Tea Tree Oil
Posted by Desiree (Portland, OR) on 01/08/2009

For cold sores I apply the highest quality of pure melaleuca oil (also known as tea tree oil) on my sore as soon as I feel the tingling and often it does not erupt. This oil is penetrating and goes deep into the tissue, so bear that in mind when you decide where to put it. I would avoid too close to the eye, and I don't know if it can cross the blood brain barrier. Does anyone else? What might the effects be? I have tried everything on the market and this works every time. On an outbreak, it will take the eruption away in a day or two.

For systemic effect, I have found a concoction that takes it away for very long periods of time, usually no matter the stress level.

I make a blended green smoothie out of 1 fuji apple (peeled and cubed), 3 sticks of cubed celery, 1 1/2 C trimmed parsley (without the stalks), 1 inch of fresh ginger (cubed small, smashed with the blade of a vegetable knife and minced), 1 1/2 to 2 cups washed, destalked and cut to bite size green kale (I like the dinosaur kale best), 1 - 2 inch peeled banana, dash of cayenne pepper, 1/3 cup pure pressed unprocessed apple cider or apple juice, 1/3 cup water.

I add all this into the blender (I have a commercial blender that breaks down the cell wall of the kale which is thick and tough) and I blend it about 40 seconds until it is almost as thick as a milk shake. I drink the whole thing for breakfast.

At 50, it works better with enzymes, I think. The more raw vegetables that I eat, the more I can eat without the stomache ache I used to get when I eat vegetables. All ingredients are organic. The water is bottled spring water.

I drink this daily and have no outbreaks or tingling for about 3 months after I haven't had one. In the summer I trade the apple for a pear or a peach (yummy). This tastes great no matter which fruit you use. Should last you all morning, unless you need enzymes. Best Wishes.

I dealt with cold sore on my mouth (lips) for many years. Then I read somewhere to stay away from nuts and citrus to keep the herpes virus under control, which I have done for the past few years. I almost never ever get them anymore. Once in a great while I may eat a few nuts or citrus & if I overdo it (which I almost never do) I may get a very small sore on my lip. But, I usually don't mess with the nuts & citrus and as long as I don't, the cold sores stay under control. For me, keeping away from these two items seems to work really great. Cathy

I suffered frequently from cold sores most of my life. The embarrassment of a large outbreak on the lips is enough to want to hide away at home until the sore dimishes to just a small scab. But that's not possible when you need to work. It's even worse if, like in my job you need to interface with the public a lot.

A few years back I changed my diet by excluding or seriously restricting all wheat flour products because I was getting overweight and could hardly tie my shoe laces without needing to come up for air to finish the knot. It was hard to start with because these foods are so tasty and addictive. But as a result of the diet change I not only lost 15 kilograms but also found that I no longer suffered from cold sores or head colds either.

On the very rare occasion that I do get a cold sore now I can immediately trace it to a binge on bread, pizza, pasta or rice the previous day, and the lesion is tiny in comparison with the past. To control it I abstain from the flour products and rice and try not to lick my lips, and it goes away within days. Nuts, chocolate and citrus fruits are not a factor in my case nor are diet drinks because I don't really go for them much.

I wonder if genital herpes would respond to the same dietry restrictions.


L-Lysine

Best ways to preventing a cold sore: I used to get cold sore and at first I had no idea what they were, then the doctor started giving me a cream to put on it which I thought was useless. Then I read about Lysine, now Lysine is a life saver. I also came across this device called Virulite, which helped prevent cold sores from forming by targeting the immune system to fight it before an outbreak. So every time I get stressed from work or school, I take 6- 500mg of Lysine daily, I spread them out during the day. Also if I feel a cold sore or a burning sensation anywhere, that is where I use the machine. Hope this helps ;)

Acetone cured my cold sore! Stressing about Thanksgiving arrangements, pleasing family memebers,etc. which triggered a cold sore on my lower lip about the size of a nickel. So the day before thanksgiving I checked earthclinic and saw the acetone remedy for clod sores..I figured what the heck...I had already tried the over-the-counter remedies in the past without much luck so I applied the nail polish remover with a q-tip about four times that day then applied an anti-bacterial cream to clear up any infection. Overnight I was pleasantly surprised to see that it had reduced the cold sore to about 1/4 its original size! Flat, not sore, tingly or anything.Applied a small dab of makeup for Thanksgiving dinner and it wasn't even visible! Yea! Thanks Earthclinic!!

Acetone nail polish diminishes cold sores

You have to keep using it, though, for at least an hour or two. I'm in my 50s and have had cold sores ever since I was a little kid. I have found that if you can attack them quickly and aggressively, you can diminish them.

First, get a bottle of acetone nail polish remover and an over-the-counter strong cold sore ointment. First put the ointment on and let it sit there for a few minutes, then swab the sore with nail polish remover until the swab isn't cold anymore. Apply the ointment, and swab again. This takes two or three hours, but it's worth it. If you catch it early enough, the swelling will go down quite a bit and may be almost unnoticeable in the morning. I'm usually able to conceal it with a cover stick and a little powder the next day.

Eat flounder and you will never have an OB again. In the mean time work on finding a cure. Flounder, like cod and some other fish is loaded with lysine and the body knows the difference with it and the lysine pills. Look at my post that say "flounder" so u can prepare it. Do not settle there, while you treat, focus on getting a cure and change your diet. You do not want to live this way for the rest of your life. Also read my post on onion/garlic drink where two people got cured. The followed a strict diet, ate organic and only food from the land. Nothing processed, no meat etc.


Bitter Melon
Posted by Veronica (San Antono, Texas) on 11/20/2008

Bitter Melon has worked wonders on cold sore outbreaks. I get a tingle, take a couple of capsules and it subsides. I have tried coconut oil, but the results were not as spectacular.The few times I could not get the capsules in time (at work), I simply took them as soon as I could and the break out was lasted about a day and was not even visible- just itching and some slight burning. Bitter Melon beats all the others, hands down.


Artificial Sweetener Link to Herpes
Posted by Kat (Norman, OK) on 10/25/2008

I found this site while looking up lysine, and was shocked to read about a link between outbreaks & artificial sweeteners. I've had herpes for about 3 years now (that I know of anyway- Aug. 2005 was my first outbreak ever), and I've been outbreak-free since that first one up until about 3 months ago. I could not figure out why all of a sudden I was getting an outbreak a month but then I figured it out tonight- DIET SODA! I switched from regular coke to coke zero roughly 3 months ago & that's right when all the nerve pain & outbreaks began! God no wonder. I know for a fact I have a good immune system & I'm not under a lot of stress, so I was beginning to get scared. Just bought a new case of coke zero tonight & it's going right back to the store tomorrow. I'm going to try some of the remedies listed on the site, thanks.


Apple Cider Vinegar
Posted by Dave (Parts, Unknown) on 10/14/2008

I was originally diagnosed with GW early last March. The doctor prescribed Aldara which worked a bit but as many of you know it's very pricey. i finally thought i had it kicked only for it to return in full vengeance about a month ago. I started back up with the Aldara than stumbled upon this site.

I started the ACV treatment 3 days ago and it definitely seems to be working as the affected area is either completely raw or blackish/green in color. The warts arent raised from the skin at all and the blackish/green portion is a couple of splotches.

I have noticed that much smaller black marks have appeared on the opposite portion of my penis that the ACV has not even touched. I assume these are much smaller warts that the ACV is triggering. Is this assumption correct? If so, I guess I need to attack these too. A couple of them are on the side of the head of my penis so I'm not looking forward to my head getting even remotely raw. Any advice?

Anyways, thanks to everyone for sharing their stories and advice. This remedy definitely seems to be working and I am optimistic for the first time in a long while. Well best of luck to everyone and thanks again!

Put the apple cider heavily on a cloth and wrap it around your penis. It may smell a little funny but it will work...

I started suffering from a form of herpes called gladiatorum herpes in my face from practicing brazilian jiu jitsu with someone who had the virus. It has one of the most, or perhaps the most horrible illness I ever had. Started taking L-lysine and it helped, stopped taking anything with Aspartame, it helped, however, everyweek for the last three months I was having outbreaks every single week!! Reading and researching on the internet, I figured I had a very acidic PH in my blood so I started doing the Gracie Diet (google it), I can say after a week and a half I am for the first time in months, free of outbreaks.


Hydrogen Peroxide
Posted by Shelly (Middlebury, Vermont) on 09/22/2008

I currently have an outbreak (the second one in 2 weeks) and I used peroxide on my second one after the first day. I didn't catch it in time but I'm finding that using the peroxide only 2 times has prevented it from really blistering and scabbing over too much. I popped the blister and drained it with a tissue and then used a qtip to dab it on a few times. It seems to take out the infection and dry it up faster. I'm going to continue applying peroxide every few hours and see how it works. I think if I'd have done this quicker, it wouldn't have blistered out quite so much. But it's less sightly than it would normally be.

L-Lysine and Vitamin C

Well, I had a cold sore on right corner of my mouth for about 6 months now, it just kept scabbing, then falling off, then scabbing, then falling off, i tried everything, so far its been 1 week from taking l-lysine and vitamin c daily, about 10g a day, and so far, nothing, i still have the cold sore, my doctor gave me acyclovir, but yet it didn't do a thing. Anyone have any suggestions, im really suffering from those terrible cold sore i had for about 6 months. HELP!

L-Lysine

This site is the best thing I have found! I was in complete depression after a wrestling sparring partner infected me with Herpes Gladiatorum (HSV1) on my neck and face. It was a nightmare and this site was my salvation. I have tried L-Lysine and it worked perfectly, even if I feel a new OB I just start taking 3K Mg daily it has been under control. In addition I use Hydrogen Peroxide and smash a L-Lysine Pill and put in my face.

The only problem right now is that even the sores are closed, the red marks/spots on my face and neck are still there even after more than two months of being diagnosed with HSV1! Sometimes it gets irritated when I shave, is this normal?? Can someone please recommend me what to do?

L-Lysine
Posted by D (Orlando, Fl) on 10/14/2012
★☆☆☆☆

For Herpes Gladitorum avoid heat/getting overheated/sun. Apply cold (wash face and neck in cold or tepid water, or at least end your washing with cold to close pores and reduce inflammation). Bathe in tepid or cool water ending with a cold splash/ice on problem areas, apply cooling aloe vera/ice to tingling areas, stay cool and hydrated (without getting chilled enough to catch a cold) and pull hot collared shirts away from the neck. Keeping the skin cool works like a charm for me. I have not had a break out for months with the 'cold treatment'. Years ago used to break out constantly. Lysine was not effective for me. Best wishes! :)

Check the other 'Ice' remedies on your website for Herpes Outbreaks. Many others have experienced good results with ice/cool water. Other websites also mention avoiding heat/sun.

Astringent Toner

I got Cold Sore while camping this summer. I have no clue how I got it, could be from sharing cups or from the grass. I felt the tingle on my upper lip while returning home. I went to see the doctor immediately. The doctor recommended acyclovoir cream, but I don't find it very effective. However, the nurse told me to wet a cotton ball with alcohol and rub around the lips for 5 minutes. I didn't have alcohol at home by then, so I used my toner instead, because there are alcohol in my toner. I felt comfortable using toner since I used then after washing my face everyday anyways. I wet the cotton part of bandage with Astringent Toner and stick the bandage on the bump. I repeated this about 3-4 times daily for two days, and my cold sore disappeared! The toner I used is called Garnier Pure - Astringent Toner - Tighten Pores. You can get it almost anywhere.

Hi Juliana, For future reference for your herpes simplex (cold sore), when you first notice that tingling feeling that heralds a budding cold sore, start taking L-lysine 2 grams (200 mgms) 4 times a day and you will find it drying up by the next day. I have found L-lysine effective against all viruses that I have tried it for to date.

I too have had coldsores all my life and am 50 yrs old now. I had a sore in the inside of my nose for 3 days , first I dapped peroxide.3% on the outside and the inside where I felt it sore and there was no change into the 3rd day. On the 3rd day I inhaled 3 or 4 puffs of a mix of half water and half .3% peroxide cheap Wal -Mart kind, from a 2 oz spray bottle that you can buy at Wal Mart for .50 in the toothpaste aisle where they have travel size items, and 2 hours later all the nose pain was GONE and no longer had a sore in my nose , it vanished. I also used Apple cider Vinegar the off brand at Wal- Mart GV . It's such a great value too, only $2.99 and I take the pinch or 1/4th tsp of Baking Soda and 2 TBLS of APPLE CIDER VINEGAR in 4 oz of COLD WATER and it has lowered my heartrate from 117 to 72.This has also lowered my BLOOD PRESSURE from to 112/60 I feel full of energy and I do this before I eat first thing in the morning and last thing at night. I sometimes take it at NOON for a pick me up. I no longer have acid reflux/ GERD. I sleep and breathe better as I have sleep apnea.

Aloe Vera

I have gotten cold sores since I was little. And I am 22 now and i still get them. My docter use to give me this paste for them however it just made them look worse and never helped. Last summer I got cold sores probably about once every 2 weeks. As soon as one was gone another one would come in its place. I have bought everything you can buy at walgreens. None of it works, esp. Abreva the stuff just flat out does not work. I went on the internet one day and found that Aloe Vera, if you put it on the cold sore as soon as it starts it stunts the cold sore and it never gets any bigger. I also use L-Lysine tablets, about 4,000 or more mgs a day if I go to the beach while I don't have a cold sore, I will still take about two or so tablets. Also my docter gave me valtrex which does work well but only if you catch the cold sore right as it is starting to form, which is hard to do since I am not always at home when they start. Carring supplies in your purse is helpful though, I know it's a pain but when you get cold sores you gotta do what you gotta do. Last night I was at work and felt one forming on my lip. It never got any bigger and I thought it wasn't going to but than another one started to form on my lip also. I ran home and put aloe on it but I think i was too late. I am trying Apple Cider Vineger right now and so far it seems to be working so I think this will go in my list for remedies, lol. Thank you!

Amanda, from Miami, Increase that l-lysine to 2 grams (2000 mgms) 4 x a day and see if it doesn't work. It always works for me at that dosage. You might also consider avoiding high arginine foods, like peanuts.

On Monday I woke up and felt a tingling feeling in and around my nose. I immediately jumped up and cleaned my face. After washing I put novitra and abreva around the area that was tingling. This method use to work for me however it seems like with any remedy that works my system eventually become immune to the concoction or remedy and I have to find something else. Well that is exactly what happened to me this time around. I ended up with a full blown cold sore, starting in one nostril and traveling around to the other one with a cluster all on the bridge of my nose ending on the very brim of my right nostril. Very big and very embarrassing! Needless to say there went my entire week. I took off two days of work and it ruined my weekend. Just when I thought the worst was over, I was going to bed on Saturday and prepared to go through my nightly routine of washing my face etc, and low and behold there was a small tingling feeling on my upper lip. I'm screaming to myself this can't be happening. I can't afford to take off anymore work and expect to have a job when I come back but I can't endure another week of having an embarrassing cold sore at work. I put some Abreva and novitra on it and when I went back approximately 5 minutes later, it appeared to be forming a cluster. I immediately jump on line to see if I can find any type of alternative treatment and I came across this website. After reading all the comment I realized it was extremely late and I had to work with what I had. So I immediately went to work. I ran to the sink and dabbed a Q-tip in Acetone nail polish remover. I left it on the cluster for about 2-3 minutes. I then grabbed an ice cube from the freezer and compressed it against the sore blister until it had completely melted. I then dipped another Q-tip into the nail polish remover and left it on for 2-3 minutes. I put some more Abreva and Novitra on it and went to bed. When I woke up the thing was completely gone. Just to be sure I repeated all of these steps again and plane to do it again before I go to bed. But so far so good. I just wanted thank everyone for posting their remedies. If they hadn't, I'd probably be out of a job right now.

YEP!!! This seems to be a miracle solution for herpes, both oral and genital. I get both but if I take a cotton swab and dip it in acetone and hold it on the sores for several seconds (or as long as I can) they go away super fast. I keep putting the acetone on the sores throughout the day to dry them up and both oral and genital last only a few days at the most!! My friend's boyfriend tried the acetone on his genital herpes on his last breakout and they never became sores and disappeared in two days. Outbreaks don't seem to be as often either. I also take L-Lysine too but its the acetone that really does that trick.


Acetone
Posted by V (Thousand Oaks, CA) on 04/24/2009

Can you put the acetone/polish remover on the sore if you've already had it for about 5 days? Or do you have to do it when you get the first tingle? I have a sore on my lip for about 5 days that won't go away but it's already blistered. I've been putting ACV on it but it's not working. I also put another over the counter med on it, but it's not helping either. I am worried that with the stage it's at now, that putting the polish remover on it will damage my lip and make it bleed or scar... plus, we are going on a cruise in 2 days! Help!


Acetone
Posted by Suzy (Houston, Tx) on 03/17/2011

As far as the warning in reference to Acetone mentioned below, getting cancer is the least of my worries. It would seem that there are several things out there that cause cancer these days!!! As far as Acetone coming in contact with your skin, it does the same when you use it to remove nail polish! So what's the difference? We come in contact with cleaning solutions, dyes, pollution everyday. I personally do not worry about that, but rather have faith over the situation and I am thankful people have discovered and shared this remedy with others. I am more concerned with consuming artificial sweeteners than applying a dab of nail polish (remover) on my skin which is already doing something due to a *virus (Herpes)! * It would seem that treating the virus (cold sore) is the main thing as it has already formed or is about too. It's like treating a mole; the treatment would first interact or come into contact with the mole before it gets to the layer of your skin. That layer of skin is already going through something, and I have been through many trial periods using many different products and I have to say that CLEAR NAIL POLISH and ACETONE combined worked best for me! Sometimes you don't get the tingling feeling; you just start to see it coming. So as soon as I see or felt it, I washed the area with antibacterial soap, dabbed some *astringent* (which works wonderfully as well because it dries it out! ), the painted over the area with clear nail polish. I left it on overnight. The next morning I removed the clear nail polish with nail polish remover. It freaked me out at first because I thought maybe I burned my skin as I was removing the clear layer, but in reality it dried the blister out completely and prevented it from growing! So I didn't have to apply nail polish remover repeatedly like many others have suggested. I suppose if you are in a situation where you are not home, applying clear nail polish does dry up and is noticeable so perhaps continuously applying remover throughout the day until you are alone might be your solution. I also use the Lysine cream, but it doesn't always work for me. My friend says as soon as she feels the tingling she applies the Lysine cream and it goes away. That isn't 'always' the case for me, but I know it does work at times. The main thing is to DRY OUT the cold sore blister until it scabs or goes away! AVOID creams (except lysine for some), Peanuts, caffeine, cigarette (smoke! ), AND SUGAR!!! YES, it is correct that sugar (including chocolate) can cause a breakout. I was going through a period where I was craving and eating alot of sugar/sweets which I normally don't do, and I was getting blisters back to back. So I had to cut that out. Also I have noticed that tanning beds can trigger a breakout! If you must go like me, clean the pillow and bed with a disinfectant before lying down. Avoid putting lotion on your face and avoid higher level tanning beds with harsh face tanners. Better to just stick with the "level 1. " I also buy this realllly thick chapstick and cover my nose and once affected areas with it to avoid blisters. Then when I get out, I wipe my face with sanitizer. Hand sanitizer is another thing that helps dry out cold sores. Taking vitamins and supplements such as L-Lysine, Selenium, Milk Thistle, Grape Seed (Resveratrol), Echinacea, Honey (contains anti-viral properties), Coconut Oil, etc. Also helps prevent cold sores. Anything containing (bio)flavanoids or things which help your nervous system, (maintain) cell growth, or contain anti-viral agents (since cold sores are apparently caused by the Herpes "virus") I have learned are very beneficial. Exercise is important too, as a stress reliever, it helps calm your nerves and prevent cold sores. I eat a 1-2 spoons full of honey a day and it appears to be working for me, along with exercise, vitamins, and cut out sugar. They say to buy local honey, as it helps ur immune system build a tolerance against the things in your local area (pollen, etc. ). So you could check online for local honey in your area.

With this being said, everyone is different and it took some experimentation, trial periods, and research in order for me to find what works best with my body. I have read that some have gotten chemical burns (inside mouth). I do not recommend putting anything in your mouth except vitamins, garlic, honey, or coconut oil. I think perhaps even cayenne pepper may work for internal sores which I do not and have not ever had. Although cayenne pepper does treat strep throat I have learned, so it's worth a try! Also, if you have sensitive skin, then try not to apply too much of anything to prevent burn.
