Bael (Aegle marmelos) has a long history of use in traditional Ayurvedic medicine, where it is revered for a variety of health benefits, primarily for digestive, anti-inflammatory, and antimicrobial properties. In the context of bloodshot eyes, Bael is sometimes mentioned in traditional texts and folk remedies as being beneficial, typically administered as a juice or poultice. The rationale in traditional systems is that Bael's purported cooling and anti-inflammatory effects may help alleviate redness and irritation in the eyes. However, these claims are primarily anecdotal and based on centuries-old practices rather than rigorous clinical evaluation.

There is a lack of direct scientific studies examining the effects of Bael specifically for bloodshot or irritated eyes. Modern research on Bael has focused on its antioxidant, anti-inflammatory, and antimicrobial properties, but these studies generally investigate systemic effects or applications unrelated to ophthalmology. As a result, while some constituents of Bael might theoretically benefit inflamed tissues, there is insufficient evidence to directly support its use for bloodshot eyes beyond traditional or folk medicine claims. Therefore, the use of Bael for this particular condition should be considered traditional, with minimal supporting evidence by modern scientific standards.
