Cold sores and fever blisters are the same. The herpes simplex virus causes them, and they’re quite contagious. Cold sores usually last about seven to ten days. They start with a tingling feeling around the outside of your lip and turn into red, raised, fluid-filled blisters within a day or two. In rare cases, a cold sore can form inside your mouth, on your nose, or your chin. Cold sores can take up to twenty days to develop after exposure.
There are two types of herpes simplex viruses to be aware of: Type 1 and type 2. Type 1 causes cold sores, and types 2 is the genital version. Either type can cause sores on both the facial areas and the genitals, though. Once you’ve got a cold sore at least once, the virus stays in your skin and can crop up again throughout the years. Sometimes stress or menstruation can trigger outbreaks.
Cold sores often clear up on their own, though, unless you have a weakened immune system. Herbal approaches to treatment include disinfecting the sores and helping the immune system fight the virus.
Black Walnut is the herb of choice to use for cold sores and fever blisters. This herb is an antiseptic that is high in natural iodine and can use both externally and internally to treat cold sores. It too can be applied to the sores several times each day, and the juice can be drunk as well.
Comfrey salve will help heal the cold sores as well. This is a cell proliferant which helps your body heal very quickly. Prick the cold sores and apply comfrey salve externally for the best results.
Remember that cold sores and fever blisters are quite contagious, mainly when a sore is present, so you should avoid contact with babies and anyone who has a weakened immune system from diseases such as HIV and Diabetes.
When you have active sores, be sure to keep your hands clean and avoid contact with other areas of your body, such as the eyes and genital areas. Also, be sure to sterilize or replace your toothbrush when outbreaks occur, and of course, avoid kissing anyone until you healed.
