I picked a topic at random, "Ozone" and found quite a few amusing suggestions. A highlight:
A second technique is to introduce the ozone directly into the bloodstream via intravenous injection. The idea of intravenous injection has raised concern with some people concerning the notion of gas embolism which might lead to a heart attack or blockage in the lungs. Gas embolisms, however, do not occur with pure ozone. Air, which is largely composed of 80% nitrogen and 20 % oxygen, will create a gas bubble in the blood at atmospheric pressure, but not ozone. Nitrogen will create a gas bubble in the blood at atmospheric pressure, but not ozone. The rate of ozone delivery and the very small needle used to inject the ozone, guarantee no possibility of gas embolism. Do not allow this bogus fear tactic to keep you from investigating this highly effective and safe therapy!
A third technique is to introduce the ozone gas stream into the colon via the rectum (called Rectal Insufflation).
Crazy!
