regarding alcohol "is it good for the eyeballs ", this is just my opinion, but I kind of look at this a windshield washing fluid for humans. When you think about all the gunk the human eye is exposed to externally (not to mention internally....okay, I mentioned it ;) factory pollution / smoke / exhuast / etc, a lot of that comes in contact with our eyeballs whether we see it or smell it or feel it or not.... so it sort of makes sense that it requires a strong solution to wash off the eyeballs.
Regarding the Christopher formula, I got mine from MH, it is either exact OR close to the same recipe as Christopher, with cayenne, and only 2 or 3 drops in the cup per eye does produce a decent amount of flushing of the nasal cavity (immediate runny nose) ..... similar to the effects from doing Schulze's Herbal Snuff. So, aside from cleaning off the eyeballs, it also flushes out tear ducts and such.
