Overview:The leaves of birch trees can be used to make a pleasant tasting tea that is listed in the German Pharmacopoeia as a diuretic used in 'irrigation therapy' for the treatment of bacterial and inflammatory conditions of the lower urinary tract. The German Commission E monograph also recommends the tea for preventing urinary tract gravel and for treating bone and joint complaints. Birch bark tea also has strong medicinal properties and was traditionally used by American Indians for pain relief (due to the salicylate content). The mixture of volatile oils and resins found in birch are similar to those found in wintergreen, whose oil has been widely used as an anti-inflammatory in topical applications for arthritic and neuralgic conditions. Its diuretic and antiseptic actions are a result of a synergistic effect between the volatile oils, saponins, and flavonoids contained in the birch juice. In addition, the bitter glycosides in birch act to stimulate digestion.

Traditional Use/Benefits/Body Systems:As a diuretic and antiseptic for the urinary system, as a blood cleanser, and to treat arthritic joints or gout.
