An Onion a Day… (Bruise Remedy)

last updated on 3 November 2011

Using a raw onion for bruises is an old and traditional remedy.

Onions are great for treating bruises because they have both analgesic (pain relieving) and anti-inflammatory properties.

There’s two popular ways to use onions for bruises. One is simple and very straightforward. The other one requires a bit more effort — but appears to be much more effective.

Whichever method you choose, it’s important not to place the raw onion over any open wounds or cuts (only the bruise, okay?).

The Lazy Method: Slice a raw onion and place it over the bruise. Leave this for 15-20 minutes.

The Enterprising Method: Dice a raw onion. Put one half in a bowl and add 2-3 tablespoons of plain salt. Mix this up well. You’ll need some kind of cloth, towel or bandage. (Do this part in the bathroom since it will get messy. ) Apply the onion mixture over the bruise and wrap the makeshift bandage over to hold it in place.

Tie it firmly so that the onion mix doesn’t fall out. Leave this on overnight. You’ll find the next day that the bruise (along with the pain and swelling) will have gone down significantly.

    This is such a cool idea and so simple. Being an extremely clumsy person who bumps on everything things that screams Corner, this will come in handy! Onions rock! (except when they break your heart and make you cry)

    My relfexologist recommended this. It works WONDERS! I got kicked by a horse and had a nasty bruise. It took 2 nights but the bruise was 100% gone.

    I have a nasty black eye, can I use an onion on it?

      In theory, it should work on a black eye. But fumes from the onion might be too strong to make it comfortable. If you’re really careful to keep the onion at the periphery, it could work…

      I would recommend that you chill the onion first. The fumes will be dormant until the heat of your body warms the onion. Salting the onion also helps. If it gets to be too much, try an eye mask that you can chill. Good luck!

    We placed a very thin raw onion slice on my 2″ diameter bruise on my very swollen leg then wrapped it with cellophane overnight. The results were successful in reducing swelling and diminishing the color and pain of the bruise. I’m going to add salt to a cold onion overnight for additional results..
