Thanks for your reply. I would have the Human bacteria infusion treatment - so it's pathogen free (no bad bacteria or parasites).
They are quite difficult to get though, which is why I want to make sure that it's Worth all the effort to get one. (Doctors aren't that willing to prescribe them to you.)
I'm unsure whether or not it would have any effect as long as my liver and kidneys are so messed up. I've had candida overgrowth for 7 years now + I just found out that I have parasites.
Goat colostrum - has it worked for you? I'm thinking of perhaps trying goats milk kefir - but they recommend that you use unpasteurised milk - which scares me since I already have parasites.
