AS you would have now have an idea about Pulmonary Fibrosis wherein the lung tissue sort of hardens and loses its capacity in the alveoli or the functional part to exchange gases. This could be secondary to certain infections or genetic too. Homeopathic Medicine has good remedies like Natrum sulf, Thuja, Sulph, Amm carb, Plumbum met, Stannum met etc. to see that there is no further degeneration of the lung tissue and the function part which is available, its capacity is increased. I am sure Homeopathy will be of help to him.
