Do you mean green mucous that he is eliminating in his bowel movements? Or do you mean green phlegm that he is eliminating elsewhere...nose, coughing it up, etc.?

If it is the latter, green (or yellow) phlegm is an indication of infection....could be sinus or lung or tooth infection, for example.

There are many natural ways to eliminate infection...olive leaf, oregeno, Colloidal Silver , chinese herbs, ozone, etc. You might want to ask about this in the Ask CureZone Forum where more people are likely to respond.

If he's eliminating green mucous in his bowel movements, I would suggest posting your questions on the Bowel Cleanse (SUPPORT) Forum and the Liver Cleanse (SUPPORT) Forum.

Perhaps you didn't realize it, but you've posted this on a DEBATE Forum and you will most likely not get many helpful responses.

You dad has a gram negitive bacteria that may require an antibiotic. It is REALLY difficult to get rid of these bugs with holistic means. He needs to see his doc.
Good luck!
