7 Surprisingly Practical Uses For Eucalyptus Oil You Need To Know

uses for eucalyptus essential oil

While I enjoy the smell of essential oils wafting out of my diffuser as much as the next person, I’ve always been more interested in their practical applications. A lot of people still don’t know how useful essential oils can be to have around the house, but I’m hoping that today’s blog post will help change that! :-)

While I’ve already written about a wide variety of uses for lavender, lemon, peppermint, tea tree, and geranium essential oils, I have yet to give eucalyptus oil its turn in the spotlight. But that is about to change, because it’s time we all got to know these 7 practical things you can do with eucalyptus essential oil!

7 Practical Uses For Eucalyptus Oil

1. Alleviate Headaches

Eucalyptus essential oil can help ease the pain and tension of headaches caused by sinus pressure, stress, and exhaustion. Add 5 drops of eucalyptus oil to your diffuser, or apply it topically by putting a drop or two on the back of your neck.

2. Fight Lice

According to the results of a 2017 study, eucalyptus oil showed promising results as a treatment for lice. A solution containing eucalyptus and tea tree oil was 100% effective against lice and eggs after a single application in a randomized trial.

To fight lice, mix 2 ounces of olive oil with 15-20 drops of eucalyptus oil and apply the oil mixture to the scalp. Cover and leave it on for at least 12 hours, then comb, shampoo, rinse, and shampoo again.

3. Erase Plaque

Eucalyptus oil can be a helpful tool in the fight against plaque! A small 2009 study found that an herbal toothpaste containing eucalyptus effectively improved gingivitis and reduced plaque buildup.

Give your favorite toothpaste a boost of herbal plaque-fighting power by adding a tiny drop of eucalyptus to your toothbrush before applying toothpaste. Brush as normal, then rinse your mouth thoroughly.

4. Deter Rats

Have you spotted rats in or around your home? Use eucalyptus oil to deter them from hanging around!

A 2014 study found that rats largely avoided eating in areas that had been treated with eucalyptus oil. You can use this effect to your advantage by adding drops of eucalyptus oil to cotton balls, then placing the cotton balls in areas where rats have been spotted.

5. Relieve Allergy & Cold Symptoms

Eucalyptus oil can help you find relief from mild respiratory symptoms associated with allergies and the common cold. Eucalyptus helps to open airways and improve circulation, improving symptoms like runny/stuffy noses, mild coughs, and even sore throats.

To help relieve allergy or cold symptoms, diffuse 5 drops of eucalyptus oil in your diffuser, or add 2-3 drops to a small amount of carrier oil and rub the oil over your chest and throat. (Or try making your own homemade “vapor rub!”)

6. Relieve Soreness

The anti-inflammatory effects of eucalyptus oil make it a useful natural remedy for muscle pain and soreness. In a 2013 study, patients who inhaled eucalyptus oil while recovering from knee replacement surgery reported lower pain scores than those who didn’t.

But don’t worry, eucalyptus oil is just as useful for treating everyday aches and pains! Just apply 2-3 drops of the oil to the affected area, adding a 1/2 teaspoon of a carrier oil to help cover a larger surface area.

7. Soothe Irritated Skin

Eucalyptus oil has several properties that can help soothe irritated skin, including antimicrobial, antiseptic, and anti-inflammatory effects. Add 2-3 drops of eucalyptus oil to a cotton ball, then swipe it over minor skin irritations (such as shallow wounds, bug bites, blisters, etc.) to promote quick healing.

Bright Ideas

  • I sleep with CPAP, and sometimes I put a couple of drops of lavender essential oil on the filter, which really helps me sleep. This time of year I have a really bad time trying to sleep because of allergies, sneezing etc. I’m going to try eucalyptus on the filter and see if that helps! Anyone that sleeps with CPAP will tell you how difficult it is to sneeze and have a plugged up nose while using a CPAP machine!

  • I put a few drops of Eucalyptus Oil in my Dove shampoo and it cleared up my dry scalp. I had some scaley dry spots some larger than others. I just wash my hair a couple of times a week with it and it works great.

    • Interesting – I wondered about using this for dandruff but from what I’ve read it’s not considered effective; or maybe at least not as much as say, tea tree oil. But maybe this is a different type of condition(?)

  • Please be careful with Eucalyptus Oil, although it is generally regarded as safe, it classed as a poison in Australia, it can be toxic to cats, dogs and children in quite small doses. Pregnant women should avoid it, so should anyone with Epilepsy.

    • I have been using eo’s for years I also have two dogs and a cat. I make my own. Dog shampoo with eucalyptus in it plus others. The eucalyptus gets rid of fleas, it really does!

      • Consider yourself LUCKY…purely lucky and I hope that your luck doesn’t suddenly, and without warning, change! You do realize that if your dog has fleas, you have fleas in your home and until you address that issue, you will be battling the problem indefinitely. Also, MANY of the oils in this category ARE very toxic to animals, and in fact, that’s the leading cause of tremors in cats. Your dog, luckily, must be large enough to handle the amount you have used. But we should NEVER assume or insinuate that what works for one is good for another. In fact, it may be death for another animal!

  • You mention carrier oil in your article – I am new to all this – could you pls explain what “carrier oil” is? Many tks. Always enjoy your helpful hints.

    • Carrier oil is any oil used as a carrier for the essential oil. There are very few essential oils that can used neat, they are extremely strong. So a bland oil, such as almond oil, is used to dilute the essential oil to the correct dosage

    • Hi, Helen. The carrier oils I have available in my “arsenal” :-) are coconut (solid form and liquid), avocado, grapeseed, almond, apricot, argan, pure shea butter and I use castor oil for some things but not as a carrier oil. All it is supposed to do is be a buffer to dilute essential oils so that they aren’t so strong on the skin. Knowing that you can sort of use your own judgment. Hope I was some help! I recently got into EO’s in a big way so I have done a lot of research and learned as I go…REALLY fun!! If I can help you again, just send me a note through this! God bless! :-)

  • I read years ago that if you add it to your laundry it can kill the dust mites that are on bed linen. I usually add some to a little bit of fabric softener to sheets when I wash those. I don’t know if it truly works but it does have the added benefit of smelling amazing. Also it seems to help clear my lungs. I have asthma and eucalyptus is very helpful to me.

  • My mother used to put a few drops on a bandana and tie it around my neck when I was a youngster for colds. I’m nearly 80 years old now. Guess the old is new again or we are recycling old remedies.

  • From what I’ve read online eucalyptus oil should NEVER be applied directly to the skin as it can cause irritation. Mix with a carrier oil first. Is this true Jillee?

    • Everyone has different skin, and if yours is particularly sensitive, then it’s best to use a carrier oil with all essential oils. The gentle swipe of a cotton ball suggested in today’s post is meant to be a strong application, but with as gentle of an application as possible. You get much less oil on your skin using the cotton ball than you would have if you had just dropped the oil straight onto your skin.

  • I can’t use air freshener sprays because of asthma. Two to three drops of eucalyptus or lemongrass oil in the potty before pooing & unless it’s really, really bad, no one will know you just went. We have a family member that won’t use the oil, so I just slip in that bathroom & add a couple of drops after they exit the room & it’s ready for the next time they go. lol

  • I suppose the tip regarding rats is for people who don’t have cats :). I might also recommend not killing the snakes in your yard, at least not until finding out for sure what species they are as most are non-venomous.

    Interesting tips, otherwise! I haven’t taken the EO plunge yet but I’m a huge fan of natural remedies and cleaners, so articles like this nudge me closer to the edge…

    • Please advise how to get rid of Garter Snakes… by the hundreds in one yard! My friend mows her grass and counted 12 she ran over in one mowing!!!! They’re around her house, in her shed, etc. She’s desperate to get rid of them because they’re so creepy!!!! Help!!

      • Maybe someone in your area would like to come and get them for their organic garden. They are excellent partners in the fight against insects.

      • I might ask what they’re hanging around for…if there’s an abundant food source nearby? But garter snakes are really harmless so she shouldn’t be afraid of them. I understand though that some people just don’t like snakes. We have a black ratsnake living around an open shed that we have named Our Lady of the Carport…

      • Join the discussion…Oh, Judy I feel SO very bad for your friend! I once lived in a little house and I could look out my back door on any given day and count dozens of them, all different sizes sunning themselves. I also BOUGHT a house with my fiancé right before the spring thaw, so we had no idea but there were dozens upon dozens there as well! I carried a how with me to the car…mailbox…wherever!! I absolutely hate them. Can’t really put my finger on it, but I just do. Yuck! I so wish I could help with some answers or even suggestions. God bless ALL of you dealing with this problem. Try talking to someone at an Ace Hardware store or Lowe’s…they might be able to help.

      • Hi Judy,tell your friend to get some snake mace,snake begone. She can call these phone numbers (901-870-7828 & 818-785-9321.She can also Google – how to get rid if snakes in yard. And don’t forget the power of prayer. May God be with her.

  • I wish had known sooner about some of these uses. I just spent money buying an
    an allergy medicine with a decongestant and also sinex severe formula. It would have saved me a lot of money.
