Chili peppers can bring amazing flavor to all kinds of food, but there’s one thing you’ve got to watch out for: chili burn. Maybe it’s a spoonful of salsa that was a lot hotter than you expected. Maybe it’s a batch of jalapeños you chopped without gloves, and now your fingertips won’t quit. Either way, the fix is probably already in your fridge. Cold milk is the classic cure for a burning mouth, and for good reason. For burning hands, soak them in cool water or cold milk, then rub in a little vegetable oil if the sting hangs on.
Before we dig in, a word of caution: we aren’t doctors, so think of these as kitchen fixes. If your skin blisters, the pain is severe and keeps building, or a very hot pepper leaves you with chest pain, trouble breathing or repeated vomiting, get medical help.
How to stop a burning mouth
If you watch any extreme chili pepper eating videos, you’ll often see them running for milk the minute the pain gets intense. There’s a reason why. Dairy beats just about everything else when food scientists put capsaicin burn remedies to the test. In a 2024 study at Penn State, ice cream came out on top, with lassi, the Indian yogurt drink, right behind it.
Cold matters, too. Capsaicin sets off the same nerve sensor your mouth uses to detect painful heat. That’s why a hot pepper feels like a real burn. And temperature makes a difference in the tests. Cold drinks cooled the burn better than room-temperature ones, and in the Penn State study, warm water did the worst of anything tried. So pour your milk straight from the fridge, and skip anything warm until the fire’s out. Out of milk? Ice cream or yogurt will do the trick.
No dairy in the house? Grab something sweet. Researchers at UC Davis found that a sip of sugar water eased the burn about as well as cold milk. Stir about 2 tablespoons of sugar into a cup of water, or use any sugary drink you have on hand.
And give it a few minutes. Even without a drink, the burn fades on its own. The right drink just gets you there faster.
Why does milk help so much?
The old explanation is that milk is acidic. It’s a nice theory, but milk is close to neutral. What researchers think now is that several things help at once: capsaicin dissolves in fat, the proteins in milk help on their own, and cold takes the edge off. Take the protein: casein, the main protein in milk, latches onto capsaicin. In a 2023 study from the same Penn State lab, the more casein the researchers added to a capsaicin solution, the less free capsaicin was left, and the burn dropped right along with it. Casein did a better job than whey, milk’s other main protein. Ice cream has fat, protein and cold going for it, and it did best of all. Even skim milk works well, according to an earlier Penn State study, so fat is only part of the story.
Does water make chili burn worse?
You’ve probably heard that water just spreads the burn around. There’s a grain of truth to it, since capsaicin doesn’t mix well with water. But in the studies we’ve looked at, water still eased the burn, just less than milk did, and ice water beat room temperature. So if a glass of water is all you have, go ahead and drink it.
How to stop burning hands
Fingers on fire? Hands usually get it worst, since they’re the ones holding the knife. Here’s what to do:
- Soak them in cool water or cold milk. Either one helps. Cool tap water brought quick relief in a University of New Mexico study of hands burned by green chili peppers, and in a study of skin burned by pepper spray, milk worked just as well as water. If you go with milk, keep it cold, and swap in fresh milk from the fridge when it starts to warm up.
- Try vegetable oil if it hangs on. It’s sort of like fighting fire with fire, since capsaicin dissolves in oil. In the New Mexico study, the hand soaked in vegetable oil felt better over the long run. Rub a little cooking oil into your skin, or soak your fingertips in a small bowl of it.
- Wash with soap. Once the sting eases, wash up with soap and water to get the oil and any leftover pepper off.
- Keep your fingers away from your face. Until the burn fades, assume they still have pepper on them. That goes double for your eyes and your contacts.
What if it gets in your eyes?
Eyes are another level of misery, and they need their own treatment. Rinse with lots of clean water for a good 15 minutes, and check out our guide to jalapeño in your eye for the full rundown and when to see a doctor.
What about beer, lemon juice and other remedies?
A few other fixes get passed around. Here’s how they hold up:
- Beer. Capsaicin does dissolve in alcohol, so it sounds like it should work. In the UC Davis tests, though, a rinse about as strong as beer did no better than plain water. So save the beer for later.
- Lemon or lime juice. The idea is that acid cuts the burn, but we couldn’t find any research to back it up.
- Petroleum jelly. It shows up on lots of remedy lists, though we haven’t seen any evidence that it helps.
How to avoid chili burn next time
Want to skip all this next time? A few habits go a long way:
- Wear gloves. A box of disposable kitchen gloves is cheap insurance, especially with habaneros and anything hotter.
- Wash up right away. Scrub your hands as soon as you’re done chopping, gloves or not.
- Ease into new peppers. Taste a small bite before you add the rest, and keep something cold and creamy close by.

This past week I got a pretty nasty case of chili burn. We bought what we thought were sweet banana peppers. I started prepping some to pickle, no gloves because I thought they were sweet peppers. I noted they smelled strong, but kept going. Then my non-knife hand started to tingle and I knew I was in trouble. I tasted a pepper and it about blew my mouth out! It was significantly hotter than my jalapenos!!! I washed my hands and put on gloves, but it was already too late. The burn was so painful and it got both hands.… Read more »
My husband grew peppers, hot peppers to be exact, for more than the twenty years we were married. If he were alive, he would adamantly argue your opinion on water NOT helping with chili burn. HOWEVER, he would agree that regular tap water won’t help. Instead, he would tell you to try HOT water, as hot as you can stand because typically the hot pepper oils are in the pores of your tongue. The hot water opens those pores and allows the hot water to rinse the oils of the chili out of the pores. At least that’s how he… Read more »

Strawberries help to relieve chilli burn for me.
Baking Soda People. Scrub and wash hands with it. If it is still burning make a paste and let it sit.
For a hot mouth if you can’t or won’t drink cows milk. Take 8 oz warm water and 1 – 2 tsp of baking soda swish it around and spit out. This is also an old remedy (reduce to 1 tsp per warm cup of water) for acid indigestion or upset stomach. Just sip it.
I once inadvertently got severe chilli burn on my hands – I tried all the suggestions here with no relief. Then I read somewhere that Bicarbonate of Soda, or toothpaste can work to ease the burn. I had some bicarbonate of soda toothpaste to hand so I tried that and it really helped.
I often end up in severe oral pain because my SO “forgets” that’s he’s put chilli in something or leaves it spread over a food preparation surface. An amount that other people claim not to be able to detect leaves my mouth burning for hours. We’re both vegan so no dairy in the house and alcohol and fatty foods make me very ill. What’s my best option? I suck on ice cubes for a couple of hours, but as soon as I stop the pain returns. I’ve tried soy and oat milk but it doesn’t do anything. I enjoy eating… Read more »
I got burned on the hand for first time ever never felt pain like it an all my years of defence work or decades of full contact karate.

How about Apple Cider Vinegar? Very acidic. Gargle with and wash with? Try it and let me know!
As I was reading “Acidic liquids: Citrus juices can work here, especially lime juice and lemon juice. But of course, neither of these are pleasant to drink.” I was actually taking a sip of lemon juice. I love sour things as much as I love hot things.
