Best Natural Hayfever Remedies in Australia: What Actually Works?
At a Glance
Saline nasal irrigation is the only natural remedy with strong enough evidence to be recommended by doctors. Quercetin shows promise but needs more research. Most popular remedies — honey, essential oils, apple cider vinegar — have little to no clinical evidence for hayfever. If your symptoms are moderate or severe, natural remedies alone are unlikely to be enough.

Natural Hayfever Remedies: What Is Actually Worth Trying?
Hayfever affects a lot of Australians, so it is no surprise that plenty of people look for a non-drug option first. Sometimes that is because symptoms are mild. Sometimes it is because they are tired of taking tablets every spring. Either way, the market is full of products that promise natural relief without making it easy to tell what has evidence behind it and what does not.
Some natural approaches are genuinely useful, especially saline irrigation. Others are harmless but oversold. A few are mostly marketing. This guide separates those groups so you can set realistic expectations and avoid spending money on remedies that sound better on the label than they perform in real life.
How We Rated Each Remedy
To keep this practical, we have grouped the remedies by the strength of the evidence behind them:
- •GREEN — Reasonable evidence from clinical trials. Recommended or recognised by medical guidelines. Worth trying.
- •AMBER — Some promising evidence but not yet conclusive. May help some people. Proceed with realistic expectations.
- •RED — Little to no quality evidence, or evidence actively shows it does not work. Not recommended for hayfever.
We looked at systematic reviews, randomised controlled trials, and guidance from bodies like the Australasian Society of Clinical Immunology and Allergy (ASCIA) and the TGA. Where evidence is thin, we say so.
GREEN: Saline Nasal Irrigation — The Standout Performer
If you try only one natural remedy for hayfever, make it this one. Saline nasal irrigation involves flushing your nasal passages with a salt water solution using a squeeze bottle, neti pot, or pressurised spray. It physically washes out pollen, mucus, and inflammatory mediators from the nasal lining.
Evidence Rating: GREEN
Multiple systematic reviews — including a 2018 Cochrane review — support saline irrigation for allergic rhinitis. It is recommended as an adjunct treatment by ASCIA (Australasian Society of Clinical Immunology and Allergy) and most international allergy guidelines.
A 2018 Cochrane review found that saline irrigation improves symptom severity, reduces the need for medication, and improves quality of life in people with allergic rhinitis. Large-volume rinses (using a squeeze bottle) appear more effective than simple saline sprays, though sprays are easier and still beneficial.
Best Products for Saline Nasal Irrigation
There are three main options available at Australian pharmacies:
- •Large-volume squeeze bottle kits (NeilMed Sinus Rinse, Fess Sinu-Cleanse) — most effective. Flush 120-240ml of saline through each nostril. Best for moderate-to-severe congestion.
- •Saline nasal sprays (Fess Original, Fess Sensitive Noses) — easier to use, good for daily maintenance and mild symptoms. Less thorough than a full rinse but convenient.
- •Neti pots — gravity-fed ceramic or plastic pots. Effective but less convenient than squeeze bottles. Available from health food stores and online.
NeilMed Sinus Rinse Kit
Isotonic saline nasal irrigation system for drug-free relief of nasal congestion, allergies, and sinus symptoms. Includes squeeze bottle and premixed sachets.
Pros
- Strongest evidence base of any natural remedy
- Drug-free — suitable for pregnancy and long-term daily use
- Large-volume rinse for thorough pollen removal
- Premixed sachets make preparation simple
- Available at all major Australian pharmacies
Cons
- Takes practice to get the technique right
- Can feel uncomfortable at first
- Not convenient for on-the-go use
- Must use sterile, distilled, or previously boiled water — never tap water
Fess Sinu-Cleanse Gentle Cleansing Wash
Isotonic saline nasal irrigation kit with squeeze bottle. Drug-free relief for nasal congestion and sinus symptoms. Australian brand.
Fess Saline Nasal Spray
Non-medicated saline nasal spray to help relieve nasal and sinus congestion. Drug-free and suitable for daily use.
Safety Warning: Always Use Safe Water
Never use untreated tap water for nasal irrigation. Use distilled water, sterile saline from sachets, or water that has been boiled and cooled. In rare cases, contaminated tap water has caused serious infections. Always follow the manufacturer's instructions for cleaning your device.
AMBER: Quercetin — Promising But Needs More Research
Quercetin is a naturally occurring flavonoid found in onions, apples, berries, broccoli, and green tea. It has been shown in laboratory studies to stabilise mast cells — the immune cells that release histamine during an allergic reaction. In theory, quercetin acts as a natural antihistamine.
Evidence Rating: AMBER
Lab and animal studies are promising. A small number of human clinical trials suggest some benefit for allergic rhinitis symptoms, but they are generally small, short-term, and not all are well-designed. More high-quality human trials are needed.
A 2020 systematic review in Molecules found that quercetin demonstrates anti-allergic properties in vitro and in animal models, including inhibiting histamine release and reducing inflammatory cytokines. However, the leap from lab to real-world benefit is not straightforward. Human studies on quercetin for allergic rhinitis are limited, though a 2013 Japanese randomised controlled trial found that quercetin supplementation significantly reduced eye symptoms in pollen allergy sufferers.
In Australia, quercetin supplements are available over the counter as complementary medicines (AUST L listed with the TGA). They are not approved to claim they treat allergic rhinitis — their listed indications are typically limited to antioxidant activity. Typical supplement doses range from 500-1000mg per day.
Quercetin Supplements Available in Australia
Blackmores Quercetin Complex
Contains quercetin and vitamin C. Quercetin is a plant flavonoid with antioxidant properties found in onions, apples, and berries.
Herbs of Gold Quercetin Complex
Practitioner-strength quercetin complex with bromelain and vitamin C. Australian brand available in health food stores and pharmacies.
Swisse Ultiboost High Strength Quercetin
High-strength quercetin supplement. Quercetin is a naturally occurring flavonoid with antioxidant properties.
Pros
- Plausible mechanism of action (mast cell stabilisation)
- Generally well tolerated with few side effects
- Available over the counter at pharmacies and health food stores
- Some human trial data supporting symptom reduction
Cons
- Human clinical evidence is still limited and inconsistent
- Not recommended in medical allergy guidelines
- Poor oral bioavailability — you may not absorb much
- Relatively expensive compared to proven OTC antihistamines
- May interact with some medications including antibiotics and blood thinners
AMBER: Butterbur (Petasites) — Effective But Safety Concerns
Butterbur (Petasites hybridus) is one of the more interesting natural hayfever remedies because it actually has some decent clinical trial data. A 2007 systematic review in the journal Annals of Allergy found that butterbur extract was comparable to cetirizine (Zyrtec) for reducing hayfever symptoms in several randomised controlled trials.
Evidence Rating: AMBER — with Important Safety Caveats
Clinical trial evidence for efficacy is moderate — some trials show benefit comparable to antihistamines. However, raw butterbur contains pyrrolizidine alkaloids (PAs) that are toxic to the liver. Only PA-free standardised extracts (such as the European brand Petadolex) should ever be used, and these are difficult to find in Australia.
Here is the problem: butterbur in its raw form contains pyrrolizidine alkaloids (PAs), which are hepatotoxic — meaning they can damage the liver. The clinical trials used a specially processed PA-free extract called Petadolex (Ze 339), which removed these toxic compounds. This product is not widely available in Australia and the TGA has raised concerns about PA-containing herbal products.
If you cannot verify that a butterbur product is certified PA-free, do not take it. The potential liver toxicity is not worth the gamble, especially when safe and effective OTC antihistamines are readily available. We have not recommended a specific butterbur product here because of the difficulty sourcing verified PA-free formulations in Australia.
AMBER (Barely): Local Honey — Popular But Evidence is Thin
The theory behind local honey for hayfever is appealing: bees collect pollen from local plants, traces of this pollen end up in the honey, and eating it gradually desensitises your immune system — like a natural form of immunotherapy. It is easily the most popular folk remedy for hayfever in Australia.
Evidence Rating: AMBER (borderline RED)
The immunotherapy theory is plausible but largely unsupported by clinical evidence. The few studies that exist are small, and most have found no significant benefit over placebo. One 2013 Malaysian study showed some symptom improvement, but it had significant limitations.
There are several problems with the honey theory. Most hayfever in Australia is triggered by wind-pollinated grasses (especially ryegrass), not the insect-pollinated flowers that bees visit. The amount of allergenic pollen in honey is tiny and inconsistent. Real allergen immunotherapy uses precisely measured, standardised doses of specific allergens — honey provides neither consistency nor the right allergens.
A well-designed 2002 study published in the Annals of Allergy, Asthma & Immunology found no difference between local honey, commercially processed honey, and a honey-flavoured placebo for hayfever symptoms. A 2013 Malaysian study did show some benefit, but it used high doses (1g/kg body weight daily) and had a small sample size.
Our verdict: eating local honey is unlikely to harm you (unless you have a bee allergy or are giving it to a child under 12 months — risk of botulism). It is a tasty addition to your diet, but do not rely on it as a hayfever treatment. If it seems to help you, that may be placebo effect — which is still real relief, but not a reason to skip proven treatments when symptoms are significant.
GREEN: Lifestyle and Pollen Avoidance Strategies
These are not supplements or products — they are practical strategies that reduce your exposure to allergens. They are recommended by ASCIA and allergists as a foundation for managing hayfever, and they are free.
Evidence Rating: GREEN
Allergen avoidance is a cornerstone of allergy management recommended by all major guidelines. While you cannot eliminate pollen exposure entirely, reducing it meaningfully reduces symptom burden.
- •Check pollen forecasts daily — Melbourne Pollen Count (melbournepollen.com.au) and AusPollen provide daily forecasts during season. Stay indoors during high pollen counts when possible.
- •Keep windows and doors closed during high pollen periods, especially on windy days and during thunderstorms.
- •Dry clothes indoors or in a dryer during pollen season — clothes on the line collect pollen that you then wear against your skin and breathe in all day.
- •Shower and wash your hair after spending time outdoors to remove pollen from your skin and hair before it ends up on your pillow.
- •Wear wraparound sunglasses outdoors to reduce pollen contact with your eyes.
- •Use a HEPA air purifier in your bedroom — look for units with a true HEPA filter (captures 99.97% of particles 0.3 microns and larger). Run it overnight with the door closed.
- •Avoid mowing the lawn or gardening during high pollen periods, or wear a P2/N95 mask when you do.
- •If you have a car, use the recirculate setting on your air conditioning during pollen season rather than drawing in outside air.
RED: Remedies With Little to No Evidence
Vitamin C Mega-Doses for Allergies
Vitamin C has mild antihistamine properties in laboratory settings, and some people take high-dose vitamin C supplements for hayfever. However, there is no convincing clinical evidence that vitamin C supplementation meaningfully reduces hayfever symptoms. A 2018 review found that while vitamin C may have some theoretical benefit through reducing histamine levels, clinical studies have not demonstrated a reliable effect on allergic rhinitis. The Cochrane evidence for vitamin C and colds is also modest at best (see our vitamin C for colds guide). Do not expect it to replace an antihistamine.
Essential Oils (Eucalyptus, Peppermint, Lavender)
Eucalyptus and peppermint oils may provide a temporary sensation of clearer breathing due to menthol-like effects on nasal receptors. However, they do not reduce allergic inflammation, block histamine, or address the underlying immune response. There are no quality clinical trials showing essential oils are effective for hayfever. Some people find them soothing, which is fine, but do not use them as a substitute for evidence-based treatment. Be aware that essential oils can trigger respiratory irritation or allergic reactions in sensitive individuals, and should never be applied undiluted to skin or ingested.
Homeopathy
Multiple systematic reviews and meta-analyses — including a comprehensive 2017 review by the National Health and Medical Research Council (NHMRC), Australia's peak medical research body — have concluded that homeopathy is not effective for any health condition, including allergic rhinitis. The NHMRC found no good-quality evidence that homeopathy works better than placebo. Products such as homeopathic hayfever tablets (often sold in pharmacies) contain ingredients diluted to the point where no active molecules remain. We cannot recommend spending money on these products.
Apple Cider Vinegar
Apple cider vinegar (ACV) is frequently recommended online for hayfever, usually as a daily drink diluted in water. There is zero clinical evidence that ACV has any effect on allergic rhinitis. The proposed mechanisms (alkalising the body, breaking up mucus) are not supported by human physiology. Your body tightly regulates its pH regardless of what you drink. ACV will not reduce nasal inflammation, histamine release, or pollen sensitivity. Save your money.
Natural Hayfever Remedies: Evidence Comparison
| Remedy | Rating | Evidence Quality | Likely to Help? | Safety |
|---|---|---|---|---|
| Saline nasal irrigation | GREEN | Strong (Cochrane review, multiple RCTs) | Yes — proven to reduce symptoms | Very safe when using sterile water |
| Pollen avoidance / lifestyle changes | GREEN | Strong (guideline-recommended) | Yes — reduces allergen exposure | No safety concerns |
| Quercetin supplements | AMBER | Emerging (lab data strong, human trials limited) | Possibly — for mild symptoms | Generally safe; check for drug interactions |
| Butterbur (PA-free extract) | AMBER | Moderate (several RCTs) | Possibly — but hard to source safely in Australia | Only PA-free extracts; liver toxicity risk otherwise |
| Local honey | AMBER/RED | Weak (mostly negative trials) | Unlikely to provide meaningful relief | Safe for adults; not for infants under 12 months |
| Vitamin C (high-dose) | RED | Weak (no convincing hayfever trials) | No meaningful effect expected | Safe in moderate doses; GI upset at high doses |
| Essential oils | RED | Very weak (no quality trials) | May feel soothing but does not treat allergy | Can cause irritation; never ingest |
| Homeopathy | RED | None (NHMRC: not effective for any condition) | No | Safe but a waste of money |
| Apple cider vinegar | RED | None (no clinical trials) | No | May erode tooth enamel with regular use |
When Natural Remedies Are Not Enough: The Treatment Ladder
Let us be direct: if your hayfever is moderate to severe — meaning it disrupts your sleep, affects your concentration at work or school, or makes you miserable for weeks — natural remedies alone are unlikely to control your symptoms adequately. This is not a failure. Hayfever is an immune system overreaction, and sometimes you need medication that directly targets the immune response.
Think of hayfever management as a ladder. You can start with natural approaches and step up as needed:
- •Step 1 — Pollen avoidance strategies and saline nasal irrigation. Free, safe, and a good foundation for everyone.
- •Step 2 — Add a non-drowsy OTC antihistamine (cetirizine, loratadine, or fexofenadine). These are cheap, effective, and well-tolerated. See our best antihistamine guide for comparisons.
- •Step 3 — Add a corticosteroid nasal spray (Nasonex, Flixonase, Rhinocort, Beconase). These are the gold standard for moderate-to-severe nasal symptoms and are available without prescription in Australia.
- •Step 4 — Combination therapy: antihistamine tablet + corticosteroid nasal spray + antihistamine eye drops (Zaditen, Patanol) if eyes are affected.
- •Step 5 — See your GP. If the above is not enough, your doctor may consider prescription options, referral to an allergist, or allergen immunotherapy (desensitisation).
Natural + OTC = A Sensible Combination
You do not have to choose between natural and conventional. Many allergists recommend saline irrigation alongside antihistamines and nasal sprays. The saline rinse clears pollen and mucus, allowing the medicated spray to reach the nasal lining more effectively. They work better together than either alone.

Frequently Asked Questions
Does local honey really help hayfever?
Probably not in any meaningful way. The theory is appealing — local bees collect local pollen, you eat the honey, your body builds tolerance. But most hayfever is triggered by wind-pollinated grass pollen (especially ryegrass), not the insect-pollinated flower pollen that bees collect. Clinical studies have mostly found no difference between local honey and placebo. It will not harm you, but do not rely on it as your primary treatment.
Is quercetin a good natural antihistamine?
In laboratory tests, quercetin does stabilise mast cells and reduce histamine release. However, translating lab results to real-world symptom relief is a big leap. A few small human studies show some promise, particularly for eye symptoms. If you want to try quercetin, go in with realistic expectations — it is unlikely to be as effective as cetirizine or fexofenadine. It is generally safe, but check with your pharmacist if you take other medications, particularly antibiotics or blood thinners.
Can I use saline nasal irrigation every day?
Yes. Daily saline irrigation is safe for long-term use during hayfever season. Some ENT specialists recommend it as a daily nasal hygiene routine, much like brushing your teeth. Always use sterile, distilled, or previously boiled water — never straight from the tap. Clean and dry your irrigation device between uses according to the manufacturer's instructions.
Are natural hayfever remedies safe during pregnancy?
Saline nasal irrigation is considered safe during pregnancy and is often recommended as a first-line option because it is drug-free. However, herbal supplements including butterbur and high-dose quercetin have not been adequately studied in pregnancy and should be avoided unless specifically approved by your obstetrician or midwife. Always consult your GP or pharmacist before using any remedy during pregnancy or breastfeeding.
Why does the NHMRC say homeopathy does not work?
In 2015, Australia's National Health and Medical Research Council completed the most comprehensive review of homeopathy evidence ever conducted. After assessing over 1,800 studies, they concluded there was no reliable evidence that homeopathy is effective for any health condition. The fundamental principle of homeopathy — that substances become more potent as they are diluted — contradicts established physics and chemistry. The NHMRC concluded that people who choose homeopathy may put their health at risk if they reject or delay treatments that have been shown to be effective.
Can I combine natural remedies with antihistamines or nasal sprays?
Absolutely — and this is what most allergists recommend. Saline irrigation works well alongside medicated nasal sprays: do the saline rinse first to clear mucus and pollen, then use your corticosteroid spray so it reaches the nasal lining effectively. Lifestyle strategies like pollen avoidance and HEPA filters complement any medication regimen. If you are taking quercetin or other supplements, let your pharmacist know so they can check for interactions with your other medications.
The Honest Verdict
Our Recommendation
Saline nasal irrigation is the clear winner among natural hayfever remedies — it has solid clinical evidence, is safe, affordable, and recommended by doctors. Pollen avoidance strategies are sensible and free. Quercetin is an interesting prospect but still unproven in robust human trials. Everything else — honey, essential oils, homeopathy, apple cider vinegar — lacks meaningful evidence for hayfever, no matter what the wellness blogs claim. If your symptoms are more than mild, be pragmatic: use saline irrigation as your natural foundation, and add affordable OTC antihistamines or corticosteroid nasal sprays as needed. There is no shame in using medication that works.
