When this virus becomes activated, it will cause painful red blisters around the mouth area. Once these blisters rupture, they will leave large, red sores which are prone to bacterial infections.

The healing process starts when a crust begins to form over the fever blister, but when this happens cracking and bleeding are common. One good thing is that after a fever blister finally heals, there is typically no visible sign of damaged tissue.

A common home remedy for fever blister is the application of ice to the sore. When applied for approximately ten minutes every hour, this solution may prevent the fever blister from developing any further. Other substances you can apply which may help are witch hazel and spirit of camphor.

Changing your diet during an outbreak may also work as a home remedy for fever blister. Cutting back on acidic and salty foods, drinks with caffeine, and foods like chocolate, peanuts, oatmeal and anything else that is high in arginine can shorten the healing time of the fever blisters. Adding B12 and folic acid into your diet can also help shorten healing time.

Probably the easiest home remedy for fever blister is, with clean hands, moisten your fingers and press them into common salt. Apply to the fever blister for 30 seconds or so. Just as gargling warm salt water can help sore throat and canker sores, placing salt on fever blisters may reduce healing time.

Fever blisters can last up to 14 days. However, if you find the home remedy for fever blister you try isn't working and the outbreak is lasting longer than two weeks, seeking medical advice may be advantageous.
