I'm referring to a machine that can "quickly" flush out/sterilize a gut that has been "completely" over taken by mainly fungal candida/ perhaps bad bacteria.

Basic peristalsis/cleansing programs can not restore the flora balance that has been permanently lost(for more severe cases). Food or probiotics( 2-20 strain) does not "replace" the very complex diversity of hundreds of strains of flora found in the human gut. People with severe dysbiosis or little to no good flora can be very complex cases.

Simple peristalsis or cleansing waves can not eliminate a gut that is has been "completely" overtaken by bad bacteria or fungal candida. It's a little more complex than that. Most people don't realize or understand how strong fungal candida is. Their cell wall is much stronger that any typical cell wall. If someone's gut( 80% of their immune system) is overtaken by fungal candida than it is going to be near impossible for our white blood cells to kill a gut full of fungal candida. Its like going to war and your outnumbered 8:1 and the enemy has stronger armor. The only thing that is keeping the enemy from attacking is a constant supply of food. In other words,as long as fungal candida is being fed it will most likely stay in the gut. If a whole gut filled with fungal candida decided to invade the bloodstream that individual would most likely be deceased.

Now that Pepsi has decided to introduce their diet drinks with Splenda start to see people with more severe cases of gut imbalances(for people that drink a lot of Diet Pepsi everyday).
Sucralose is like indigestible gut poison to our good bacteria. Dr. Mercola has some input on this. Splenda along with sugar alcohols is my reason for severe gut imbalances that is incurable.
