I use Albuterol & 7% Saline solution twice a day and have a problem bringing out the mucus using the Aerobika. A good friend who is a RN-PHD gave me some Elderberry Tinture which I took for about 6 weeks which I shared with my husband who has a bad heart and he said it makes him feel better. Was running out of the Tinture so checked some things out on line and found that Tinture & Extract are the same recipe except for alcohol which is in the Tinture. During my search I found Mullein Extract and ordered it along with a Mullein capsule which is supposed to "clean lungs". I started bringing up the mucus from my lungs by the carload! I had a CT just this past week and learned that the mucus buildup in my right lower lung area has been resolved! I let my doctor (Mayo in Jax) know what I had been using - hoping to hear back after the weekend how she feels about the Mullein. PS - I will be 90 years old come November.
