According to Ed Mc Cabe,

Drinking ozonated water is far more effective than autohemotherapy once every 2 weeks.If you want to increase your ozone intake further you can do rectal insufflation using an ozone machine. You can also use the same machine to produce ozone water.You can buy a ozone generator from www.oxygentherapies.com for $399.This is far more cost effective than autohemotherapy.
