I don't normally read this forum, so I just saw this. I'm so sorry you have been having problems with your eye and a chest cold as well. It's bad enough to deal with just one ailment at a time. The eyes are so delicate, so it makes it hard to always know what to do "naturally" for them. I hope this medication helps you. I know many people advise using mild Colloidal Silver drops for infections, but I do understand that our eyes are so precious to us and we don't like to fiddle around with experimenting with something new that we may have never tried before when it's so critical.
I know I like to diffuse a strong peppermint essential oil in the room I'm in if a cold comes on me. Some people like eucalyptus oil.
FYI: On a personal note. My inbox is messed up and I'm not receiving all my messages for some reason. Just every now and then a stray alert will come through saying that someone replied to one of my posts...but not every time.
