Edited - Don't get too fixated on just one Cockroach..
The other day someone came by to have me look over an EPFX test. First thing I saw is Blood Lead High, Urine Lead High, Lead Poisoning High and the Homeo Plumbum High.
Doesn't take a genius to then remember that Lead breaks over 2k enzymatic pathways and one of those enzymes stops Malaria and other critters (including H.pylori) from surviving.

.. a note on the toxin left behind. This toxin like most is salt soluble. In other words if your salt content is high enough for long enough the toxins will leave you.
For many parts of the body to reach that stage IMAM must be taken frequently. If your tears aren't salty you are already collecting salt soluble toxins!
