That is awesome regarding the Diatomaceous Earth! Where do you buy this? I've read that it does kill parasites, but never used it yet.
Regarding further purging out your lungs-- I know that Barefoot Herbalist sells tincture bottles of "Air Restore" -- I beleive he still sells them. I know that he may still sell it at his online store, but this website also provides it http://shop.toolsforhealing.com/category_s/4.htm
I bought some, it works- and clears out alot of mucous from the lungs-- you'll cough up some phlegm with it- and may even have more of an urge to cough (with people around you thinking your coming down with a cold) as the herbs in the Air Restore work on dislodging the mucous in the lungs.
