Lemon essential oil can be used in conjunction with a steam inhalation treatment for wheezing, colds, cough, and other upper respiratory problems. Note that this should not be used in those with asthma.
To take a steam inhalation treatment with lemon essential oil, fill a large bowl or pan with boiling hot water and a few drops of lemon essential oil. Place the afflicted person's head over the bowl and then place a towel over the head and bowl (in a tent-like fashion), so that no steam escapes.
The person should take a few deep breaths, breathing the vapors in deeply for a couple minutes. If at any time, the treatment causes you to feel uncomfortable, stop right away. As with any medical treatment, contact a licensed medical professional before starting any medical treatment.
Lemon is a disinfectant and can be used as a deodorizer, neutralizer, and air sterilizer. Simply add a few drops of the lemon essential oil to a spray bottle filled with water. The same concoction can also be sprayed onto tables, counter tops and other surfaces. Test an inconspicuous area on the surface before use by adding a small amount and waiting 24 hours for the effect (if any). The oil can be good for many surfaces, but it also could damage some.
Lemon essential oil can be used as a mouthwash. Add a couple drops to a 4 oz glass of water and gargle. The disinfectant properties are great for germs in the mouth and for neutralizing bad breath odors, as well.
For a quick, refreshing energy boost, combine a couple drops each of lemon essential oil and peppermint essential oil in a glass of water and drink up.
Put a few drops of lemon essential oil in a spray bottle filled with water and spray onto the skin as an insect repellent. However, do not use this repellent method in the sun. Lemon oil can do damage to the skin if the treated skin is exposed to the sun. Avoid sun exposure for 12 hours after applying lemon essential oil to the skin. This method is best used at night or on cloudy and cool days.
Add a couple drops of lemon essential oil to a glass of water. Drink the full glass. This is said to relieve heartburn symptoms by neutralizing the acid.
Cough, Sore Throat, and Fever
Adding a couple drops of lemon essential oil to your glass of water can help soothe a sore throat, calm a cough, and quell a fever. Lemon oil fights against bacteria, as well as viruses. There aren't many substances around that can do both. Many will do one or the other.
Hair, Skin, and Nails
Lemon oil can be used to fight against oily skin and hair. It also has cleansing properties and is often an ingredient in homemade hair products. One thing to keep in mind with using lemon in the hair is that if you go into the sun, the lemon oil might react in such a way that it lightens your hair up a bit. In my experience, this can make for some good highlights, if applied in the right manner. Lemon oil is also great nourishment for the nails and can help fight against nail fungus.
Lemon essential oils are often used in aromatherapy, specifically for anxiety and depression.

To create this helpful blend, use 3 drops of rosemary, 3 drops of lemon oil, and diffuse it with one of the methods mentioned on the AromaWeb website.
