Why not try Dr. Christopher's or Schultz's Eyebright tincture formula in an eyewash and internally? Over on the Natural Healing forum, there's a thread on how to do it. You'll need a glass eyewash cup and distilled water to which you add drops of the tincture to it and hold the cup up to your open eye and roll your eye around to get the wash all over the eye. Uniquity (forum owner) sells the tincture and if you google eyewash cup you'll find several places. Starwest is supposed to have a smaller sized cup that fits better and seals better so you don't have it leaking out and running down your face as you have your head tipped back.
