You buy a ozone generator, and put the tube from the generator into a glass of water for 15-20 mins. and drink it. If you want to learn more about ozone go to http://alternativecancer.us/ozone.htm for the basic story. You can get a generator for $120-$1,800 or more depending on how serious you are. http://www.plasmafire.com for the $1,800 which are the best & the one I use. http://www.appliedozone.com for medium range generators. And I'd have to look up where the $120 ones are. Naturally the best one works best and comes with everything you need to apply it every way possible. It produces pure ozone too which is best.
