Essential Oils for Hayfever: Your Guide to Allergy Relief

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

Spring in Australia is beautiful, until the pollen arrives. For many of us, it brings sneezing, itchy eyes and a nose that won't stop running. Hay fever is very common in Australia, and while essential oils can't treat allergies, many people enjoy using them as part of a comfortable spring routine. This guide covers what hay fever is, the oils people reach for most, how to use them safely, and the practical steps that make the biggest difference.

What is hay fever?

Hay fever, or allergic rhinitis, is an allergic reaction to things in the air such as grass and tree pollen, dust mites, mould spores and pet dander. It causes a runny or blocked nose, sneezing, itchy and watery eyes, and an itchy throat.

It's easy to mistake hay fever for a cold, but there are some clues. Colds often come with aches and a mild temperature and clear up within a week or two. Hay fever doesn't cause a fever, tends to come back at the same time each year, and lasts as long as you're exposed to the trigger.

If you have asthma as well as hay fever, talk to your GP about an asthma action plan, especially during grass pollen season, when thunderstorm asthma can occur in some parts of Australia.

Practical ways to reduce your exposure

Step 1. Check the pollen forecast and stay indoors on high pollen days and windy days if you can.

Step 2. Keep windows closed during peak pollen times, and set the car air conditioning to recirculate.

Step 3. Shower and change your clothes after time outdoors, and dry washing inside during pollen season.

Step 4. Wear wraparound sunglasses to keep pollen out of your eyes.

Step 5. Rinse your nose with saline to wash away pollen.

Step 6. Talk to your pharmacist or GP about hay fever medicines. There are several effective options, and they can help you choose what suits you.

Essential oils people use in hay fever season

Essential oils aren't an allergy treatment and won't replace your hay fever medicine. What they can do is make your home feel fresher and more comfortable, and some have that clean, clearing scent many people enjoy when they're stuffy.

Eucalyptus radiata. Fresh and clearing, eucalyptus is the classic scent for a stuffy head. Of the hundreds of eucalyptus species, we chose radiata for its gentler nature and softer, sweeter scent.

Peppermint. Cool and refreshing, thanks to its menthol. For adults only, and keep it away from your eyes.

Lavender. Hay fever can disturb sleep. Soft, floral lavender is a lovely oil for winding down in the evening.

Lemon. Bright and uplifting, a favourite for freshening the house in spring.

Tea tree. Fresh and herbaceous, often added to homemade cleaning sprays.

Seasonal Relief. Our certified organic blend, created for diffusing during the change of season.

How to use essential oils

Diffuse. Add 3 to 6 drops to an ultrasonic diffuser and run it for 30 to 60 minutes in a ventilated room. Try 3 drops Eucalyptus radiata, 2 drops lemon and 1 drop lavender. Keep the diffuser clean so mould doesn't build up in the tank.

Breathe from a tissue. Put a drop of eucalyptus on a tissue and breathe in gently when you're out and about. Keep it away from your eyes.

Chest balm. If you'd like a rub, dilute well: for adults, 1 to 2 drops of essential oil per teaspoon (5ml) of carrier oil or unscented balm, applied to the chest or back of the neck. Our carrier oil guide explains how to dilute safely.

Cleaning spray. Dust and pollen settle on surfaces. Mix equal parts water and white vinegar in a spray bottle with a few drops of tea tree or lemon, and wipe down benches and windowsills. Damp dusting and a vacuum with a HEPA filter pick up more allergens than a dry duster.

Safety first

Essential oils can trigger allergies too. If you have sensitive airways or asthma, strong scents can make symptoms worse. Start with a short diffuser session and stop if you notice any irritation, and check with your GP first if you have asthma.
Always dilute before putting oils on your skin, and patch test on your inner arm first.
Never swallow essential oils or put them in or near your eyes. If an oil is swallowed, call the Poisons Information Centre on 13 11 26.
Children are more sensitive. Keep peppermint and stronger eucalyptus oils away from babies and young children. See our guide to essential oils for kids for gentler options.
Pregnant or breastfeeding? Check with your GP or midwife first.
Keep oils out of reach of children and pets.
