15 Wonderful Benefits of Eucalyptus Oil

The health benefits of eucalyptus oil are well-known and wide-ranging, and its properties include being an anti-inflammatory, antispasmodic, decongestant, deodorant, antiseptic, antibacterial, and stimulating, in addition to other medicinal qualities. Eucalyptus essential oil is colorless and has a distinctive taste and odor.

What is Eucalyptus Essential Oil?

Though eucalyptus essential oil has most of the properties of a typical volatile oil, it’s not very popular as an aromatherapy oil because little was known about it until recent centuries, unlike other ancient aromatherapy substances. The numerous health benefits of eucalyptus oil have attracted the attention of the entire world, and it has stimulated a great deal of exploration into its usage in aromatherapy as well as in conventional medicine.

Eucalyptus essential oil is obtained from fresh leaves of the tall, evergreen eucalyptus tree. The tree, scientifically classified as Eucalyptus globulus is also known as fever tree, blue gum tree or stringy bark tree, depending on where it is located in the world.

Eucalyptus is native to Australia and has spread in the past few centuries to other parts of the world including India, Europe, and South Africa. Though many countries produce eucalyptus oil in small quantities, the prime source of eucalyptus oil for the world is still Australia. Due to the medicinal uses of eucalyptus oil and the compound eucalyptol which is present in its makeup, it is used in a variety of over-the-counter drugs including rubs, inhalers, liniments, rash creams, and mouthwashes.

Health Benefits of Eucalyptus Oil

With so many properties that eucalyptus has, its health benefits are worth knowing. Let’s take a look at them in detail.

Heals Wounds

Eucalyptus essential oil has antiseptic qualities because of its germicidal property. Upon exposure to air, ozone is formed which is a well-researched antiseptic. Therefore, eucalyptus oil is used for healing wounds, ulcers, burns, cuts, abrasions, and sores. It is also an effective salve for insect bites and stings. Furthermore, besides soothing the affected area, it also protects the open wound or irritated area from developing infections due to microbial activity and exposure to air.

Treats Respiratory Problems

Eucalyptus essential oil is effective for treating a number of respiratory problems including cold, cough, running nose, sore throat, asthma, nasal congestion, bronchitis, and sinusitis. Eucalyptus oil is antibacterial, antifungal, antimicrobial, antiviral, anti-inflammatory and decongestant in nature, which makes it a good ingredient in many medicines that treat respiratory problems. A study published in Laryngoscope in 2004 shows its usefulness in treating nonbacterial sinusitis. Patients suffering from nonbacterial sinusitis showed faster improvement when given the medicine containing eucalyptus oil. Gargles of eucalyptus oil mixed with warm water are consistently effective in treating sore throats.

Asthma is a condition that affects millions of people around the world, and there are many known treatments for the condition. One of them is the use of eucalyptus essential oil. Simply massage 1-3 drops onto the chest and the soothing effect of the aroma and vapors will calm the throat and dilate the blood vessels, which will allow more oxygen into the lungs and thus normal breathing will be achieved. The anti-inflammatory properties of eucalyptus essential oil also come into play in using it to get relief from asthmatic symptoms.

Removes Mental Exhaustion

One very important reason that many people use eucalyptus oil is that it creates a cooling and refreshing effect. Normally, people suffering from certain conditions and disorders are slightly sluggish. Eucalyptus oil, a stimulant, removes exhaustion and mental sluggishness and rejuvenates the spirits of people feeling sick. It can also be effective in the treatment of stress and mental disorders.

Apart from mental exhaustion, eucalyptus essential oil is commonly used to stimulate mental activity and increase blood flow to the brain. Since the essential oil is considered a vasodilator, it increases the blood flow around the body by relaxing the blood vessels and allowing more blood to circulate. Basically, more blood to the brain means more brain power, and eucalyptus essential oil is commonly employed in classrooms as a form of causal aromatherapy to increase student performances. Further formal research must be done in this area, but all signs point to the positive correlation between brain function and eucalyptus essential oil.

Relieves Muscle Pain

If you are experiencing joint and muscle pain, massaging eucalyptus oil on the surface of the skin helps to relieve stress and pain. The volatile eucalyptus oil is analgesic and anti-inflammatory in nature. Therefore it is often recommended to patients suffering from rheumatism, lumbago, sprained ligaments and tendons, stiff muscles, aches, fibrosis, and even nerve pain. The oil should be massaged in a circular motion on the affected areas of the body.

Dental Care

Eucalyptus essential oil is very effective against cavities, dental plaque, gingivitis and other dental infections owing to its germicidal properties. This is why eucalyptus essential oil is so commonly found as an active ingredient in mouthwash, toothpaste, and other dental hygiene products.

Eliminates Lice

Due to its well-known qualities as a bug repellent and natural pesticide, it is frequently used as a natural treatment for lice. Some of the mainstream treatments of lice can be very severe and cause damage to the hair, as well as packed with dangerous chemicals that you don’t want being absorbed into your skin. So combine a few drops of eucalyptus oil through a lice-infested head is a much better and healthier solution.

Removes Intestinal Germs

Eucalyptus oil is a vermifuge and is frequently employed to remove germs in the intestine. Studies have shown that ingesting eucalyptus oil can deter many of the bacterial, microbial, and parasitic conditions that arise in the various parts of the body, particularly in susceptible areas like the colon and intestine.

Skin Care

Eucalyptus oil is often applied topically to treat skin infections and it helps speed up healing.

Manages Diabetes

When ingested, eucalyptus oil can help control blood sugar. Its properties as a vasodilator, mentioned above, mean that the entire body benefits from the increase in blood circulation. Diabetic patients commonly suffer from a lack of good circulation, and it can be very dangerous, even resulting in amputation or death. Therefore, it is a good idea to frequently massage eucalyptus oil to the skin topically, and also inhale it as a vapor to ease the constriction of blood vessels. For best results, massage it onto the skin after a shower. The vasodilating and relaxing qualities will benefit diabetics.

Treats Fever

Eucalyptus oil is also used for treating fever and reducing body temperature. This is why one of the common names of eucalyptus oil is “fever oil”. It works well when combined with peppermint oil and sprayed on the body as a mixture of a deodorant and a temperature reducer.

Apart from that, other benefits of eucalyptus oil include the following:

Room Freshener

The antiseptic and deodorant nature of eucalyptus oil makes it a perfect room freshener for hospitals. It also kills bacteria and germs in the air, keeping the environment of the rooms clean and sterilized.

Used as Soap

Eucalyptus oil is frequently used in soaps, detergents, and household cleaners. This is primarily due to its pleasant aroma and effect as a deodorant, antibacterial, antiseptic, and antimicrobial agent.

Treats Tuberculosis & Pneumonia

Eucalyptus essential oil has plenty of antibacterial and antiseptic qualities. When massaged onto the chest and used as a vapor rub or inhalant, it can relieve the signs and symptoms of harmful conditions like tuberculosis by clearing the lungs and reducing inflammation. It is best if applied to both, the chest and the back, over the area of the lungs.

Eucalyptus-OilOral Care

As mentioned above, this oil is a fundamental ingredient in many types of mouthwash and toothpaste. There have been a significant number of studies done on the antimicrobial qualities of essential oils. Eucalyptus essential oil has been shown to protect against microbial growth that can promote a host of different symptoms and diseases in the body.


Many people add eucalyptus oil to baths, spas, and saunas because of its refreshing and antiseptic attributes. Most of the benefits of eucalyptus essential oil can be accessed through the vapor, as well as topical application or ingestion. Therefore, it is commonly used in aromatherapy, which is frequently included in spa treatment packages.

There are many less-researched areas of application for eucalyptus oil, and they should be studied more before being used as completely effective treatments. Early testimonials, however, speak highly of its abilities. It can be applied as a treatment for hayfever (seasonal allergy), acne, endometriosis, and herpes simplex virus.

Usage of eucalyptus oil in aromatherapy is gradually growing in popularity because it blends well with many other essential oils including the essential oils of thyme, rosemary, marjoram, lavender, cedarwood, and frankincense.

Word of Caution: There are some dangers of taking too much eucalyptus oil because when taken in large quantities, eucalyptus oil can be toxic. It may also interfere with other homeopathic treatments. Also, for certain people with allergic sensitivities, eucalyptus essential oil might cause airborne contact dermatitis, which can be very uncomfortable, and even dangerous. Before beginning any new intensive alternative medical treatment, consult your doctor for advice, or have an allergy test done.

Have you used this internally and in what way if you did. I'm suffering from systemic whipples disease and have been trying pine needle oil but too much of it causes me a lot of problems. Wondering if the eucalyptus would be better and less toxic.

I have been using eucalyptus oil for sometime now. I love it and I have seen how it works and how effective it is when I have a cold, flu, or other type of virus.

Has anyone used eucalyptus oil to help with sleep apnea?

I'm wondering if all commercial eucalyptus oils are equally produced and effective?

I heard about it growing up in Ethiopia they put it in boiling water and breath the steam while their head is covered with towel. I just finished using it in hot bath water per my roommate suggestions to get rid of this cold symptoms I have - man talk about sweating, I feel like I just finished running a marathon. He said he brought it from ausiland.

So I had to do research about it while I am covered with sweat laying on my bed and ended up finding this article. Cool stuff, thanks for the info I probably have to utilize it more often. -aK>

who's the author of this article? we need it for our research reference. thank you

One problem with eucalyptus is I am highly allergic to it. I have had students wear it to school and I get bad headaches/migraines. I am sure there are others that have this issue.

High everyone ! A few weeks ago I tried some cannabinoid oil on some aching old joints knee and fingers I was amazed with the healing results so I wanna make some I have found a few recipes but I'm thinking of using eucalyptus as a base oil any comments or suggestions please and thanx

I have never heard of eucalyptus as a base. Certain herbs and spices do not mix well with cannabis oil. Like tumeric for example, because it counteracts it. Usually alcohol, glycerine or coconut oil is a base when making cannabis oil. But I cannot be certain about eucalyptus. I can imagine, because it's expensive to buy large quantities of eucalyptus, that it will cost you. Whereas coconut oil is cheaper in bulk.

DO NOT USE IT AS A BASE......I would take a small ant of CBD and mix in carrier oil like coconut and add a few drops of eucalyptus and see the result.

Great page

considering the fact that i am jamaican we are always looking to mother nature heeling i always use eucalyptus oil and sometimes with peppermint especialy in the winter when my kids have a cold and are congested.thank you all for shearing the natulai truth.

It is also a great tool to have in your arsenal when trying to repel mice. Put a few drops of the oil on cotton balls, then place them where the rodents tend to frequent. Replace every few weeks, or when the smell has dissipated. It can be used in conjunction with peppermint oil.

While this will not rid your home of mice, you will see far less of them. Living in the country, every fall I tend to have a nasty rodent problem. I use the eucalyptus and peppermint oils in addition to trapping and plugging up holes with steel wool.

I want to buy the Eucalyptus oil.pls send me the price.

Putting this in the hot tub along with Lavender works really well to calm down the nerves. I've been doing this for years, and it's awesome.

how much oil and lavender do you put in your hot tub? Maybe you ment a tub of hot water and not a hottub with jets etc. guess I could ask the dealer where I bought the hottub if these ingredients would damage either the tub or filter or motor..anyway, how much is used? I would love to feel better as the gin and tonic isn't doing the trick, totally. Thanks!

Rajesh Srivastava

I have used long ago for acidity related problems. Take one-two drop of eucalyptus oil in sugar( one small spoon). It helps.

I put on some of that eucalyptus rub around my nose and throat. Sure helps me breath a bit better. Right now I am sick and it is helping. Plus the humidifier helps. I think the filter has some in it too.

I have always just used the branches in my house to control fleas. it works great even when they dry out, just keep them lying around either in a vase or leaves in a bowl. never flea problems again.

I'm wanting to put some eucalyptus oil on my 2 year old's feet to help his cough. Does anyone know if it's ok to go outside while it's on? I know your not supposed to with vicks

I was getting on an elevator recently and held the door for this little old lady that was bouncing around alot better then me. I have been sick for about 7 weeks, went through 2 perscriptions, bad case of laryngitis. She said to me as the door closed that she does not know how to dress from day to day because of the severe temperature changes. I said to her I know what you mean in a raspy voice, I have been sick well over a month, blaming the weather. She said to get eucalyptus at my local drug store, boil some water and remove it , and put two or three drops in the boiling water, cover my head over the hot water with a towel and breath in and out. Almost immediately the swelling went down in my throat, my chest opened up and I could take deep breaths, and the need to constantly cough literally became non-existent. I just did this one hour ago and had to write this message. I think the little old lady was my angel, and eucalyptus is one awesome mother nature heeler.

the same happened to me two days ago when I tried it for the first time! it was amazing!!! unbelievable difference it made!

Cheryle Szulczewski

she sure was your angel, hope you continue to feel better
