So I have tried many many things for the past three years to deal with embarrassing cold sores and surprisingly most are listed on this site and most do in fact work to some degree or another.

For instance, on a 1-10 scale with 10 being awesome: 1. ACV applied (3) 2. Acetone applied (6) 3. Ice applied (4) 4. L-Lysine taken (5) 5. Earwax applied (7) (hey when your desperate you'll try anything! ) 6. Zinc taken (3) 7. Lemon Balm (9)!!! 8. Organic Oregano Oil applied (7) (if the right strength is applied enough) 9. Tea Tree Oil applied (5) 10. Tea bag applied (2)

If you are reading this and looking for some relief then you have probably read a ton of others too, and what you should have noticed by now is that no one thing by itself is probably going to be a silver bullet. What I have found that works for me is: Lemon Balm oil (1oz bottle with dropper) apply to q-tip and hold that on the spot for 1-5 minutes at a time, do as often as needed through out the day. If done at the very first sign this is amazing with helping slow everything down. Then up the L-lysine to 3000mg (1000 each dose). Drink plenty of water - the body needs it! Eat healthy (I even fasted for a day once and it helped).

Take a zinc supplement and make sure your getting all the vitamins and minerals your body needs and plenty of rest. I also have tried BHT and I think it helps....but that's not natural and is very controversial in this kind of community.

Mistakes: too strong of OOO - I burned my lip and it took as long to heal as it would have the cold sore (but it worked the sores were gone the next day)! . Topical Zinc Sulfate - also burns. TTO applied too often - burns and stops working after a while. Really in most mistakes it comes down to overdoing it. I know we all want it gone yesterday but NOTHING is going to do that so have a little patience. Best of luck!

The herb Lemon Balm There is actually some research to support its effectiveness against the herpes virus. Take it when you first start to feel the pain. 2 or three capsules, Then back off and use 1 maybe 3 times a day. Zinc oxide ointment on the sores at night. I use coconut oil in cooking. May help.

You are spot on. Lemon Balm is my main weapon now (liquid form with dropper). I also take coconut oil (1000-5000mg) depending on how I feel, and having enough Zinc is also key. I rotate in Echinacea with Goldenseal every so often and always take L-Lysine. Thanks for sharing!

I have tried a number of remedies for cold sores with no success: ice, apple cider vinegar, lysine (was ok), crystal salt deoderant (only helped the blister dry up). I get cold sores every couple of months so was very keen to find a good cure. I recently attended a medicinal herb workshop and was told to try lemon balm. I happen to grow it in my garden so I made a tea of it and have been drinking it 3 times per day. I found that within a day the cold sore I had went down and all pain subsided. It is now healing well. Additionally I have put some goldenseal ointment onto the healing sore and that is also clearing up a lot faster than normal. The teacher at the herb workshop said her husband use to get regular cold sores and he now drinks lemon balm tea often. He has not had a cold sore in years.

Are you on any blood pressure med? There was a certain bp med my husband was on and it caused him to get cold sores. (I'm a nurse and that really doesn't make sense, but... ) He started taking Lysine to stop the cold sores and it worked. A few years went by and he got a new doctor who wanted him to use a newer, different bp med. My husband, being my husband, ran out of Lysine and never bothered to replace it. When I asked him about it, he told me he hadn't taken Lysine in a long time and really felt it was the old brand of bp med that had been causing the problem.

Angela, do you know if this would help for canker sores (inside the mouth) 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 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.


Licorice and Peppermint Root Extract

While I have yet to find any success curing my cold sores, I have found one particular thing which prevents them.

It seems that certain remedies work well for one type of person but not the other, in the past I have tried Lysine, over the counter meds (they worked for a while), ice cubes, finger nail polish remover.... Ummm just about everything. Non of those worked well for me, for the past three years I have been using a licorice/peppermint root extract in gelled form. When I feel a cold sore coming on and I use this (I apply it every several hours at the onset) it never comes, I use this if I know I might get a cold sore (I'm sick or something), and I use this on my son. Unfortunetly, he doesn't know when a cold sore is coming on so it is usually already surfaced by the time I see it. However, when I put it on him the cold sore goes away very quickly and stops growing. I have noticed that over the years my cold sores are getting farther apart. I use to get them about 8 times a year and now its about 3-4.

If nothing else has worked for you, this might be the one- because nothing ever worked for me!

For those of you that have suggested a liquid bandage product - and for those of you who have wondered why on earth it might work....

I checked the ingredients this morning. In this order, it contains acetone(! ), alcohol(! ), isobutane-propane (propellant), oil of cloves(! ), pyroxylin solution. Three of its "inactive" ingredients are remedies that have been suggested in the comments as fixes, and one of them -- acetone -- has been recommended over and over.

If you haven't had a chance to check out the research someone posted earlier, there actually is bonafide medical research (by people with standard credentials) that shows that acetone does inhibit the reproduction of the virus by 90% - 97%. And it is a naturally occuring substance in the body, although NOT to be taken internally, without danger of running into things like Bell's Palsy, as someone else has mentioned. (i.e. , don't put it inside your mouth under any circumstances -- as they say, for external use only! )

Thanks for all the suggestions, everyone. I'm trying them all (well, almost all). Humongous case, worst I've ever had. Moved from my lips to around my mouth, covering one jaw and under my neck. It's still spreading, but no where near as fast as it was. And no longer as completely uncomfortable and distracting as it was. Fortunately, I'm not letting it stop me. If other people are offended by looking at my disfigurement, that's their problem. I'm not going to miss work because I look funny.

Good luck, everyone!

I used liquid bandaid and though peroxide works very well, the liquid bandaid helped the sore from getting any air. I personally feel that the liquid bandaid worked faster than the HP.

I couldn't believe it till I tried it. I started drinking 20 drops twice a day religiously plus DMSO cream to previously affected areas five times a day for five days out of each month. I haven't seen not even a scar since. It's amazing how much this site helped because I thought there was no cure for this!!!! Well, If it's not cured it certainly is really really diminished.

Local Concentrated Heat (LCH)

I have used LCH machines for mosquito bites with great success. The ones with ceramic plates that can reach 51C. If one searches in the internet, there are many good comments for these machines from buyers. There is also this research:

https://pubmed.ncbi.nlm.nih.gov/24231728/

Use these machines at least three times a day from the first signs of a cold sore. You can use them repeatedly but with 2 minutes intervals at least in order not to get burned. No more than 5 uses per hour. The burning sensation is for about 3-6 seconds.

Lugol's Iodine, Coconut Oil for COVID and Oral Herpes

My sister, her husband and her four kids got Corona, even her newborn got infected severely.

On my recommendation (I am not a doctor, only an old reader of Earth clinic ) she and her husband took 5 drops of Lugols Iodine 5% three times a day. In addition to Lugols Iodine they took 1,2 tablespoons of Coconut oil two times a day. She gave Iodine and coconut oil to her kids too.Kids' dose is 3 drops of Lugols Iodine thrice and 1 or 2 TB of Coconut oil.

Besides these remedies, they took panadol and vitamin C from the local doctor's advice. Adults gargled with warm salt water and iodine water too.

With the grace of God Almighty they were all relieved and Cured just in two days. After two weeks they tested negative for Covid 19. I personally use this protocol for the oral herpes, I start it seeing the first sign of tingling on my lips, always works, want to share on Herpes cures page too.

In the Past I used to get cold sores on my lips almost every month. That was so annoying and painful. Three years ago I visited my homeland and being a guest and having parties with friends and relatives ate spicy dishes with ketchup and drank so much soft drinks that at the end of my journey when next night I had a flight for Germany I felt tingling on my lips, alarming cold sore is coming.I wanted urgent relief and want to stop it on its way, because I did not want to travel in constant pain and looking horible with swollen lips.I had Lugols Iodine 5% and coconut oil at hand.

In desperation I took 5 drops of Lugols Iodine and 1 tablespoon of coconut oil after 4 hours took another dose of 5 drops of Iodine and coconut oil. After 2 hours I felt a little relief in tingling on lips and cold sore stopped getting bigger.After 2 hours before depature of my flight I took third time 5 drops of Lugol's Iodine and no more coconut oil.In aeroplane I was sitting relaxed and happy with my family, no more tingling and pain.So quick relief I had never in my life.When I reached home the little sore had turned brown.So in the last three years I did not have a single episod of herpes because at the first sign of herpes I start this protocol, always works like a charm.Now I can eat spicy and sour dishes, ketchup, nuts and soft drinks in moderation without any fear of getting herpes.

I take daily 4 drops of Iodine for general health too.

I think same protocol will work for gentials Herpes too.

I didn't have any acetone to use this time and I really didn't like using it at all so I used 4,000 mg of Lysine spread out through the day, 3,000 mg of Vit C spread out through the day, and I dabbed coconut oil on the sore twice.

In ONE DAY, it was dried up with barely a tiny scab left over and this thing had seven different bubbles and felt like my lip was really ready to swell up.

I will stick with remedy FOREVER.

I heard magnesium oil spray does the trick But I have not had one to try it. When I have I have used aloe, aloe by cutting a square off and placing on lip sit 15 minutes and it will Usually stick for the rest of the day until it's gone. It will take me three days with aloe. Also lysine. I was drinking a lot of black tea and I heard black tea blocks lysine in our bodies and so I would get them more often or more easily prone to getting them.

A drop of liquid magnesium chloride (aka magnesium oil) on the end of a Q-Tip, will kill a cold sore immediately.
