Sargentodoxa cuneata is a climbing shrub whose stem is used in traditional Chinese medicine, where it is known as Da Xue Teng. Historically, it has been employed for its purported anti-inflammatory, diuretic, and detoxifying properties. In the context of supporting the bladder and urinary system, traditional Chinese medicine texts cite its use in formulas intended to clear heat, eliminate dampness, and promote urination—particularly for conditions interpreted as "damp-heat" in the lower burner, which can manifest as urinary tract discomfort, painful urination, or blood in the urine. These uses are primarily based on centuries of empirical observation and traditional theory rather than modern biomedical research.

Scientific studies on Sargentodoxa cuneata are limited, especially concerning its effects on the bladder or urinary tract in humans. Some in vitro and animal studies suggest it contains compounds with anti-inflammatory and antimicrobial activity, but these findings have not been robustly translated into clinical evidence for bladder health. As such, while its use for bladder support has a longstanding traditional basis, scientific validation remains minimal. Therefore, the evidence level is rated as "2"—reflecting strong traditional use but limited modern scientific corroboration.
