Really amazing product. I generally take this is if I ever get the slightest hint of a sore throat. In this case, it stops everything in its tracks and I don\'t suffer any downtime. Recently, I had a rapidly developing sore throat at work and did not have these at hand. I took 3 that night and expected to go down with the cold. However, after a lot of rest over 24 hrs I was amazed to find that it was if the brakes had been put on. No runny nose, no subsequent cough. Back to normal! I hope never to be without these!
