Birch has a multitude of historical uses but is less familiar for its undoubted medicinal properties. The sap makes a clear and refreshing drink that can be preserved as a wine, beer, or spirit. The leaves produce a pleasant tea and an infused oil. In each form, birch is an excellent tonic and detoxifier, mainly working on the urinary system to remove waste products, as in kidney or bladder stone, gravel, gout, and rheumatism. It reduces fluid retention and swellings, and clears up many skin problems.
Birch is one of the most useful of trees as well as one of the most graceful. From adhesives to wine, baskets to yokes, and boats to vinegar, it has been a boon to people in the cold north for thousands of years. Its medicinal properties have been historically valued and should be better known today.
