Essential Oils to Reduce Fever Naturally (Ways of Action and How to Use Them)


A fever is an abnormally raised body temperature. It is usually caused by pathogens that cause infection in the body. But it can also occur when there are toxins present and the body tries to get rid of them.


A fever is the only way your body can get rid of what’s causing it. High temperatures kill bacteria and/or viruses and prevent their growth. A fever is also the best way to build up a stronger immune system. I’ll tell you more about the causes, signs and other facts about fever later on.


How can essential oils help with fever?

Essential oils are very concentrated plant extracts, otherwise known as second metabolites. These metabolites are active molecules with different health effects and benefits.


To a plant, they serve as protection (from sun, predators, injuries, etc.). These molecules are highly aromatic also, which helps with pollination. Pollination ensures the survival of the species. The chemical composition of an aromatic oil is influenced by:


  • Geographical area.
  • Altitude.
  • Harvest time and method.
  • Processing and distillation.
  • Storage conditions.


There are over a hundred different types of aroma essences. Some of them are better at killing bacteria and viruses than others.


Others are better at stimulating collagen production and preventing premature aging. Some are just great repellents and work as anti-anxiety and depression substances. The list can go on and on.


Here are the most important properties and effects of a good essential oil for fever:


  • Antibacterial. To help the body destroy and get rid of the pathogen that’s causing fever faster.
  • Antiseptic. Protects from new infections.
  • Anti-inflammatory. Decreases the level of inflammation inside the body and help reduce the fever.
  • Analgesic. To relieve the pain felt throughout the body from high temperature (muscles especially).
  • Immunomodulator. Helps strengthen the immune system to better fight bacteria and viruses.
  • Diaphoretic. Induces sweating to cool off the body and regulate temperature. Sweat can also help remove certain toxins from the body. This is usually done by stimulating circulation, which increases warmth.
  • Respiratory. This is an effect due to antibacterial properties and blood flow stimulation. Essential oils that can reduce fever can also improve breathing.
  • Promote sleep. Rest is crucial while battling viral infections or any kind of internal inflammation. Many essential oils can induce relaxation, slow down the heart rhythm and help you sleep.


Essential oils to reduce fever (antipyretics) should be used only when it is too high (above 38 C/100.4 F). You want it to run its course, to get rid of the cause.


You should not worry about a fever if it’s below 102.2 F unless serious discomfort kicks in. Very high temperatures can lead to delirium, among others.


The chemical profile of an essence is unique and very complex. All these active molecules are very small.  They can penetrate the blood-brain barrier and reach the nervous system fast.


They are small enough to absorb into the skin and reach the blood through it. They will then travel to the injured area through blood and strengthen the immune system. That is also how they help destroy the germs and pathogens.


Natural Remedies for Fever, Chills and Flu


How to Use Essential Oils for Fever and Chills (and Colds)

Being so concentrated, essential oils should never be applied undiluted to the skin! Otherwise, they can burn, sensitize or irritate the skin. It’s best to mix them with anti-inflammatory carrier oils first. Mix 6 – 18 drops of essential oils for fever and chills in an Oz (30ml) carrier.


Some of the best carrier oils for fever and inflammation are:


  • Black seed (Nigella sativa).
  • Tamanu (Calophyllum inophyllum).
  • Olive.
  • Hemp seed.
  • Etc.


For example, Nigella oil can also give the immune system a boost and act as an antibacterial also.


Besides topical application, you can also diffuse essential oils. What essential oils to diffuse for fever? Any oil with antibacterial and antiviral properties is great for diffusion.


Diffusion can kill airborne pathogens and prevent infections like the flu or colds. They can also strengthen the immune system, relieve breathing passages, soothe aching muscles, help you sleep, etc.


The best essential oils to diffuse for fever are:


  • Eucalyptus.
  • Peppermint.
  • Thyme.
  • Orange.
  • Lemon.
  • Wintergreen.
  • Birch.
  • Frankincense.
  • Ravintsara.
  • Green Myrtle.
  • Manuka.
  • Etc.


The amount of oil drops used per diffusion depends on the area in which it’ll take place. If it’s a very large room with good ventilation, you could diffuse up to 20 drops, every 2 hours. If the room is small, obviously, the amount of essential oils used will be smaller (5 – 7 drops).


Avoid diffusing Aromatherapy oils continuously! Studies show that inhaling for 60+ minutes can stress the body, elevate heart rate, cause insomnia, etc.


A proper diffusion should last 20 – 30 minutes at the most. Once you stop the device, the oils will continue diffusing.


You can learn more about how to use a diffuser and which one to pick here.


Essential oils for fever in adults and children alike can be added to hot baths too. Mix 10 drops of an antibacterial oil with a cup of salt (Epsom, Himalayan, sea, etc.) and add it to a hot, steaming bath.


The steam will diffuse the oil molecules and improve your breathing and mood. That’ll soon lead to a better-regulated body temperature.


NO essential oil should be taken internally without the advice of a doctor! They can cause serious side effects. Especially if the dose is not right or if there are other health conditions present.


Peppermint Oil for Fever Relief! Why and How to Use It


Peppermint is one of the oldest remedies for many different ailments. From a bad digestion and repelling insects to growing hair and improving breathing, the list is long.


Studies show that Peppermint essential oil is a great antipyretic. This means the oil contains all the right molecules to reduce high body temperature (fever). Let’s see exactly why Peppermint oil for fever is so popular and useful, especially for fever and chills.


Peppermint Essential Oil for Fever

Botanical name: Mentha piperita.

Peppermint Oil for Fever Relief


  • A pure and good quality Peppermint oil can contain between 30% and 55% menthol. Menthol is a substance that induces a cooling sensation right after application. Thus, the substance stimulates the cold receptors of the skin by inhibiting calcium channels.
  • Peppermint oil is a calcium channel blocker. This property makes it a great analgesic (pain reliever) by increasing the pain threshold. At least that’s what this study on mice showed. This means that applied locally, Peppermint oil for fever can also soothe muscle aches.
  • The oil can also ease the discomfort felt during fever, like nausea, vomiting, cramps, etc.
  • Peppermint has strong antibacterial and antiviral properties too.
  • The oil can also soothe inflammation and improve breathing.



  • If used on large surfaces, Peppermint oil can induce hypothermia. This is a serious shock for the body, as the substance can decrease the body temperature faster than it can produce heat. That happens when the temperature of the body drops under 35 C (95 F).
  • Peppermint oil has hormone-like effects, which means it can stimulate menstruation. Depending on case, this could be a wanted or unwanted side effect.
  • Peppermint should not be used easily and certainly, not on long periods of time.
  • The oil can induce seizures so its use is not for epileptic people.
  • In high amounts, this essential oil can be toxic to the liver and kidneys. It can also cause jaundice to all those who lack the G6PD enzyme.
  • People with serious heart conditions should also use it carefully.
  • Avoid using more than 10 – 15% of Peppermint in diffusion. It’s best to mix it with a citrus oil for diffusion.
  • Peppermint oil should not be used on babies, children, pregnant or breastfeeding women.


Why I like it:

I like Peppermint oil for fever because it doesn’t take much to feel better. As long as you use it in small amounts, it can relieve much of the discomfort caused by fever. It can improve digestion, skin conditions and it smells very fresh and uplifting. Peppermint oil is also great for chills too.

How to dilute Peppermint oil for fever?

Diluting Peppermint oil for fever is the same as with any other essential oil. Mix Peppermint oil with Nigella oil (Olive, Hemp, etc.) for topical application, or salt for bathwater.


The amount of drops used for topical use depends on the area where it’ll be applied. If you’re looking to improve breathing, use 1 – 3 drops per teaspoon carrier.  Rub the blend on the forehead, avoiding the eye area at all costs. It can make them watery.


If the blend will be used on the body, you can mix up to 20 drops per Oz (30ml) carrier oil.


A Peppermint oil blend for fever and chills can be applied on:


  • Chest.
  • Along the spine.
  • Arms.
  • Soles of the feet.
  • Back of the neck.


You can also pour a drop or two on a warm compress (or towel) and keep it on the forehead or the back of your neck. You can repeat the process, without adding more Peppermint.

Peppermint Oil Recipes to Reduce Fever

This oil won’t break down the fever, but it will help keep it in check. This means that it may either reduce it by a degree or two or simply prevent it from rising too high. Try these blends on yourself or somebody with fever:


Natural Fever Reducer (Peppermint Recipe)

You’ll need:

  • Peppermint essential oil: 10 drops

Other Essential Oils for Fever in Adults and Children


Luckily, there’s not just Peppermint oil good for fever. We have lots of other therapeutic essences that can help the body fight off germs and infections. Like I said, body temperature can be lowered naturally, without messing with the natural process of the immune system.


Many doctors agree that fever reducers are not as effective as one might think. Dropping the fever suddenly can lengthen the time of recovery and healing. This way, it takes more effort and time to eliminate the source of the fever.


I’ve picked two of the most important oils for fever and cold, to talk about their pros and cons. But I will talk about other essential oils and their effects too.


1) Wintergreen Essential Oil

Botanical name: Gaultheria fragrantissima/procumbens.

Essential Oils to Reduce Fever - Wintergreen oil


  • Wintergreen is considered an antipyretic oil because it’s very high in methyl salicylate (95 – 99%). This substance acts just like aspirin, being part of the same family.
  • Thus, the oil of Wintergreen for fever can relieve the pain felt in the muscles and joints.
  • This oil is highly anti-inflammatory, which helps the body get rid of the source faster.
  • Wintergreen essential oil can also dilate the blood vessels and regulate the circulation.



  • The oil of Wintergreen is recommended only for topical use.
  • In high doses, methyl salicylate was found very toxic. A teaspoon of methyl salicylate can even cause death in adult humans. Wintergreen needs to be properly diluted and used in very small amounts.
  • Seek medical counsel before using Wintergreen oil for fever if you suffer from epilepsy or asthma.


Why I like it:

Although Wintergreen is a medicinal oil, its smell is quite pleasant and sweet. The oil is also great at strengthening the immune system, rheumatism, arthritis and even skin problems.

2) Ravintsara Essential Oil

Botanical name: Cinnamomum camphora.

Essential Oils to Reduce Fever - Ravintsara oil


  • Ravintsara is the best oil for fever, colds and chills. It is especially good at strengthening the immune system by stimulating the adrenal glands.
  • The oil can also sooth all the discomfort caused by the fever. Ex.: Aching muscles, inflammation, infection, low energy, etc.
  • Ravintsara is a very efficient antiviral essential oil. It can be used for fever in both adults and children.
  • Diffused, it can also help relieve mucus and disinfect sinuses.
  • Ravintsara can be used to improve the quality of sleep. A good rest is needed for recovery during and after fever.



  • People with asthma, seizures and/or epilepsy must use Ravintsara oil for fever carefully. There’s a high risk of getting seizures with a high dose of Ravintsara.
  • It may interfere with certain medications. It’s best to use it occasionally and on a short term. Or to talk to a medical professional about possible interactions.
  • Prolonged use of Ravintsara oil may cause addiction!


Why I like it:

Ravintsara has a truly pleasant and interesting scent. It’s spicy, fresh and balsamic, with eucalyptus-like notes. It’s among the best essential oils to reduce fever and prevent flu or colds. It can also uplift the mood and give all the vital signs a boost.

Essential Oils to Reduce Fever (Natural Remedies)


Fever Facts, Tips and Practical Recipes to Reduce It


How long is too long to have a fever? When should you start worrying? What are the signs and symptoms? What other remedies and tips are there to reduce fever?


Find out the answers to these and more, plus practical recipes right now. They’ll help you reduce fever and chills next time your body has to deal with them.


Whenever there’s an infection or inflammation in the body, the immune system kicks in. It releases certain cells (e.g.: white blood cells or macrophages) that destroy foreign bodies. Macrophages get rid of pathogens by engulfing them. The next step is to digest them and then eliminate the residues from the body.


Macrophages release substances that increase the body temperature. High body temperature or fever contributes to the killing of the foreign bodies. High temperatures make hostile environments for bacteria and viruses.


However, if it’s too high, you should go to the doctor to have your fever checked. There are many causes for a fever, some of them can be life-threatening.


Most of them, however, are not dangerous to the overall health. The causes of fever can be one or more of the following:


  • Sunstroke.
  • Excess stress and fatigue.
  • Viral infection.
  • Bacterial infection.
  • Teething.
  • Tonsillitis.
  • Ear infections.
  • Chickenpox.
  • Urinary tract infection.
  • IBS.
  • Meningitis.


The symptoms of a fever:

  • Burning sensation.
  • Chills (alternating cold and hot sensations).
  • Headaches.
  • Vomiting.
  • Muscle and joint pain.
  • Muscle tenderness.
  • Difficulty in moving.
  • Febrile seizures in children.


Luckily, using essential oils to reduce fever will actually strengthen your body. That allows it to fight the cause on its own and create the necessary antibodies that will later prevent fever.


  • Upon waking up, the body temperature is 36.7 C – 37 C (98.6 F – 98.6 F).
  • In the evening, the body temperature slightly rises, from 37 C to 37.3 C (98.6 F – 99.14 F).
  • Anything higher, we call it a fever.


When should you worry about a fever? It’s important to let it run its course, but if it rises too much (above 38 C – 100.4 F), it’s best to seek medical help.


  • It’s especially important to rule out meningitis, which can be deadly.
  • Also, if you have fever for more than 3 days, you should go see the doctor.
  • A doctor should see your baby if he or she is under 3 months old and has 104 F temperature.
  • People and children with compromised immune systems also need a consultation.


Pharmaceutical fever reducers should only be taken in case you feel really bad. Not just for the sake of reducing the fever.


Tips to Relieve (or Bring Down) a Fever

  • Take hot baths to relieve breathing problems. Don’t forget to add in essential oils for fever.
  • Rub your soles, spine and chest with warming/cooling essential oils. They will either induce sweating to regulate body temperature or stimulate the cold receptors.
  • Diffuse antiviral essential oils to prevent infections and breathe in pure air. This will also prevent others from getting sick.
  • Sleep at least 8 hours, so the body can focus only on eliminating the source of fever.
  • Eat light foods (soups, broth and fruits or veggies). Digestion takes energy and effort from the body. Two things it needs to combat the infection or inflammation.
  • Drink plenty of water and teas to keep hydrated. Warm teas can also induce sweating and cause temperature regulation.
  • Wear loose and thin clothes, best from cotton, to absorb the sweat.
