I think the castor oil people are trying for dry eyes is just great. I searched everywhere for years, I too tried many different items and they only worked temp. Then some one told me to try black cohosh sold in all herbal stores, it's sold as a capsule, I take one every morning, and it's great for every day. I also found that my dry eyes are caused from a virus. So I am working on the whole body one day at a time, one body part at a time. But good luck & I just thought I would share some extra back up info.
