Hi suzynoodle that is amazing that you have not been affected by CF until now - wow what a story. My daughter has CF, she is 5 and was diagnosed at birth. Luckly she has been really healthy and so far so good. You happen to mention herbal remedies and I suggest that getting toxins and removing them from your home is one of the most important things you can do - the EPA says that indoor air pollution is 3 to 70 times greater than outdoor air pollution. I am a firm believer that removing these things from your home can make you proactive instead of reactive and do this naturally as well. I have some suggestions for you and if you want further information you can do so at firstname.lastname@example.org.
