How to Relief Cold Sores on lip

Cold sores are not caused by common cold as most of us think. They are caused by Herpes Simplex Virus Type 1 or simply HSV-1, which is passed on through contact with infected skin or body fluid. A cold sores caused by skin damage as the virus multiplies within the cells it has infected on the lip.

It starts with a warning of red, irritated skin and itchy, painful blisters which form, break down and crust over before, healing. This lasts about a week. then after the first infection, the virus enters a nerve cell and travels up until it comes to a collection of nerve cells where it resides quietly in a dormant stage until it's reactivated. It then starts to multiply again and travels down the nerve to skin and causes the cold sores.

The factors that reactivate the virus include stress, sunlight, fever, hence the name 'fever blister' and hormonal changes like those that occur around your periods.

Cold sores are most contagious when the blisters are present and just after they break until the skin is completely healed and looks normal again. Some people transmit the virus through saliva even if they never get cold sores. The virus is also present on an infected person's lip, even if there is no obvious sore. This explains why many of us are infected through kisses from relatives or lovers.

Also, because HSV-1 can live in saliva, sharing personal items such as utensils or drinking glasses can also cause infection. Oral intercourse can also cause HSV-1 infection on a partners privates. Although not common, cold sores can occur on the neck, chin or nose and reappear in the same area each time for most people.

A cold sore on the finger is called herpetic whitlow and that on the eye is called ocular herpes. It can cause blindness thus prompt treatment is needed to prevent eye damage.

  3. A cold sore is not welcome on your face, or anywhere else, for that matter. Not only are they cosmetically unappealing, they can be downright painful. Let’s get over the fact they’re caused by the herpes virus. We all know it, and that aspect gets far too much attention. Defining cold sores simply for what they are, they are small, fluid filled lesions that pop up generally on or around your lips. The blisters often group together, and after they break, a crust forms over the resulting sore. There is no true cure for the virus, or the cold sores.

"As Jack slept, the beans germinated in the soil, and by morning a big beanstalk grew in their place. When Jack saw the great beanstalk, he immediately decided to climb..." This is a classic scenario of 'Jack and the Beanstalk' fairy tale. The same is true for Kenya's bean variety that climbs and spreads on sticks producing double the yield of local varieties.

Due to subdivision of land in Kenya, farmers are not able to produce enough beans to feed the 38.6 million people living in Kenya.This is mainly due to shrinking land sizes.

Herbal Plants used for Alternative Medicine with no side effect

He recommends taking a glass in the morning and in the evening for preventive measures. 
He cautions on their medicinal uses which should be considered as neither preparation methods nor dosage prescription are provided. This is a topic that would require much more time and I have decided to leave it for part two of this article.
