Betula pubescens comes from Northern Europe. It occupies 1% of French forestland.
It can be found in Siberia and in Greenland.
Birch is often planted in parks and gardens thanks to its white bark and graceful drooping branches. The wood is excellent for sculpture and for cooking utensils such as wooden spoons and spatulas. The sap contains approximately 1% sugar. It can be drunk or fermented as wine. Traditionally, it is used in depurative cures, but since the sap contains only a very small amount of flavonoids, it only has a low diuretic effect and will hardly have any effect on the kidneys. Science indicates that for proper detoxification, the extract from the leaves or the bark is preferable. 1-5
