A cure for cold sores

I can’t take credit for this cure. A life-long nurse told me about it a few years ago, and it’s worked for us ever since. I’m not sure if she’d be comfortable having her name revealed here, so I won’t do it. But I’ll always be grateful to her for the advice.

In a few words, cold sores are cured and even prevented by Lysine. Any brand should do. Just go to your local supermarket or drug store and pick up some Lysine pills. They’re white, round, medium-sized as pills go, and they’ll do a number on your cold sore.

I, for example, have had these things since my childhood. Whenever I got stressed, or ate too much sugared stuff, or happened to be recovering from a cold or some other illness and my immune system was down, I got a cold sore. I used to be terribly embarrassed about them, and I still am, to some degree. Sometimes I’d get them four or five times a year, and each one took about 2-3 weeks to go away completely.

Now, whenever I feel that tingle in my skin and know that one’s on the way, I take a Lysine pill. You can take up to 3-4 pills a day, just don’t take them all at once. It’s not a sure-fire, 100% kind of thing, but I would say the overwhelming majority of the time, the cold sore doesn’t even show up on the skin. It just goes away. And when it does manage to break out, taking Lysine while you have it will make it go away sooner.

I don’t know why other cures don’t work, particularly the useless brand-name cremes that cost upwards of $20 for a tiny little tube (they only make things worse for me) — but inexpensive Lysine does the job just great. For less than $10, you get a huge pill bottle that will likely last you more years than you’ll remember.

    I have used Lysine on cold sores with moderate success. If it doesn’t prevent the sores it helps them go away faster. One can also eat a diet that includes food rich in Lysine. Meat, fish, cheese, and beans top the list. I found an article about this in the Saturday Evening Post back in the mid 80s.

    I also find it helps to avoid excessive sweets, corn [especially corn chips], peanut butter, and raisins. Watch out for Oatmeal cookies with raisins in the ingredient list. I can only eat corn chips with lots of cheese or bean dip. That seems to balance things out somehow. It’s related to the amino acids the virus needs to live.

    The creams don’t seem to be very helpful. But taking Lysine along with the prescription capsules knock herpes simplex virus down twice as fast. Also do everything you can to avoid chapped lips or abrasions in the effected areas. If you get the sores, you know where, it helps to use plenty of lube.

    Lysine is a therapeutic orphan. It is a treatment that works but gets ignored in American medicine because the drug companies can’t make a profit on it. There are many other therapeutic orphans. If America gets smart we can use them to reduce the cost of medicine. Beware the Codex Alimentarius (World Food Code).


    • Arthur, thank you for your advice! I guess Lysine works somewhat different on each person. I myself have found that it does help prevent my cold sores from appearing, if I take it as soon as the skin starts to tingle. Sometimes though, it just doesn’t do it, and that’s when I’ve eaten lots of different kinds of sweets. I can definitely relate to your experience with oatmeal cookies that contain raisins. Until you told me about it, I didn’t make the connection, but now it makes sense. Thanks again!

    Nice! Great info and good to know. Especially from a few people with actual field experience with the suggested remedy.

    Nothing like avoiding some personal embarrassment or nipping the old trusty “herpes” jokes in the bud if you can help it!


  3. Raoul,

    I completely agree. I’m get cold sores every now and again, and I hate them. I heard about Lysine from somewhere and immediately started taking it whenever I got a cold sore. It’s unbelievable that nothing else worked before.

    Good info to share with people.
