Whenever I feel a cold coming on, I start taking this every hour and it knocks it out in a day or less. Works great for clearing up a snotty/runny nose. I mix 2 drops each of MMS/activator, add a littler water, then 2 drops of DMSO, tilt my head back and using an eye dropper, drip it down my nasal passage ways. Clears it up in 1/2 day.
