If you suspect protozoa then I would doubt that the program will work based on my and someone else's experiences. Herbals have little effect on protozoa and I have not found many that can eradicate them. (sorry to be a party pooper :)
Doing the Metametrix GI Effects test (panel #2105) would be a good start if suspecting some gastro based bug - if you think the liver is the place of infection and protozoa then the only think I could think of is e histolytica but this typically shows up in third world countries coming primarily from bad water. It can become liver bound.
I have an outside forum that you might find help in
