Lindera aggregata (commonly known as Wu Yao in Traditional Chinese Medicine, TCM) has a long history of use to support the bladder and urinary tract. In TCM, it is regarded as a herb that "warms the kidney," "disperses cold," and "promotes the movement of Qi," especially in the lower abdomen, which includes the urinary bladder. Historically, Lindera aggregata is used to address symptoms such as frequent urination, urinary incontinence, and lower abdominal pain—conditions thought to be linked to "cold" or "deficiency" affecting the bladder and kidney meridians. The herb is often found in classic TCM formulas for urinary disorders or to relieve discomfort attributed to stagnation or cold in the lower body's organ systems.

Scientific studies on Lindera aggregata relating specifically to bladder health are limited. While some modern pharmacological research has shown that its extracts have antispasmodic, anti-inflammatory, and analgesic properties, these studies are generally preliminary and have not been widely confirmed in large-scale clinical trials focused on bladder function. Thus, the primary justification for its use in supporting the bladder body system is based on traditional practice and historical documentation rather than strong scientific validation.
