It All Starts with Certified P Value MycoMedicinals certified organic mushrooms from Paul Stamets and New Chapter are the finest traditional mushrooms grown anywhere in the world, and are the only commercially available mushrooms with a Certified P Value. P Value is a scientific term for the genetic integrity of the mushroom. When Paul Stamets, one of the world's leading mushroom experts, selects a mushroom from the rainforest, he cultures it in rigorously controlled conditions in his laboratories. The growing mushroom mycelium is absolutely genetically identical with the rainforest mushroom that gave it birth, carrying all of its genetic energy and healing force. Mushrooms not grown in such a rigorous potency-assured manner may be hundreds of generations distant from the purity of their genetic heritage, and thus suffer genetic degeneration and lack of vitality. We certify that all MycoMedicinal mushrooms have a P Value ensuring the fullest healing power and potency. All ingredients are certified organically grown and processed in accordance with the Oregon Tilth standards and the California Organic Foods Act of 1990. Mycelium: the Earth's living internet The pure healing force of the mushroom lies in its mycelium. Mycelia are the delicate life threads growing unseen in rainforest soil and wood, culturing organic matter and delivering probiotic nutrients to all trees and plants. Mycelia make up a living internet, connecting the ancient intelligence in the mushroom to all life on earth. It is through the activity of the mycelium that traditional mushrooms confer their maximum healing benefits on our physiologies, and each MycoMedicinal from New Chapter delivers proprietary strains of Mycelium, hand selected and grown by Paul Stamets, in their certified organic culturing media. Our Vcaps with certified organic probiotic organisms, are freeze-dried, non-GMO, free of pesticides and heavy metals, and contain both the mycelium and the underlying probiotic medium. 100% vegetarian, no colorings, binders, fillers or flavorings.
