L-Lysine
Posted by Another Mom (San Diego, CA) on 03/23/2023

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.
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.
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.
Colloidal Silver
Posted by Drew (Scotland, UK ) on 09/02/2021

Colloidal silver is the only thing I have found which a real and quick effect on cold sores. I apply it frequently when I get a flare-up.
I am not prone to cold sores, and the vast majority of the ones I have had can be traced to unwittingly ingesting the poison that is aspartame.
Thankfully, the silver goes a long way to countering it. If I'm quick enough, it can stop an outbreak entirely.
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.
Honey

My go to for outbreaks is honey. Its antimicrobial, antiinflammatory, and conditioning benefits work great at all stages of these buggers. So soothing and I rarely have the long scab stage anymore. I tried melaleuca homey this time and don't think it's any better than the organic I usually have. Take a tbls internally too!
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
Posted by G (Auckland, New Zealand) on 03/24/2018

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
Posted by Medina (England) on 03/07/2017

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.
Apple Cider Vinegar, Clay

I just experience an amazing recovery from a recurring cold sore. In the past I have used garlic and tried acetone topically, but I noticed that moisture always exacerbated the sore for example taking a shower would be terrible. This time I figured I would dry the heck out of it so I tried using a clay mask mixed with an equal amount of ACV on my developing cold sore. I did it two times a day for two days now and slept with it on my lip overnight and the cold sore completely skipped it's "exploding with pus" stage, dried up and is healing. I hope you try this, it really worked amazingly well for me.
Acetone
Posted by Annie (Providence, Ri) on 11/18/2015

Acetone worked very well for me. I get cold sores about once a year, usually in the Fall, when my lips start to chap from the cold. I didn't hear about Acetone soon enough to prevent the outbreak of my first cold sore this year - I was already on day 3 after the blisters had broken when I discovered this remedy. I started using it then - and it did speed healing greatly! In fact, it worked so well that I figured I didn't need to use it anymore, that my cold sore would be nearly gone by the next day or so, so I stopped using it. Unfortunately, when I stopped, it got worse the next day. I had to start using it again to see improvement. It made a huge difference in the speed of healing and that was with spotty/very late use!
Also - normally when I have a cold sore outbreak I get at least one or two, sometimes up to four in a row. Sure enough, I started getting not one but two more as the first began healing. I hit them with the Acetone on a cotton swab, pressing it into the newly forming bump/blisters, for at least 30 seconds, at least once every two hours for one day. By the next day - both were completely gone - they never continued forming!
A couple of days later, I started getting yet another, right next to where the first one was. I put Acetone on about every two hours or so, all day long. The next day - the swelling, bump and forming blisters are GONE! Completely! I feel confident that I will never have another cold sore again as long as I catch it in time and always have 100% pure Acetone on hand.
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!
Ear Wax

I get cold sores at least 3-4 times every year. The last couple years I do everything I can as early as possible to try and reduce the sore and get to the scab phase. I use ice, hydrogen peroxide, l-lysine tablets and oregano oil but no matter what I do it always lasts about 5 days to a week. I got a bad one two days ago, I noticed it as I was on my way to work and unfortunately couldn't do anything about it all day. By the end of the day it was a full-blown nasty, throbbing sore that spread half way across my lip! I tried all of the things that I normally do and nothing seemed to be working in the slightest because I didn't catch it fast enough. I
finally decided to try the ear wax method and within an hour of applying it, the pain started to go away and the sore reduced drastically. I applied some more a few times throughout the day yesterday, and today it's already at the scab phase. This will be the first thing I try from now on.
