Cold sores or fever blisters have nothing to do with cold or fever. Cold sores are caused by HSV viral infection and take up to 10 days to recover naturally.
Once you have a cold sore, you become incredibly contagious. People coming in contact with you can get these too if they are prone to HSV. So, no kissing your loved ones until the yellow crusts over the blisters fall off completely. 
But, the thing is not all of us are vulnerable to HSV virus. Only 90% of the people get affected by it. If you are blessed, you will get it once, and your body will grow an immune system against it.

suggesting; you use essential oils for cold sores.

What is essential Oil?
If you are somebody whose olfactory nerves are working correctly, you must have smelled the beautiful aroma or fragrance of any flowers, fruits or plants now and then. 
These smells are naturally occurring volatile aromatic compounds. We find these in different parts of the plant, say, seed, stem, flower, kernel, root, leaves, flowers or any other part. 
These aromatic compounds are called essential oil and are volatile. Due to the volatile nature of this oil, if stored, these oils start losing their fragrances gradually. [6,7]
Scientists have identified around 3000 different types of essential oils until this day. Most of these are helpful for humans in different ways.
We use a number of these for DIY skin, hair care products, and various home remedies.

• Always use a sterilizes and clean cotton swab or bud to apply the essential oil on your skin. Do not forget to dispose of the used cotton bud or swab and be very careful so that the used swab does not touch any of your body parts.
• In case of strong essential oils, use water or carrier oils like olive oil and coconut oil to dilute the oil before using.
• In case of having sensitive skin, you should dilute even the milder oils, just to be safe.
• If your cold sore is severe, painful, and does not go away even after using home remedies, you need to see a doctor.
We all love to incorporate natural and chemical free remedies to solve our health issues as long as possible. But you need to remember that, these might not be enough in some cases. In case of that, you should contact your physician.
Some of these oils can work slowly than popular antibiotics, but you have to be patient. True, most of these do not have any side effects, but sometimes these remedies can take some time.
