I had abpa for six years. I was diagnosed at the Mayo Clinic in Jacksonville Florida. For six years I had every symptom - brown flecked sputum plugs , wheezing etc. I survived on Prednisone. My brother who is a gastroenterologist recommended I begin taking calcium. He said to take slow release citracal with vitamin d3. I began taking one tablet - 600 mg of calcium and 500 mg of vitamin D3. After six months, one day while I was on a cruise, I coughed up a bronchial tree. It has now been 9 months and I do not have a single symptom. I have no idea if it wil work the same for others but it worked for me. I thank God.
