              • caution in those who have a propensity for calcium deposits throughout their body – joints, etc…

              MISCELLANEOUS:

              • The name originates from the Russian word for mushroom, ‘czaga’
              • Siberian and Chinese shamans refer to chaga as ‘the mushroom of immortality’
              • Translates to ‘cancer polypore’ in Norwegian, where it is frequently used to treat cancers

              • Primarily inhabits the trunks of Birch trees, and sometimes Alder, Beech, and a few others
              • Not actually a mushroom; it is a hardened ‘canker’ of dark woody tissue that is parasitic, and draws nutrients and constituents directly from the tree
              • Neither plant nor animal, but its DNA is closer to human DNA than it is to plant DNA
              • Even though Chaga is commonly referred to as a mushroom, it is actually a hardened mass – or “canker” – of dark woody tissue that grows on birch trees
              • Aluminum chelator
