It is well known that oxygen plays a key role in every cellular process. It supports the immune system, destroys toxic substances, fuels metabolism, and promotes new cell growth. In 1926, in fact, Nobel Prize winner Dr Otto Warburg of Berlin announced that the cause of cancer was lack of oxygen at the cellular level.
Proponents of oxygen therapy (also called hyperoxygenation, super-oxygenation, or oxidative therapy) contend that increased oxidation in the body can neutralise toxic substances and kill invading microorganisms. They thus advocate oxygen therapy for everything from infections to circulatory problems.
