Fever blisters, also known as cold sores, start as painful red bumps, normally around the mouth. They are filled with fluid and eventually break open to reveal a larger blemish. Fever blisters are caused by the herpes simplex virus, which is highly contagious. There are many OTC remedies for fever blisters; however, treating fever blisters at home is also effective and can provide much-desired relief.
Step 1
Apply a warm or cold compress to the fever blister. This helps to ease pain, according to the Mayo Clinic website. A cold compress may also reduce swelling associated with cold sores. Moisten a clean cloth with cool or hot water and hold it against the blister for up to five minutes.
Step 2
Cleanse your fever blister two times daily and dry it thoroughly. This will minimize the risk of further infection or of spreading the virus to other parts of the face. Do not squeeze or pick at the fever blister.
Step 3
Use a cotton swab to apply a thin coat of petroleum jelly to your fever blister. This provides protection needed for healing as the fever blister begins to dry out. Make sure to dispose of the used swab in the trash after use. Do not reuse it.
Step 4
Avoid chocolate, cola, peas, grain cereals, peanuts, gelatin, cashews and beer. These foods contain arginine, an amino acid necessary for the lifespan of the herpes simplex virus. Cutting out these foods while you have a fever blister will deprive the virus of nutrients it requires and help to eliminate it from your system.
Step 5
Apply witch hazel to the blister. Witch hazel aids in drying out the cold sore and speeding up the healing process, according to MotherNature.com. Rubbing alcohol provides the same benefit; however alcohol may sting more than witch hazel when it is applied.
