Chaga is a fungus that grows primarily as a canker on birch trees. It has a hard woody texture and looks black from the outside. 

Even though its woody appearance is different from other traditional fungi, the canker has been recognized for its health properties in many parts of the world.

The chaga used for our extracts is found among the fresh air and pure water of the Catskill Mountains. Harvesting chaga often requires the use of a hatchet, hand saw, or chainsaw because of how woody it is. Ladders and climbing gear can be necessary if it is not growing close to the ground. Cutting chaga from the tree does not directly damage the tree or fungus, however responsible harvesting is important to us, as the conk may become more scarce with its growing popularity. This is why we always are sure to leave some chaga unharvested.

At Catskill Fungi, we harvest Chaga growing on live birch trees in the heart of the Catskill mountains for our extractions.  We use a triple extraction method (ethanol, hot water, and cold water) to ensure that all medicinal compounds are present in the tincture in the way that is most bio-available. The list of bio-active compounds within chaga is extensive. 

Chaga that grows on white or yellow birches concentrates betulin from the birch bark. The betulinic acid that results from the ethanol extraction that we use in our extracts, along with the beta-D-Glucans, have been shown to promote a healthy immune system.

When exposed to sunlight, ergosterol-containing mushrooms produce high amounts of Vitamin D2. D2 has properties which have been shown to aid the immune system as well.
