Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Java Tea (Orthosiphon stamineus), also known as "cat's whiskers," has a long history of use in traditional medicine, particularly in Southeast Asia, for supporting kidney health and treating kidney stones. Traditional practitioners have employed Java Tea for its reputed diuretic properties, which are believed to help flush out kidney stones and reduce the risk of stone formation.

Scientific investigations into Java Tea's efficacy for kidney stones are limited but growing. Some animal and in vitro studies suggest that extracts of Orthosiphon stamineus may increase urine output and reduce the aggregation of stone-forming minerals, thereby potentially lowering the risk of stone formation. Components such as flavonoids, saponins, and rosmarinic acid are thought to contribute to its diuretic and litholytic (stone-dissolving) effects. However, robust clinical trials in humans are scarce, and most evidence remains preliminary.

In summary, the use of Java Tea for kidney stones is justified mainly by traditional practices, with some low-to-moderate quality experimental evidence pointing toward possible benefits. High-quality, large-scale human studies are needed to confirm its effectiveness and safety for this indication.
