An essential oil is a concentrated liquid
containing volatile aroma compounds from plants. Essential oils are
also known as volatile oils, or ethereal oils. An oil is 'essential'
in the sense that it carries a distinctive scent, or essence, of the
plant. Essential oils do not form a distinctive category for any
medical, pharmacological, or culinary purpose. They are not
essential for health.
Sage is best for blood-pressure reduction. In a 2013
study, women who smelled clary sage experienced reduced blood
pressure and breathing rates. They were also able to relax during a
stressful medical exam. Sage also increases memory and attention.
Peppermint is best for stress relief. Research shows that
breathing in eau de peppermint can decrease the body's levels of
cortisol, a stress hormone. It also reduces fatigue.
Orange is best for decreasing anxiety. A study found that
people who sniffed it before a stressful test were able to stay
calm under pressure without anxiety spikes.
Rosemary is best for enhancing brainpower. Breathing it in
can improve speed and accuracy during demanding mental tasks, per
a 2012 study. Other research found its scent left people feeling
refreshed and mentally stimulated. It also has been known to
reduce fatigue.
Cinnamon is best for improving focus. It may stoke the
area of the brain that governs alertness. Research found that
drivers were more focused after breathing in cinnamon-oil scents.
Lavender increases relaxation and relieves some symptoms
of PMS. A 2013 study found that it also eases pre-period symptoms
such as mental confusion and depression. It also reduces some
migraine pain.
Olive Oil may help you lose weight, according to a recent
study in the American Journal of Nutrition. It says the scent of

A diffuser is the most effective way to unleash essential oils
into the air, but you can add one or two drops of oil into a bowl
of steaming hot water. Another option is to place one drop of oil
on a cotton ball, put it under your nose, and inhale normally for
one to two minutes.
Essential oils should never be used for more than one hour at a
time. Look for 100 percent pure and organic oils free of fillers,
pesticides, and synthetic chemicals.
