Smilax, commonly known as sarsaparilla, has a long history of use in traditional herbal medicine, particularly in Central and South America, India, and China. Historically, it has been employed as a general tonic and "blood purifier," with some traditional systems referencing its use for supporting kidney health, promoting diuresis (increased urine flow), and relieving symptoms associated with kidney or urinary tract issues. However, these uses are based on ethnobotanical records, anecdotal evidence, and traditional herbal texts rather than rigorous scientific evaluation.

Modern scientific research on Smilax species has focused primarily on their potential anti-inflammatory, antioxidant, and antimicrobial properties. While some animal and in vitro studies indicate that Smilax extracts may have mild diuretic effects, there is insufficient clinical evidence to support its targeted use for kidney health in humans. No high-quality human trials have demonstrated a clear benefit for specific kidney conditions. Regulatory and scientific bodies do not list Smilax as a validated support for the kidney system.

In summary, while Smilax has traditional uses that include kidney support, there is minimal scientific validation for these claims. Its continued use for this purpose is primarily based on historical and ethnomedical practices rather than modern research.
