Relieves Stress and Treats Inflammation

Free radicals (also called Reactive Oxygen Species) that cause oxidative stress are directly associated with inflammation, aging, and carcinogenesis. The body possesses various anti-oxidative systems and saliva is one such system. In one study on rosemary benefits, Japanese researchers found that smelling of lavender and rosemary essential oils in aromatherapy increased the production of saliva and reduced the stress hormone cortisol levels significantly. They concluded that these oils could protect the body from oxidative stress and relieve stress. Other studies too have confirmed that rosemary leaves exhibit potent anti-inflammation and anti-tumor effects. Rosmarinic acid increases the production of prostaglandin E2 (substances that help in contraction and relaxation of smooth muscle, the dilation and constriction of blood vessels, control of blood pressure, and modulation of inflammation) and reduces the production of leukotriene B4 involved in inflammation.
