There are several ways you can benefit for aromatherapy.  When inhaled into the lungs, it offers both psychological and physical benefits.  When inhaled into the lungs, the natural constituents can supply therapeutic benefits.  The aroma of the natural essential oil can also stimulate the brain to trigger a reaction.

When applied to the skin, essential oils can aid in health, beauty and hygiene conditions.  And if that is not enough, essential oils can be used in laundry, candles and many other things. 

• Essential oils should never be taken internally.
• To prevent allergic reactions, first test any essential oil on a small patch of clean skin. Mix a drop of the essential oil with a few drops of an unscented carrier oil, such as grapeseed oil.  If no irritation occurs, you can use the oil. If you develop a rash, try another essential oil.
• If you become sensitive to an oil after using it for a while, discontinue use.
• If you have asthma or other respiratory concerns, consult your doctor before doing aromatherapy, because certain aromatherapy oils can trigger bronchial spasms.
• Unless you're very familiar with aromatherapy, it's best to avoid using it during pregnancy. The essential oils of basil, thyme, clary sage, calamus, mugwort, pennyroyal, sage, rosemary, juniper, and wintergreen can all harm the fetus or induce miscarriage if taken internally, or even possibly if applied externally.
