Researchers at the University of Auckland reveal promising results from a pilot study, indicating that castor oil could serve as a safe and effective natural alternative for treating dry-eye disease. Dry-eye disease, affecting approximately 58 percent of Australians aged over 50, is often exacerbated by factors such as aging, menopause, increased screen time, and contact lens use. The most common cause, blepharitis, accounts for over 80 percent of cases, presenting a chronic condition with limited treatment options.

The pilot study involved 26 patients with blepharitis who experienced measurable improvements in symptoms after a four-week treatment with cold-pressed castor oil. The enhanced product, containing mānuka and kanuka oils, applied with a rollerball, demonstrated reduced redness, decreased eyelid thickening, and a decline in bacterial presence. The success has led to an extensive double-blinded, randomized, and placebo-controlled study, aiming to recruit 92 participants for robust scientific evidence. Principal investigator Professor Jennifer Craig expresses hope for evidence-based guidance, envisioning castor oil as a viable management option for improving the quality of life for those suffering from blepharitis.

Castor oil, renowned for its medicinal properties, presents itself as a natural remedy for various ailments. The current trial’s unique application of castor oil on the eyelids offers a potentially safe and easy-to-use alternative to existing therapies for dry-eye disease. With concerns about the side effects and long-term suitability of current treatments, the ongoing research seeks to provide clinicians with evidence-based guidance, ultimately enhancing the well-being and quality of life for a significant number of patients suffering from this chronic condition.
