Olive Oil for a Sore Throat: Tradition, the Oleocanthal Sting, and the Evidence
Olive oil for a sore throat is one of the oldest kitchen-cupboard ideas there is: a spoonful taken neat, a little stirred into warm water with lemon, the bottle reached for because a parent or grandparent always did. The honest answer is short. No clinical trial has tested olive oil for a sore throat, so nobody can tell you it helps — and we will not. What we can do is show you what the tradition is, why a fresh extra virgin oil makes the back of your throat sting, what the famous 2005 laboratory finding did and did not measure, and when a sore throat needs a doctor rather than a spoon.

The Short Answer
- A PubMed search for this article found no clinical trial of olive oil for a sore throat or pharyngitis. Pages saying olive oil "soothes" a sore throat are repeating tradition, not reporting a result.
- The tradition is real: a 2025 questionnaire of 475 Saudi families found olive oil among the two most common home remedies for children's cough, alongside sesame oil — self-reported, with no comparison group.
- The peppery sting of fresh extra virgin olive oil comes from oleocanthal, which activates a receptor, TRPA1, found in the mouth almost only in the throat (Peyrot des Gachons and colleagues, Journal of Neuroscience, 2011).
- The 2005 Nature paper linking oleocanthal to ibuprofen was a laboratory and taste study. Nobody was treated, and the researchers put 50 g of oil a day at roughly a tenth of an adult ibuprofen dose.
- Olive oil is a food, not a medicine. The NHS advises seeing a GP if a sore throat has not improved after a week, and calling 999 for any difficulty breathing or swallowing.
Is Olive Oil Good for a Sore Throat?
There is no clinical evidence either way. No published trial has given people with a sore throat olive oil and measured whether their symptoms changed, so the honest answer is that it is untested. A spoonful of good extra virgin oil is a food most adults can take without harm — a statement about safety as food, not a claim that it does anything for a throat.
That matters because several top search results say otherwise, describing sips of olive oil through the day as a way to calm a throat and quiet a cough. None cites a study, because there is none to cite.
The Tradition: Where the Spoonful Comes From
Olive oil has been a household staple across the Mediterranean, the Middle East and North Africa for millennia, and it found its way into home care for colds — taken neat, warmed with lemon, mixed with honey. These are family customs, and they are still in use.
Yousef and colleagues, in Materia Socio-Medica in 2025, surveyed 475 families across five regions of Saudi Arabia about home remedies for children's cough. Sesame oil and olive oil were the most commonly used, and most advice came from family and friends. It is a cross-sectional questionnaire with self-rated improvement and no control group: it tells us what families do, not whether the remedy made any difference.
For many readers the olive also carries a deeper meaning. The Qur'an describes a lamp "lit from [the oil of] a blessed olive tree, neither of the east nor of the west" (Surah An-Nur, 24:35, Sahih International); our guide to olive oil in the Qur'an and the Sunnah sets out the texts with care. That reverence stands on its own. It is not a medical prescription for a sore throat, and we do not present it as one.
Why Fresh Olive Oil Stings the Back of Your Throat
Anyone who has tasted a genuinely fresh extra virgin oil knows the peppery catch at the back of the throat, sometimes with a cough. Peyrot des Gachons and colleagues, in the Journal of Neuroscience in 2011 (31(3):999–1009), showed that oleocanthal — a phenolic compound formed when olives are crushed — selectively activates one sensory channel, TRPA1, and that within the mouth this receptor sits almost exclusively in the pharynx. Chilli irritates the whole mouth; oleocanthal is felt in the throat alone.
The work combined cell experiments, rodent studies and human sensory tests. It explains a sensation; it does not measure any effect on a sore throat. It also suggests a practical caution the tradition rarely mentions: the fresher and more pungent the oil, the stronger the sting, so on a raw throat a very peppery oil may simply make you cough. Our piece on oleocanthal covers the chemistry in depth.
What the 2005 "Ibuprofen" Finding Actually Measured
Olive oil keeps appearing in sore-throat articles because of a one-page paper. Beauchamp and colleagues, in Nature in 2005 (437:45–46), noticed that fresh oil stung the throat much as liquid ibuprofen does, identified oleocanthal as the cause, and reported that in the laboratory it inhibits the same cyclooxygenase enzymes.
Nobody in that study was given olive oil for a symptom, and no clinical outcome was recorded. In Nature's news coverage, the researchers estimated that 50 g of oil a day — about four tablespoons — would supply around 10% of the adult ibuprofen dose for pain relief. A tenth of a dose is not a tenth of an effect, and a food is not a painkiller.
| What people say | What has actually been studied | What it cannot tell you |
|---|---|---|
| "Olive oil soothes a sore throat" | No trial found; a 2025 survey of 475 families shows wide home use for children's cough | Whether it changes symptoms at all |
| "It stings because it's working" | Oleocanthal activates TRPA1, concentrated in the throat (2011 cell, animal and sensory work) | That the sting helps an inflamed throat |
| "It works like ibuprofen" | Shared enzyme inhibition in the laboratory (2005, Nature) | Any effect in a person — no one was treated |
| "Mix it with honey" | Honey studied on its own for cold symptoms (2021 meta-analysis, 14 studies) | Anything about olive oil or the mixture |
Honey, Lemon and the Mixture People Actually Make
Most home versions add honey and lemon, and honey has a research base olive oil lacks. Abuelgasim, Albury and Lee, in BMJ Evidence-Based Medicine in 2021, pooled 14 studies of honey for upper respiratory tract infections and found it improved cough frequency and severity compared with usual care; risk of bias was moderate, and the two placebo-controlled studies they combined showed no clear difference.
So if a warm lemon-and-honey drink helps you feel better, the honey is the part with some evidence behind it. Olive oil stirred in adds richness, not a proven ingredient. The NHS advises against giving honey to babies under 12 months. Our article on olive oil, lemon and honey looks at the morning version of this mix.
What the NHS Recommends — and When to See a GP
The NHS describes sore throats as very common, usually getting better by themselves within a week. Its self-care advice: gargle with warm salty water (adults only), drink plenty of water, eat cool or soft foods, avoid smoky places, suck ice cubes or hard sweets (not for young children), and rest. Antibiotics are not normally needed. A spoonful of olive oil eaten as food alongside that is fine; it should never stand in for medical advice.
See a GP if a sore throat has not improved after a week, if you get sore throats often, or if a child under five has one. Call 111 or ask for an urgent appointment if you are worried, have a very high temperature or a weakened immune system. Call 999 for any difficulty breathing or swallowing, drooling, or a high-pitched sound when breathing. In Ireland, your GP and the HSE are the equivalent route.
The Objections Worth Taking Seriously
"My family has used it for generations." That counts: it tells you olive oil is a trusted food and a comforting ritual. It cannot tell you whether the throat would have felt the same without it — most sore throats improve within days regardless, and only a controlled trial could separate the two.
"Oleocanthal is anti-inflammatory, so surely it helps." A shared action on an enzyme in a laboratory is a starting point, not a result, and nobody has tested it on a sore throat. Our article on olive oil and inflammation sets out what the wider research does support.
"Why is an olive oil company writing about this?" Because people search for it and deserve a straight answer. We sell olive oil as a food worth eating well, and would rather be trusted on that than have you believe something about your throat nobody has shown. If you do reach for it, choose a genuine extra virgin oil in dark glass with a harvest date — our guide to choosing a quality olive oil explains why.
Why Sidr & Stone
We make olive oil to be eaten, not prescribed. Everything below describes how Sidr & Stone olive oil is grown and made — not anything it does for a throat.
- Single-estate — Sidr & Stone olive oil comes from our own family-owned farm near Marrakech, Morocco, and we control every step from tree to bottle.
- Rain-fed — no irrigation; the trees take what the season gives them.
- Organically grown — no synthetic fertilisers, pesticides or herbicides.
- Single harvest — a small, limited batch, picked when the fruit is ready.
- Cold-pressed within hours of harvest — when the phenolic compounds behind that peppery catch either survive into the bottle or do not.
- Unfiltered extra virgin — minimally processed; a little natural sediment is normal.
- 100% natural — a single ingredient, nothing added.
- 500 ml dark glass with a gold label — protective packaging against light.
- 10% of profits to charity — a commitment across every Sidr & Stone product.
- Fulfilment in the UK, EU, and US.
We will not tell you Sidr & Stone is the best olive oil for a sore throat — no olive oil has earned that claim. 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 we publish no polyphenol or oleocanthal figure because the current batch has not yet been analysed.
Frequently Asked Questions
Does olive oil help a sore throat?
No clinical trial has tested it, so there is no evidence that it does. It is widely used as a home remedy, but that shows the tradition, not an effect. See a GP if a sore throat has not improved after a week.
Why does olive oil burn my throat?
Fresh extra virgin olive oil contains oleocanthal, which activates the TRPA1 receptor found in the mouth almost only in the throat (Journal of Neuroscience, 2011). The sting is a normal feature of a fresh, pungent oil.
Is it safe to take a spoonful of olive oil with a sore throat?
For most adults a spoonful of olive oil is simply food, though a very peppery oil may make a raw throat cough. If you have a medical condition or take regular medication, ask your GP or pharmacist about home remedies.
Is olive oil good for a cough?
There is no clinical trial of olive oil for cough either; the 2025 Saudi survey measured use, not effect. The NHS advises seeing a GP about a cough lasting more than three weeks.
Is honey better than olive oil for a sore throat?
Honey has more evidence: a 2021 meta-analysis of 14 studies found it improved cough symptoms compared with usual care, with moderate risk of bias. Olive oil has not been tested. Never give honey to babies under 12 months.
Does olive oil work like ibuprofen?
Only in a narrow laboratory sense: oleocanthal inhibits the same enzymes, but no one in the 2005 study was treated, and 50 g of oil was estimated at about a tenth of an adult dose. Olive oil is not an alternative to any medicine.
Where can I buy Sidr & Stone olive oil?
Directly from our website, as a pre-order from the current limited single-harvest batch, with estimated shipping from November 2026 and fulfilment in the UK, EU, and US.
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 a sore throat is a genuine tradition with a genuinely interesting piece of science attached — a compound that stings one small part of the throat because of one receptor in one place. What it lacks is a trial showing it helps, and the most-cited finding behind the idea was a laboratory comparison in which nobody was treated.
So look after a sore throat the way the NHS suggests — fluids, rest, soft food, time — and see a GP if it lingers past a week or you are worried. If a spoonful of good olive oil is part of how your family eats when someone is unwell, enjoy it as food. Just do not let anyone sell it to you as a cure.
