I was also starting to get frequent cold sores... Every couple of months and I felt terrible with them. So, I was doing some research and read on Dr. Mercola's website that if you take Red Marine Algae( with gigartina/dumontacea in the formula) that this will help prevent you from getting the cold sores. So far, so good. It's been a couple of months and no signs of an episode.

Red Marine Algae (difficult to find outside of the USA) and L-Lysine taken in the early stages of a heperes outbreak works wonders, even regarding furture break-outs!

To my surprise, this worked really well. I just applied it several times a day and it went away.

Rubbing Alcohol, Vitamin C

Aloha, I love your site! Many people here use acetone, for cold sores, but I never have. Instead, I use rubbing alcohol as SOON as I feel the tingling/swelling. I apply it using a qtip or a cotton ball, and it almost immediately stops the swelling. Apply at least once an hour for the first day. I also use tea tree oil, lavender oil, and oregano oil - usually diluted in rubbing alcohol. This combination usually prevents a blister from ever forming, but you have to keep on it. This allows me to keep working and interacting with the outside world without embarassment.

Vitamin C taken in massive quantities is also crucial - I think the dip in my immune system that happens after a few weeks of not enough sleep and too much stress is what triggers an outbreak. I used to get four outbreaks a year - since I started using rubbing alcohol and vitamin c, it's down to one every year, often one every two years. This is also because I'm very proactive - if I notice that I'm feeling tired on a regular basis, I start taking Vitamin C to protect my health. It's really helped, and makes the outbreaks, if they come at all, much smaller and much more manageable.

Sauerkraut Juice

I suffered from cold sores for many years. Then I read about a cure that used sauerkraut juice to cure them. I tried it at several outbreaks and they quickly disappeared. It may be the L-lysine in the juice. They went away and have not come back for years.

Sweet Orange Oil

Put drop or two of Sweet Orange Oil (Citrus sinensis) on the "fat/cracked lip" just before bed. Cures the problem overnight! This is a painless, tried and true remedy that I've given to many people. Some gentlemen note that, while the oil does NOT burn the lip, any of the oil that drips down onto shaved parts of the face will cause a rather nasty burning sensation. The solution is to smear some lavender oil below the lip, BEFORE applying the orange oil, to keep this from happening. Olive oil or most veg oils will also work but lavender oil works best. Since this burning sensation is rather common, anyone who shaves below the lip always should use the lavender oil first, then apply the sweet orange oil to the lip. If orange oil is not available, zest a little of the peel of an orange and apply to the lip. Anyone who tries this remedy, please email me and tell me how it worked.

Tea Bag

Tea bag soaked in cold water stops cold sores and fever blisters. I think the tannic acid is what does it. Just soak bag a few minutes then squeeze it slightly and apply. Apply as often as you can through out the day. Really soothes and takes out the pain and swelling. Put bag in a dish or cup to keep moist. If you keep it in the fridge it will keep cool and feel better.

I have had clients who had very good success using Earl Grey tea bags as a compress for the cold sore. Wet a tea bag in barely warm water, squeeze just a little until not dripping and then use as a compress for 20 minutes at a time several times a day. The bergamont oil and tannins in the tea should heal the sore.

Tea Tree Oil

I have been using tea tree oil to treat cold sores for well over a decade - it has never failed me. As a child I was very susceptible to enormous cold sore breakouts and my parents tried all kinds of natural as well as not-so natural remedies to no prevail? In my early sdulthood I decided to try applying un-dilluted te tree oil & magic! Undilluted tea tree oil is very string and can even burn your skin, so it is important to be precise & apply it only to the direct affected spot, without letting it run or spread over a larger area. A doused q-tip works well. If you apply it (and re-apply it several times, ie. every hour) when you get the first tickling sensation of a cold sore coming on before it actually appears, it will never appear! If you are a bit lit and the cold sore has already shown its face, apply it, and the sore will quickly dry up and die without going through the whole itchy raw stage?

Cleaning with diluted tea tree oil and regular dabbing of the affected area. Drys it right up.. The cold sore should be gone within about 4 days.

I have had real good luck with keeping my herpes lesions from beginning full blown sores. When you begin to feel the tingling of an episode, or even if they are there but not leaking fluid, dab on tea tree oil with your fingers straight out of the bottle. This will reduce and totally eliminate the sore. Otherwise, the episode takes 2 to 3 weeks to get over. I have my sores on my butt cheeks, so don't know how the tea tree oil would act on tender genital tissues?

ACV or Tea Tree Oil to cure cold sores.

I used ACV on a q-tip pressing firmly, and repeated several times throughout the day. This began to dry up the cold sore on my upper lip after only a few hours...however, it caused a bit of skin irritation around the area which kind of defeated the purpose (i have very sensitive skin). So the next day I switched to tea tree oil applied with a q-tip (making sure to use new q-tips for each application). Cold sore is almost completely dried and the irritation from the ACV is dissapearing.

Cold sores/fever blisters I've been suffering with this problem over & over for quite some time and wasn't having any luck with the OTC stuff or Valtrax for that matter. I tried the H2O2 on its own & mixed with a crushed up L-Lysine tab (took FOREVER to crush into powder) the last time this happened but this time it seemed to come back stronger than ever. In a true moment of desperation I put 3 drops of Tea Tree Oil (TTO) into a dixie cup full of H2O2 grabbed some q-tips and (one by one never re-using) applied it to the cold sore over and over and over and over. I pressed the q-tip up against it hard and massaged it in. I swabbed my lips with it and the inside of my mouth. This process took about an hour but by the time I stopped the cold sore had gone from itching, oozing & weeping to white "bubbles" to dry crust/scab. I think I may start using TTO, baking soda & H2O2 as my new toothpaste and baking soda w TTO as my new "soap"!
