Sea buckthorn oil could ease the symptoms of the common condition dry eye syndrome, a recent study has suggested.
Researchers from Finland conducted a double-blind, randomised, parallel trial using oral sea buckthorn oil, containing (n-3) and (n-6) fatty acids and antioxidants.
Participants in the study were between the ages of 20 and 75 and they were all experiencing dry eye symptoms.
They consumed 2g of sea buckthorn oil or placebo oil every day for three months.
The researchers, after conducting follow-up studies, concluded that sea buckthorn oil reduced the increase in tear film osmolarity and, therefore, positively affected the dry eye symptoms.
"Further studies should investigate the effects of sea buckthorn oil on more defined populations and aim to determine the mechanisms of a positive sea buckthorn oil effect," nutraingredients-usa.com reports the researchers as stating.
A new method of monitoring and treating dry eye, called the TearLab Osmolarity System, was launched in Canada recently.
