Yoe91- We are talking about all chronic infections. Parasites, bacteria and virus's.
Some of us were able to see the larger parasites after cleansing. There are many pathogens that cannot be seen but can be identified by symptoms and possibly some testing. Tests are notorious for coming back as a false negative so this can be difficult.
Maybe "your old treatments" could be revisited if you are having ongoing symptoms of a chronic infection.
I myself had a whole bunch of different infections.
The protocol will depend on what types of infections you have. You could start with a simple parasite cleanse and see how you do. Maybe something like the Kroeger Wormwood Combination. Looks like a good mix of herbs.
