I don't know if Dr. Schultze's eyebright contains alcohol, but you could call the # on the website if you wanted to know.
Here is a sentence from Dr Schultze concerning alcohol in tinctures:
If you’re still concerned about the alcohol, you can place the tincture in a cup, pour boiling water into the cup, and the alcohol will evaporate in seconds.
If you were going to dilute the tincture anyway, it seems you could do so by using the boiling water. Then you could use the one you already intended to buy without worrying about the alcohol.
Maybe someone else has an opinion on this boiling water method, as I have never tried it.
