I had been getting coldsores regularly for the past twenty years. I also managed to unwittingly infect my four year old son with them. We were getting them every six weeks at least. A homeopath recommended the homeopathic remedy Natrum Muriaticum. I didn't wait for our next outbreak, just took three pilules four times a day for about three days. My son and I have been coldsore free for two years...until this week after a day's skiing I had my first outbreak (skiing for some reason has always given me the worst coldsores). That's why I'm on this site searching for quickfire remedies as the homeopathic remedy is helping but not fast enough for a quick cure. However I recommend it as a way to prevent their recurrence.
