Now to try to give a little more understanding to the whole condition.
May I first say that the pH test of both the saliva and the urine are but starting points and only give varied info by themselves.
But the greatest info they provide , which most people may understand from this simple test, is that if one or the other or both are either on the very Acid side or on the very Alkaline side, then you may be sure you have problems.
It is a simple way for most people to see that most of the time that most people are TOO Acidic, and this may be the ROOT CAUSE of most of their SICKNESS and DISEASE, because this may indicate that a person does not have enough Alkaline Mineral Reserves in their body or in the food they are eating to stay Healthy!!!!!!!!
But to try to use the pH test by it's self to determine specific problem areas with specific organs etc, this is a mistake to believe one may do so, for one must use other test, like test with a Refactometer and also a Solu-bridge and other tools to help determine just what Acids or Alkaline Minerals or Protein and what form of protein etc makes up the Saliva and or the urine.
For if you look at each of the different organs of the body, each one contains different colors, Naturally if healthy and UnNatural colors if Sick or Diseased!!! Now this has to deal with the different Light Energy Frequencies which are involved in the presents of that organ which determine if that organ is Healthy or if it is Sick!! This subject is much too deep to even get into on a web forum, for it would only add to the confusion at hand already!!
Keep things simple and follow the Natural ways that man was ment to live by, not the JUNK life style that most who are sick have been Decieved to live by, for the profit of a few!!!!!!!!!!!!
But the above understandings may not be known by most people, as this info takes much study and Wisdom to gain understanding of.
And even myself for what I have been fortunate to learn over many years, do not fully understand it all!!!
What I have learned which I consider the most "IMPORTANT" from all I have learned, is the FACT, that if one stops ingesting JUNK into ones life from all different things, ex: JUNK foods, JUNK environment, JUNK thoughts, and will go back as close to Nature and live a simple life close to one's Creation and in Harmony with one's Creation, that this will bring the best Life and Health that one may desire to have!!!!!!!!!!!!!!!
I have found that it is more important for one's Health to be "MORE" concerned with "STOPPING" the ingestion of "JUNK" life style, than it is of importance of trying to decide what good things to do for your self!!!!
For if one focuses on "STOP" doing the "JUNK" life style, then all else falls in place automatically!!!!!!!!!!!!!!!!
But alas, this seems to be TOO "CHEAP" and TOO "SIMPLE" for most people to consider and thus everyone has problems!!!!!!!
Now to address your question about the saliva test, the saliva should best be above 6.2-6.4 pH for a person to stay Healthy.
What is so important about the saliva to stay above 6.2-6.4 pH is that if it is lower than this, this indicates that the body does not have enough Alkaline Mineral Reserves!!!
Now the importance of this , is that if the saliva is Acidic, then the digestive system will be unable to properly digest the "Carbohydrates, Oils, and Fats" in one's diet!!!!!!!!!!!!!!
This simple test will tell a person that their body is going to become or stay too Acidic regardless of all other tests!!!!!!!!!
Now as too your question about the saliva test being very Alkaline, is this then bad?
One needs to take these tests into consideration with all other factors.
For one needs to take an overview of the saliva test over a time span, for the saliva may change it's pH to one of very Alkaline soon after eating certian foods or even may change more alkaline by just smelling food, if one has enough Alkaline Mineral Reserves in their body!!
This is why it is best to take one's reading the first thing in the morn before eating or drinking anything!!! And do this every day to start to see the differences one's body reactes to the previous days foods that were eaten!!
One may also take test of each the saliva and the urine before meals and after meals to help learn that the pH moves differently depending on many different factors!!
The problem of Alkalosis of the digestive system will be known easily by the FACT that the person will have "CONSTIPATION".
Constipation may be easily solved by taking an enema with a small amount of apple cider vinegar in warm water(the more vinegar, the faster it works) to clean out the colon and by drinking more water and stop drinking sodas, and also by taking a small pinch of Epsom Salt
with each meal!!
So if one is able to "THINK" for them selves so as to consider all matters at hand, then one may solve most any problem easily!!
Hope some of this info may help you.
Smile Tis your choice.
