Rating (out of 5): 1

Rehmannia glutinosa is a key herb in Traditional Chinese Medicine (TCM), often employed for its purported effects on "tonifying the kidneys" and nourishing yin. In TCM, the concept of the "kidneys" encompasses more than the anatomical organs and relates to broader aspects of vitality and fluid balance. Historically, Rehmannia glutinosa has been included in herbal formulas used to address symptoms that, in modern terms, might overlap with kidney or urinary tract disorders. However, its specific use for kidney stones (nephrolithiasis) is primarily based on traditional theory rather than direct historical documentation of stone dissolution or expulsion.

There is minimal scientific evidence to support the efficacy of Rehmannia glutinosa specifically for treating or preventing kidney stones. Some animal studies suggest that certain compounds in the herb may exert anti-inflammatory or diuretic effects, which, in theory, could help reduce symptoms associated with urinary tract issues. However, no robust clinical trials have directly demonstrated its effectiveness for kidney stones in humans. The use of Rehmannia in this context remains rooted in traditional practice rather than validated by modern research. Thus, while it is sometimes included in TCM protocols for urinary health, its role in treating kidney stones should be viewed as traditional, with limited scientific support.
