 1,8-cineole is “guilty” for the improved function of the memory. Subjects in the study need to inhale rosemary extract before they perform certain tasks, while testing their stress levels, mood, speed, and accuracy. The results were expected: people who absorb more 1,8-cineole into their bloodstream, have more positive results than the others!
It is also used as a mild painkiller, and for digestive problems and migraines.
