I know many of us on here are taking supplements not only for dry eyes, but for other problems as well. So I thought I should post what I found to be the negative effects of valerian. I noticed that while taking valerian for sleep problems that my dry eyes become much worse!! When I stop the valerian, my eyes improve, then if I re-start the valerian, I look like I have pink eye, so I've stopped taking valerian on a regular basis. The bottom line is that supplements can have adverse side effects on the condition of dry eye.
