Anyone Ever Try Mullein?

Diagnosed with MAX several years ago. Went thru years of albuterol and then saline was added. Cleared a mess of those little critters from the lower part of the lung but still had the cough. Started taking a dropper of Mullein extract each morning. Nearly a year later no cough, no feeling of mucus in my throat and don't have any mucus coming up w/nebulizer. Sleep thru the night w/o any coughing and none during the day. Am going to ask my doctor to do a CT and see how this is happening. Anyone else out there ever do the Mullein? No side effects of any kind. Feels like I never had MAC - maybe it is gone??? I will be 90 in November - still do all of my own housework. laundry, etc. House is 3/2 2300 sq.ft.
