Thankful to have found CS for daily preventative for occasional cold sores. I am actually allergic to the cold sore virus so when I get them, I have a severe skin reaction. Using CS to treat a cold sore coming on plus a few other natural remedies, stops the cold sore and then stops the allergic reaction. Daily helps to keep the cold sores away.
I love the refill options for safer shipping (no bottles to break). I just keep my glass bottles and refill them. Work great!
