Sayan Siberian Pure Raw Chaga Mushroom Chunks are wild-harvested from birch trees in Siberia. These chunks come with their nutrient-rich black top crust, which is the most beneficial part of the mushroom. They are dried at 14% humidity to preserve their potency. Chaga mushrooms are known for their high antioxidant content, which helps protect cells against free radicals and reduces oxidative stress. They support the immune system, promote digestion, and provide a caffeine-free energy boost. These chunks are ready to use without the need for cutting or sawing and can be reused twice. They are perfect for making a tea that has a soft flavor and earthy taste.
