Not terribly expensive, no.
Crunched-up papaya seeds, black walnut husk, probiotics, enemas, and exercise, folks.
If that sounds like a "walk it off" sort of thing to you, I invite you to exercise, eat ground up nut shells, and take enemas next time you're diagnosed with a life-threatening illness.
Clostridium difficile causes very high white blood cell counts, severe pain, crippling colitis, and endless nausea. It can eventually lead to death.
Give it about a year and you’ll get the same results, and almost for free.
No, you'll end up deader than a doornail. "Dead" is free, though, I guess.
There are A LOT of natural, cheap stuff besides the above the kill of yeast, fungus and parasites quite readily.
Clostridium difficile can progress to something called toxic megacolon, which can kill the patient. Painfully, I might add. It kills around 14,000 people in the US annually.
Additionally, it isn't yeast, fungus, or a parasite. It is a bacteria. If you believe that any of what you mention can kill dangerous bacteria, please take a public pledge to never use antibiotics or any sort of anti-bacterial treatment ever.
A better (and quicker) solution is to take Dificid (Fidaxomicin). I have seen it literally save lives. Often folks have been cured in a matter of days. For some reason, few doctors are aware of its existence.
