Everything is hypothetical at the momment, but it makes sense to me. Here goes; a research clinic at some university did tests on yeast to find out if they produce prostaglandins. They tested both candida albicans and cryptococcus neoformans. They discovered that both yeasts produced significant amounts of prostiglandins which they designated as prostiglandin "X" This substance resembles human prostiglandin "E". Prostiglandins are bioactive lipids which are very important in the regulation of inflammation and immuno-regulatory functions and a number of other important functions involving the endocrine system.
Prostiglandin "e" is like a switch for stomach acid production.

Now, I hypothesize that yeasts and possibly parasites produce this [prost e] as a way to alter the PH levels in the digestive tract by first, reducing stomach acid production. If this is the case, all we need is a cox 2 inhibitor which can prevent the production of prostiglandin e. This could, possibly turn the stomach acid production back "on" to normal levels, and wipe out all these intestinal "pests" within a few days.
The only thing is, the cyclooxygenase enzyme[cox 1 or 2] may have to be compatible to the molecular structure of the prostiglandin molocule. So it would have to be a high purity molecule. Asprin is a cox inhibitor. I am thinking it would have to be a more complex drug than this, so I am researching this now. Shroom
