I'm simply using eyebright herb by brewing it into a tea. I have never tried Dr. Christopher's formulas. I don't even know if you can still find them anymore. This article is from the 1970's I think. Dr. Christopher has other very interesting articles you can find at that same website, lifebalm.com (or whatever it is, I don't have the link at home) I found the lobelia article to be very interesting.
I'll add that it's been 6 days since I started the wash, and last night was the first night that my eyes really crusted up, I had a lot of mucus come out of my eyes throughout the evening, I mean stretchy globs of stuff, and in the middle of the night my eyes became crusted over more than once. I'm glad this stuff is coming out of my eyes. Today my eyes feel firmer and fuller and my lower eyelids look puffier than normal. I usually have dark circles under my eyes but it almost looks like my lower eyelids are filling in and reducing the shadow.
