Repel insects

Rubbing an onion on your skin is a simple way to repel bugs.

Soothe insect bites and stings

Forgot to follow tip #1? Rubbing onion onto bug bites will help to ease the pain.

Soothe a sore throat

Making onion tea is a great remedy for soothing sore throats. On the stovetop, boil water with onion peels in it (about 1 cup of water for the peels of 1/2 an onion.) Bring to a boil, remove onion and serve.

Ease the pain from burns

Rubbing onions onto burns helps to soothe the pain.

Remove splinters

Have a splinter that just won’t budge? Try taping (yes, with tape, or an adhesive bandage) a piece of raw onion to it. Hold tight for about an hour before removing the onion.

Clear an irritant from the eye

Anyone who has ever cut an onion in an enclosed room knows that it’s sure to make you cry unless you jump through hoops to prevent the acrid sulfur emanating from the cut onion from reaching your eye, such as putting on fans or submerging them in cold milk or water. This can be an annoyance, but it can also come in handy if you have debris or other irritant caught in your eye. In this case instead of rubbing your eye and risking worsening your condition, cut an onion in half, take half the onion and hold it directly below the irritated eye and let the tears flow and help to clear the debris from the eye.

Treat vomiting

Gobbling down an onion may be the last thing you want to do when you’re feeling nauseated. However, if you feel like you’re going to vomit or have been vomiting, onions may be able to help. Try this: Grate and strain the liquid from one whole white onion, brew a mug of peppermint tea, measure out two teaspoons of onion juice and drink it down. After five minutes, drink the mug of tea. Repeat this process until vomiting stops and nausea ebbs away.

Remove warts

With so many wart removal cures available over-the-counter that contain strong acids or freezing implements that can harm healthy skin around the wart and cause painful irritation, why not try for a gentler method that comes from nature — and is far less expensive than the pricey chemical alternatives. Cut a sliver of onion flesh just the same size as the wart and place the onion onto the wart and secure in place with a small bandage. Change the onion piece and bandage daily, and within days, the wart will be gone.

Improve your hair growth

Onion juice can help you re-grow your hair and make it stronger. This is attributed to the sulfur content which is one of the main building blocks of hair. It improves blood circulation and provides the hair follicles with sufficient nourishment. Onion also has anti-bacterial properties, so it helps with scalp infections that might contribute to hair loss.

Kill intestinal parasites

The sulfur compounds in onions are anti-parasitic. Onion juice is very effective for intestinal worms, especially tapeworm and thread worms. Drink 2 tsp. of onion juice twice a day for 2 weeks.

Relieve wisdom teeth pain

Chewing on onion is another tested home remedy. If chewing proves to be too painful for you, place a slice of onion on the sore area. Alternatively, you can extract some onion juice and dab it on. Shallots, red and yellow onions tend to be more effective compared to white and sweet onions.

Heal small wounds

Onions even work on cuts! Peel some onion skins and use to seal up small wounds. This will speed up healing and minimize bleeding too!

Fight menstrual cramps

Onions are nature’s potent painkillers. They can help soothe a woman’s menstrual cramps if she consumes raw onions a few days before her menstrual cycle.

Get rid of skin pigmentation

People suffering from dark spots and pigments on their face can apply an onion and turmeric juice on the troubled spot to help brighten their skin.

Remove earwax and earache

If you have an excess buildup of earwax or suffer from earache, you may resort to extreme measures from time to time to keep it under control. If drugstore remedies haven’t worked for you, why not give an onion a chance to do what chemical concoctions have failed to do? Carve up an onion, reserving the innermost core. Cut the core of the onion into an ear canal sized plug, making sure it is long enough to grip easily. Place the onion core into your ear and leave it in place overnight. When you awaken, remove the onion piece and cleanse the ear. Your wax will come right out!
