Dr. Tennant doesn't explain his claim that all cells in the body need between -20 mV and -25 mV. Without an explanation his claim is pretty much worthless. But let me make a guess. The optimal blood pH is somewhere between 7.35 and 7.45. If blood pH moves below 6.8 or above 7.8, cells stop functioning and the body dies.
A pH meter measures Ph as follows (http://www.omega.com/techref/ph-3.html): "pH electrodes are constructed from a special composition glass which senses the hydrogen ion concentration. This glass is typically composed of alkali metal ions. The alkali metal ions of the glass and the hydrogen ions in solution undergo an ion exchange reaction, generating a potential difference. In a combination pH electrode, the most widely used variety, there are actually two electrodes in one body. One portion is called the measuring electrode, the other the reference electrode. The potential generated at the junction site of the measuring portion is due to the free hydrogen ions present in solution. The potential of the reference portion is produced by the internal element in contact with the reference fill solution. This potential is always constant. In summary, the measuring electrode delivers a varying voltage and the reference electrode delivers a constant voltage to the meter." "pH electrodes are like batteries; they run down with time and use. As an electrode ages, its glass changes resistance. This resistance change alters the electrode potential. For this reason, electrodes need to be calibrated on a regular basis. Calibration in pH buffer solution corrects for this change. Calibration of any pH equipment should always begin with buffer 7.0 as this is the "zero point." The pH scale has an equivalent mV scale. The mV scale ranges from +420 to -420 mV. At a pH of 7.0 the mV value is 0. Each pH change corresponds to a change of ±60 mV. As pH values become more acidic the mV values become greater. For example, a pH of 4.0 corresponds to a value of 180 mV. As pH values become more basic the mV values become more negative; pH=9 corresponds to -120 mV." Therefore a pH meter reading between -20 mV and -25 mV would correspond to a pH of 7.33 to 7.41. A fairly startling coincidence I would say. I think that this is where Dr. Tennant gets his claim. But his claim is total nonsense in the context he uses it. The pH meter uses a specially designed probe which basically creates a battery that uses free hydrogen ions as the electrolyte. The voltage measured is directly related to the amount of free hydrogen ions in the electrolyte. You cannot use a voltmeter to measure the pH of the skin, a liquid on the skin or a cell. Tennant's claim of doing so is rubbish. Dr. Tennant uses this supposed effect to explain what his device does but it is all show and false science. And there is no way that his device can alter the body or a cell's pH. His device appears to be similar to a number of other devices that are used to reduce pain. Dr. Tennant has several patents but they are what I believe are called application patents. They only patent certain pulse configurations that Tennant's device uses and not the underlying methodology. The other makers of pain reduction devices also have their 'unique' application patents but the underlying methodology is the same for all of them. - Steve N -- The Silver List is a moderated forum for discussing Colloidal Silver.
