Bael (Aegle marmelos) has a long history of use in Ayurvedic and traditional medicine systems, primarily for digestive health, but also for supporting urinary and bladder functions. Traditional texts describe bael as having mild diuretic properties, and it has been used for urinary disorders, including urinary retention and infections. The fruit, leaves, and roots are variously employed; for example, bael leaf juice is cited in some folk remedies for relieving dysuria (painful urination) and supporting overall bladder health.

Scientifically, there is limited direct evidence specifically linking bael to bladder health. Most modern research has focused on its antimicrobial, anti-inflammatory, and antioxidant properties, as well as its effects on gastrointestinal issues. Some studies have demonstrated that bael extracts can inhibit the growth of certain bacteria, which might theoretically support urinary tract health, but these findings are preliminary and not specific to bladder function.

In summary, bael's use for bladder support is primarily justified by traditional use rather than robust scientific validation. While its historical application is well-documented, more targeted research would be needed to confirm its efficacy for bladder health in a clinical context.
