Essential Oils for Sore Throat: Natural Relief Remedies

Updated October 2026 · Reviewed for safety and accuracy by the Lively Living team

That raw, scratchy feeling in your throat can make swallowing feel like sandpaper. Most sore throats come with a cold and clear up on their own within a week, and in the meantime, many people like to add a few drops of essential oil to their comfort routine. This guide covers what usually causes a sore throat, the oils people most often reach for, how to use them safely, and when it's time to see your GP.

What causes a sore throat?

Most sore throats are caused by viruses, such as the ones behind the common cold and flu. Less often, bacteria are the cause, as with strep throat. Dry air, smoke, hay fever and straining your voice can also leave your throat feeling raw.

Viral sore throats usually get better on their own in 3 to 7 days, and antibiotics don't help them. Bacterial infections may need antibiotics, which is why it's worth seeing your GP if your sore throat is severe or isn't improving. healthdirect has more on sore throats and their causes.

Simple comfort measures that matter most

Before we get to essential oils, these everyday steps make the biggest difference while your body does its work:

Step 1. Rest, and give your voice a break.

Step 2. Drink plenty of fluids. Warm drinks such as herbal tea with honey are soothing (no honey for babies under 12 months).

Step 3. Gargle with warm salt water: half a teaspoon of salt in a glass of warm water (for adults and older children who can gargle without swallowing).

Step 4. Suck on a throat lozenge or ice block (not for young children, who can choke).

Step 5. Keep the air moist. Dry air can make a scratchy throat feel worse, especially overnight. A cool mist humidifier or ultrasonic diffuser by the bed keeps the room comfortable.

Your pharmacist can also suggest over-the-counter options to ease the pain.

Essential oils people use for a sore throat

Essential oils aren't a treatment for a sore throat and won't cure an infection. What they can do is add a comforting, familiar scent to your rest-and-recover routine, and some, like eucalyptus and peppermint, give that fresh, clear feeling many people enjoy when they're feeling stuffy. Here are the oils most often used.

Eucalyptus

The classic scent of winter. Eucalyptus is rich in 1,8-cineole (eucalyptol), which gives it its fresh, clearing aroma. There are hundreds of species of eucalyptus, and we chose Eucalyptus radiata for its gentler nature and softer, sweeter scent. Diffuse it, or add a drop or two to a bowl of steaming water. Learn more in our guide to eucalyptus oil.

Peppermint

Peppermint contains menthol, the ingredient behind the cooling feeling of many throat lozenges. Diffused or breathed in from a tissue, it gives a cool, fresh sensation. Peppermint is for adults only: keep it away from babies and children under 6.

Tea tree

An Australian favourite, tea tree has a fresh, medicinal scent that many people like to diffuse around the home when someone is unwell.

Lavender

When you're feeling run down, rest is everything. Soft, floral lavender is the classic bedtime oil and a lovely partner for eucalyptus in an evening blend.

Lemon

Bright and uplifting, lemon freshens the air in a sick room. Cold-pressed citrus oils can make skin more sensitive to the sun, so keep lemon to the diffuser.

Thyme, oregano and clove

You'll see these strong "hot" oils mentioned online. They can irritate skin and the airways, so they're best left out of a sore throat routine, and never used around children.

Ready-made blends

If you'd rather not mix your own, our certified organic Winter Rescue blend is a family favourite for diffusing in the cooler months, and our Breathe blend, with Eucalyptus globulus, is a fresh option for adults.

Winter Rescue Family Size (30ml)

A simple diffuser blend

Clear and calm diffuser blend (adults, for diffusing only):

3 drops Eucalyptus radiata
2 drops lavender
1 drop lemon

Add to your diffuser with water and run it for 30 to 60 minutes in a well-ventilated room. If there are children in the house, leave out the peppermint and keep the session short.

How to use essential oils safely

Diffusing. Follow your diffuser's instructions, usually 3 to 6 drops. Diffuse in a ventilated room, take breaks, and keep the diffuser out of reach of children and pets.

Steam. Add 1 to 2 drops to a bowl of hot (not boiling) water, close your eyes and breathe the steam for a few minutes. Take care, as hot water can scald, and don't use steam bowls with children.

A tissue. Put a drop on a tissue and breathe in gently. Keep it away from your eyes.

On the skin. Never apply essential oils undiluted. For adults, mix 1 to 2 drops with a teaspoon (5ml) of carrier oil, patch test first, and apply to the upper chest or back of the neck. Our carrier oil guide explains how.

Relaxing bath soak with essential oils

Never swallow essential oils, and never add them to drinks or gargles. Some oils, including eucalyptus, can be very harmful if swallowed, even in small amounts. If an oil is swallowed, call the Poisons Information Centre on 13 11 26.

Pregnancy and breastfeeding. Check with your GP or midwife before using essential oils.

Children. Children are more sensitive to essential oils. Avoid peppermint and stronger eucalyptus oils around young children, and use only gentle oils or blends made for kids. Our guide to essential oils for kids covers what's suitable by age. For more, see our essential oil safety guide.

When to see a doctor

See your GP if your sore throat:

is severe, or hasn't improved after a few days
comes with a high fever, swollen glands or a rash
makes it hard to swallow fluids
keeps coming back

Call 000 if you have trouble breathing, can't swallow your own saliva, or are drooling. If you're unsure, call healthdirect on 1800 022 222 to speak with a registered nurse any time.

Frequently asked questions

What is the best essential oil for a sore throat?

Eucalyptus, peppermint (adults only), tea tree and lavender are the oils people use most often. They won't treat a sore throat, but many people find their scents comforting while they rest.

How do you soothe a sore throat quickly?

Warm drinks with honey, salt water gargles, lozenges, plenty of rest and moist air are the simplest options. Your pharmacist can recommend pain relief if you need it.

How do I use eucalyptus oil for a sore throat?

Diffuse a few drops in a ventilated room, or add 1 to 2 drops to a bowl of hot water and breathe the steam with your eyes closed. Never swallow eucalyptus oil.

Can essential oils prevent strep throat?

No. Strep throat is a bacterial infection that needs to be diagnosed and treated by a doctor. Essential oils can't prevent or treat it.

The bottom line

A sore throat usually passes in a few days with rest, fluids and a little extra care. Essential oils like eucalyptus and lavender can make your recovery space feel calmer and fresher, as long as you use them safely, and your GP is there if things don't improve.
