How to Get Rid of Fever Blisters

Fever blisters, also known as cold sores, are caused by the herpes simplex type 1 virus. An outbreak usually occurs on or around the mouth and typically heals within two to three weeks.

Fever blisters can be a lifelong irritant, since the virus remains dormant in the body throughout your life. Outbreaks can be triggered by stress, overexposure to sunlight, hormonal changes, trauma to the skin, or a weakened immune system.

Fever blisters are painful, accompanied by tingling and burning sensations along with swelling and inflammation. They appear as a cluster of small, white blisters and typically manifest on the same spot or area whenever the virus gets activated. Getting fever blisters can be a real pain and can even spoil your beauty.

There are many over-the-counter medicines for fever blisters, but they are not always effective and can take a lot of time. Instead, you can try some simple, natural home remedies that can help provide relief in just four to five days.

For best results, use these remedies as soon as you notice the initial tingling sensation. It will help reduce the duration and severity of an outbreak.

Here are the top 10 home remedies to get rid of fever blisters.

1. Tea Tree Oil

Tea tree oil can quickly and effectively treat fever blisters due to its antiviral properties.

  • Dilute tea tree oil by combining one part oil and three parts water. Using a cotton ball, apply the diluted tea tree oil on the affected area three times a day. Within a few days, the fever blister should heal completely.
  • Alternatively, mix equal amounts of tea tree oil and olive oil. Add a little bit of eucalyptus oil. Apply this solution on the blister three times daily for four to five days.

2. Whole Milk

Another very simple treatment for fever blisters is whole milk. Whole milk contains immunoglobulins and calcium, which help fight the virus that causes fever blisters. Plus, it has a type of fat known as monocaprin with antiviral properties. Milk also helps accelerate the healing process.

  • Soak a cotton ball in cold whole milk and apply the milk on the affected area. Leave it on for about 10 minutes. The cold milk will reduce the pain as well as soothe the tingling sensation. Do this several times a day for three to four days.
  • Also, drink a glass of warm whole milk with one teaspoon of turmeric in it two times a day for a week. Turmeric will help reduce the pain associated with fever blisters.

3. Hydrogen Peroxide

Hydrogen peroxide is a natural disinfection and hence very effective in killing bacteria that may infect the fever blisters. The herpes virus that causes fever blisters thrive in moist, warm environments; using hydrogen peroxide will keep the affected area dry and free of moisture.

  • Dip a cotton ball in 3% hydrogen peroxide solution and dab it over the blisters. Leave it on for a few minutes and then rinse the area with a wet washcloth and pat dry. Repeat this remedy three or four times a day for two to three days.
  • Alternatively, make a paste of two crushed aspirins and one teaspoon of 3% hydrogen peroxide. Apply the paste on the affected area using a cotton ball. Leave it on for just two to three minutes. Clean the area with lukewarm water. Do this once daily for not more than two days.

4. Ice

Cold compresses can alleviate pain significantly, as well as reduce the swelling and redness associated with fever blisters. It will also prevent the condition from spreading.

  1. Wrap a few ice cubes in a washcloth.
  2. Place it over the affected area for 10 to 15 minutes.
  3. Repeat this every three to four hours.
  4. After each session, apply a thick layer of lemon balm ointment to the area.

This remedy works best when used as soon as you feel the initial tenderness or a tingling sensation on your lip, which usually happens during the first few hours or a couple of days before the blisters develop.

5. Garlic

Garlic is one of those ingredients that you can rely upon when you want to get rid of fever blisters as fast as possible. Garlic has enzymes that work as antiviral agents that help treat fever blisters. Plus, its antibacterial properties will help disinfect the area and decrease the healing time.

  1. Gently crush two to three garlic cloves to make a paste.
  2. Apply it to your fever blisters.
  3. Leave it on for 10 to 15 minutes.
  4. Repeat the process three times a day for two days.

Warning: Garlic is potent and may sting a bit when applied.

6. Licorice

Licorice has an active ingredient called glycyrrhizin that has antiviral and anti-inflammatory properties that make this herb an effective treatment for fever blisters. It will minimize redness and swelling and also speed up the healing process.

  • Make a thick paste of one tablespoon of licorice root powder and one-half teaspoon of water. Dab the paste on the affected area using a cotton swab. Leave it on for a few hours. Reapply it three to four times a day for several days until the blisters heal completely.
  • You can also drink licorice root tea or take supplements to speed up the healing process.

Note: Those who have high blood pressure should avoid licorice remedies.

7. Tea Bags

Tea contains tannic acid, an astringent that has antiviral properties and hence can be used to get rid of fever blisters quickly. Also, tea has many vitamins and antioxidants that will help heal the blisters.

  1. Place a tea bag (black or green tea) in one cup of boiling water for one minute.
  2. Remove the tea bag and allow it to cool.
  3. Now press the tea bag on the affected area for a few minutes.
  4. Repeat this five or six times a day for three to four days.

This remedy will give you instant relief from pain and discomfort.

8. Toothpaste

Toothpaste contains ingredients like baking soda, hydrogen peroxide, alcohol and menthol that can help dry out blisters quickly. Plus, it has sodium lauryl sulfate that can help reduce the size of the blisters in just one or two days.

  • Apply a little bit of white toothpaste on the affected area. Leave it on overnight, or at least for two hours. Wash it off with a damp washcloth and then apply petroleum jelly. Follow this remedy once daily until the blisters heal completely.
  • Mix one teaspoon of white toothpaste and one-half tablespoon of salt. Using a cotton swab, apply the paste on the fever blisters before going to bed. Leave it on overnight and rinse it off with lukewarm water the next morning. Repeat daily as needed.

Note: For treating fever blisters, only use white toothpaste. Do not use whitening, gel, or colored toothpastes.

9. Aloe Vera

Aloe vera is another very effective way to treat fever blisters fast. It has natural healing powers and antibacterial properties that help disinfect the infected area. Plus, this herb is known to speed up healing and also reduce pain and inflammation.

  1. Cut an aloe vera leaf to extract the gel.
  2. Apply the gel on the affected area with your fingertips. Allow it to dry on its own.
  3. Then clean the area with lukewarm water and pat dry with a soft towel.
  4. Repeat the process several times a day for about three to four days.

This remedy will keep the infected area clean and soft so that the skin doesn’t split open, which can cause further infection.

10. Yogurt

Yogurt contains lysine that fights the virus that causes fever blisters. It even plays an important role in preventing the virus from becoming active. You can make an egg and yogurt facial mask to soothe and heal the blisters.

  1. Mix one egg, one cup of yogurt and one tablespoon of honey to form a thick paste.
  2. Apply the paste on the fever blisters using a cotton ball.
  3. Leave it on for half an hour, then rinse it off with lukewarm water.
  4. Repeat the process once daily as needed.

Also, try to eat one cup of yogurt two or three times a day to get rid of fever blisters quickly.

Be careful not to touch the fever blisters, and make sure to wash your hands regularly so that you do not spread this virus. Fever blisters are contagious, so it is highly recommended not to share lip gloss, drinks or food with others while you are having an outbreak.

  • Okay so here I am hello and thanks for all this advice I'm 25 and have struggled with these since I was a child I usually only get one and here and there randomly threw out the year or sometimes its months and months before I get another. If I like my lips it makes them worse and worse and I usually get them from a pimple that appears and like transformers into a blister I find that if I let my lips get as dry as possible apply rubbing alcohol and store bought cold sore treatment it slowly goes away. But today for the first time ever I have like 3 or 4 and they are just swelling more and more and it's horrible I also started my period today. I don't have tea tree oil or whole garlic I am going to try some of these that don't include those and will let you know how it works out. ☺ baby

  • It has always been my problem, whenever I had an attack of cough and flue or malaria ,it results intro fever blisters which are very painful.

  • Comment: i bilieve this will help those that cannot afford expensive meds. mix a strong toothpaste with a lil water and salt to create a smooth paste. apply on the blister and leave for 10 minutes then wash it off. this will help dry the blister and stop it from multiplying. after washing i applied olive oil on the blister.

  • After only an hour of using the tea tree oil, my fever blister went from the size of texas to hardly even noticeable. TEA TREE OIL WORKS WONDERS.

  • Toothpaste n Salt mixture works! I put on blister las nite. I awoke the next morning applied ice hydrogen peroxide n petroleum jelly went to work. I worried some because it still felt tender. But as the day went on. The pain subsided. The blisters are gone u cannot tell I had it unless I mention it! Thanks for the home remedy tip. The over the counter expensive meds do not work!!!

  • I have used for years and prevents cold sores is Lysine. I take it everyday 500mg. If you feel a cold sore coming on take 1000 twice a day. It helps to boost your immune system and works like magic. Either you won't get the sores or if you start feeling one, it might come out but does not hurt as much and lasts a shorter time.

  • I have to agree with other posters here. I started to get a fever blister yesterday and it hurt like hell. I put ice on it for 10 minutes and then applied Tree Tree Oil. I did this 3x yesterday and before going to bed I put lip balm on it to keep it moist throughout the night. I woke up today the pain was gone and the blister deflated. You cannot tell I ever had one. All I can say is magic! Thanks for all your post that help me. I have been getting these for over 20 years and they normally are on my lip for 2 weeks. Never again! Ice and Tree Tea oil!

  • Lavender oil is great for healing quickly too. Though does not seem to be a preventative solution.

  • i put on honey for 3 to 5 minutes then rinsed it off with warm water. thereafter i placed a thin coating of coconut oil over my lips. later on i repeated this but rinsed it off with lukewarm water and kept a cotton pad of soaked coconut oil onto the affected area. the inflamation decreased a lot, only it was a bit moist. after reading this list i decided to try the 3% hydrogen peroxide method.. dabbed peroxide onto the affected area for 5 minutes...waited 5 minutes n washed it off with lukewarm water. Dabbed it dry and ready to sleep.. hopefully this works well.. ill be updating my progress
    PS: (honey method not more than twice daily.. if decide to dab coconut oil as an independent method.. 3 to 4 times a day till the sore vanishes)
