This stuff burns like holy hell when you apply it, the manufacturer makes no bones about this, they tell you straight up. The rest is herbal constituents to relieve pain. What you're basically doing with this stuff is cauterizing the cold sore, and then the other stuff in it helps relieve pain. Never ever apply copper sulfate to delicate tissue like lips or genital skin, it is highly irritating and toxic to skin. It is highly likely you will make the cold sore worse by introducing it to a toxic chemical, causng infection.

It is stannous flouride .4%(by total volume) These solutions are not meant to be applied to skin, but rather used as diluted oral rinses meant to be spit out after use for gingivitis, tooth sensitivity and cavity prevention. There is no clinical evidence that stannous flouride is effective against HSV-1 or HSV-2. These are snake oil treatments. See your doctor if outbreaks are a problem. They can help you come up with a treatment plan that is effective. All the best.
