Seeds to Cleanse Eye, Clary Sage

I'm looking for a seed you place in eye and it moves around and it cleans eye surface. My grandfather use to grow the plant that the seeds came from. He died in 1992 and don't know where I can find these seeds.

However, I would caution you and advise you to not place anything in your eye that may be course and cause an abrasion. A corneal abrasion is incredibly painful and opens up the chance for bacteria to enter which can lead to blindness.
If you are looking for an eye rinse whereby an infusion is made using herbs and the tea can be very carefully strained and used as an eye wash, that is a completely different matter.
