I read about it several years ago when my gut was doing its thing. (DX Crohn's, but dubious.) I was seriously considering it; humans have always lived with parasites - some harmful and some symbiotically.

But before I pursued it, I found the Specific Carbohydrate Diet, and that put my gut right to my satisfaction.

I think it would take some convincing to persuade me to try it for PN. I'd have to be certain that my PN was related to something that the partasites could, and would treat safely and effectively.
