Wild Chaga can take years to grow naturally, all the while absorbing and concentrating a variety of healing compounds from the birch tree it grows on. Cultivated Chaga (sometimes not even grown on birch) only takes a few days or weeks to grow and will not contain the full spectrum of healing compounds found in real, Wild Chaga.
