I used the Lung Repair (Emphysema Spray) recently after a very bad bout of bronchitis . I was on antibiotics for 10 days along with a couple of different medications in a nebuliser and nothing was working so sent away and got 2 bottles from BlueTurtle , not expecting too much I was surprised that, after following instructions that I could start clearing my chest, I took it for about 3 weeks and I am good now, I still have a slight cough but thats all . I am very happy with the product and will be using it again if i have a problem .
