I used Apple Cider Vinegar on a fever blister and it dried it up immediately.

Another thumbs up for ACV - started to feel the tingle of fever blister and applied ACV on a cotton pad. Did this for 5 or 10 minutes a twice a day for two days. While there was a small, unnoticable eruption, there was nothing like the usual cycle of blistering and then 5-7 recovery/drying out.

Hi- I love your website!

I have a question regarding the use of apple cider vinegar. Sadly, I also suffer from cold sores, which are brought on by (usually), stress and coffee. To combat them, I try to maintain an alkaline system (i.e. , no acidic foods or drinks), which are known triggers for cold sores.

My question is if you know of any correlation between consuming ACV and the occurance of cold sores. I have been practicing an acid-free diet for a while, with success, and fear the ACV will disrupt this.

Thanks again!

Hi re aple cider vinegar and cold sores.. If you feel one starting to bubble up, just dab some ACV on it. It then just collapses.. somehow the vinegar goes in and kills the virus.

ACV is actually alkalizing.

If you dab ACV on a cold sore it immediatley starts shrinking to nothing.

On this past Monday I started to have that "tingling" feeling on my lip meaning the beginning of a cold sore breakout. By mid afternoon I was right, a huge blister in the corner of my mouth ouch!!...after reading the numerous reviews on ACV as a cold sore remedy, I decided to give it a try. On this past Tuesday went to the store an got the ACV and put some on a cotton ball. Without a moments notice the cold sore started to burn like someone had threw perm on my face!!!!...but after a few moments the burning sensation went away. About an hour later the cold sore had reduced in size. I did the same thing again before I went to bed. When I woke up the next morning the cold sore had reduced in size about 1/2 inch and had began to crack as if it was drying out already!!!!....YAY!! I thought, But to my dismay there was yet another cold sore peeking its ugly head out from beneath my lower lip. After having success with the other sore, I kept reapplying the ACV with a cotton ball 4-5 times a day for both sores for approximately 3 days. Today is Friday and I am glad to say that both sores are gone!!!!! more ooze and pus filled of right now they are in the healing process, so they are scabbing over. Thanks Everyone and Earth Clinic for your wonderful tips on how to combat such an embarrassing condition!!!!..I will defintely be ready with the ACV when the next one comes!!!!!!

I have suffered with 6 or 7 cold sore outbreaks within one year, and this remedy is the ONLY thing that has made my sores disappear so quickly! I usually use popular over the counter topical meds (like Abreva)and take acyclovir (aka Valtrex). It's hard to tell how much those really shorten the duration of an episode. But with this remedy, it's very clear that the "life" of my sores has been shortened. I broke out 2 days ago, began applying ACV with a Q-tip to the sores. First time it helped the sores to burst and begin the healing process. Since then I've been applying several times a day, followed by a Q-tip with organic tea tree oil to help soothe the burning and dry them out. My episodes usually last at LEAST a week, but at the rate these sores are healing it's looking like it'll be closer to 3-4 days. What a difference! I highly reccomend this remedy.

From my experience besides eating right and taking lysine, zinc, vitamin C and any other immune booster vitamin you choose; A natural product from is the only product I've tried that works immediately. Everything else takes awhile to reduce and go away.

Reaction to ACV?

I applied apple cider vinegar on a cold sore that was on the left side my botton lip (almost on the inner part). I did this at least every hour for a few days. I would hold it there for at least a minute each time. No reaction at all.

Then I stared to get a bump on the right side of my lower lip, but inside (on the inner part). I don't know if it's a canker sore or cold sore (I know you get canker sores in your mouth but I don't know HOW far in they have to be to not consider it a cold sore) but I put acv on it. There was also a small cut in that area from picking off dry skin. Well I applied the acv less than 10 times throughout the course of a day and that area of my lip swelled up twice it size. I also felt some pretty intense tingling. I stopped for a day and took an allergy pill and it went down. Just to see what would happen I tried applying some acv tonight and it has swelled up again.

So I put acv on the first sore MANY times and nothing happened. But when I put it on the second one it reacted? Why?

I had the exact same thing happen to me. I used it on a cold sore on my lip and a canker sore. When I used it on the canker sore, it made my lip swell really big. It did nothing for my cold sore either. What can be used to make a canker sore heal quickly and go away even more quickly?

I hadn't had and outbreak for years until I started messing with my PH with ACV. I'm not saying it is the cause, but it certainly didn't help. For dinner the night before I had shrimp, crawdads, fried catflish and cajun fries with Sierra Mist. That might have sucked out all my bicarbonate reserves.

Normally ACV alkanizes but the day the outbreak started and two days after, neither ACV or baking soda with water could get my PH to go above 5. I tried dabbing ACV on a developing sore and it didn't do a thing.

Catfish, cajun fries and crawdads? You eat like my husband and he has a cold sore tonight that erupted into a facial infection of sorts. Not a good diet. Eat a salad!!! Alkaline diet!!!

Found your site while searching for natural wart remedies and read up on all the things that Apple Cider Vinegar is supposed to help. My husband suffers from cold sores (herpes) thankfully, infrequently. But he was getting a really large one and tried the ACV on it and it really worked. Soak a cotton ball with ACV and place on the area as soon as you feel tingling. Do this as often as possible for the first 24 hrs and it skips the whole burning and breakout period. The sore went right to crusting over and healing in about 4 days. We had to write in because your site helped him so much! thank you...will respond to the wart ACV remedy too because that works too!

Cold Sores: This site has been amazing & I have loved it! I hate taking medication for anything, so I try all of these natural remedies first. And I have had some Down Falls. But more good then bad. Everyone is different so not everything will work for everyone. I noticed I had a virus of some sort and noticed my lips were tingling and sore and I had many blisters forming quickly. I did not have my usual cold sore medication and I hate fever blisters so I came on here and read about the Apple Cider Vinegar Cure. I am not going to put fingernail polish remover on my lips because of the toxins in it, so I tried the ACV and it burned but not too bad. I did this throughout the day and by nighttime I could see they were drying up & looked better. Here it is the next morning. Not completely gone, but less noticeable no tingling, no pain, they are almost completely dried up. They are not hurting like they were yesterday. Also try taking Valtrex, you have to get a prescription from your doctor but it works. It boost your immune system. But I was amazed that this Apple Cider Vinegar worked so quickly! I am going to keep doing it today, and I know they will not come out if I keep it soaked down with the natural Apple Cider Vinegar. Natural all the way!

Apple Cider Vinegar will stop the progress of herpes. I have an occasional occurrence on my leg. Simply soak a small cotton ball with ACV and cover with a bandaid or tape. Change throughout the day and keep on over night. Amazingly, within a day, you will see you are winning the war!!! I also succeeded in removing a large wart from my finger.

I've been getting cold sores occasionally for 12 years and have tried every over the counter topical treatment there is, but NOTHING worked like Apple Cider Vinegar did.(I actually find that most of those oily/waxy treatments make my sores worse.) I take a L-Lysine supplement pill every day of my life which I feel helps keep the breakouts down to a minimum, but occasionally sun exposure etc. will bring on a sore and I was desperate for a treatment that finally worked! I was skeptical of home remedies especially when I read that people were applying acetone to their faces, but 2 days ago I had a cold sore eruption the size of a dime on my lower lip and I thought I'd try about anything to speed along it's demise. I came across many sites listing Apple Cider Vinegar as a topical solution and I remembered my grandfather using it for burns and cuts. The fact that it's all natural was a major selling point, so I decided to give it a try. I had already had the sore for about 24 hours when I started applying 100% Apple cider vinegar directly to the sore with a Q-Tip. It was at the red sore with white blister stage, but hadn't yet erupted or oozed. Well let me tell you, within 5 minutes of applying vinegar it started to sting a little and then pulsate and I knew something was working. I read that viruses can not live in an acidic environment and this was no exception. Over the next few hours, I continually applied and reapplied a few drops and it was as if I had placed a time machine on my sore. What would usually take about 5-7 days occurred over the course of a few hours. My sore erupted oozed, dried out, cracked and crusted over that evening. I then cleansed and applied a little acne medication and left in on overnight to dry the sore further. By the next morning, the scab sloughed off in the shower and I was left with just a dry reddish area of skin, but no sore or bump whatsoever. I was able to cover it with a little concealer (something that NEVER works effectively on an actual cold sore) and with a little loose powder, it was practically invisible. The area is still dry and little painful due to the war that had occurred on the premises the night before, but should be all cleared up by tomorrow and best of all, the cracking/bleeding stage was skipped all together. Essentially, what would usually have lasted 7-10 days for me was complete in just 48 hours. I can only imagine how much better it would have been if I had caught the sore at the tingling stage and applied Apple Cider Vinegar right away. All I can say is that I am AMAZED at the results. Apple Cider Vinegar. Who Knew??? I'm a Believer!

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 would like to ask if ACV can be used on genital herpes??

Hi LIA, for all viruses, including genital herpes, think L-lysine 2 grams (2000mgm) 4 times per day for adults.

even if you have GH, you can still have a family. It does not pass the fetal/blood barrier.You would be given surpressors a few weeks prior to delivery to help ensure a clean vaginal delivery. The only draw-back is if you have a break-out and are ready to deliver. The doctor/mid-wife will not deliver vaginaly if you have a break-out (a) becasue you will most assuradely pass it on to your newborn and (b) it can cause blindness. A break-out will garuntee a c-section.

Well.. it's official.. this last week, what I thought was a zit on my chin, slowly turned into a large festering herpes wound. How fun for me. I don't need a biopsy to know, it's herpes. I've had a bit of a bout with swollen lymph nodes, fever, and overall yuck. I didn't see a doctor because it was the weekend and I wanted to see if it would go away for a day or two. I usually take chinese herbs at the first sign of a cold and never get fully sick, but this lasted more than 24 hours so I new it was something different. As always when something comes up medically I try to research online to feel empowered. I'm here to mention the wonders of Apple Cider Vinegar. My festering wound over a couple of days turned into a giant scab a top a large red mound that seemed to be competing with my nose for who could stick out the farthest. I had read that this was the period when it would heal because it's scabbed but who the hell wants to walk around with a scab on their face. Anyway, this morning after I decided I could no longer look at this awful scab on my chin I used tweezers to remove it hoping it had had enough time to heal beneath. Well, it didn't. Immediately it started oozing and breathing and winking as if to laugh at my naivet'e. I think I even heard it growl once but that may have been the dog next door. Well, long story too long, I decided to use apple cider vinegar on the wound. I just kept pouring it on my chin letting it air dry fully, then any ooze got dabbed off with tissue and then another pour and air dry. After about maybe 10 or so times going through this the gaping wound finally gave up it's relentless fight and went dry with out needing to scab. Victory was mine. The rest of the day it has significantly reduced and I feel like I can almost show my face to the world without being embarrassed. The real problem with the herpes virus is it's friggin' ugly.. If it gets to the point of being an open wound, apple cider vinegar will heal it faster. I've also drank a cap full 3 times today mixed with apple juice. That plus vitamins and L-Lysine for the past couple days may have been helping, but the scabby, woundy part is healed because of straight apple cider vinegar poured on it. I'm confident that I will know the signs earlier next time and use other remedies to catch it BEFORE it becomes the messy roommate living on my face that it became this time. Knowledge is power. Thanks for letting me share in the posters knowledge and to now add mine. Peace.

I was just wondering, How do you apply apple cider vinegar if it's Genital herpes? You know, the sores and all in the insides? does it also, like, heal or helps to keep it from too much itching and burning?

I found this site a week ago and Thank God I did. I have been suffering for 30 years with cold sores from time to time and NOTHING has helped with my cold sores. I have tried everything. So I thought I would try ACV. I put ACV on a cotton ball and held it on my cold sore for a few minutes 4 times a day at the first sign of the tingling. In 48 hours my cold sore was gone! It is amazing! Thank you

I keep organic ACV in the fridge and use it all the time but had never tried it on cold sores which I occasionally suffer from. After a really busy period without enough rest I was starting to feel very run down and sure enough the other morning I woke up with one cold sore above my lip, and a separate one just starting nearby. I thought i'd try the ACV - dabbed straight on with a cotton bud. Immediately I could tell it was helping, so I applied it a few more times during the day. The one that had already started dried up to a mild scab and the other one retreated completely without erupting. Glad to see others know about this too, it really works.

This is probably what I should have done. Instead I held the cotton ball on my lip for 5 minutes or more. My lip swelled and it's still swollen a day later. I'll try this again in the future if I get another sore, but definitely will use it carefully. I used organic apple cider vinegar.

Out of everything that I have used, this was the only thing that took care of the pain and with only one day use. Already the Fever Blister is drying up. Last week I got to much sun and it caused me to get a Fever Blister on my bottom lip... Had me crippled for about 3 days. Had to drink with a straw and had to eat finger food so nothing would touch my lip.. I was in pain... For some reason the internet was my only solution.. Looked up Old Timers Remedy....... Thank God I did... Read all about it, So, found a bottle and poured some in a glass, took a cotton swab and soaked the Fever Blister really good and WOW Pain City for about 30 sec. after the pain left the fever blister did not hurt anymore. I did this on and off all day, now it is late in the evening and the thing is healing. Gods Honest Truth Rem..... No Pain No Gain.

the only cure for cold sores and herpes is apple cider vinegar. i tried everything else and nothing worked. now when a cold sore comes on i immediately douse a cotton ball in apple cider vinegar and hold it on the cold sore constantly --nite and day--until it stops burning. once it stops burning it scabs and begins to heal. with this therapy a cold sore lasts 1-3 days MAX.

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.
