Accurately Testing Your PH Level

Thrive-JeffBell_Close_Cropped_Headshot_10-29-2013 For decades most holistic health experts, naturopaths and others have recognized the importance of a proper acid alkaline balance in the human body.  There is widespread agreement that living in our modern, industrial environment renders many of us far too acidic and that this leads to poor health.  Further, this leaves us vulnerable to many serious, chronic health problems such as arthritis, vision problems, neurological disease and even cancers of various types.

Further confirmation of the importance and health benefits of a relatively high alkalinity comes from the spa traditions from all over the world.  If you measure the PH of the water in all of the famous spas around the world you find that it is high.  For example, the water at the famous Lourdes Spa in France has a PH of about 9.5.

A Little Background About PH:
“PH” is a measure of where a given substance falls on a standard scale from acidic to alkaline.  There is controversy about exactly what PH stands for.  I think the most likely candidate is “Potential Hydrogen”.

But this can be a bit confusing.  In an aqueous solution, which is any water-based solution, there are a certain number of dissolved hydrogen ions.   The greater the number of dissolved hydrogen ions in a given amount of the solution the more acidic the solution is said to be.  The fewer dissolved hydrogen ions in a given amount of the aqueous solution the more alkaline the solution is said to be.

What can be confusing is that the actual numbers assigned on the scale for measuring PH are higher when there are fewer dissolved hydrogen ions in the solution.  So a solution with a PH value of 8.5 for example, actually has far fewer dissolved hydrogen ions in it than a solution with a PH value of 6.  I warned you that it could be confusing!

But what is important is to understand that the lower the PH number the more acidic the solution and the higher the PH number the more alkaline the solution.  Furthermore, the scale is a logarithmic scale, so the difference between a PH value of 6.9 and a PH value of 7.0 is quite significant.

The PH scale starts at 0, which is as acidic as a solution can be, and runs all the way to 14, which is as alkaline as a solution can be.  There are complex reasons why the numbers on the PH scale run exactly opposite to the number of dissolved hydrogen ions.  The scale was probably designed that way to facilitate its use with standard chemical equations having to do with molecular measurements.

You don’t really need more detail about PH to understand the crucial information about PH values for good health and how to measure them.  However, for those wanting the detail, here is a good place to start:

What Is A Healthy PH Value For The Human Body?
That is actually a complex question that cannot be answered simply.  Different parts of the human body are supposed to be at different PH levels at different times.  So there is not one single value that is optimum or even acceptable.

There is, however, one exception to this constantly shifting PH picture.  Human blood remain very close to 7.365 just to sustain life.  In order to maintain the blood PH at this level, your body will modify the PH of nearly anything else in your body.

Let’s look at an example:  When the essential mineral calcium is dissolved in a solution will increase the alkalinity of the solution.  If the blood starts to become too acidic, one of the ways the body corrects that is to leach calcium from the bones and dissolve it in the blood.  If this happens enough significant bone density will be lost.  This is known as osteoporosis.

When calcium is leached out of the bones as the body tries to neutralize excess acidity, or a PH that is too low) in the blood, this also increases the tendency for calcium deposits to show up where they are not wanted, i.e. in the lining of arteries.  These unwanted calcium deposits can also show up in the bursa, or lubricating sacs enclosing most joints.  This is one of the common, but all-too-frequently ignored primary causes of arthritis.  (When is the last time you heard a conventional physician advising an arthritis patient that they are too acidic and recommending that they raise their PH?)

What Causes Excess Acidity?
Stress, poor diet, drinking carbonated beverages and lack of exercise are some of the factors that can make the body too acidic.  Of course, if these conditions go on for too long, the blood will start to become too acidic.  As we learned above, in order to neutralize the excess acidity in the blood the body starts to leach calcium from the bones and put it into the bloodstream to neutralize the excess acidity.

Is it any wonder that osteoporosis is such a widespread problem in much of today’s world?

In addition to those listed above, here are a few more common causes of the excess acidity that plague so many of us in today’s modern world:

  • Lack of sufficient sleep
  • Poor quality sleep
  • Poor diet
  • Diet not well suited to the individual
  • Excess sugar in the diet
  • Chronic shallow breathing
  • Insufficient hydration
  • Inadequate time spent outdoors (natural sunlight helps maintain proper PH)
  • Poor digestion
  • Insufficient chewing of food before swallowing

There are more, but these are the most common causes of excess acidity.

What Are The Common Problems Caused By Excess Acidity or Low PH?  (In this article I use “Excess Acidity” and “Low PH” interchangeably.  They are nearly identical – the subtle differences are not significant for the purposes of this discussion.)
The following is a partial list, including only the most common health problems caused by or made worse by excess acidity:  (A few have already been mentioned.)

  • Cancer – both prevention and recovery are adversely affected *
  • Increased susceptibility to diabetes
  • Increased difficulty controlling diabetes
  • Poor digestion
  • Gout
  • Gallbladder disease
  • Kidney disease
  • Heart disease
  • Osteoporosis
  • Loss of mental clarity
  • Poor sleep
  • Premature aging
  • Arthritis
  • Mood swings
  • Dental and gum disease and deterioration
  • Poor cardiovascular fitness
  • Poor eyesight
  • Varicose veins
  • Weakened immune system
  • Increased susceptibility to autoimmune diseases
  • Frequent muscle cramping

*  All of the best German cancer clinics, (arguably, based on results, the best cancer clinics in the entire world), include raising the PH levels relatively high as a major element of their anti-cancer therapy programs.

I could add more, but those are the more common major problems caused by excess acidity.  That should be enough to motivate most people to learn how to properly and accurately measure their PH levels and how to raise them if need be.

How Do I Accurately Measure My PH?
The first thing we need to know in order to answer that question is what to measure.  For example, we already know that our blood must be maintained very close to 7.365.

Because our bodies will do just about anything to keep our blood in that range so that we can remain alive, using blood to measure the PH of our body is neither useful nor practical.  Because our bodies will do just about anything to keep us alive, significant variations in blood PH are the last thing we will see in someone whose PH levels are off.  By then it will be way to late.

A lot of so-called experts on PH for health recommend measuring the PH of either our urine or our saliva.  In fact, the instructions that come with most PH test kits sold as human health aids even recommend measuring urine or saliva.  However, this actually turns out not to be a very good approach.

Our saliva PH levels very widely over even a relatively short period of time.  And seemingly subtle influences change it quickly.  I recently demonstrated this in a workshop:  I measured my saliva PH at 6.8.  Then I did some deep breathing for about 2 minutes and immediately measured it again.  This time the result was 7.2.  That is a huge change in a very short period of time.  It clearly demonstrates that saliva is not a very reliable and consistent means for measuring the PH level in our bodies.

Urine also is not a reliable fluid for determining body PH levels.  While it does not change nearly as quickly or radically as saliva, it still does not produce results that can be reliably interpreted.  For example, suppose I test my urine and find it to be 6.9, (or just below neutral).  That is lower than the ideal level for my body, indicating that at least my urine is somewhat acidic.  But how do I know whether that means my whole body in general is too acidic or if my body is just utilizing my urinary tract to discard some excess acid?  The answer is that I don’t know.  And there is no practical way to determine that without more complex tests.

So how do I reliably test my PH level?  What I really want to know is what the PH level is of the “inter-cellular fluid” – the aqueous moisture in between most of the cells in my body.  So we need to find an easily accessible body fluid that closely correlates to this inter-cellular fluid in PH level.

It turns out that the tear fluid in our eyes is perfect for this.  Whatever PH level we measure in our tear fluid very closely matches that found in the inter-cellular fluid of the body.

Here’s how we can safely and accurately measure the PH of the tear fluid from our eyes:

    1. Stand in front of a mirror with your PH measuring kit nearby and ready.  (Type of kit and sources are listed below).


    1. Rapidly but gently blink your eyes about 30 times to build up some excess tear fluid.  (Never blink or squint your eyes hard as doing so can damage the delicate structures in your eyes.)


    1. When you have built up sufficient tear fluid, gently roll down the lower eyelid of one eye.  (I pick whichever eye looks like it has the most tear fluid built up.  Or I arbitrarily pick one if there is no obvious difference.)


    1. Gently and carefully I bring the end of the PH test stick that has the sample dots on it close to pool of built up tear fluid until the fluid flows onto the stick and saturates the test dots.  I am very careful not to actually touch my eye with any part of the stick.


    1. As soon as the test dots are saturated, wait the recommended 15 seconds and then match the colors against the chart that comes with the PH test kit.  (Most kits are designed for you to wait 15 seconds.  Some may specify a different amount of time.  I would follow that part of the directions that come with your kit.


  1. Note the level indicated by the test.

That’s it.  You now know with amazing accuracy what the general PH level is in your body.

What PH Level Is Ideal?
This is another question that has no really simple answer.  For most people a level that is slightly alkaline is generally healthy.  If you have no outstanding serious health issues that may be related to PH, (see lists above), then a PH of 7.3 to 7.8 is likely going to serve you well.

If you do have health issues that may be related to PH levels or affected by them, then you may want to work with a natural health professional to re-balance your PH level.  Obviously, this needs to be a practitioner knowledgeable and experienced in both PH level management and whatever health conditions you are seeking to address.  If you do work with a natural health professional you may want to share this article with him or her.

Over many years, I have found that there seem to be lots of natural health professionals who are knowledgeable in dealing with specific health conditions and who know how to manage PH levels, but who do not know how to measure PH accurately.  Seems crazy, but far too many still rely on the urine and saliva methods, which we’ve seen are far from ideal.  There is nothing wrong with teaching your health care provider something useful!  Many of the most valuable things I have learned in the field of natural health have come from my clients.  They frequently bring new research and articles to my attention.

Keep in mind that the value range of 7.3 to 7.8 is for general health.  For a number of health conditions, cancer most notably among them, the values should be much higher.  The famous Hoxsey Clinic in Mexico often recommends that their patients boost their PH levels to 9.5 until the cancer is completely gone.  To prevent the cancer from recurring they recommend maintaining a level of 8.5.

Many of the world’s best cancer clinics, (most located in Germany), help their clients to achieve levels similar to those that the Hoxsey Clinic promotes.

Other conditions seem to respond well to other levels.  And there is some controversy, even among natural health professionals about what is ideal.  I suspect that this is an individual factor that is best “tuned” to the individual.  This is why I recommend working with a natural health professional in this area.  This area of health can be complex.

Ultimately, I like to be guided by results.  Things that work well for a given person are most likely right for that person.  If something is not working or not working well, then it either needs to be combined with other measures, or it may not be right for that person.

I believe that in all areas of health if the results are not optimal then some informed analysis and thoughtful adjustments are indicated.  Results are the ultimate measure of effectiveness.

That is one reason why I highly recommend that anyone dealing with any serious health issue maintain a journal that lists:

  1. What measures are bring used
  2. Any test results obtained
  3. Adjustments made
  4. Results in terms of how you feel and how the condition or conditions seem to be responding


Because health issues frequently can become complex and it may be challenging to figure out what is working and what is not, particularly when multiple health measures are being employed, a journal can be an extremely valuable diagnostic tool.  Maintaining a journal also empowers you to better take control of your own health.

What Test Kit Should I Use?
This is crucial.  I have tried lots of different test kits.  Only a few seem to be accurate and even fewer are suitable for using the method described in this article.  I recommend the test kits that include a bunch of small, individual test strips, each having 2 square “test dots” on one end.  These typically come in kits containing anywhere from 50 to 100 test strips.  The plastic boxes that the strips come in also include a color chart.  The increments typically are .5 at both ends of the scale, and decrease to .25 nearer the middle of the scale.  That is sufficient precision for our purposes.

Each time you use a test strip, you wait the required period of time, (usually 15 seconds – included in the kit’s instructions), then you match the 2 “test dots” to a set of 2 sample colors that go together.  This “double match” makes the test highly accurate when properly done.

Here is a picture of a typical PH test kit that I would use and recommend.  Yours does not have to be exactly the same, but it should include individual test strips and should require matching 2 colors each time you test.


It may take a little extra effort to get the right test kit.  But it is worth the time.  Many health food stores and nutritional supply stores carry PH testing kits that meet our needs.  Of course, you likely can find sources on-line, as well.  Just be sure that your kit contains individual test strips that each have 2 test dots on one end, and that the kit is intended for PH testing.  (There are other test kits that look similar but are for testing other factors and not for PH.)


OK, I Have My Measurements.  Now What?
Depending on what health conditions you are dealing with, if any, and what PH levels you are consistently measuring, you may want to employ some measures to adjust your PH level.  For example, many people who suffering from cancer will test at levels that are well below 7.0, (7.0 is neutral and is lower than ideal).  In almost all cases they will want to raise their PH level quite significantly.

There are many ways to raise the PH level.  Frequently it can be done through diet, exercise, changing the type and amount of water that one drinks, increasing the amount and quality of one’s sleep and more.  For some people, adopting a daily meditation practice or similar practice will significantly raise a PH level that started out too low.

The specifics of diet and water to adjust PH are beyond the scope of this article.  Again, if you are dealing with a serious health problem, or if you just want to optimize your health and prevent disease I encourage you to work with a qualified natural health professional.

    Wow! I have been hearing a lot about PH, but no one has ever mentioned the tear measurement. I wonder if yawning is a good way to create the extra tears. I will be ordering the kit you recommend and look forward to using the new method of testing. Thanks again for all the detail. I will be sharing it with some friends right after posting my comment.

      Thanks for a great question. I am not sure if yawning would be a good way to create the excess tear fluid needed for the PH testing or not. First of all, does yawning a lot cause the production of more tear fluid? Then if it does, I would have the following concern: If you breathe more than usual, you will blow off carbon dioxide and this will immediately change your PH towards the alkaline range. For example, if I breathe rapidly and deeply for just a minute or so, my PH as measured in my saliva could change from 6.8 to 7.3. But I am not sure if this change would be reflected in the tear fluid or not. I will test that next time I have opportunity.

      Overall, I have found that rapid, gentle blinking about 30 times seems to work great. Since I was taught that method quite some time ago I have not looked for other methods. Most likely there are other methods that work well. I just do not know what they are and have not been motivated to look for them since this one seems to work so well.

      Feel free to let me know if you come up with more questions or more interesting discoveries.

      Also, since most of us tend to be too acidic, than can have very serious health consequences, I will have a blog post soon that provides some practical measures for raising the PH in the body. In fact, I will have several posts about this. The first one is likely to be about drinking water, which is one of the most effective ways to raise the PH to optimal levels.

      Yes, I am surprised to learn that a number of my readers and clients have had trouble finding the right PH test kits. All 3 of the local health food stores iin my area carry them. But for those who are not finding it easy to get the right kits, (please do NOT get the wrong ones – they will just be misleading), here is a link to buy them via Amazon:

    Since I first posted this blog about measuring PH I have had a number of people complain that they found it difficult to build up enough eye tear fluid to wet the two test points on their PH strips. The answer to that is simple: If blinking rapidly 20 to 30 times does not generate enough tear fluid then that is a sure sign that your body is under-hydrated. Either you are not drinking enough water each day, or the water that you are drinking is not the right kind for your body. (If you are drinking water that is not right for your body, even if you are drinking alot of it, your body still will not be well hydrated.)

    We are each different and need different amounts of water in each 24 hour period. A knowledgable practitioner can help you find your target amount. But a good ballpark estimate is to take half your body weight in pounds and use that number as the number of ounces of good drining water you need each day. Most of us are drinking alot less water than that. If you are drinking alot less, then you may need to gradually increase the amount untl you reach the ideal. Thius can be a challenge, but the long-term health benefits are so dramatic they make it more than worth the effort.

    If you are properly hydrated, blinking even as few as 10 times will almost always generate more than enough eye tear fluid to get a good PH test using the method I explain in this post.

    I have also gotten questions about what type of water we should be drinking. People ask about various filter systems, water ionizers and the like. That is a complex subject. However, I am working on a post that will explain what you need to know to be sure you are drinking water that is right for your body.

    I expect to have this crucial health information posted within a week.

    I have been asked what people who are taking various froms of eye medication, especially in the form of eye drops should do in regards to this test. The specific issue is whether or not the eye drops might distort the results of the test.

    Since there is no way that I can be aware of all of the various types of eye drops that are on the market and in use, I cannot possibly give a catagorical answer.

    However, I have checked a representative sample of the more common eye drop medicaitons. These include drops for soothing sore, tired, red eyes and the like, (which by the way, I am not advocate of), wetting solutions for use with contact lenses, and eye drop medications for glaucoma.

    I have looked into the chemistry of these common medications. It does appear that some of them could distort the results of a PH test that is using eye tear fluid. However, if enough time has elapsed between the use of the eye drops and the PH test, then there should not be significant PH level distortion.

    For example, most of the eye drops for glaucoma are prescribed for use once in each 24-hour period, right before bed. So if you were to use the PH test strip to test your PH level right before you used the glaucoma eye drops, that would mean more than 24 hours would have elapsed between the test and the prior application of the drops. That is sufficient time so that there would not be significant distortion of the results.

    I hope that helps. Thanks for the great questions. Please keep them coming.

    To your great health!

    Hi, Your question concerns me. First of all, I wonder how you propose to accurately measure the PH of your scalp? If you have a way, please share it with me. I do not know of a practical method but would like to. Secondly, if you read and understood the post that your comment was attached to then you would know that testing for PH using either saliva or urine is no good. Neither of those tests will yield accurate and relevant measurements. What you are looking for is to get as close to the PH of the intercellular fluid that is in proximity to most of the cells of your body. It turns out that eye tear fluid is the closest practical fluid that you can measure to get that meaningful body PH average level. The whole point of my blog post is to explain how to test accurately. So perhaps it would be helpful to go back and re-read my post, then let me know if you have questions.

    I also looked at the YouTube video clip you included in your comment. Besides the fact that it shows how to test with urine and saliva, which as I have pointed out does not yield meaningful results, it also indicates that you can test your drinking water with these strips. That also is completely wrong. Testing drinking water for accurate PH should only be done using drops that get added to a carefully measured water sample, then compared to a color reference. There are complex chemical reasons for this. But test strips are useless for measuring the PH of water.

    Lastly, I do not know how to correlate scalp PH, (assuming I knew how to test it), with a specific type of shampoo. I think you are barking up the wrong tree, here. That said, I do not use shampoo because most of the reasonably-priced shampoos have unhealthy chemicals added. Instead, I simply wash my hair with Dr. Bronner’s Unscented, Baby Mild Liquid Castile Soap. In fact, that is the soap I use for all of my body washing needs.

    Please feel free to let me know if I can be of further help in any way.

    To your great health!

I have been on a serious research bender and have a number of new things I will be posting in the near future. I will also soon have an entire section devoted to getting rid of and preventing cancer. And this is real measures that have been found to be highly effective. I am really looking forward to sharing that. Hopefully in about 2 more weeks! I am very excited about this.

    Regarding using the eye drop method – do you still recommend a particular time of the day to test? Or is it usually the same throughout the day?

    Thanks for the great advice

      Hi Mark,

      There is not much research on this that I have seen. But from understanding the biology and physiology involved it would make sense to try and reduce the number of variables. So I would recommend doing it first thing in the morning for maybe a week, and keeping a log. If you see little variation, then I would say the numbers are highly reliable. If you see a lot of variation, then likely there is some factor or health condition that probably ought to be discovered. I could help you with that if need be, but not in general comments. It would take us a session or two to pin it down.

      Hope that helps!

    Thank you Jeff for this educational post. Good quality drinking water is one of the most important factors in good health I think. I get mine from an Artesian Well in the country and it has so much calcium you can see the white in the water. I would assume this would be greater for increasing PH!

    • Jeff Bell
      Posted October 4, 2014 at 7:49 pm | Permalink

      I am not sure that water is so great for you. Too much calcium actually can be a real problem. It can actually cause cancerous tumors to form. For example, it is well known that often there are calcium deposits in breast tissue before cancer tumors form and grow to the point where they are detectable. Since I have no idea what is in your water, nor in what concentrations, I have no idea if it is good for you or not. I would get it tested by a good water testing service so that you really know what you have. I think it is worth the hassle and relatively small expensive to do this.

      It is worth noting that most of the super healthy drinking water that is to be found in the world’s most famous spas, such as Lourdes, do not typically have high calcium contents. Rather, their high PH is the result of natural conditions that do the same thing that a really good water ionizer does.

      And calcium levels that are too high can also lead to heart disease and other serious problems.

      Meanwhile, if you want to protect yourself against calcium levels that may be too high, you might consider taking a good quality vitamin K2-MK7, which acts as a sort of “traffic director” for the body, helping to determine where calcium goes in the body and where it does not and where it may deposit and where it may not.

      To your great health,

    Learn something new every day…Excellent article…I will test my tears from now on. I did test my urine and saliva upon waking up and also about a couple hours after lunch time. I put mineral drops on my reverse osmosis water (water from the local vending businesses)… I have a hand held pH meter for water and it does bring the pH up.

    Thanks Jeff

      Hi Luis,

      It is important to understand that water that has its PH raised by adding minerals has some downsides to it, especially for long-term use. Instead I recommend water that is “split” into alkalized water and acidic water by use of electrolysis. There are many reasons for this. But also keep in mind that most of the water ionizers on the market that do this, are not great. There are a few that are.

      There also is a lot more to optimizing the body’s PH than just drinking the right water. For example, high levels of prolonged stress will make the body too acidic no matter what else you do.

      Contact me by e-mail if you want to know more.

    Hi Jeff:

    Just happened upon your website. I have GERD and a hiatal hernia My doctor prescribed Prilosec and I did not feel well on it. I also read that it decreases your stomach acid and causes bone loss. I already have osteopenia.
    I am trying to change my diet which presently is compulsive. Stress for me is internal so I have been doing yoga.. I love sugary and salty snacks and shop at health food stores for the “healthy” low-fat ice cream pops. I know they are acidic and the monk fruit concentrate that is used to replace the sugar is probably bad for you. Is inulin ok to ingest or is it hard on the stomach?

    Thanks for the great information! A while back I used to measure my saliva with ph tape. Never thought about eye drops and intercellular fluid.

      Hi Marcia,

      Yes, taking Prilosec for any extended period of time is likely to cause a lot of health problems. For one thing, it is likely to disrupt normal mitochondrial function in the cells throughout the body. I think there are much better solutions available.

      There are a lot of variables – too many for me to give you any “generic” advice. However, it you click on the Get Started link at the top of the site and fill in the few questions there, that will put us in e-mail communication and make it possible for me to help you.

    Thank you for such great information! I happened onto this site trying to figure out if tears could become so acidic they could cause skin irritation all around the eye. About 18 mos ago a major event occurred in my life and I suffered greatly. I couldn’t control my sorrow and cried a great deal, still do at times. About 6 months later, I woke up one morning with a very swollen eye. I only wear one contact lense and it was this eye. I have continued to have a big skin issue around this one eye since, and I notice that at times the skin improves greatly and at other times it’s so sore that any tearing feels like it’s burning a crater. I even wondered if I had become allergic to my own tears. I have punctual stenosis of this eye, but it still feels dry a lot of the time. I feel like my tears are like acid, they burn the skin at both corners of my eye and my skin will become very red. I think I will check my pH every day for a while to see if there is any connection with increased irritation and a change in tear pH, or even hydration because I don’t drink the same amount of water everyday, and since I prefer soda pop or lemonade some days. Even pH changes on days of increased stress could be contributing to my problem. Thank you!

      Hi Sandy,

      Sorry I have taken so very long to respond. I had a technical problem that prevented me from seeing some posts. Please accept my apology.

      I have two comments: First, I don’t have enough of your health history to know what is causing the skin irritation. It might be wise to get an eye doctor to look at that and at least give you an opinion. Eye health is so crucial and is just complex enough so that I take a somewhat conservative approach. I recommend getting a qualified, professional evaluation. If they recommend all sorts of pharmaceuticals, you may not want to go down that path, (I wouldn’t), but at least you have some idea of what is causing on, hopefully.

      Secondly, you say that you drink soda pop and lemonade. I would strongly suggest that you stop that practice. There is no way that either of those can keep you properly hydrated and they will not support good health. You would be doing yourself a huge favor, health-wise to ditch both of those.

      To your great health!

    You mention that yawning and breathing heavily might inadvertently alter the pH measurements. But this is BECAUSE subconscious breathing adjustments are one of the body’s pH regulation systems.

    I agree with you that there is a mass of misinformation about pH, but this article seems to replace one mythology with another.

    One of the greatest challenges as we age is maintaining sufficient stomach acid, and drinking alkaline water simply worsens this problem. You mention the baths at Lourdes, but this water is not drunk it is bathed in. Bathing in an alkaline water will drag out acids through the skin. This takes pressure off the kidneys. Poor kidney and liver function can indeed lead to a build up of acids in the tissues, but the solution is not to drink alkaline water. If it were, all the world’s water would be alkaline. In fact, in nature, alkaline waterways quickly bill up with bacteria according to a civil engineering friend of mine who advises at government level.

    In my practice I test both urine and saliva for nitrates, ammonia, sugars, salts and pH and I can tell you that the pH is a factor of the other 4 measurements. I like to see a first morning saliva pH of 7 and urine of 5.8. This then changes through the day, but it shows a proper gradient and a functioning urinary system.

    If you see a higher pH than about 7.2 in the saliva, this is buffering an acid condition and if the urine is too alkaline, this also shows an inability to excrete acidity.

    But again the solution is NOT to drink water where half the minerals have been removed, introducing an electrical charge and challenging the stomach.

    For those who want to get a better grasp of pH, including how the tears compare with other body fluids, here are a couple of videos:

    Finally in the excellent book “The Doctor Who Cures Cancer” by William Kelley Eidem, it is clearly explained how Dr Revici found that while some cancers CREATE excessive acidity, others CREAT an alkaline state.

    To be able to create BOTH acid fluids AND alkaline fluids adequately, it essential to consume plenty of minerals from vegetables and fruits. Then be sure to improve kidney, liver and bowel function. I’m sure Jeff provides excellent information on this elsewhere on this site.

      Hi Jonathan,

      Thanks for taking the time to explain your concerns and the areas ways in which you do not agree with both what I wrote and with what you infer from what I wrote. I am going to respectfully disagree with some of the opinions you share. First let me clarify a few things that I believe are key:

      1. I do not advocate drinking water that has had the natural and healthy minerals removed. I agree that this is bad for health.

      2. I also am not one of those in the alternative health community who says that just drinking alkaline water will fix most health problems, including cancer. I find that position to be dangerously limited in the factors considered and in its conclusions.

      The water I recommend for most people to drink is very carefully treated to remove things like fluoride, chlorine, chloramines, etc. and leave most of the natural minerals in the water. I do think that ionized water at a PH of anywhere from 7.5 to 9.5 is healthy for most people. And, you are correct that this has the potential to dilute stomach acid, which most adults in our society are already deficient in. However, your premise ignores a very important fact of basic chemistry. The PH of the stomach fluctuates from about 2.5 on down to 1.5 or maybe even lower. So ANY liquid we would drink, other than battery acid is going to dilute and buffer the acidity. Obviously, I am not recommending drinking battery acid. (That would be bad!). What I do recommend is drink as little liquid as possible during and close to meals. Drink just enough to lubricate the esophagus so the food, (well chewed and mixed with saliva), goes down smoothly without causing abrasion or irritation to the lining of the esophagus. Do the rest of your drinking well away from meals.

      And I am sticking to using eye tear fluid to gain insight into the overall PH of the body. That is as close as we can get to knowing what the PH of the average inter-cellular fluid is throughout the body.

      I use saliva and urine testing to determine other things, but not PH. I found it to be wrong for determining those values too many times. But I agree that they are useful for looking at nitrates, ammonia, kidney and related detox pathway functions, etc.

      My more than 37 years in this field has taught me these principles and to confirm the validity of my approach.

      To your great health!

    Hi I want to know…is ther any difference in the pH of emotional tear …basal tear or reflex tear. How can we distinguish tear type base on pH. thank you. I am waiting for your reply .

      Hi Madhuri,

      First, sorry to take so long to reply. We had a technical problem which prevented me from getting the usual notices for pending questions. I apologize for that.

      Thanks for a very good question. As far as I know, from a PH point of view, there is no significant difference. This has been tested quite a bit and found to be valid. Researchers had people watch a sad movie and test the PH of the eye tear fluid. Then that waited a few hours and had them blink rapidly and test. the values were nearly identical.

      I hope that answers your question.

      To your great health!

    Hi jeff

    My sister had colon cancer in 2013 that spread to pancreas. She was too weak fir chemo it would have killed her and surgeon said operation not feasible. We decided to use a method widely advertised to increase blood ph by testing urine acid levels and brought it up to 6.8 slightly acidic by using zeolite and a liquid oxygen and a high alkaline diet.

    It worked. In 6 weeks her tumour reduced dramatically, and her health improved.

    So how do you explain that? We had no choice as cells mutate and she was to weak for chemo. We used it initially just to prepare her fir chemo as immune booster we never imagines it will drastically reduce the tumour so she opted for having surgery for the balance. Her GP asked new why did they have surgery for such a small tumour?

    We used the same method this year for my uncle prostate cancer without the zeolite and it worked again. I read that a medical doctor cured her own breast.cancer by raising blood ph.

    So how does one explain that?

    If my sister had the chemotherapy she would not be alive today.

    How do you explain that?

      Hi Wendy,

      First of all, I want to say I am very, very glad to hear that your sister and your uncle survived and got well. That is great news. Secondly, I want to clarify a few things:

      1. I am glad that they did not use chemotherapy. In my opinion no one should. I believe that so-called therapy almost always does more harm than good. It often kills people who likely would have gotten better using other methods. Further, even if one survives chemotherapy and the cancer is eliminated by it, the chemotherapy drastically increases the likelihood of recurrences and secondary cancers. And when such occur after chemotherapy they are almost always far more aggressive and even terminal. So great call to not do it. (By the way, radiation therapy is even worse.)

      2. Based on what you have shared here I cannot explain why what your sister and uncle did worked. Increasing the oxygen level in the body, and raising the PH are often great measures that really help. However, they rarely are enough to do the job on their own.

      That said, I have been dong this work for a very long time. Over those many years, I have seen people I thought had little chance to get well surprise me and do just that. Unfortunately, I have also occasionally seen people I thought would get well who did not. When it comes to human health, there are a great number o variables involved. So there are sometimes outcomes that are not easily explained.

      While we are at it, let me clarify two things here, for you and for anyone else who may read these comments:

      First of all, it is not possible that the blood PH level of either your sister or your uncle were substantially raised. That needs to be pretty close to 7.365. If you could raise it much above that, the person would die very quickly. The body will do everything it can to keep it very close to that value.

      Secondly, I do not recommend using urine to test PH. It changes at the drop of a hat, and so the measurements of the urine’s PH are not very useful. Instead, as per my blog post above, I recommend using eye tear fluid.

      Again, congratulations on your success!

      To your great health!

      Jeff Bell
