Lorraine Oliver and Mark Moss, researchers from Northumbria University in Newcastle, have found that cineole, a component of rosemary, has a positive effect on mood. This research was carried out by inhaling dried rosemary leaves and rosemary essential oil, and it was confirmed that it improves memory, relieves mental fatigue, and stabilizes the cardiovascular system and blood pressure. Rosemary oil is used by infusing it in bath water, and it is also used as a fragrance by infusing it on lamps and heating batteries. Do not put more than 5 drops in the bath water. For the first time, you only need to put 3 drops. It enters the body very easily through the smell. Incense with this oil can cure respiratory ailments, from colds to asthma. Add 5 drops of oil to water for incense. For aromatic use, 5 drops are also applied to light bulbs and batteries.
