Eucalyptus… you likely know that it is the main food of Australia’s cute koalas, and that it can be found in many cold and flu remedies, but what else do you know about it? Read on to discover some of the remarkable healing qualities of eucalyptus essential oil, together with the latest research on it’s health-boosting and protective properties.
Belonging to the myrtle plant family Myrtaceae, the word “eucalyptus” comes from the Greek word “eukalyptos” meaning “covered” or “wrapped.” This refers to the woody seed pod of the eucalyptus tree which dangles down from the branches and almost completely covers the eucalyptus blossoms. There are well over 900 different species of eucalyptus, both trees and shrubs.
Most eucalyptus species grow in Australia. In fact 75% of trees in Australia are some variety of eucalyptus. They are also found in Indonesia, New Guinea, South Africa, California, and are being cultivated in many other tropical and subtropical regions as well.
One of the best times to be in a forest of eucalyptus breathing in its heady aroma is during the summer when the sun’s heat releases the oil from the leaves. In fact, if you stand on a hill overlooking a eucalyptus forest, you will notice a sort of blue haze hanging over it. That blue haze is the oil being emitted from the trees (which by the way are among the tallest on earth)!
How Eucalyptus Essential Oil is Made
Eucalyptus essential oil is steam distilled from the leaves of the trees. It takes about 50 pounds (22.6 kilograms) of eucalyptus leaves to yield one pound (453 grams) of essential oil.
The most commonly used eucalyptus varieties for aromatherapy purposes have traditionally been Eucalyptus globulus and Eucalyptus radiata. But science is discovering that dozens of other varieties of eucalyptus have excellent healing qualities as well.
Ancient Aboriginal Uses of Eucalyptus
Australian aboriginal people have a history dating back tens of thousands of years and they used eucalyptus extensively for healing. They bound the leaves around serious wounds to prevent infection and promote healing. They knew the fresh, lung-opening aroma to be excellent for clearing respiratory congestion, and that it helped to suppress coughing.
They used eucalyptus to repel the ever-present outback flies and insects, and employed eucalyptus as a rub for sore muscles, joint pain, and headaches. Sometimes they would burn the leaves and inhale the smoke to relieve a fever. Even the resin of the eucalyptus tree was collected, boiled, and used as a disinfectant for treating cuts, sores, and other painful conditions.
Other cultures use eucalyptus as well. For instance, traditional Chinese and Indian medicine employed the use of eucalyptus for a wide range of medical conditions.
How Eucalyptus Essential Oil Was Brought to the West
In 1848, Joseph Bosisto, a young pharmacist from Yorkshire, England, arrived in Australia thinking he was going to take part in the Victorian gold rush. Instead, he began to investigate the healing properties of Australian plants − specifically eucalyptus. In 1852 he began distilling eucalyptus oil, making it one of the oldest commercially available oils. Eucalyptus oil became a highly sought-after medicinal oil; it even won prizes in 17 international exhibitions in 1891!
Eucalyptus was used extensively during both World Wars. It was used to control meningitis and influenza outbreaks, and to cleanse wounds when other anti-bacterial supplies ran out. In the 1940s and 50s many cold and cough medicines contained eucalyptus oil for it was widely known then for its ability to ease those conditions.
Potent Phytochemicals Found in Eucalyptus
There are over one hundred potent phytochemicals (natural plant-based chemical compounds) in eucalyptus oil. The phytochemical content varies between eucalyptus varieties and chemotypes. Some plants generate different chemical constituents within a genus and the chemotype denotes this difference.
Sometimes the distilling process employed creates different phytochemicals. Some of the main compounds in eucalyptus essential oil include citronellal, aromadendrene, alpha-phellandrene, beta-phellandrene, alpha-pinene, beta-pinene, piperitone, (E)-methyl-cinnamate, para-cymene, gamma-terpinene, 1,8-cyneol (eucalyptol), geraniol, geranial, and many more.
Extensive Research into the Many Health Benefits of Eucalyptus
A Safe Alternative to Insect Repellent
In 2012, Argentinian researchers investigated 15 different species of eucalyptus and found that they all had the ability to kill the larvae of the mosquito that causes Yellow Fever, Aedes aegypti. In 2011, some of those same researchers reported in the Journal of Economic Entomology that several varieties of eucalyptus oil were toxic to Haematobia irritans, better known as the blood-sucking horn fly.
In 2009, UK researchers published a study in Experimental & Applied Acarology investigating four eucalyptus species. They found that they were toxic to the parasitic red chicken mite, Dermanyssus gallinae. Researchers made an interesting note, stating “There appeared to be a trend whereby the essential oils that were composed of the fewer chemical components were the least lethal to D. gallinae. It may therefore be the case that the complexity of an essential oil’s chemical makeup plays an important role in dictating the toxicity of that oil to pests.”
A 2009 article appearing in Science for Environment Policy discussed the interesting possibility that eucalyptus oil might prove to be a great alternative to chemical pesticides due to its natural ability to repel insects, microbes, and fungi. Also, essential oils do not persist for long in the environment as do chemical pesticides.
Eucalyptus Displays Strong Anti-bacterial Effects Against Staph & MRSA
Dozens of studies exist which attest to the ability of eucalyptus to kill many different strains of bacteria. Here are some of the most interesting studies:
2014 Indian research reported in Ultrasonics Sonochemistry found that a specially prepared nanoemulsion containing (in part) eucalyptus oil not only effectively killed Staphylococcus aureus (better known as golden staph) in an animal study, it also improved wound healing time.
A German study reported in 2011 in the journal Pharmaceutical Biology found that among the eucalyptus varieties studied, Eucalyptus globulus had the strongest activity against methicillin-resistant Staphylococcus aureus (better known as MRSA, currently rife in hospital settings).
In 2008, Italian researchers investigated Eucalyptus globulus essential oil and found it to be active against Haemophilus influenzae. This is a type of bacteria that mainly causes illness in babies and young children, more commonly known as H. influenzae type b, or Hib. This oil was also potent against H. parainfluenzae (involved in COPD), and against Stenotrophomonas maltophilia, a multi-drug resistant bug causing rampant and difficult to treat infections. In addition, it was potent against Streptococcus pneumoniae, involved in many illnesses including pneumonia.
Antiviral Activity Against E. Coli, Staph, Candida, and Herpes
Researchers in Tunisia released a 2012 study in BMC Complementary and Alternative Medicine which found that several varieties of eucalyptus oil had strong antibacterial, antifungal, and antiviral effects against common pathogens. Included amongst these are: E. coli, Streptococcus pneumoniae, Staphylococcus aureus, Candida albicans, and several others.
German researchers in 2001 investigating the antiviral activity of tea tree oil and eucalyptus oil found that both exhibited significant inhibition of both herpes simplex virus-1 and -2.
Anti-Inflammatory and Beneficial for Respiratory Disease
Science is discovering what ancient people have long known − that eucalyptus has the ability to aid respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, bronchitis, the common cold, croup, influenza, and pneumonia. It appears to do this with the help of four potent phytochemicals (and there well may be more):
- Eucalyptol (aka 1,8-cineole). It helps to ease the inflammatory process, according to German research investigating its properties in inflammatory airway diseases. 2016 research released by Chinese scientists, reported in the journal Inflammation, also found that 1,8-cineol effectively stopped pulmonary inflammatory processes and protected against influenza viral infections in an animal study.
- Pinocembrin. Joint Australian and American research published in 2016 in the journal PLoS One has hit upon another fascinating phytochemical from certain varieties of eucalyptus: a flavonoid known as pinocembrin. It also has potent anti-inflammatory properties. Indeed, 2015 Chinese research also found that pinocembrin played a central role in inhibiting the inflammatory process.
- Gamma-terpinene. 2015 Brazilian research published in Planta Medica found that gamma-terpinene derived from eucalyptus alleviated acute inflammatory responses in animals.
- Ellagitannin. Egyptian research reported in 2015 in Phytomedicine indicates that a polyphenol known as ellagitannin from Eucalyptus citriodora had gastro-protective effects on rats with stomach ulcers due to its antioxidant and anti-inflammatory benefits.
Eucalyptus Essential Oil Helps to Regulate Blood Sugar
Many different cultures have used eucalyptus to help regulate blood sugar levels. Modern research is finally confirming that benefit.
Colombian researchers reported in 2015 that Eucalyptus tereticornis extracts increased glucose uptake in vitro (test tube study). Further, in diabetic mice this variety of eucalyptus reduced fasting glycemia, improved glucose tolerance, and reduced insulin resistance.
A 2014 joint research project published in World Journal of Diabetes found that the polyphenols and flavonoids in three eucalyptus species inhibited enzymes that played a role in type 2 diabetes. Eucalyptus globulus was the clear winner in this in vitro research study.
An Iranian research study published in 2009 in the Indian Journal of Clinical Biochemistry on diabetic rats found that the antioxidants in Eucalyptus globulus, after four weeks of administration, caused a significant decrease in plasma glucose levels.
Pain Relief and Reduced Blood Pressure
A 2013 Korean study reported in Evidence-Based Complementary and Alternative Medicine tested the effect of eucalyptus oil on pain relief with 52 patients who underwent total knee replacement surgery. The patients were divided into two groups. One group inhaled eucalyptus oil, while the control group inhaled almond oil. The eucalyptus oil group reported much lower levels of pain than those inhaling the almond oil. Also, the eucalyptus oil group enjoyed significant reductions in blood pressure.
Novel Japanese research reported in 2012 in the journal Molecular Pain found that 1,8-cineole from eucalyptus had analgesic and anti-inflammatory effects. This was due to its inhibition of something known as TRPA1, which is a thermosensitive receptor in humans.
Does Eucalyptus Essential Oil Have Anti-Cancer Benefits?
The phytochemicals alpha-pinene and beta-pinene (found in some varieties of eucalyptus) have been discussed at length for their anti-cancer properties, but many other anti-cancer compounds derived from eucalyptus are currently being researched.
2014 research from Jordan investigated six species of eucalyptus and found weak to moderate activity against non-lymphoma tumor cell lines. They also found potent cytotoxicity (meaning toxic to cancer cells) against lymphoma tumor cell lines.
Joint Saudi and Egyptian research reported in 2014 in Scientific Reports on extracts from Eucalyptus cinerea demonstrated they had moderate to potent cytotoxic activity against three human cancer cell lines. These include MCF7 breast cancer cells (hormone receptor positive cells), laryngeal carcinoma, and colon cancer cells.
2012 research out of the University of Rajshahi, Bangladesh, found that several varieties of eucalyptus reduced tumor growth rate and enhanced the lifespan of the mice in the study.
Eucalyptus may have a role to play in cancer, but more human studies need to be done.
Eucalyptus May Stimulate Immune Response
According to a study published by Italian researchers in 2008 in BMC Immunology, Eucalyptus globulus activated human monocyte derived macrophages, a part of cell-mediated immune response. The researchers also found that the immune systems of rats given a combination of eucalyptus oil and 5-fluorouracil (5-FU), a popular chemotherapy drug used in the treatment of different types of cancer, fared much better, nearly as well as untreated rats.
The researchers went on to state, “Thus, the present study stimulates further investigations also using single components of essential oil extracts from various species of Eucalyptus for development of a possible new class of immuno-regulatory agents useful as adjuvant in immuno-suppressive pathologies, in infectious disease as well as in tumour chemotherapy.”
Even More Health-Promoting Uses for Eucalyptus
Even More Health-Promoting Uses for EucalyptusFighting Fever – Eucalyptus has long been known by native Australians as the “fever tree” because of its ability to help reduce a fever. Studies dating back to 1891 in The Lancet indicate eucalyptus oil was being used for scarlet fever.
Improved Brain Function – While there does not appear to be much formal research on the subject, eucalyptus essential oil has a long tradition of being used to stimulate mental activity. 2005 research out of Brazil, published in the Brazilian Journal of Medical and Biological Research, discusses the fact that eucalyptus is a vasodilator. This means it increases blood flow by relaxing blood vessels. That allows increased blood flow to various parts of the body, including the brain. More blood to the brain means better, clearer thinking. Eucalyptus has often been used in classrooms to increase student thinking and performance.
3 Ways to Use Eucalyptus Essential Oil
It’s best to purchase your eucalyptus essential oil from reputable companies that use proper distillation procedures and ensure a quality product. They should also indicate the genus species on the label (for instance Eucalyptus radiata or Eucalyptus bicostata or Eucalyptus globulus) so that you know exactly what you’re buying.
1. Inhalation. Eucalyptus provides instant relief for upper respiratory infections. Place a few drops of oil into your palms, rub them together, and place them over your nose and mouth (being careful to avoid the eyes). Breathe in deeply for a few minutes. This is the best method for getting the essential oil into your bloodstream so it can do its job. You can also diffuse eucalyptus in the room where you are working or sitting. Use a cool mist ultrasonic diffuser for best results. Do not heat essential oils as this can diminish their therapeutic benefits.
2. External Application. Using an organic carrier oil such as almond, jojoba, hemp, coconut, olive oil, etc, dilute and massage eucalyptus oil into the skin. You can also place a few drops of eucalyptus into one cup of epsom salts. Dissolve this mixture into a hot bath and soak. It’s great for sore muscles and also soothing for urinary tract infections.
3. Internal Application. Eucalyptus essential oil has been approved for human consumption by the United States Food & Drug Administration (USFDA). Eucalyptus globulus is the best one to take internally. Put a drop or two of Eucalyptus globulus in three to four ounces (about 100 ml) of liquid such as almond or rice, or soy milk. A few drops can also be added to one teaspoon of raw honey. Be sure to read “Precautions for Using Eucalyptus Oil” below before using internally.
Precautions for Using Eucalyptus Oil
Be sure to use a high quality, medicinal grade essential oil. Use of eucalyptus essential oil is not recommended for:
- Pregnant or nursing women
- Children under age six. In older children, be sure to dilute heavily.
- It can be dangerous to take high doses of eucalyptus oil. Always work with a qualified aromatherapist or health care practitioner.
- Eucalyptus can irritate those with sensitive skin. Be sure to dilute prior to using on sensitive areas such as face, neck, etc and always do a patch test first with a carrier oil before applying liberally.
It is not advisable to use any essential oil as a stand-alone therapy for cancer, or for any of the other health issues mentioned in this article. When used in combination with other conventional and complementary medical treatments, however, essential oils can be effective in helping the body heal… as well as protect against a number of health-harming pathogens.
wow – amazing! I love Eucalyptus oil & have used it mainly for respiratory stuff…. THANK YOU for the many other ways I can enjoy it! much love & light, Brenda
As a practising Aromatherapist for many years I found this article really interesting. Thank you. I couldn’t get linked to your website though when I tried.
Thank you so much Ty for your dedication to educating the masses on how to take control of our health, for challenging the main stream thinking, and providing alternatives to the profitable medical practices (that actually compromise our health.) You have no idea how you are changing the world!!! Thank you, Thank you, Thank YOU! And may God bless you and keep you and your family safe and healthy!
After using 100% Deet as a bug deterrent for years I noticed it ate through my vinyl canoe seat. After this happened I quit using it. I found a product that was made from Eucalyptus oil and starting using that. It turned out to be the best product I ever used to avoid mosquitos and black flys. They still fly around you but they do not land and bite you.
Upon arriving in the foothills of the Andes for a 6-week vacation, I was overcome by altitude sickness that included an acute upper-respiratory infection. This went on for 3 weeks, and I tried several medications to no avail. During the second week there, I realized that there were eucalyptus trees growing all around my friends’ home. I gathered the leaves, placed them in a pot of boiling water and steamed my nasal passages and sinuses by placing a large towel over me head and the pot, to keep my face in the steam. Admittedly, I had to do this for several days before the infection was cured, but it did cure me. Eucalyptus oil saved my life (or so I thought because I was sure I was going to die there), and I was able to enjoy the next 3 weeks of my vacation! Im definitely a believer in it’s antibacterial properties!
One more example of Nature’s medicine working for us.
Thank you, for sharing !
hello Ty, i love eucalypus oil but have been told that if you have pets to be careful, its ok for dogs but can be toxic to cats? ive got both at my house so id like to know if this is true, id like to be using it again, evidently there is eucalyptus radiata and other ones, does that make a differnce for pets ? thanks so much Lydia
Had to share this on FB very good information.

I love Eucalyptus Oil. When I feel a cold coming on, I immediately rub it on my sinus areas, throat, neck and my lung areas. By the next day, no more feeling like a cold is invading my body.
I inhaled Eucalyptus oil everyday when I was pregnant. It helped with my sinus problems. I boiled water with a few drops and inhaled. Or I diffused it and inhaled.
What oils do you recommend for m.s.
As a Holistic Doctor with one speciality in Certified Essential Oil Therapy, I would respectfully suggest that you identify both the genus and the sub-species of the plants used to produce the oils that you promote. Many different sub-species of plants and varieties of resins, metals are used in essential production to target various imbalances etc.. Each sub-species targets specific diseases, parts and areas of the body, physio-psycho-emotional imbalances and diseases, organs, aspects of organs, conditions of ‘dampness’–a precursor to disease, most prominently cancer–and ‘dryness’ etc., various soft-tissue and bone conditions/pathologies, and so on (e.g. the ‘Pine oil’ to which you refer of which there are many sub-species–some much more efficacious than others; all targeted differently and with altering profiles).
To do something like recommend generic pine oil is unprofessional and I’m thinking you may not want to be promulgating incomplete information which could result in negative impacts. In my experience, most people using and recommending essential oils know just enough to be dangerous and not enough to diagnose, treat efficaciously, prevent disease, and identify contraindications which more often than not can only be determined by an experienced practitioner.
Experts in essential oils (which have their 14,000 year origins in Ayurvedic Medicine–the oils, not the experts) perhaps ought to be given authority in this aspect of your dissemination of healing knowledge. Essential oils are very powerful and complex healing modalities and a great deal of training is required to use them in appropriate, safe, and targeted ways. If used without sufficient knowledge there is considerable danger in the use of certain oils.
In addition, I would like to suggest that it is vital for your followers to understand that many–in the US perhaps the majority–of essential oils are produced using benzene which is extremely toxic and carcinogenic. There are other equally noxious chemical means by which essential essences are rendered. The two safest, most common, processes by which most oil may be extracted while preserving its integral power, are CO2 extraction and distillation (sometimes steam, sometimes not). Expression, cold-pressing (used for citrus oils and other oily substances), and ethyl alcohol extraction are also used but less commonly. Resin ‘tapping’ initiates the extraction of myrrh, pine, spruce, fir, frankincense, and other resin oils, In addition, the various ‘clean’ extraction processes produce oils of differing natures. For instance, ginger oil extracted using CO2 treats a different symptom/disease profile than ginger having undergone distillation.
These are a few examples of the complexity of essential oils and a few reasons why they are not appropriate in the hands of insufficiently knowledgeable people who are touting their benefits or perhaps even treating patients.
Things are burgeoning in your world. Information overload in our current culture/civilisation is creating a snowball effect in terms of both allopathic and wholistic health practice. I’m sure you’re cognisant of the increasing ease with which false information may be disseminated widely.
Mr. Bollinger, bless you from every path to God for the work you and Mrs. Bollinger of course, too.
Many congratulations on your book!
I remain your faithful follower,
Yours Very Truly,
Leigh Currier
P.S. Essential oils that are not labelled with the correct binomial nomenclature ought to be deemed suspect, to be on the safe side. Without accurate identification, the profile of the oil is not fully known and can not be targeted accurately by either practitioners or lay users. It indicates also, to my mind, patently, lack or suppression of knowledge on the part of the manufacturer.
These powerful and elegant extracts are sacred and require most respectful use.
Thank you.
Leigh Currier
Oops! Typo!
“Mr. Bollinger, thank you from every path to God for all that you and Mrs. Bollinger do.”
Please amend if you intend to post.
Cheers.
PPS It’s just occurred to me that, if you would find it useful, I’d be most happy to write an abstract or paper on the basics of essential oil history, extraction, application and other pertinent info. that could be used for your own edification and perhaps as an info piece to disseminate as you see fit.
If you require a CV, I’m glad to oblige.
Thank you.

I’m not convinced even one drop eucalyptus should be placed in the palms and inhaled before diluting with a carrier oil. Correct?
Very interesting artical …
I’m an Australian and have been using eucalyptus oils all my life and agree with everything you have said. Whenever I catch a cold I always put eucalyptus on the corner of my pillow at night, this helps you breathe while asleep and you usually feel much better in the morning. Thank you for all the articles you send to us they are much appreciated. Thank you again. Natalie
It is safe to do so or you can put the oil onto a tissue or handkerchief and inhale it that way. Alternatively you can do steam inhalation or use a vapouriser.
Thank you for that Lorraine as I don’t have a diffuser or vapourizer. I did read on on this article that you can put a few drops on your palm & rub to inhale that way….
I ordered and paid for 3 books on September 23. Please respond. Thomas Wenrich
Hi Thomas,
Thank you for your comment.

You shared a lot of interesting information with us. Thank you.
I first read about eucalyptus oil in the 1990’s when an ad mentioned how Australian hospital used it during WW1 in hospitals so they would not get sick from the great influenza epidemic at that time. I then began using the oil whenever I came down with a cold. I shared this information with a psychiatrist on our staff and he immediately ordered several bottles for his family and he has been using the oil ever since. It was surprising and gratifying to witness a medical doctor embrace this natural remedy. I just noticed you have an article on pine tree oil. I first used that in the form of Thuja Oil about 40 years ago when I read that it could heal warts. That claim proved to be true in my case. Those warts on my fingers never returned after being dissolved from applying Thuja tincture to them. The only known source for that oil back then was the Washington Homeopathic store in Wash., DC.
Yes, I lived in Melbourne, Australia in the early 70s and Always had in my family cabinet a bottle of Eucalyptus Oil for so many uses to many to mention. I remember driving in this road called the Eucalyptus Tunnel road with some Koala Bears eating the leaves, which made them sleepy….Now in my Seniors years I still have a bottle of Eucalyptus Oil in my cabinet in Toronto, Canada, for different uses, some good habits are never forgotten!!!!
Thank you Ty Bollinger for all your research.

Use with children, here “In 2008, Italian researchers investigated Eucalyptus globulus essential oil and found it to be active against Haemophilus influenzae. This is a type of bacteria that mainly causes illness in babies and young children, more commonly known as H. influenzae type b, or Hib.
Then here, Precautions for Using Eucalyptus Oil, says not to use with children.
Can we use it with kids or not? (above average height and weight, almost two year old)
diffuse or ?
Yes, I hope we’ll get some clarification on this. Plant Therapy, a supplier of quality oils, has “Kid Safe” products. You might check those out.
How long has this essential oil company been around? I only trust one brand and that is Young Living. They have been providing the highest quality oils for over 20 years. They have more than earned my trust by being the only essential oil company with a seed to seal promise of the highest quality. They welcome visitors to their farms to see first hand all the steps to providing the best therapeutic oil available.
Hi Julie,
Please contact Epigenetic Labs for more information: https://support.epigeneticlabs.com/submit_ticket
I have also been following and using Young Living Essential Oils for almost 20 years with numerous positive results for myself, family, friends etc. and the YL Company has more than earned my trust as well. The seed to seal promise of highest quality oils speaks for itself. Of course, since I trust Ty and the courageous and wonderful work he has done, and is doing for us all. Obviously ‘epigenetic’ comes highly recommended
Unless one is a scientist and is comparing each company side by side, how would one know?
I am diffusing Young Living Eucalyptus Globulus as I type. I too have been using these oils for over 20 years. Exceptional oils with integrity. A friend shared a nice way to breath Eucalyptus in without putting Eucalyptus on the skin. Try this. My daughter and I do this when feeling sinus or respiratory compromises. Put a organic cotton ball or two inside a sterilized empty spice jar and drop aprox. 15 drops of Eucalyptus Globulus, our favorite Eucalyptus. Close it up aprox . 10 min before using .Breath in the vapors and use through the day. Just add more drops when necessary. Easy to take with you too. Enjoy. Also, Thyme oil or dried herb is excellent for respiratory issues. Do your research to find the best method for your individual situation. Best Healing to all. Caution. I would not breath in thyme. There are very special ways to use essential oils. One must do research and or ask one with good experience.
Your text confirms our findings that Eucalyptus can and is being used internally. Why then did you say it should not be used internally. Please do not be timid when you know the truth; SAY IT LOUD.
Eucalyptus tea can also raise blood pressure that was lowered by olive leaf extract. It was recommended to me to counter-act the pressure lowering affect of olive leaf extract. Too low blood pressure had to be avoided in this pneumonia situation and it was obvious through constant monitoring that the eucalyptus leaf tea was doing that.
