(UVC is a specific wavelength of light of the UV band - think UV lights in clubs - it kills bacteria and is now used in hospitals to sterilize equipment ) ...to cleanse the colon of both good and bad bacteria in the intestines in order to immediately cure patients with IBS (Irritable Bowel Syndrome) and Chrons, which are both caused by harmful gut bacteria that even the best probiotics unfortunately do not successfully treat. (Which lead me down the rabbit hole...) If you want to be as sick to your stomach as I am, here is the truth and I am happy to source over 8 case studies out of dozens on the subject which all say the same thing, UVC kills cancer cells as well as COVID-19 and also strong ionized oxygen can kill any virus on contact instantly. Those tiny tentacles of Covid 19 virus will be neutralized in a fraction of a second in contact with the ionized oxygen.
