My question: My 78-year-old mother has cataracts. She purchased your herbal eyewash tincture and started using it. I explained to her that it would smart a little at first, but she seemed o.k. with that. After a day or two into the process (I told her to use it 6 times a day), she quit. She said it hurt her eyes and made them swell up. The hurting part I expected, of course, but my question concerns the swelling part. My thought was perhaps this is a sign that it was working! But I need to know your comments before I can advise her further. She was using 3 drops of the tincture to an eyecupfull of water.
