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 :( :(

I used to get cold sores ALL the time. when I went gluten free I have had none . I know if I even get a tingle something has happened in my diet!


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.


Apple Cider Vinegar

ACV it is! Applied a soaked in Apple Cider Vinegar cotton ball on my sore and put a bandade over it and just left it there, reapplying the Apple Cider Vinegar every hour and within 2 hours the sore was dry....but kept the bandade on after that I applied aloe vera to keep it moist constantly to prevent a scap from forming bye bye sore! 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.

Gluten-Free Diet, L-Lysine

I have gotten cold sores for approximately 7 years. They started spreading all over my lips - but the ones that were new were not tingling like they originally did and came without warning. I was taking so much aciclovir and valciver. Then... I got exceedingly itchy blisters on my fingers, followed by unbelievable swelling in that finger. The pain is intense and the itchiness – OMG! (Apple cider vinegar helped alleviate these side effects - Thanks to you on Earth Clinic) I had a bout of this on my fingers for 4 months. I could not use my hands. I thought it was herpes whitlow. What cleared it up was when I was on a diet of only rice with fried vegetables – no flavorings or soy sauce added. The problem cleared up in about 5 days! Both my fingers and lips. Simultaneously, I had a brain fog clear up and anxiety that had been thwarting me for about 2 years. I then found out I am completely unable to eat Gluten. I guess the rash thing is a form of Dermatitis Herpetiformis (NOT HERPES! ) which is a consequence of not being able to tolerate gluten. (I still got the original and authentic Herpes cold sore that tingles - but it comes much less often as I take Lysine daily and it seems to come less often now that my body is not fighting the "poison" that I was eating previously). Before I had that authentic cold sore almost every 2 weeks. I am also unable to have most additives to food, and food that is GMO or treated with pesticides. For the last 3 months I have been strictly eating only at and home and it has stayed clear. I eat 100% organic, gluten free and no longer eat packaged food.


Licorice and Peppermint Root Extract
Posted by Jazzz (Delta Junction, Alaska, Usa) on 03/19/2013
★★★★☆

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!

My thanks for another wonderful and effective remedy from the Earth Clinic forum.

Every time I have a cold I get a runny nose. From all the wiping and irritation I develop a cold sore... In my nose!!! They are always painful and last a long time. I tried all the OTC products, they only cover up the sore and keep it moist; the exact opposite of what I should have been doing.

A few days ago, I took a q-tip and swabbed all the small blisters in my nose with acetone. I did this once an hour for 3-4 hours. The first thing I noticed was that the throbbing pain went away. I continued to apply the acetone throughout the day. Before bedtime, most blisters had dried up. I applied it once more before I went to bed. Then next day there were no more blisters.

Three days later, the skin is a bit red and needs to heal. I am using a combination of 100% aloe covered with antibiotic salve because I still have the cold and want to protect the area.

Thanks again for the great advice!


Ketogenic Diet
Posted by Cedar (Boston, Massachusetts) on 03/06/2013

I am a female who used to get herpes outbreaks one after another for two years. I was very frustrated, I tried everything from Chinese Herbs, Ayurvedic Herbs, Urotherapy, ACV, De-worming, acetone. I was following a vegetarian diet and jogged regularly. Nothing worked for me, and I would get outbreaks every two weeks, which each took two weeks to heal, so, "continuously" one after another.. I would get fever-ish, weak, depressed, get nerve pains up and down my legs that felt like shingles.. It was awful!

I decided to stop all cardio for a month and do resistance training (Jamie Eason's LiveFit trainer to be exact.. Free online program), and follow a ketogenic diet (high fat, moderate protein, low carb), and all of a sudden, no outbreaks or pains for 6 months.


L-Lysine

This is a fabulous result, and I know it will help lots of people.

I was taking vitamin C in similar doses and still got cold sores - at least once a month, for over 15 years. It was only when I started taking 1000mg of lysine powder, on an empty stomach first thing in the morning that they finally stopped. I've been doing that for 5 years - and the only time I've had one was when I went I ran out for 3 weeks. It's important that lysine is taken on an empty stomach because otherwise it is mixed with amino acids in food to make protein. It's tasteless and dissolves easily, so mixing it with water is fine.


General Feedback

Gina I want you to know that I take 35 drops of Lugol's 5% in divided doses daily.

I been taking all kinds of Iodine for the last couple of years started slowly with very little.

The info I can find is, if you overdose water starts dripping from your nose and like too much vit C you just pee it out. I'm 83 and still around. I take it for Hypothyroid and still can't get my basil temp over 97. 5 and if I paint it on in the AM it is gone by nightfall.

The same with magnesium oil I have to take lot's of it spray it right in my mouth wish I could find a refillable deoderent applyer so I could roll it on also, I have to take it otherwise I would get foot and leg cramps during the night.

As always do your own DD this is just one man's opinion.

May the Lord continue to bless THIS EC site and its supporters and Angels like Lisa etc.


Acetone
Posted by Artemisia (London, UK) on 12/02/2012

Gracie, that sounds more like shingles, a different type of herpes virus. It travels down the trigeminal nerve down the nose and across the cheek. It responds to Lysine and as you say, cheese, chocolate, nuts and red wine trigger and feed the virus. Counter this with Lysine (buy the powder from iHerb in Ca who ship to the UK for $6 per order). The ONLY way to dry them out (better even than acetone, is CAMPHOR SPIRITS OR in French l'alcool camphre). You used to be able to buy it in the UK, but now I have to get mine from the US yet again. You dab it on as soon as you get the tingle. Believe me, you will start keeping some in the larder. I use it now only once in a while as I know the signal tingle and start taking Lysine in juice. I was once told by a chief Medic in the Homeopathic Hospital, Tunbridge Wells "the herpes virus is a bitch". My friend in the US who gets shingles when run down, has had the vaccine and I believe you can now get it here.... It is with you for life I understand and I can locate exactly where mine resides; under the arachnoid around the skull on the left side which is where the blisters first appeared on my nose and cheek.... My nose is scarred but the cheeks are more resilient. Spirits of camphor.... As we know these cheap remedies are not endorsed by big pharma - too cheap and no profit margin for shareholders. We have to do the research for ourselves and take action.

Artemisia (purely coincidental that this is the latin for Wormwood! It was the name of an old horse of miine)


Alcohol
Posted by Lisa H. (Santa Barbara, Ca) on 11/18/2013

When I was in Nepal earlier this year I got a cold sore and I was staying a top a mountain, a three hour return trip to a pharmacy. I had failed to pack any zovirax, which has been successful in the past, so my friend and I went digging through our first aid kits and came up with alcohol swabs! Ah huh!!

After the first swipe, the burning started, but it was that good burning like you can feel the virus shrinking away from it as fast as it can kind of burning. It took about three days of day with the alcohol wipes every couple of hours to turn it completely around and kill it.

I have subsequently found acetone to work faster and be more effective, but if you are working with what you have available in a first aid kit - I can 400% recommend the alcohol swabs!


Aloe Vera

Apply ice and aloe vera. Keep the skin cool as soon as tingling starts. Works like a charm.


Cell Food
Posted by Nathan (Lexington, Ky) on 10/05/2012

Cell Food topically- This is my story. Scroll to the bottom if you're only interested in what worked for me.

Hey all, I've been following earth clinic for sometime now - and love it! I discovered apple cider vinegar on here and it did wonders for my quality of life as I used to have insanely dry scalp in the winter and acne. Acv did the trick for both.

Okay, onto my cold sore treatment: Abreva has worked pretty well for me the past couple of years. I'd keep it on me and when I'd feel the "tingle" use it and I hadn't had a major outbreak since I started using it - until Monday morning. I felt the tingle on Sunday night, put some Abreva in that spot and went to sleep. Woke up with a full blown cold sore... Yikes! Of course, this Saturday (tomorrow) I have a number of guests coming in town for what is annually one of the biggest social events of the year for me. Instead of panicking I came here and discovered the acetone treatment and hydrogen peroxide as well. I had hope!

So for the following 36 hours I diligently treated the monstrosity on my lip with acetone and hp. Only problem was by Tuesday night I had not one sore but three! It was the worst outbreak of my life. The acetone seemed to aggravate the infection, not to mention it smelled terrible and the hp didn't seem to go deep enough. I believe those treatments work for many of you - they just didn't for me. The nail polish remover I was using I later noticed included gelatin in the ingredients and I read elsewhere that gelatin can aggravate an outbreak -maybe that was it.

Anyway I woke up Wednesday desperate, ready to call off plans for Saturday. While obsessing over what I could do, I remembered reading that Cell Food helped cuts and burns heal fast, so I googled it to see what I could find out about it's effect on cold sores. I didn't find much, just one testimonial but it was positive. What did I have to lose? So I gave it a shot. Went to the bathroom grabbed some cellfood and put a couple of drops on my lip and it burned like hell (way worse than acetone or hp). I thought "this could be really good or really bad". 30 minutes later my lip was drying out and the swelling was going down so I put another drop on my lip. By Wednesday night the "tingle" was completely gone and all of the sores were drying up. I continued to use cell food every 3 hrs (I would also put some drops in my juice and water) and yesterday my sores started to scab over.

This is the amazing part: last night the healthy parts of my lips were starting to grow like a new fresh layer of skin I think from the cell food. Today the two smaller sores are 90% healed and the big sore I think will be 90% by morning. My lips are chapped from being so dried out, but after the sores are nearly completely gone I'll use chap stick.

I said to a friend earlier this week that it would take a miracle for my lips to heal by Saturday and I actually think they will be fine by tomorrow. I started on Cell Food Wednesday with 3 throbbing sores!

This is the first time I've shared on earth clinic. I hope this works for you as good as it did for me! Oh, yeah: I must say Thank God! Because I prayed a lot too! He answered my prayers :)

Straight Acetone is the best, and at night I use calamine lotion to aid in the drying, makes you look funny, but it works! Two to three days and gone! Completely!

Well, Well, I feel your pain but you do not have to live this way. Do not listen to the doctors, there is help out there. The problem is people do not want to change their diet. If u read my post on the "onion family" cure u would c that two people were cured passing on info to the next. I just found out that one of them had it for 7 yrs before she got cured. Upon finding out she immediately chnaged her diet, ate organic produce( only from the land and NOTHING processed). She does not use deodorant but makes her own from fresh lemons/limes. Drinks distilled water/minearl water. She takes cold pressed coconut oil daily and has been retested multiple times and the result is still negative. She has stopped taking the onion drink after her kidneys were messed up(she drank it excessively). She still maintains an extremely healthy lifestyle. Her shower has a filter and so is her tap. She uses no flour, rice etc. But this is what cured her. She also used lots of herbal stuff, no pill nor capsule.
