Hello, I will jump in and say that I have not used Clear Lung even though I have seen it recommended on a few Bronchiectasis sites.
I will explain my reasoning. I have used herbal medicines, but need to be exceedingly cautious when I see a long list of ingredients because I take a few prescription medications, which may interact with one or more ingredients. And I have allergies to a number of plants and pollens. Supplements such as Clear Lung are not regulated by the FDA, nor tested for purity or safety by them. I also cannot tell if the distributor has had any testing done by an independent lab.
Instead I have chosen to use just two medications which help thin the mucus, both approved by my doctors. One is long-acting guaifenesin, which thins mucus. The second is the supplement Nacetyl-cysteine (NAC) which some studies have shown to also be mucolytic (lessens and thins mucus.)

If you decide to try the Clear Lungs, maybe you can ask your physician and/or pharmacist about whether the ingredients may interact with any meds you use, especially for blood pressure, heart, blood clotting.

Have you asked your pulmonologist or primary doc about this supplement?
