This treatment allies the bloodstream in getting fully oxygenated while also oxidizing anaerobic bacteria. Since the portal vein from the colon goes directly to the liver, that is where most of the ozone will end up. Organs and tissues benefit immensely from this treatment. This is a very useful preventative and curative treatment for all colon problems, cancer, purification of the liver and blood, colitis, ileitis, hemorrhoids, Crohn's disease, IBS, herpes, and HPV amongst other std’s.
