I'd say water and
oxygen cure have been experimental treatments. But only the water cure has so far made it to the alternative medical scene. If anything, the oxygen we breathe comes laden with all sorts of poison: air pollution, preservatives in food, alcohol, smoking, asbestos, pesticides, etc. So how it can it cure cancer patients? But some doctors still argue that if we inhale the much needed oxygen, cancer patients have more chances for life extension. This is true, but unlike water cure, it has minimal effect on the cancer patient's body.
