Remember, if you have a parasite in your head, you very likely have many more in the gut, because it is where the "pool" of pathogens is.
Partially true, some helminths can live in others specific parts of the body, no necessarily in the small intestine, colon, rectum.
So eat well, liver/colon cleanse, restore proper digestion and optimal gut flora, and the immune system will probably take care of this parasite on his own.
How easy it is to say that when you are not infected by a kind of helminth that your immune system has difficulties to get rid of.
Please do not spread your beliefs as if they were facts, helminths are known to be able to trick the immune system cells in several ways. And the theory of evolution demonstrate that some humans will have less defenses against some helminths kinds depending on the region they have evolved in (even if you believe that a human body has been created by a god, the human body is always evolving depending on its environment).
