Rather than soft like a mushroom, chaga fungus is hard, almost as hard as wood. It is unique, nothing like common mushrooms. In fact, chaga is the most nutritionally dense of all tree growths. Chaga is powerful, because it contains the nutrients—the force of actual trees. Because of their special, biologically potent substances, trees live long, far longer than herbs. Some trees live as long as 10,000 years or more. Thus, they are the most powerful living beings in the world. Concentrating this power, chaga contains numerous B vitamins, flavonoids, phenols, minerals, and enzymes. It is also one of the world’s densest sources of pantothenic acid, and this vitamin is needed by the adrenal glands as well as digestive organs. It also contains riboflavin and niacin in significant amounts.
