For ancient times, Finnish birch trees have been tapped for their sap during Spring (March-April). The tapping process is halted when the tree shows signs of coming into leaf.
The current practise is not to tap a tree for more than two consecutive years, upon which the tree is left to rest for at least one year.
Studies have shown that such a practise makes tapping harmless for the tree. It enables the birch tree to produce sap that is transparent in colour, just like it should be.
What is it used for?
Birch sap was formerly used in the treatment of various diseases. In modern times, it is used in phytoterapy.
Though not a medical preparation, birch sap is believed to reduce blood cholesterol and relieve such symptoms as hypertension, gout, arthritis and urinary-/kidney trouble. It is used for preventing hardening of the arteries as well as development of cellulites and obesity. Sap also relieves Vitamin C deficiency.
What does sap contain?
Birch sap is mainly water with only 1-2% of dry matter content. The dry matter consists of sugars (fructose, glucose and saccarose), with some matters of maltic, citric, fumaric and succinic acid. Medicinally though, its most important constituents are the trace elements: one litre contains roughly 410 mg calcium, 350 mg potassium, 78 mg magnesium, 27 mg manganese and 50 mg phosphorus. It contains no fat.
How to enjoy birch sap,
Arctic Original birch sap should be consumed in the morning on an empty stomach. An intake of 1 dl a day is recommended. An opened bottle keeps fresh in the refrigerator for about one week. Arctic Original has been flavoured with lemon to give it an extra fresh taste. The sap has been tapped from birch trees in the clean archipelago of northern Finland.
