How Rosemary Oil Benefits Health

May Reduce Stress

Several studies have suggested rosemary oil may reduce stress, which can cause the heart rate to be temporarily elevated. A study of nursing students taking particularly stressful academic exams measured their pulse rates before and during these exams. Some of the students were asked to inhale rosemary oil through an inhaler for the study, and the control group was not given any oil. The results showed the students who had inhaled rosemary oil experienced a nine percent decrease in their pulse, and the students in the control group had no decrease. In addition to an increased pulse rate, stress can also cause elevated cortisol levels. A study of twenty-two adults showed those who inhaled rosemary oil for five minutes experienced a twenty-three percent reduction in cortisol. The control group inhaled a neutral oil, and no reduction in cortisol levels was demonstrated. Additional studies have shown rosemary oil may help improve mood and make patients feel more energetic.
