My husband and I have been using this cough syrup for a couple of years now. We discovered it here on iherb. We both have asthma and it works to soothe and calm coughs for whatever reason. In July of this year, my husband had a quadruple bypass. Anybody who knows what this is knows that you have a breathing tube down your throat and his was in a little longer than usual. When they pulled it out, it hurt his throat more than the average person. He's had a frog in there for awhile. It didn't dawn on me to try this syrup out on him because it's not like it's a cold or asthma issue. But out of desperation we tried it and it calms down the frog and weird cough he has from the surgery so he gets some relief. I give this cough syrup AAAAAAAAAAAAAAAa+++++++++++++ !! Better than anything OTC.
