The use of pungent compounds (such as those found in spicy herbs like ginger, mustard, pepper, and garlic) to support the bladder body system is primarily justified by traditional medicine systems, especially in Traditional Chinese Medicine (TCM) and Ayurveda. These systems have historically associated pungent flavors with promoting circulation, dispersing stagnation, and supporting the movement of fluids, which is sometimes interpreted as beneficial for urinary function and bladder health. In TCM, pungent herbs are sometimes included in formulas designed to "expel dampness" or to "move qi" in the lower burner, which may encompass the bladder. However, these uses are based on energetic concepts rather than direct anatomical or physiological evidence.

Scientific validation for the use of pungent compounds specifically to support bladder health is limited. Some pungent compounds, such as allicin from garlic or gingerols from ginger, have demonstrated antimicrobial or anti-inflammatory properties in vitro or in animal studies, but direct evidence for benefits to the bladder (such as prevention or treatment of urinary tract infections, cystitis, or other bladder conditions in humans) is lacking or insufficient. Most clinical research focuses on other body systems (e.g., gastrointestinal, cardiovascular) rather than the bladder. Thus, the evidence rating is modest, mainly reflecting longstanding traditional usage rather than scientific validation.
