Therapeutic potential of castor o…unction and dry eye.

This review found that castor oil can thicken and stabilize your tear film's lipid layer, which helps reduce dry eye symptoms and tear evaporation. It has anti-inflammatory and antimicrobial properties that may help with blepharitis and meibomian gland dysfunction—conditions that make dry eye worse. Studies showed topical castor oil stays on the eye longer than many treatments, improving comfort and reducing surface damage.
