Fever blisters and cold sores, herbal treatments and preventative herbal supplements


What are fever blisters and cold sores?

Fever blisters or cold sores are caused by the Herpes simplex virus (HSV-1).  Cold sores are just another name for fever blisters and this name originated because often fever blisters appear during the same time that a patient is suffering from a cold or flu. 

Fever blisters first appear three to ten days after exposure to the virus and an outbreak of fever blisters can last up to three weeks.  

Unfortunately, this virus remains in the body and moves into the nervous system.  Outbreaks can be triggered by stress, emotional trauma, a cold or a viral infection, exposure to sun and wind or a weakened immune system. 

Fever blisters are highly contagious and studies have shown that children as young as ten carry the virus. 

Symptoms of a fever blister outbreak

There are several warning signs that a fever blister is about to make its appearance, the most common being the tingling, itching feeling on the lips or around the lips.  As an outbreak of fever blisters usually go hand-in-hand with a weakened immune system, you might find that a day or two before your cold or flu starts, you will have an outbreak of fever blisters.

Having a fever and fatigue are also common symptoms of a fever blister outbreak.  Often the patient will complain of a sore throat and difficulty eating as well.  Fever blisters are easy to identify:  a group of blisters on a painful base that is often hot to the touch and very painful.  The blisters that form will dry up rapidly and leave scabs.  Depending on the severity of the infection, these scabs may last for a few days up to a few weeks.

Fever blister sores are not limited to the lips, it can sometimes be inside the mouth, on the face, and even inside or on the nose.   

There are several stages of the development of a fever blister: 

  •      Stage 1:  no sores are visible yet, but there is a tingling, prickling feeling around the affected area.
  •      Stage 2:  swelling starts and the affected area is red and often hot to the touch.
  •      Stage 3:  the first signs of tiny blisters appear and itching and pain increases.
  •      Stage 4:  a soft, very painful ulcer forms. 

What causes fever blisters?

Fever blisters or cold sores are caused by the Herpes simplex virus (HSV-1).

Herpes is a group of viruses that cause painful blisters and sores and the Herpes simplex virus can cause both cold sores around the mouth and genital area.  HSV-1 (herpes simplex virus 1) is responsible for fever blisters and HSV-2 (herpes simplex virus 2) is responsible for sores around the genital area.

HSV-1 is considered to be the most common herpes simplex virus and most people develop it in early childhood.

The Herpes viruses are known as neuroinvasive viruses which mean that they enter and hide in your body"s nervous system.  This unfortunately means that once you have contracted the Herpes simplex virus, you will be prone to outbreaks for the rest of your life.

Once you have contracted the Herpes simplex virus 1, a recurrence can be triggered by stress, fatigue, colds and flu, over-exposure to the sun and wind, a weakened immune system and even changes in hormones such as menstruation.

How do fever blisters spread?

Fever blisters are extremely contagious and can spread easily to other areas on the face. The HSV-1 virus spreads through direct contact, either skin contact or through contact with the oral secretions from fever blisters.  You can still pass on the virus even when fever blisters are not present.  You can transmit the virus by sharing eating utensils and glasses or cups.

If a person has fever blisters on the mouth, the Herpes simplex virus-1 can be transmitted during oral sex and cause herpes in the genital area.

Touching the fever blister and then touching a mucous membrane will also cause the virus to spread. Mucous membranes are the moist, protective linings found in areas of your body like the nose, eyes, and the inside of the mouth.

Wash your hands regularly to prevent the spread of the virus.

Do not share face towels and face cloths and discard your toothbrush after an outbreak of fever blisters as you might cause re-infection.

How can supplements help me?


The list of herbal supplements and herbal remedies listed here can all help to minimize future outbreaks and speed up the healing process.

The herbal supplements must all be used in combination and often results are seen within a few days.

The most useful and powerful of the herbal remedies recommended for fever blisters is the amino acid lysine.  

Lysine is an essential amino acid that the human body cannot synthesize on its own, therefore it needs to be obtained from your diet or from an herbal supplement.  Using a lysine supplement long-term can help to prevent fever blister outbreaks.  Increasing the availability of Lysine in the human body slows the virus replication and inhibits the use of Arginine, which is an amino acid that the Herpes simplex virus 1 utilizes.

Lysine is available in pill form and cream form.  At the onset of an outbreak of fever blisters, start with a dosage of 1000 mg Lysine daily and as the condition improves, take a therapeutic dosage of 500 mg daily.  Lysine cream can be applied topically to the affected areas to reduce the symptoms of painful outbreaks.

Supplement Recommendations

Supplement

Dosage

Lysine 1000 mg 3 times a day for flare-ups, then 500 mg a day as a therapeutic dose
Melissa cream Apply cream to the affected area 2-4 times a day
Vitamin C / Flavonoids 1000 mg vitamin C and 500 mg flavonoids 3 times a day

Echinacea / Goldenseal 200 mg echinacea and 125 mg goldenseal 4 times a day
Vitamin B complex 100-150 mg of each B-vitamin daily

Taking a Flaxseed oil supplement can assist in speeding up the healing process by promoting cell renewal.  Recent studies have shown that Vitamin C may be effective in treating fever blisters when applied topically.

Patients with recurring fever blister outbreaks can apply melissa cream regularly to prevent outbreaks.

The herbal supplement and herbal remedies listed here can all be used safely with prescription antiviral creams such as acyclovir, which also promotes the healing of fever blisters.

Other recommendations

Using a protective lip balm with an SPF of 15 or higher can prevent fever blister outbreaks.

As mentioned before, do not touch the blisters as you will spread the infection.

Holding an ice cube on the affected areas can help to reduce the pain and swelling associated with fever blisters.

Try to avoid foods that contain the amino acid arginine.  As mentioned, arginine is used by the Herpes simplex virus.  These foods include nuts, chocolate, whole-grain cereals and gelatine.
