From the myrtle family (Myrtaceae), Eucalyptus L'Héritier 1789 is a diverse genus of flowering trees and shrubs. Members of this genus are dominant in Australia and include Eucalyptus regnans, which is the tallest known flowering plant on Earth. The indigenous people of Australia have used eucalyptus oil for centuries to relieve everything from common aches and pains to cold and flu symptoms.
There are more than 700 species of eucalyptus growing in the world, with the vast majority grown in Australia. The first production of eucalyptus essential oil began in 1852 in Victoria, Australia. By the turn of the 20th century, it was well established and eucalyptus oil was being exported to many countries. Over the next 50 years, this distinctively Australian industry was the major supplier of eucalyptus oil all over the world.
The oil is extracted by steam distillation, which separates the essential oil from the dried eucalyptus leaves. That extracted oil is used in countless health-related treatments and products.

In terms of application today, eucalyptus oil is used in insect repellent (Lemon eucalyptus), as a disinfectant, for asthma treatment, and other uses too numerous to mention here.
Many use a eucalyptus oil base as a shaving soap and aftershave balm, as it both prevents and soothes the irritation of razor burn. But that's merely the tip of the iceberg for this multi-purpose oil.
Before we begin, however, let's learn a little more about these amazing plants.

Cool stuff, huh?
Below are 15 ways the various species of eucalyptus essential oil can be instituted into your health routines. There is no doubt this amazing oil helps make people’s lives better every day.
1. A Natural Cough Suppressant
For over a century, people in the western hemisphere have been using eucalyptus oil to treat coughs and upper respiratory irritation. Most cough drops on the market today contain a small concentration of eucalyptus oil to scratch that tickling itch in your throat. The vapors produced by eucalyptus oil work to soothe irritated nerves in your respiratory tract as well as acting as a numbing agent.
As a testament to the power of eucalyptus oil as a cough suppressant, Vick's VapoRub, an over-the-counter topical mentholated ointment, uses a 1.2% concentration of eucalyptus oil.
*Due to some of the constituents within eucalyptus species, it is not recommended for internal use. Piperitone is an example of a constituent, that, when ingested can induce vomiting and diarrhea. (1)
The following recipes will soothe your throat and ease your cough along with having the wonderful properties as an anti-viral and anti-bacterial. Since we avoid using eucalyptus internally, we’ve included an inhaler with Eucalyptus citriodora.
After turning off honey, add essential oils, pour in a glass bottle, and seal immediately. Will keep 2- 3 months.
*Note: For children under 5, replace Peppermint with Spearmint Mentha spicata (Buy it here).
*Because of infant botulism, it’s advised against giving honey to children 1 and under. I did not give it to my children until 2 years of age. Children that are 2 years and older develop helpful bacteria in their intestines, which act as a defense against the harmful spores that can cause infant botulism.
Add, inhale as needed.
2. Cold and Flu Relief
One of the greatest benefits of eucalyptus oil is its function as an expectorant. Whether you are still suffering from the cold or flu or remnants of it, an expectorant will help to clear out the left behind mucous build up. An expectorant works to release sputum, phlegm, and mucous from our airways.
Dr. Jean Valnet speaks of how one must take a strong antibiotic “from three to upwards of twenty days - and this would be for a feverish condition, straightforward bronchitis or simply nasal catarrh. The essences of eucalyptus would have dealt with such conditions in a matter of 24-48 hours - 8 days at the most for the stubborn cases.” (2)
For daytime or night relief, the following will open your airways to make sleeping more comfortable. The sweet marjoram, frankincense, and vetiver will help you rest more peacefully since these oils also are calming and sedative to the CNS (central nervous system). Vetiver is also known for its support during grief or sadness because it really puts you in a peaceful state of mind.
Cold and Flu Symptom Relief Chest Rub
Leave out the cream and use this blend to diffuse.
*Note: To avoid possible neurological side effects, Robert Tisserand suggests diffusing at no more than 30-minute intervals, with at least 10-minute breaks. For children 5 and under, direct diffusion is the biggest concern. Direct diffusion includes inhaling oils from hands, on a cotton ball, in a steam, or through the use of inhalers. (3)
Alternatively, you can use eucalyptus using a simple steam technique. Steam is a great way to open clogged passages and the respiratory system. Avoid oils that are hot or spicy, such as nutmeg or black pepper. You’ll need a few supplies to prepare. Use no more than 1-2 drops, either alone or in the following blend. There is no need to use more than suggested amount to achieve end results.
Heat a quart of water on the stove to boiling point but DO NOT BOIL. We just want it hot. Transfer to a ceramic bowl. Add chosen oil/oils, close your eyes, cover head with a small towel, and breathe in the steam.
You can do this up to 10 or more minutes, taking breaks in between. Once the water is cool, uncover and let it sit to cleanse the air. The following blend can also be used in a steam:
The following stock blend is exceptional:
Using 1-2 drops, you are now ready for your steam. Store your remaining stock blend in a cool dark place to preserve the shelf life of the blend.
3. Hair and Eucalyptus
Shampoos and soaps made with eucalyptus are wonderful for stress relief and soothing sore muscles in your neck and shoulders. One way you can use eucalyptus essential oil is to make your own hair and skin lotion. However, most are irritants so choosing a skin-friendly eucalyptus is imperative to avoid irritation. Another thing to consider is the maximum percentage that can be topically used safely, yet effectively. At 2% and above, eucalyptus was irritating to various subjects (4). For this reason, we’ve stayed at a safe 1% or less.
Whenever using oils that have possible irritation to skin, use them along with skin-friendly oils to help ease the possibility of irritation. I’ve chosen helichrysum for its cicatrisant (skin healing) properties and patchouli for its wound healing properties and ability to ease scalp irritations. They compliment eucalyptus nicely in skin blends.

4. Sinus and Allergies
For sinus and bronchial infections, we go with Eucalyptus odorata. When eight eucalyptus essential oils were tested in a study, Eucalyptus odorata stood out amongst the others. The cytotoxic effect and the antiviral activity varied significantly within eucalyptus species oils. E. odorata showed the strongest activity against several strains including S. aureus, H. influenzae, S. agalactiae, and against all the tested fungal strains. For further details, see reference. (5)
Use with other oils that have similar properties can help ease symptoms and discomfort from sinus inflammation and swelling.
Do the following:
5. Household Use
Because of Eucalyptus globulus’ strong anti-bacterial actions and antimicrobial properties, it’s a good addition to your cleaning products. You can blend 1-2 drops into a tablespoon or so of pine oil, then add to your water to wipe down your counters and mop your floors. It’s refreshing and keeps us healthy.
*Caution though! If you have pets or small children, we discourage using essential oils in cleaning supplies since their respiratory and neurological systems are much weaker than ours.
6. Insect Repellent
Recently, the Center for Disease Control (CDC) released a report on the use of lemon eucalyptus oil in insect repellant products. (6)
I’ve personally experienced its success in a blend. We had a wedding of 300 hundred in August in Louisiana, the land of mosquitoes. On our country property next to the mosquito loving lake, with the following blend, we danced into the night and not a single guest had concerns of mosquito bites. It is child safe and effective.
Apply to exposed skin to head off mosquitoes. Application lasts 4-6 hours.
