Hydrogen Peroxide and Lysine
Posted by Anonymous (Kansas City, Missouri) on 02/26/2006

To cure herpes break outs, simply crush lysine tablets up into powder, mix hydrogen peroxide with the powder, stir well, apply paste to lesions, the oxygen i the peroxide sinks deep in the skin to kill the virus, and the lysine acts as a "shield" to prevent it from coming back in the same spot, heals very rapidly. In order to kill the herpes virus, u must introduce oxygen into the blood, (or onto the affected area) oxygen will rid the virus. lysine helps with the destruction of the virus as well, and also keeps it in remission. Try this, this is guaranteed to work. also do a google search on BHT, (the next cure for herpes). BHT looks to be a breakthrough next to oxygen therapy.
Baking Soda

Another excellent use for baking soda is for mouth ulcers and cold sores. Simply mix a teaspoon of baking soda with 100mls of water and use as a gargle. For cold sores use the same solution. Dab directly onto the cold sore using a cotton bud. Do this at least twice a day.
Local Concentrated Heat (LCH)

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.
Neem Leaves or Oil
Posted by GrassTwig (Geneva) on 02/15/2025

I have long been using neem oil for cold sores. It has to be used as early as possible when tingling appears. Cover the area and around the mouth with a thin layer and apply many times per day. Use a small 10ml empty essential oil bottle and fill it with neem oil and always carry it around with you.
This is the only remedy that actually prevented the cold sores from going from stage one to the other stages of the blisters. Using acyclovir, I always had to go through stages 2 to 5.
Together with neem oil, it is good to supplement with L-Lysine and reduce sugar coffee and other arginine rich food (wheat for example). When going out in the sun use lips sunscreens, as long exposure to sun is likely contributing to outbreak triggers.

A homeopathic remedy Natrum muriaticum stops a herpes outbreak if taken in the early, tingling stage.

Bingpensan for Cold Sores on the Lips
Many years ago in China, a local doctor gave me a vial of Bingpengsan (borneolum and borax), which is a white or pink powder. She told me to rinse my mouth three times a day with diluted hydrogen peroxide (4 parts water, 1 part hydrogen peroxide). After rinsing, I was to use the equivalent of a Q-tip to spread the Bingpengsan lightly on the cold sore. This must be done immediately when the cold sore just emerges.
Within a day the cold sore will dry up, but keep using the treatment. About day three, the cold sore will have turned into a scab and will fall off. I've kept the vial for more than 25 years and use it whenever I feel/see a cold sore emerge. It has never failed to eliminate the cold sore immediately. I'm not sure where or how to get this type of powder in the U.S., but my acupuncture doctor has provided to me a powdered preparation in capsules called Tianqi, which has the same effect on open wounds (like blisters, burns, scrapes, bed sores). Just take the the powder out of the capsule and sprinkle or spread it on the open sore (if it's a blister, just put the powder on it). The wound will dry up and scab over very, very quickly. I've never tried the Tianqi for cold sores, but it seems to have the same action as the Bingpengsan.
L-Lysine

It does work, just add vitamin C.
Olive Leaf Extract
Posted by Alex (Thessaloniki, Greece) on 08/10/2017

I took olive leafs and it worked greatly! Here in Greece we have many olive tree so I just cut a small branch and put it in water with sugar in order to preserve.
I didn't take olive leafs when I felt the nerve in the lip irritated but I was late and took it when the blisters started to appear. I chewed two leafs and put it over the blisters for an hour, securing it with a trauma tape, tree times per day.
After just 24 hours the crust formatted in almost all the area and fluid it produced was minimised in relation to other times. Also the tingling or itching period lasted only the time I didn't put olive leafs and one day more. I have even eaten some leafs.
I continue putting olive leafs three times per day until it is almost gone. The bitter taste in olive leafs is due to Oleuropein killing the Herpes virus.

I would let the skin rest and probably not do it more than a few times a day, especially each application is for an extended time.
Zinc
Posted by Dave Of Canada (Victoria, Bc) on 02/24/2017 15 posts
Well, it's been like a month since my last post. I have to say the zinc I take has kept working all this time. The information I read suggests that people who are addicted to chocolate are often the people with exhaustion, viral problems, anxiety, racing mind, etc. and I found today that exhaustion is reducing in me! I thought the 50mg of zinc citrate I take a day was only helping a lot with cold sores, but today I did some spring cleaning, and found that I could keep cleaning rather than taking a break every 15 minutes. I haven't noticed
any increase in energy over the past month and a half, but I seem to have energy after exertion, so I guess that's an improvement in stamina.
I also found that days when I did have chocolate gave me some small amount of that unwelcome itching and redness the next day, as I had read, but I love chocolate so! I found I have much less of a reaction with powdered chocolate than with milk chocolate.
(I was so happy that I celebrated with getting some chocolate! )
I am so glad that read of this connection with zinc/copper, that I think I might try exercising and seeing if I can raise my overall energy level.
Calamine Lotion
Posted by Molly (Tampa, Fl) on 08/05/2016

I've suffered with cold sore outbreaks all my life, and most of the treatments only make my sores worse. I think it's because gels and liquids irritate the sore rather than soothe it. Even a breeze blowing on it seems to make it worse. I had the idea once to coat my sore with calamine lotion to protect it from irritation and I was amazed at how it made my sore so much better. I have been using calamine lotion now for several years, and I have never had a full blown break out since. Now when I feel the tingling of a cold sore, I apply calamine lotion as soon as I can and it dries it up right away before it can develop into a huge sore. I have found the more pasty the lotion, the better it works. So I take a bit from the top of the bottle around the cap that is dried out some and dab it over the cold sore. It really is like a miracle cure for me. However, my sores tend to come up on the skin beside my lips rather than on the lips themselves, so I'm not sure how well the calamine would stick to your lips since they move around when you talk and eat. It is definitely worth a try though!
Hydrogen Peroxide

I'm a bit disappointed... I have herpes on my mouth for 7 years now. Found out about hydrogen peroxide and I did it I read the book and did everything 3 drops in a 8 oz glass of distilled water 3x a day until I reach 25 drops stayed a 25 drops for 4 days and went down to 3 then stopped and I went to do a blood test to see if I still have it in my system ( I haven't got the answer yet ) but on Saturday I felt a bump on my lip and guess what it was my herpes again.... its less intense then before.. but still frustrating that I still have it :( :(

Coconut Oil, Tea Tree Oil

Love the coconut oil for cold sores. So much better relief than anything I've tried. Also used tea tree oil this time soaked into a q-tip. But I think the coconut oil worked first. Love both for cold sores.
Olive Leaf Extract

I suffered from huge lip cold sores since my teen years. Normally they will last 1 week and them they will dry up on the following week. I could not step out of my house for at least 4 days!! It was really bad. I had tried several remedies, natural and prescription ones, with little success!! Now I have it. For me it worked!! I felt the outbreak, itching, inflammation, swelling of the lip. I took Olive leaf extract standardized pills in the following order, 2 as soon as felt it. then 2 more every 3 to four hours, for a total of eight per day. I did it for at least 2 to 3 days, until I felt nothing on my lips. I applied as well tea tree oil on the area, I did not diluted it. It worked!!! I did not get the blisters. Im not sure if it was the combination of the oil and the pills or just the pills. I tried the tea tree oil before without success. I hope this will help you as it help me!!

So happy with this! It took me 1 day!
Acetone

OMG!!! God bless the founder of this miracle. I AM ABSOLUTELY GRATEFUL IT WORKS. I woke up yesterday to the most disturbing painful sore on my lip. I used a warm green tea bag every 3 hours and pressed it against the cold sore for about 20 minutes. Later in the evening using a cotton swab I applied 100% pure Tea Tree Oil. (Please dilute with equal drops of water if you have sensitive skin) I searched the web for another home remedy and stumbled across this blog. To my surprise using the acetone for 5 minutes every 30 minutes dried up the remainder of the sore almost immediately. I felt the burning sensation but it was worth it. Thank you for this magical remedy.

I have been using Retin-A for wrinkles. Problem is that everytime I use it, I break out in a cold sore. EVERY. SINGLE. TIME.
I am sick of it and was driven to try the nail polish thing again so I bought some today because taking L-Lysine wasn't touching this one. My lip was so swollen it wasn't funny. Then, another started to pop out in a different after I started to use the nail polish.
I had to use it more than a couple times. I have been putting it on with a cotton bud every hour or so by dabbing it until the cotton ball dries out . I haven't just let it sit there for five minutes because I don't really want to breathe the fumes in. So I dab it, breathe, dab it, etcetera until it dries out and then I do it again a bit later when the thing tries to moisten back up.
It is working because I am diligently attacking it.
The thing is already crusting over after one day and normally it would take five days to get this stage. I will definitely keep putting the acetone on until it is all dried up and gone.
I am also taking L-Lysine, which wasn't really working that well, along with Vitamin C. I am planning to continue to do both as a daily preventative.

Thank you - Earth Clinic folks. The acetone works miracles! I awoke with that dreaded tingling feeling and tried using an 11 month old tube zovirax to no effect for the first half a day the cold sore just kept growing - and getting redder and itchier.
Then I jumped on earth clinic - and remembered the acetone trick. Thank goodness, the tingling stopped, it dried out and started to recede within 48 hours. It is taking a while to heal but is continuing to get smaller and smaller.
Chocolate is my #1 cold sore trigger. Each outbreak I have had in the past few years can be traced back to the effect of an overindulgence. Well THIS time I have learnt my lesson for sure.

Thank you so much for pointing out the chocolate - cold sore connection!!!
I do not like sweets very much, but yesterday I got these delicious chocolates, I tried one and then I just could not stop eating them last night!
This morning I woke up with a cold sore. This will teach me a lesson.
I tried the acetone before and it definitely helped me . So I am going to do it again now.
