Morus, commonly known as mulberry, has a long history of use in traditional Chinese medicine (TCM) for supporting eye health. In TCM, the fruit (Morus alba) and its leaves are believed to nourish the liver and improve vision, based on the theory that the liver is connected to the eyes. Traditional preparations often include Morus as a component in herbal formulas designed to address symptoms like dry eyes, blurred vision, and eye fatigue.

However, scientific studies specifically investigating Morus for eye health are limited. While Morus alba contains compounds with antioxidant properties (such as flavonoids and anthocyanins), which may theoretically help protect ocular tissues from oxidative stress, direct clinical evidence supporting its effectiveness for eye health in humans is minimal. Most research has focused on its potential antidiabetic, anti-inflammatory, or neuroprotective effects rather than direct benefits to vision or eye structure. Therefore, the primary justification for its use in supporting the eyes is rooted in traditional practices rather than modern scientific validation.
