This Wild Alaska chaga is double extracted in water and alcohol to provide multiple benefits to the immune system. A small quantity of pure organic birch syrup is added for a little added sweetness and inherent minerals. Suggested dosage is 2-3 droppers twice/day under the tongue or in any beverage. Chaga mushroom (innonotus obliquus) is a fungus that grows primarily on live birch trees in cold climates. Acting as a cancer that will eventually kill the tree, chaga draws nutrients from the host tree that can be extracted and used for medicinal purposes. Chaga is high in antioxidants and may be used as an anti-inflammatory and to boost the immune system. There is a great deal of research on chaga. Evidence has been found to show that chaga, if extracted properly, may be effective against cancers and to decrease side effects of cancer treatments. Made in Alaska.
