Synopsis
Source of validity: Traditional
Rating (out of 5): 1
Boldo (Peumus boldus) has a long history of use in traditional South American herbal medicine, primarily for its effects on the digestive and hepatobiliary systems. Its use to support kidney health is less prominent but does appear in some traditional practices, where boldo is considered a mild diuretic and thus thought to assist in flushing out the kidneys. The leaves contain essential oils, alkaloids (notably boldine), and flavonoids, which are believed to contribute to its medicinal properties. However, the bulk of scientific and ethnobotanical literature focuses on its applications for liver, gallbladder, and digestive complaints rather than direct renal support.
While there are a few references in traditional herbal texts to boldo's diuretic actions, and it may be combined with other herbs in folk remedies aimed at promoting urinary tract health, robust evidence or consistent traditional endorsement specifically for kidney support is lacking. Contemporary scientific studies on boldo are sparse and mostly relate to its effects on the liver, with only minimal research investigating its impact on the kidneys; these studies do not provide compelling evidence for boldo as a kidney-supportive herb. Therefore, its use for this purpose is primarily grounded in tradition, with a low evidence rating.
