The application method chosen depends on the desired effect and the essential oil selected. For example, some essential oils are irritating to the skin because of their chemistry. These would need more dilution or might better be used by inhalation.
Once you have purchased an essential oil, the application method depends on the condition to be treated and the desired effect. Some tips:
Note: If you are unsure about which application method to use with essential oils, consult an qualified aromatherapist.
Essential oils are placed in this device, sometimes with water (be sure to read the directions), and sometimes with heat so they evaporate. This is a good way to add the scent of an essential oil to a room, for example to add lavendar if you want to enhance relaxation in a yoga session or class. Essential oils should never be directly burned as the chemical structure is dramatically changed with incineration (Buckle, 2003).
Several drops of essential oil are placed on a cotton ball or tissue and allowed to evaporate into the air. If you want an intense dose, sniff the cotton ball. If a milder, more constant exposure is desired, simply keep the cotton ball in your immediate vicinity (for example, leave it sitting on your desk next to your computer).
Drops of essential oil are added to a bowl of steaming water, which quickly vaporizes the oil. Place a towel over your head and over the bowl of water with essential oil drop(s) and breathe deeply. This method is very direct and potent—the use of more than 1-2 drops may be overwhelming. It is important keep the eyes closed when using this method. The use of eucalyptus essential oil in this way can feel helpful with upper respiratory and sinus infections Note: This is not recommended for children younger than 7 years old. Children older than 7 can use swimming goggles to protect their eyes.
Drops of essential oils are placed in a water-based solution, shaken, and sprayed into the air in order to deodorize a room or set a mood. An example might be spraying an aqueous solution of pine or citrus oils to enhance holiday feelings or a solution of peppermint oil to stimulate alertness. You might also want to use a solution of water and your favorite essential oil as a yoga mat cleaner. It is important to shake the bottle before spraying in order to spray the solution and not just water.
