Cold Sores / Fever Blisters

Cold sores, or fever blisters, are caused by a virus (Herpes Simplex Virus I) which those affected will have for life. Usually dormant, this virus can raise its ugly head at any time. Most often, those afflicted with cold sores can identify a trigger which initiates the lesion. Stress, sun exposure, or just a system that is run down from a cold, sickness, or fatigue.

Affected people know the signs of the imminent cold sore. Your lips tingle or sting, you may strike a bit of a fever or have a sore throat. These are called the prodrome, or premonitory symptoms. What can be done?

As I mentioned, you can’t get rid of a virus without dying: not a good option. But you can build up your immune response to minimize the frequency and/or duration of the outbreaks.

As mom and common sense would dictate

  • eat right (don’t skip breakfast with protein), hydrate often, and get plenty of sleep. Use appropriate medication such as prescription drugs from your dentist or medical doctor.
  • Take L-lysine daily. Lysine is one of the 20 basic amino acids needed to make protein. Lysine is important in collagen repair, calcium absorption, and transformation of fat to energy. Take 3 grams orally daily to prevent outbreaks and 9 grams daily during outbreaks.
  • Also acidophilus or a lactobacillus (good bacteria) capsules should be taken 2 at a time and every hour for at least the first few hours of an outbreak. This probiotic is one of the best digestive system supports.
  • Take a good vitamin B-complex, especially with Vitamin B-12. The B-vitamins are reduced with stress. These water soluble vitamins support the nervous system and the immune system. 3 doses of vitamin B-complex (50 mg) should be taken at the outbreak of a cold sore, then one dose daily to help prevent outbreaks.
  • Change tooth brushes frequently, at least every 3 months, more frequently when sick or with cold sore outbreak to prevent re-inoculation.
  • Take daily dose of Vitamin C & E to beef up immune system and support optimum health.

As with any infectious disease, wash hands frequently and avoid touching infected area. As with all infectious diseases, any of the above boxed precautions will help keep your immune system at its peak to reduce your chance for an outbreak or minimize the length of the outbreak of cold sores. Listen to your body.

Cold Sores and Alzheimer’s:

The virus which causes cold sores has been found in 90% of the amyloid plaques isolated from the brains of Alzheimer’s patients. These findings indicate that the cold sore virus is a major factor in the formation of these plaques. At least one study suggests that the use of antiviral drugs may be effective in slowing the progression of Alzheimer’s disease.

Good luck, keep brushing and flossing,
