Birch (Betula species), particularly its leaves and bark, has a long history of use in traditional herbal medicine across Europe and Asia for the management of gout and other rheumatic conditions. Traditional herbalists have recommended birch teas and extracts as a “blood purifier” and mild diuretic, with the aim of helping to flush excess uric acid—the compound that crystallizes in joints and causes gout—out of the body through increased urine production. This use is found in several historical herbal texts, including those by Nicholas Culpeper and in European folk medicine. However, scientific validation for birch’s efficacy in treating gout is minimal. While birch leaves do contain flavonoids and other compounds with mild diuretic and anti-inflammatory properties, there is a lack of robust clinical trials or modern research specifically demonstrating that birch can significantly reduce uric acid levels or alleviate gout symptoms in humans. Most evidence is either anecdotal or based on traditional uses, with a few in vitro or animal studies suggesting possible anti-inflammatory effects. Thus, while birch’s use for gout is supported by tradition, it should not be considered a replacement for evidence-based medical treatments.
