Yes. It is a matter of "balancing" the ph to a very, very, very exact level. This can be done through a molecular 'key in lock' method, actually pressing a "re-set" button which is built into our DNA. It exists, but is being suppressed by the chemicals produced by pathogenic creatures such as yeasts, protozoa and possibly{others}.
According to my working hypothesis, you can restore your whole system, and return to your pre-ailment micro-flora naturally.
I am researching the molecule which might be able to do this. I am pretty excited about it.
It seems that there are researchers already testing drugs in this area.
