Rating (out of 5): 2

Castor oil has a long history of traditional use for various eye problems, particularly as a remedy for dry eyes and minor eye irritations. It has been used in Ayurvedic and folk medicine for centuries, often applied as drops or poultices. The rationale for its use stems from its lubricating properties and its reputation for soothing inflammation. Traditionally, castor oil is believed to create a protective film over the eye, reducing evaporation of natural tears and promoting comfort.

However, scientific validation for these uses is limited. While some small studies and laboratory research suggest that castor oil may help stabilize the tear film and improve symptoms of dry eye—owing to its fatty acid content and anti-inflammatory properties—these findings are not robust or widely replicated in large clinical trials. Commercial eye drops sometimes include castor oil as an ingredient, but often in combination with other agents that have a stronger evidence base. Thus, while the traditional use is well-documented, the scientific evidence supporting the efficacy and safety of castor oil for eye problems remains modest.

In summary, castor oil’s use for eye problems is primarily rooted in tradition, with limited but emerging scientific interest. Anyone considering castor oil for eye application should exercise caution and consult a healthcare professional to avoid potential irritation or contamination.
