Black Seed Oil in just a few days relieved my terribly dry eyes. They were so bad that I had to use ointment in them at night, sometimes if I didn't, when I would wake up they would be so painful and feel like they were ripping. I had an antibiotic ointment by the side of my bed, and I would put over the counter ointment in my eyes regularly. I was amazed that in just a few days, taking a tiny dosage (1/4 teaspoon) of black seed oil, I had no trouble with dry eyes at all when I woke up in the morning! I do not know if I have Sjogren's, but I do have some of the symptoms, I just haven't been tested yet.
