Sorry to bring this old subject up again, but I just wanted to be sure of how 
to use it.  It seems you can take it internally or put it in the eye.  This 
website says to dilute it.  Do those of you who use it dilute it?  Or can I 
just drop it right in the eye?  It lists alcohol as an ingredient, so I wanted 
to be sure...
