Rheumatic and kidney problems Birch’s unusual combination of actions makes it a valuable remedy in conditions where symptoms reflecting kidney weakness—poor urine output, fluid retention, and puffiness—occur side by side with rheumatic problems such as stiff and aching muscles, arthritic pain, and leg cramps. By aiding the clearance of waste products in urine, birch leaves increase the body’s ability to remove waste products from joint and muscle tissues. The leaves contain aspirin-like substances which contribute to their ability to control inflammation and relieve pain. Traditional uses of birch include rheumatic pain, gout, fibromyalgia, and kidney and urinary tract infections such as cystitis. A warm decoction of the leaves and twigs can be applied to ease stiff and aching muscles. The sap is thought to have diuretic properties.
