Olive Oil for Ears: Using It to Soften Earwax, Safely
Using olive oil for ears is one of the few home remedies the NHS itself describes. If earwax has built up and your ear feels blocked, the NHS and Ireland's HSE both advise putting 2 to 3 drops of olive or almond oil in the ear, 3 to 4 times a day for 3 to 5 days, lying with the affected ear facing up for 5 to 10 minutes each time. The oil softens the wax so it can work its way out, usually over about two weeks. Neither page spells out how thin the research is, why a daily oiling habit can backfire, or exactly when oil should stay out of your ear. This guide covers all three, naming each study with its design and size.

The Short Answer
- The NHS method is simple: 2 to 3 drops of olive oil in the blocked ear, 3 to 4 times a day for 3 to 5 days, lying on your side for 5 to 10 minutes after each dose.
- Oil softens earwax rather than dissolving it; lumps of wax should come out on their own over roughly two weeks.
- The evidence is modest: a 2018 Cochrane review of 10 trials found no high-quality evidence that any ear drop beats another.
- More is not better. In a 2013 study of 50 people over 50, a nightly olive oil spray used for 24 weeks left more material in the treated ear, not less.
- Do not put oil in your ear if you have, or may have, a perforated eardrum, grommets, previous ear surgery, ear pain, discharge or a fever — see a pharmacist or GP instead.
- Never use cotton buds or fingers to dig wax out, and skip ear candles: the NHS says there is no evidence they remove earwax.
How to Use Olive Oil for Earwax: The NHS Method
The NHS page on earwax build-up (last reviewed January 2024) and the HSE page adapted from it (reviewed April 2026) give the same routine, step for step:
- Lie on your side with the affected ear facing up.
- Put 2 to 3 drops of olive oil into the ear. Almond oil is an alternative, but not if you are allergic to almonds or nuts.
- Stay lying on your side for 5 to 10 minutes so the oil can reach the wax.
- Repeat 3 to 4 times a day, for 3 to 5 days.
- Expect lumps of softened wax to come out of the ear by themselves over about two weeks.
- If symptoms have not cleared after 5 days, or the ear is so blocked you cannot hear, see a pharmacist or the nurse at your GP surgery.
Two practical points the official pages leave implicit: use a clean dropper, and keep a tissue handy when you sit up, because some oil will run back out. This is a short course for a blocked ear, not a daily ritual.
Does Olive Oil Actually Work? What the Evidence Shows
Earwax is not dirt. The HSE describes it as a natural, protective substance that traps dust and helps prevent infections, and it usually leaves the ear on its own. Oil helps only when that fails and wax becomes hard or packed.
The most rigorous summary is a 2018 Cochrane systematic review by Aaron, Cooper, Warner and Burton, which assessed 10 randomised trials with 623 participants (900 ears) testing drops and sprays for ear wax. A single study found that five days of drops led to complete clearance in 22% of ears, against 5% with no treatment — low-quality evidence from 117 ears. Across studies there was no evidence that oil-based drops beat water-based ones, or that any commercial drop beat plain water or saline. The authors concluded that no high-quality evidence allows a firm verdict.
An earlier NIHR Health Technology Assessment review of 26 trials (Clegg and colleagues, 2010) reported olive oil was more effective than no treatment, while stressing that good-quality evidence was limited.
The honest summary: softening drops probably help, olive oil is a reasonable and cheap choice, and nobody has shown it is better or worse than the alternatives.
The Catch: A Nightly Oil Habit Can Mean More Wax
The study most people have never heard of is the one that matters for anyone tempted to oil their ears every night "to keep them clear". In 2013, ear-care nurse specialist Rosemary Rodgers published an experimental study in Practice Nursing of 50 people over 50 with wax in both ears. After both ears were cleared, each person sprayed 0.05 ml of olive oil into one ear every night for 24 weeks, while the other ear served as the untreated comparison.
The nightly oil did not help wax leave the ear. At 24 weeks, the median weight of material removed from the treated ears was 99.5% greater than from the untreated ears, and video otoscopy showed more blockage. The same study found something useful, though: a spray of oil immediately before removal allowed all the wax to be taken out at the first attempt.
The study is small and was run by a single researcher, so it is not the last word. The NHS does say regular use of drops or oil can help soften build-up, so the sensible reading is to use oil when wax is causing symptoms, or before a removal appointment, rather than indefinitely out of habit. If you get repeated build-ups, ask a pharmacist or practice nurse what routine suits your ears.
That pre-removal use is now being tested properly. An NHS audiology service in North Wales has published the protocol for a cluster randomised trial across 26 GP practices, planned to include 1,742 adults, comparing olive oil drops with olive oil spray used for seven days before microsuction (Jones, Munro and Wild, Trials, 2025). Results are not yet published.
When Not to Put Olive Oil in Your Ear
Do not put oil in your ear — speak to a pharmacist or GP instead — if any of these apply:
- A perforated eardrum, or you think you may have one. Both the NHS and HSE say not to use drops if there is a hole in the eardrum.
- Grommets or previous ear surgery. The NHS describes grommets as small tubes implanted in the ear; an NHS trust's self-treatment leaflet tells anyone who has had ear surgery not to use oil drops.
- Ear pain, discharge, a high temperature or swelling around the ear. These are signs of an ear infection, not simple wax. The NHS says to get urgent advice from a GP or NHS 111 if fluid is coming out of the ear or hearing changes alongside infection symptoms.
- An allergy to the oil you plan to use, such as almond oil with a nut allergy.
A 2013 animal study by Emami and Daniel in The Laryngoscope found no hearing loss when olive oil was applied to perforated eardrums in 11 chinchillas. That is not reassurance for people: it was a small animal model, and its authors called for clinical studies. The human guidance says no.
The NHS also warns against fingers or objects such as cotton buds, which push wax further in, and says there is no evidence that ear candles or ear vacuums remove earwax. If wax will not shift, some GP practices or local NHS services offer irrigation or microsuction, which are usually painless.
Kitchen Olive Oil or Pharmacy Ear Drops?
Pharmacies sell olive oil ear drops and sprays; the NHS page simply says "olive or almond oil". No research above shows a pharmacy product softens wax better than plain kitchen olive oil. The differences are hygiene and convenience.
- A pharmacy dropper or spray is sealed and measures a dose easily.
- With kitchen oil, pour a little into a clean dish and use a clean dropper, rather than dipping into the main bottle.
- Unfiltered olive oils, ours included, can show natural sediment, which is harmless in food. For ears, pour from the clear top of the bottle, or use a pharmacy product.
There is no evidence that extra virgin, organic or single-estate oil works better in the ear than any other plain olive oil, and we would not claim it does. Grade matters in the kitchen, not the ear. If you are buying olive oil for eating, our guide to choosing a quality olive oil covers what the label should tell you, and our explainer on unfiltered versus filtered olive oil explains the sediment question.
Why Sidr & Stone
To be plain: Sidr & Stone's olive oil is a food, sold for the kitchen — not an ear product, and we do not claim it works better in ears than any other plain olive oil. What we can tell you is what is in the bottle: an extra virgin, cold-pressed, unfiltered oil from our own single-estate farm on the plains outside Marrakech, Morocco.
- Single-estate — Sidr & Stone's olive oil comes from our own family-owned farm near Marrakech, and we control every step from tree to bottle, with no blending across origins.
- Rain-fed — our trees are not irrigated; they take what the season gives.
- Organically grown — no synthetic fertilisers, pesticides or herbicides are used (not yet certified; certification is in progress).
- Single harvest — a small, limited batch, picked when the fruit is ready; the current batch's harvest details are on the product page.
- Cold-pressed within hours of harvest — mechanical extraction only, with no solvents, refining or deodorising.
- Unfiltered extra virgin — minimally processed, so it may show natural sediment, which is normal.
- 100% natural — a single ingredient, olive oil, with nothing added.
- Dark glass with a gold label — protective packaging against light.
- 10% of profits to charity — a brand-wide commitment.
- Fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is the best olive oil — that would be the very kind of claim this article warns against. What we will say is that our oil is single-estate Moroccan, rain-fed, organically grown and cold-pressed within hours of harvest, and that the difference is there in the colour, the aroma and the taste. For its other uses beyond the kitchen, see our guide to olive oil for skin.
Frequently Asked Questions
Is olive oil good for your ears?
For softening earwax that is causing symptoms, yes — the NHS and HSE both recommend it. Healthy ears do not need it; they clear wax on their own.
How does olive oil help remove earwax?
It softens hardened wax so the ear's natural self-cleaning can move it out. It does not dissolve wax.
How long does olive oil take to clear earwax?
The NHS says lumps of wax should come out over about two weeks. If symptoms have not cleared after 5 days of drops, see the nurse at your GP surgery or a pharmacist.
Can I leave olive oil in my ear overnight?
The official method is 5 to 10 minutes lying on your side, then sitting up with a tissue to catch any excess. Neither the NHS nor the HSE suggests leaving oil in overnight.
Is Sidr & Stone's olive oil better for ears than pharmacy drops?
No, and we do not suggest using it that way — our oil is sold as a food. For ears, any plain olive oil or a pharmacy olive oil drop follows the same NHS routine.
Should I warm olive oil before putting it in my ear?
No. The NHS method does not call for warming, and heated oil can scald the thin skin of the ear canal. Room temperature is fine.
Where can I buy olive oil ear drops?
Pharmacies sell olive oil ear drops and sprays, and a pharmacist can advise which suits you.
Is olive oil a medicine?
No. Olive oil is a food, not a medicine. It has a long traditional history — including being honoured in the Prophetic Sunnah — and a substantial body of modern research, particularly around polyphenols, cardiovascular health, and the Mediterranean diet pattern. It can be a worthwhile part of a healthy routine, but it does not cure diseases and is not a substitute for medical care. Be cautious of any olive oil marketed with specific disease-cure claims.
Final Thoughts
Olive oil for ears earns its place in NHS advice because it is cheap, gentle and as good as the alternatives at softening stubborn wax. The evidence is modest, and the best-known study of long-term use is a warning against turning a short course into a nightly habit.
Follow the routine as written, keep oil out of any ear that hurts, discharges or may have a damaged eardrum, and let a pharmacist or practice nurse take over if five days of drops have not worked.
