This is from my brother mike. He is in his second year at U Pitt med school and is a master herbalist under Dr. Christopher's program:
"I'm a bit crunched for time right now to give a really thorough answer, but .... just as an intro CF is a genetic disorder that impairs the body's ability to fight lung infections because it messes with (makes it too thick) our mucociliary elevator which is our layer of mucus that lines our lungs and is constantly being pushed up and out by tiny hairs on our cells called cilia. Normal people have a nice fluidity to their mucus layer which allows it to be easily pushed up. CF people's mucus is overally sticky causing congestion and impaired defense vs. buggies. So you can see that lobelia would be high on the list here available through Dr. C at http://superfood.andmuchmore.com . Mucus suppoorters like marshmallow root, chickweed, mullein, licorice, slippery elm are all at http://return.to/organicherbs . Hot Cayenne salve and BF&C from Dr. Christopher's http://superfood.andmuchmore.com Hot fomentations alt. with cold to help break up the mucus. Hot/Cold showers on the area. Garlic and Ginger for immune support. Great diet: Disease Proof Your Child available at http://committed.to/bestdeals
I would add echinacea once per month minimum as well as hot cayenne extract from Dr. C as well. Get the book Disease proof you child and Stop all Dairy!
