I don't have a lot of experience with that issue, but I found what appears to be a great cure from earthclinic.com, which is a great site. It seems that Colloidal Silver AND green tea bags work wonders. Here's the quote I read:
"So what i did was i put about 3 drops of Colloidal Silver in each eye then i placed a warm tea bag over each eye and left it on for about 15-20 minutes (i steeped the tea just as if i were making a cup of tea)and at first when i removed the tea bag i could see the green mucousy stuff floating around in the eyes like it was being pulled out of the crevices or something. it was nasty. but by the 2nd day it had pretty much cleared up. i followed that same procedure-silver then warm green tea bag-about 2-3x a day for 3days and it has not come back! that was almost a month ago. p.s. the secret to getting the tea bags on the eyes of people so young is to wait until nap time or bed time (in case anyone was wondering how i managed to do that). so anyway-thanks for the help! God bless."
