Vetiver is a great oil to promote relaxation and a good night’s rest. But, did you know it has also been shown to help relax blood vessels. A preclinical study found that vetiver essential oil promotes relaxation of blood vessels partly by acting as a calcium channel blocker. Relaxation of blood vessels (reduced constriction) allows blood to flow more freely though the cardiovascular system and helps to lower blood pressure. This preliminary research suggests that vetiver may help maintain healthy blood pressure levels, which is very important for cardiovascular health.
