This is a PDF article as published in the Sept-Oct issue of Natural Life News & Directory, written by the Optimal Breathing Institute's core faculty member, Denis Ouellette. It's on the "greening" of your internal bio-terrain through breathing, oxygenation and detoxification. It reviews some medical history, with Pasteur and Bernard, and how we in the West arrived at our current "disease model" of treating disease. There's a good summary of Otto Warburg's contribution, our understanding of cancer and breathing, a summary of body pH, and how breathing affects it. Some contributions from Michael Grant White's work also.
