Researchers have completed a controlled study which investigates the immune-system enhancing effects of black currant seed oil, which is an excellent source of omega-3 and omega-6 fatty acids.

Both this study involving 40 patients and previous research suggests that the combination of omega-3 and omega-6 fatty acids which is found in black currant seed supports increased prostaglandin (a fatty compound with hormone-like effects) PGE1 (a type of prostaglandin), which both stimulates acqueous tear secretion and reduces the production of another prostaglandin, PGE2, which causes inflammation that contributes to dry eyes.
