I find the one of the best home remedies for treating and soothing cold sores is using an ice cube made from milk. The ice helps bring down the swelling, and the milk provides natural amino acids called lysine which helps balance out, or bring down the amount of arginine amino acids, which helps prevent cold sore outbreaks.
Now in order to make the ice cubes out of milk you simply need to take an ice cube try and pour some milk into it and place it into the freezer to freeze for 4 to 6 hours. Once the milk ice cubes are ready you will simply remove one of them from the ice cube tray and place it inside a paper towel. Next you will take the milk ice cube wrapped in paper towel and place it onto your cold sore. You will want to hold the milk ice cube on your lip for around 20 minutes or so. This will help speed up the healing of your cold sore and bring down some of the swelling so the sore isn’t so noticeable red and puffy.
The other way you can use the milk if you are trying to prevent a cold sore outbreak is simply by drinking milk every day because milk once again contains lysine in it. You can also eat yogurt and cheeses to get your lysine in your body to help prevent cold sore outbreaks if you do not like drinking milk. The other way you can use milk to help prevent a cold sore from getting bigger when it is first starting out is by simply taking a cotton pad or ball and pour some cold milk onto it and placing the cotton pad or ball with milk onto directly onto your cold sore as a soak. This will help get some of the lysine into the skin where the cold sore wants to breakout so it can help prevent the breakout. I have done this several times and it seems to work really well.
I hope this home remedy for cold sores works for you if you decide to do it. I wish you all the best of luck at making your milk ice cubes for treating and soothing your cold sores, and I also hope the milk ice cube will help prevent and treat your cold sore outbreaks without having to spend tons of money.
