Works exceptionally well
I tried this when my usual expectorant was not available. From the start I was happy with how well it worked. As good and quite possibly better than what I was using. Then I read all the dosage instructions. I have bronchitis and a larger dose is recommended. Using the correct dose it works spectacularly as an expectorant. I can easily say that I have better lung capacity today. My nasal passages are clearer so I sleep much better better as well.
My biggest complaint is the hard to read dosing directions......so at the end of the day.... not much of a complaint at all
