Birch trees love sunlight and have strong vitality. They are one of the most vigorous and reparative tree species. They can live in relatively cold environments. They are rare tree species that can survive and self-repair without leaving any traces after girdling their bark. They are often the first to regenerate after forest fires. The secret of the birch tree's vigor lies in "birch sap".
Birch sap is the first wave of water that birch trees draw from their roots in spring. It drips through small holes on the trunk and is a transparent liquid with a slightly sweet plant fragrance. It is only collected once a year, for a limited time of 3-4 weeks (limited time of 10-12 days). The daily output of each tree is very small, so it is extremely precious. Birch sap has a century-old (millennium) drinking tradition in Northern Europe, Russia, Northeast Asia and other places. It is called "forest infusion" and "natural serum". It is not a resin or an extract, but a 100% living sap from the forest.
