You can do high enemas at home. Enemas, when done correctly, will help you to clean your colon very efficiently. I believe you are battling an intestinal fungal overgrowth, so Nystatin enemas will give you excellent results. The key is to hit the colon with antifungals in enough concentration to kill the fungus. Nystatin is fungicidal against candida albicans. It is also poorly absorbed by the gut lining. The problem is when we take it orally, it mixes with food, dead flora, and fecal matter diminishing its activity in the large bowel where the biggest amount of candida colonies concentrate. The small bowel isn’t a good environment for microbial growth because digestion fluids such as protease, HCL, sodium bicarbonate, and bile, make it almost sterile. On the other hand, bacterias and fungus growth in the colon where fermentation, putrefaction and decomposition take place. Most of the antifungal substances are absorbed in the upper intestines when taken orally, so its effect hitting the colon is very weak or nothing. I believe this is the weak part in any anticandida treatment , and the reason because the diet is vital as well as the very long process to get results.
I hope this help you.
