Those candida sufferers with severe cases must target the colon. Taking oral antifungals will do nothing to those candida colonies glued to the lower intestinal walls. The infection is in the lumen adhered to the mucus layer that cover the intestinal walls.
You need a liquid solution, a poisoned liquid solution able to irragate the intestinal walls to soft and remove the infection.
The water, the antifungal substances, and the persistence doing it every day, will eradicate those fungal colonies soon or later.
I have proved it myself doing it this way. Enemas with clear water to clean the colon, first. You can add sodium bicarbonate to the water enemas, a teaspoon by liter of water, 1/4 of teaspoon of Borax by liter of water, if you want too.(please, NO Boric Acid, it isn't the same as Borax )
When the colon be clean, prepare a solution of 6 ounces of water with 1/4 of teaspoon of Nystatin powder. Inject this solution in the colon, let it goes deep changing your body position several times. Create, use your imagination, take advantage of the gravity and keep this solution inside of you until the next day that you repeat the same process.
The infection is in the cecum, transverse colon, and the lower parts. An intestinal candidiasis can affect any intestinal part but the colon is the worse. Don't think that using oral capsules or tablets you are going to remove infected mucus attached to the intestinal walls. It is a dirty pipe and you need water. You need to empty the pipe, clean the walls, and to apply a disinfectant to those walls . Do it and you will see your life change to a normal health any time.
