Aromatherapy is actually a form of herbal medicine. However, instead of using the entire herb, it employs the fragrant "essential oil" that is released when a fresh herb is compressed or subjected to chemical extraction. Essential oils are also often used as fragrances in cosmetics and bath products.
When employed medicinally, essential oils are often evaporated into the air through the use of a humidifier. The famous Vicks VapoRub is a gel form of the essential oils of peppermint, eucalyptus, and camphor. Certain essential oils may also be applied directly to the skin or clothes so they will release their odor near the patient. Some essential oils are designed to be taken by mouth, but this is an uncommon usage.
What Is Aromatherapy Used For?
Inhaled aromatherapy has become a popular, gentle treatment to reduce mild anxiety. It has also been tried for a variety of other conditions, including respiratory problems, postsurgical nausea, menstrual pain, and tension headaches.
Topical treatment with essential oils has shown possible value for fungal infections and hair loss. Essential oils specifically desigend for oral use have shown some promise for various digestive and respiratory problems.
What Is the Scientific Evidence for Aromatherapy?
Thus, everything written below about true aromatherapy—that is, inhalation of an aroma—must be taken with a grain of salt.
These problems do not arise to the same extent in studies of essential oils taken by mouth or applied directly to the skin.
Inhalation of Essential Oils
Oral Use of Essential Oils
Eucalyptus is a standard ingredient in cough drops and cough syrups, as well as in oils added to humidifiers. A standardized combination of eucalyptus oil plus two other essential oils has been studied for effectiveness in a variety of respiratory conditions. This combination therapy contains cineole from eucalyptus, d-limonene from citrus fruit, and alpha-pinene from pine. Because these oils are all in a chemical family called monoterpenes, the treatment is called essential oil monoterpenes .
How Might Aromatherapy Work?
It is not clear how inhaled aromatherapy works (assuming that it does). Possibly, enough is inhaled through the lungs to produce meaningful concentrations of herbal chemicals in the body. It is also possible that aromatherapy might work through the olfactory centers of the brain. In other words, a pleasant fragrance may be soothing, refreshing, calming, and stimulating—hardly a revolutionary concept!
How to Choose an Aromatherapy Practitioner
For all intents and purposes, licensure in aromatherapy does not exist. For this reason, the best way to find a qualified practitioner is to seek a referral from a healthcare professional.
