In the past, a decoction of leaves or bark was used externally to treat dermatosis, or internally to treat rheumatism. The sap, which is extracted in spring by drilling a hole into the trunk and inserting a tube, is a diuretic and helps rid the body of toxins. A sparkling drink can be made from it. The silver birch is also used in intensive treatments for rheumatism, water retention and skin problems.
The sap is rich in trace elements and minerals - nutritional elements necessary for the skin. It helps to combat skin sagging and invigorate the skin.
