Tree Turmeric (Berberis aristata), also known as Indian Barberry, has a long history of use in traditional Ayurvedic and Unani medicine. It is commonly employed to address various eye conditions such as redness, itching, and inflammation. The traditional use is primarily due to its perceived anti-inflammatory, antimicrobial, and soothing properties. The yellow alkaloid berberine, present in Tree Turmeric, is often credited with these effects. In Ayurvedic texts, preparations (such as decoctions and eye washes) of Tree Turmeric are recommended for relieving discomfort associated with eye irritations and conjunctivitis.

However, modern scientific studies specifically investigating the efficacy of Tree Turmeric for treating red or itching eyes are limited. Some in vitro and animal studies have highlighted the antimicrobial and anti-inflammatory properties of berberine, which could theoretically benefit eye health, but direct clinical evidence in humans is lacking. Thus, while traditional use is well documented and persists in practice, contemporary clinical validation is minimal.

In summary, Tree Turmeric’s use for red or itching eyes is justified by a strong tradition, supported by plausible but indirect scientific mechanisms, though high-quality clinical evidence is absent.
