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!
Oregano Oil

Oil of oregano heals fever blisters within days. I actually put the oil in the wound itself and then take 300 mg twice daily.
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.
Ear Wax

Ear wax 100% works and I'm so glad I found this remedy. The key is to get to it early and it will stop it from every getting visible. But even if you miss the early stages and wake up with one, ear wax still drastically cuts down how long its around. I find, now that I know this, the max a cold sore will be around for me is 48-72 hours and usually they aren't noticeable at all. The only unfortunate thing with this remedy is you're likely to not have/produce enough ear wax to apply ear wax multiple times.
L-Lysine and Vitamin C

I came up with the tingling feeling of a cold sore. There it was. on my upper lip. I took 4 grams Lysine per day + natural vitamin C 4000 mg per day and put some coconut oil on the blister. It stopped growing and tingling immediately and the blister began drying quickly. Now it is the 3rd day and only a wound remained.
Acetone

Acetone is not the safest chemical in the world so I would use a q tip so as to target the sore better rather than a cotton ball.

Ketchup

I usually get the big cold sores that make your lip look like a balloon. It sucks. I was eating spaghetti and noticed the sauce made my lip fill better. Did a search about tomato sauce and herpes to see if there was others who tried or used it. Came across a video that said to use ketchup. It was a boring video but decided to try it...Ole family recipe or something. Anyways grabbed some ketchup and put it on my lips. Guess I know what lipstick feels like. I don't know. I put a lot of ketchup on and just started watching a movie. It tingled a little, more uncomfortable I guess. But I left it on and after about 44 minutes I could feel a cluster in the back of my jaw get zapped. Not really sure how else to explain it. Provided relied though. Provided relief for the swollen lip too. Felt like it was working and decided to put a fresh batch and leave it on all night.
Woke up the next morning and it wasn't swollen anymore. Already formed scabs and started healing. Few days later my lip was back to normal. For the healing, I put Abreva on. I typically get blisters from the sun. Haven't had any in a couple months. Might be my new go to as Apple Cider Vinegar sucks. Ketchup is everywhere! Won't hurt to try. Says to use it at the tingle stage to prevent them too.
Lemongrass

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.

I had not had a cold sore outbreak for it seems like years, but yesterday I chewed 1 stick of sugarfree gum and I have the biggest outbreak happening now....about 12 to 18 hours after exposure. I will definitely be more careful in the future.
Bleach
Posted by Corrina (AB) on 01/09/2022

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.
Ice

I have struggled with cold sores for 23 years now and have tried many things to ease the pain and make them go away quicker. I have also been an Earth Clinic follower for over 10 years and have never posted a comment because nothing has ever worked for me. Until today! I am still really stunned and cannot quite believe that it has worked so well. I keep checking my lip, but no, there is definitely no coldsore there. This morning I was at an appointment and I felt my lip start to swell and get really hot and sore. I was gutted because I am going away tomorrow for a few days and did not want to have to worry about a cold sore. When my appointment finished I quickly came home and felt I needed to apply ice to it. I did not know ice could help coldsores, it was not a remedy I had ever come across. I just knew I needed to ice it. So I got an ice pack and held it to my lip for at least 10-15 minutes, then when I took the pack off there was no more swelling or heat and the lump had disappeared completely. I could not believe it. I am still surprised! I keep thinking it might come back so I keep checking. I took two Lysine tablets and applied some cream I always put on just to be sure. Nothing there. No heat, no mark, no swelling. Usually by the end of day one I would have a full on throbbing, very painful blistering sore. I wish I had known about this remedy years ago. I know some remedies work for some and not others, but I highly recommend trying ice. It may just work for you like it did for me. And so easy. I only applied it once.
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.
Lemongrass

I suffered from cold sores all my life. The slightest stress or too much sun & my lips would be covered with the painful blisters. I spent a small fortune on aciclovir & medicated cold sore plasters to manage the outbreaks & noticed my lips had developed mild scarring.
I suddenly stopped getting them, after I started using a new organic lipbalm. Very rarely I might get one above or below my lipline, but never on the lips. The ingredients of the lipbalm are: organic beeswax, organic jojoba oil, lanolin, organic mungongo oil, organic lemongrass oil, organic peppermint oil, organic rosemary oil & vitamin E.
I googled the ingredients to try to identify which was the key anti-cold sore factor and found a 2003 Japanese study on the inhibitory effects of lemongrass oil on the herpes virus, effective even at very low concentrations. Eureka!
https://www.ncbi.nlm.nih.gov/pubmed/14584615
I'm going to attempt to make my own version of lemongrass oil lipbalm as it's such a relief not to have to deal with cold sore outbreaks anymore. Hope this helps someone else too.
Zinc
Posted by Canadiandave (Bc) on 01/28/2017 15 posts

I developed an unusual itchy red rash all over my mouth after visiting a certain restaurant, but I could have had a problem for a while. I developed a sore on the corner of each mouth only once in the 2 years since, but get the itching and redness almost every day. I used LED lights to be environmental, but had to switch back, because it made the problem much worse. So as you can see, I did not have an advanced or long term problem, but it was reduced greatly with zinc.
I read that many people with fatigue have a copper/zinc imbalance, and I thought I'd give it a try. It's only been 10 days, and no results yet on the fatigue, but the itching is virtually gone already!
This research also says that people with too high copper/too low zinc have viral problems, as zinc kills viruses in the body, with copper being better against bacteria.
I hope that's true. Not very exciting, but cleaning up my smile is a relief!
Acetone
Posted by Sam (Providence) on 11/18/2018
Hey! I would not recommend putting acetone on already formed scabs. It's hard... but you need to just let the scabs heal on their own. I have learned this from experience more than anything. Good luck!

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.
Alcohol

Many times I have the tingling sensation when a cold sore is coming on. I simply use rubbing alcohol on cotton swab and hold in at the spot for a few seconds or 2 minutes. The cold sore never materializes and the itching stops after a while. Even when there is a slight raise at the spot using the alcohol gets rid of it.
