Just looking at the water idea, nice bit here
It is said that drinking water enriched with oxygen is healthy, particularly for people practicing sports. Hence, Oxygizer water was developed. Oxygizer water comes from the Dolomites and contains up to 150 mg of oxygen, about 25 times the amount of regular tap water. It is also referred to as ‘Vitamin O’.
Visiting the website of the company that developed Oxygizer water teaches us that it was developed to improve oxygen uptake, for three reasons:
- To increase oxygen uptake in cities that cope with a lot of smog and other air pollution
- To prevent oxygen deficiencies for people with breathing disorders
- To enhance oxygen uptake after heavy physical exercise
However, Ben Goldrace sent an article about Oxygizer water to Bad Science, not believe in its actual mechanism. He put the water to the test, and stated that as humans would take up about 3,000 mg of oxygen a minute after heavy exercise, one would need 600 mg of extra oxygen a minute. To achieve this amount with Oxygizer water one would have to drink 40 litres in 10 minutes, or 1 litre every 15 seconds. This is impossible, as the human body is usually poisoned when more that 5 litres of water are taken up daily."

The placebo effect is well known and used in main stream medicine and I suspect that its the placebo effect that works for many folk much of the time who use herbal remedies. Also remember the body often heals itself and herbal remedy could in fact have nothing to do with you getting well.
If it works for some then go for it. Its only half a century or so back that mental health patients were given hot mustard baths or sent into a coma with insulin, science moves on though.
