Parasites only a result not cause?

After doing so many tests, I have come to the conclusion that parasites being the cause of chronic health complications is the exception not the rule.
For example, I have a a plasmodium infection, which is a intracellular parasite. This fact may protect me from viruses, because the body is always on alert for cellular invaders.
But, there are other down stream effects which can cause real complications.
There are certain cytokines the body produces when an infection is present. These cytokines [cell to cell communication signals] can induce responses to non- threatening antigens causing psudo-autoimmune reactions and or allergies. All of these reactions will change the chemistry of the body. Much of this chemistry is induced by bio-reactive proteins generated in certain glands, especially the ones controlling hormones. Once this happens, it can cause changes to metabolic conditions which can have consequences on ecoli levels, candida levels, H. Pylori etc. Obviously, this can have other health repercussions which may in some individuals, lead to other parasitic infections.
It becomes a cycle.
Therefore, the health of your cellular responses to disease agents, like viruses, invading fungal metabolites, intracellular parasites, L form bacteria, and environmental toxins, could be at the center of everything.
If you take into consideration the fact that you are being constantly bombarded with every type of disease 'out there' waiting to find a suitable host, some will eventually find a soft spot to get in [the extent of this will hinge upon your genetic make-up].
Most of us [and animals] can handle it, and contain it. But for some, it becomes an issue that impacts on a certain quality of life\health we are accustomed to. Sometimes drugs\herbs\therapy can knock it out, other times it becomes annoying but stable, and in some scenarios it becomes debilitating.
So the big question that I am working on is; how do we knock crap out of the cells\receptors, and flush the system of all the poisons and biologically active elements?
Any ideas? Shroom
