Last Monday I had a cold sore outbreak in my upper lip (I started feeling the tingly sensation) , so immediately I looked for remedies in this website and I opted to use the Hydrogen Peroxide. Let me tell you it is a wonderful remedy for cold sore, by wednesday the cold sore was completely dry and it got never bigger than half size of a lentil bean. I had outbreaks before (usually when I am stressed) and it was a nightmare, the cold sore lasted for weeks ( I am not kidding) and it got as big as half of my upper lip. The treatment is extremely easy and cheap: damp a q-tip or cotton swab with the HP and apply to the area as many times as you can. i did it every 3 hours. Thanks earth clinic for such helpful information

My Mother suffered from cold sores, My Great grandmother always said use your own ear wax. Grandma was from the Old Country..When I got married my husband suffered with cold sores, So I told him what grandma used to say to mom. Use your ear wax. After many Years of going thru this. I told him again and also saying i will not tell you again and to just suffer. Well to my surprise he tried it and from then on. he was telling all of his friends. My last words were not to lick your lips.

Olive Leaf Extract

Hi Everyone ~ I discovered Olive Leaf Extract (I use the one by 'Herb Pharm', purchased at Whole Foods Market - haven't tried other brands. Well, all my life, I would get at least two terrible cold sores per year. Even after two weeks of looking awful, I would be left with a scar for at least a month...I was so upset every time. They were the bane of my existence!

The very first time I tried Olive leaf extract, I was on the verge of another cold sore. I put about 2-3 droppers full in a small amount of water. Within moments I could feel the initial swelling going away. I ran to the mirror because I thought I was imagining things! I wasn't! The nasty little thing was disappearing before my eyes.

It's been 4 years now and I've had only one (pretty mild) cold sore and all because I hadn't taken the olive leaf at the first signs of fatigue, dry lips, and a feeling of being 'run-down' which always precedes the outbreak. My Mom also had these her whole life, and it works wonders for her too. The key is to use it preventatively, as well as extra doses at the onset of a breakout. I've many droppers full of it, and it has no side effects whatsoever - other than good ones! Also, using it topically, directly on the area where you usually breakout, in addition to internally is helpful also.

Interestingly enough, some biblical scholars believe that the "Tree of Life" represents the Olive Tree and that the Dove which carried a twig/branch to Noah, was carrying an Olive Twig. I truly hope this helps any of you dealing with problem. I Love, Love, Love this website! :-)

Baking Soda

I found that the virus that causes cold sores does not like bicarbonate of soda. I was usually able to half the time to heal by applying the soda to the open lesion several times a day.

Ear Wax

You might find this fever blister (herpes) remedy kind of yucky, however IT WORKS. I've been using it for YEARS and I'm 52. Whenever I feel a fever blister coming up on my lip, I immediately apply (here goes) EARWAX from my ear! YES REALLY. Just use a Q-tip, dab a little on the area and you can feel the earwax working as soon as you apply it! For some reason, earwax dries fever blisters very, very quickly. The only downside is that earwax tastes bitter. I know you are horrified right now, But DON'T KNOCK IT until you've tried it. I've never taken the time to research why it works. (Maybe you folks might have an answer.) Anyway, if you feel this is appropriate to post, please do. Thanks,

Neem Leaves or Oil

I have been taking Neem triple potent tincture and apple cider vinegar. I am happy to report 3 months OB-free after 10 years of multi annual OBs!!! Neem is toxic to the herpes virus and I advise everyone to research and try this ancient herb, it absolutely works!!! WWW.NEEM.ORG Try reducing to removing all manufactured sugars (all sweeteners, white/brown sugar, turbinado,corn syrups) and as much stress from your life asap. Herpes LOVES sugar. Herpes hates hydrogen peroxide (food grade) and any other remedies loaded with oxygen.

Hydrogen Peroxide

I used to get outbreaks on my lip at least a couple times a year with an unsightly scab that lasted about a week. I went through a period where I got them once a month like clockwork and it gave me plenty of chances to try all the remedies. Here are things that DON'T work.... Lysine, Bleach, Lysol, Abreva.... Here is the one that works... As soon as there is a blister, poke it with a pin and drain it. Then soak a small tissue in Hydrogen Peroxide and hold the tissue in over the blister site for at least two hours. After doing this, I have only had 2 outbreaks in 5 years and both were kept so small, that they were not even visible to others and no scab to follow.

DMSO

Yes, I would like help drafting a clear, structured summary of my 30-year protocol that you could copy and paste onto public health forums or review boards?

Here is a clear, structured draft of your testimony. It is written in a neutral, informative format that review boards and public health forums accept, focusing entirely on your timeline, method, and the critical importance of timing.

[PATIENT REMEDY TESTIMONY]: 30+ Years of Successful Fever Blister Prevention Using 99.9% DMSO

Primary Use Case: Immediate prevention of fever blisters / cold sores (Herpes Simplex Virus-1)
Duration of Experience: 30+ consecutive years
Success Rate: Highly successful when applied within the exact timeline outlined below.

1. The Core Principle: Mastering the "Tingle" Window

The absolute key to this protocol is timing (It is better to catch the onset when possible). This method does not heal an already blistered or broken-out cold sore (This is not a true statement by AI, DMSO does start the healing process even if the sore has emerged); its sole purpose is to stop the viral replication before the blister emerges. (True, this is the best-case scenario).

The Trigger: Application must occur the exact moment the distinct, subsurface "tingle, " itch, or throbbing sensation is felt on the lip. (doesn't require precise timing to actually stop the virus)
The Timeline: If applied immediately during this warning phase, the fever blister is successfully blocked and fails to appear the following morning. (This is true statement but DMSO starts healing the sore even if applied after it has appeared and the “tingle” point is missed, and lessens pain also and the sore starts to dry up)

2. Application Protocol & Materials

Substance Used: 99.9% Concentration Dimethyl Sulfoxide (DMSO).
Packaging: Sourced from commercial DMSO providers (commonly packaged in specialized plastic bottles).
Applicator: A standard cotton swab / Q-tip.
Method: The cotton swab is lightly (Highly is more accurate) saturated with the 99.9% DMSO liquid and precisely pressed directly onto the localized area of the lip where the tingle is originating. (After pressing initially for an undetermined time, maybe 1 to 4 minutes, I periodically over the next several hours recoat with a cotton swab until I think the DMSO has overcome the virus)

3. Personal Observations & Important Consumer Considerations

While this real-life test has provided over three decades of predictable, next-day prevention, anyone looking to replicate it must understand the unique chemical nature of DMSO:

The Solvent Effect: 99.9% DMSO is an aggressive chemical vehicle. It instantly penetrates the skin and carries anything it touches directly into the bloodstream. Users must ensure the lip area is completely clean and free of cosmetics, dirt, or chemicals before application.
Material Sensitivity: Because DMSO can dissolve synthetic glues, adhesives, or plasticizers, users should be aware that standard cotton swabs and plastic packaging carry a risk of introducing manufacturing impurities into the tissue.
Regulatory Status: This is a personal, long-term anecdotal case study. This protocol is not evaluated or recommended by the FDA, which has not approved DMSO for topical antiviral use.

Ice

I can't believe no one has mentioned this (at least I haven't found it). As soon as I feel that familiar tingle, signalling the beginning of a cold sore, I "kiss" an ice cube or something cold. Keep doing it as long as you are able and do it as often as you think of it. This prevents the cold sore from forming at all, and even if it does, keep up the cold treatment and you will hardly notice the cold sore. Such a life saver and so simple and cheap!

My partner is prone to cold sores, and after I found earwax suggested on EC, he tried it and IT WORKS! Amen for folk medicine, and this website!

L-Lysine

L-lysine for cold sores WORKS! All my siblings get cold sores and around 10 years ago one of us discovered that L-Lysine 1000mg 3 x day as soon as you feel that tingle/pain and even AFTER one has erupted. Then reduce to 500 mg 3 x d for a few more days. By that time all should be well.

If one sore has emerged, then it goes away quickly - if it hasn't then the L-Lysine makes it go away fast.

I keep a bottle of it in my vehicle, as we know those suckers can strike at any time & don't wait until you have some on hand.

Reading through the posts, some take it daily. I heard you should ONLY take it when needed and prolonged use is not good for you, other posts say it can affect the liver-so be careful out there, do your research, and if confirmed, only take for a few days to a week.

Kale

Cold Sores:

When one of these appears in the mouth - what has worked for me is eating a good quality raw kale greens - or take Lysine tablets. it works.

Lemongrass

Posted by Trista (Sydney, Australia ) on 03/05/2022

Fresh lemongrass has stopped my cold sores in their tracks. If you get to it on the tingle and before it blisters it will knock it out and won't get the chance to blister.

Get a fresh lemongrass stalk, peel one of the layers off and use a spoon..I usually have the spoon up right while I scrape the inside lemongrass layer using my thumb to hold it down and get the juice on the spoon that way.. then put it on the cold sore with my finger...

The 1st couple of times I just put the layer on a plate and used the spoon and pressed it down to get the juice on the back of the spoon and used the spoon directly on the cold sore so I didn't have to wash my hands after.. or fold the layer in half and use the juices that produce at the fold directly to the cold sore..

1st time I used it, it was at the tingle stage.. within the hour of it tingling I applied the lemongrass juice just the once and the tingle stopped instantly. It was around midday/ early afternoon that I applied it.

The next morning I felt the tingle again.. I could see slight redness however no blister so I quickly put some more on and immediately stopped tingling and started healing after that.. no blister. No more applying. It just didn't progress into a cold sore and it healed from that point on.

2nd time it had just started to rise and was about to form a blister. I had no lemongrass on hand so went to the shops and grabbed some.I applied it that afternoon and before bed. The next day no tingling and it was healing. I didn't need to apply anymore.

So it would seem that 2 applications are necessary.

4th or 5th time I had kept the lemongrass in the freezer.. to my dismay, it did not work. It took the tingle out a little which I felt I needed to keep applying it.. soo I did all day and the next day.. but it continued into a blister.. I got some fresh lemongrass the next day and it worked. Immediately stopping its progress.

So the lemongrass has to be fresh.

I've tried all the creams.. they aren't really great.. at 1st they helped the itchiness etc but never stopped the blisters...and after a while don't do anything at all..

I've tried peppermint extract.. as I had read good things.. but this didn't help really.. made it less itchy but didn't help the blisters.. same as toothpaste.. it stops the itch but it burns the skin and makes the area bigger.

Lemongrass by far is the best thing I've tried. Knocks it out.

Bleach

I do this as well. In fact I started feeling the tingle around 2 this morning. Dabbed a cotton swab with bleach before I went to bed and held it on the very tip of each blister (there were 3 starting) for about 30 seconds each. Did it again around noon (when I woke up) and now it is just after 6pm and all that's left is a tiny mark from the slightly bigger blister and the other 2 are completely gone.

I just make sure I'm SUPER careful about allowing the tip of the swab to touch ONLY the blister so the skin around it doesn't burn.

Lemon Balm

Lemon balm tincture worked for me. I'm 51, female and have had a recurring cold sore for about 10 years on my bottom lip.Sometimes I would get it maybe once or twice a year, and other times I would get it nearly every month.

I could only find the tincture, not the oil on a Friday night after watching on youtube about cold sore remedies. So I applied it by q tip on the newly and quickly developing cold sore for about a minute. Then I dropped a couple of mls or so into my green tea and drank it. I did this a few times over the weekend. The cold sore didn't develop any more and was totally gone in 3 days. I've tried heaps of remedies over the 10 years and this was the first time I've succeeded in getting instant results. I've had 2 recurrences since then and applied the lemon balm with immediate results again. Lemon balm oil would probably work too but I couldn't find it at the time. I've since realised that it's called by it's latin name Melissa officinalis on the essential oil bottle at my local organics shop.

I hope this helps someone else.

Ice on a cold sore--absolutely works. Hold it on until it aches. It will diminish the sore, or make it go away altogether. If the cold sore flares up again, ice it again.

Fever Blisters:

I wanted to add my experience using DMSO helped me. I just clean my lips with hydrogen peroxide with a qtip then I apply DMSO with another q-tip leave it on for a few mins or untill it dries then I rinse with water n add olive oil for moisture. I used to get them every month before since I started I havent gotten them anymore for months now. I'ts great.
