OK, Let me take a stab at it. First we have the known facts, then the experimental evidence, then the theory that ties it all together.
Facts: 1. EIS kill pathogens 2. Silver salts will photoreduce to silver atoms or particles when exposed to light 3. Silver salts will plate out on silver atoms or particles when there is a developer present and the ph of the liquid is over 7. 4. Many compounds can act as developers, such as caffeine. Some of these compounds may be found in the blood. 5. If silver salts are taken and then a person is exposed to light, then #2 and #3 can result in argyria, even for silver chloride with limited solubility 6. EIS does not cause argyria despite containing silver compounds of silver hydroxide or silver oxide. 7. Silver ions will help healing by causing injured cells to dedifferentiate and redifferentiate, and also quite possibly by repairing dna. 8. Silver compounds will usually form silver chloride when exposed to the stomach acids or salt in the blood. Some, such as silver sulfide will not, but they are not involved at this point. 9. Silver metal or particles are an oxidizing catalyst and a conductor. Experimental Evidence: 1. Both ionic and colloidal forms appear to kill pathogens. 2. Silver ions disappear from the blood stream rapidly after being introduced when there are silver particles present. 3. Silver taken by mouth ends up being eliminated primarily through the kidneys, despite the limited solubility of silver chloride. 4. Silver compounds with silver colloid (EIS) does not cause argyria. 5. When mixed with Gatorade, absorption rate is greatly enhanced. 6. Adding H2O2 increases the effectiveness of EIS Theory: Both ionic silver and colloidal silver kill pathogens, although likely by different means (ions binding with sulfur, particles being an oxidizing catalyst or disrupting the cell electrochemistry, or other means).. When one takes EIS by mouth, the ionic portion converts to silver chloride immediately. Most of the silver chloride precipitates out temporarily. If you mix with an electrolyte solution, then the solubility of the silver chloride goes up due to it forming chloride complexes of silver. (EE #5 above explained). Some of the silver chloride will remain in solution, and will quickly cross the stomach wall into the blood stream. This reduces the silver chloride in the stomach, so some of that which precipitated out will redissolve. Any that has not redissolved by the time it reaches the intestines has a fate which is unknown. Silver particles will also cross the stomach lining into the blood stream unchanged. Once in the blood stream, the silver quickly tries to reduce onto any particles it can find (Fact #3 and #4). There are two cases here that need explaining. First if there are no colloidal particles in the blood, some of it will end up being photoreduced by the sun in the skin (FACT #2). These particles would normally move out of the skin in short order, but with a significant silver compound in the blood, the quickly grow to the point of becoming caught via the photographic process. (Fact #5) If however there is a colloidal component associated with the silver chloride, then they quickly plate out on those particles (FACT #3). The result is a slight increase in particle size, instead of a huge increase in the size of particles in the skin. Thus the colloidal portion acts as a prophylactic against argyria. (Fact #6) At some point the kidneys remove the silver particles from the blood stream. (EE #3). I believe the theory explains all of the above known facts and experiments given above except EE #6, which I will discuss below. If there is any repeatable experimental evidence that contradicts this theory, then the theory will need to be modified or discarded, but at this time is as far as I know the ONLY theory to explain all the experiments, facts and evidence. Enhancement of H2O2 for EIS. 1. EIS contains silver ions and silver particles. The particles are fairly large compared with a particle of 2 atoms. 2. H2O2 will react with large silver particles, producing silver oxide. 3. H2O2 will react with silver hydroxide producing silver atoms which then aggregate with any particles. 4. H2O2 will react with silver oxide producing particles of silver composed of 2 atoms. The final result is a mixture of very small silver particles of typically 2 or so atoms, and silver oxide with a solubility limit of about 13 ppm. Tyndall decreases due to the replacement of large particles with small ones although many many more, color goes away for the same reason. Now I am unable to determine the ratio of silver oxide to silver particles, but if we assume that it is 50/50 then if we follow the above theory we will end up with many more and smaller particles in the blood than if the H2O2 was not added. So what is the difference? Lets say we start with some EIS that is 10% colloidal and 90% ionic. The colloid will contain particles of some typical size, say 15 nm on the average. A 15 nm square particle of silver atoms .2 nm in diameter (square to make the math easier to follow) will contain approximately 45*45*45 particles or 91125 atoms. Now when this reaches the blood stream we end up with 9 times as many particles plating out on these particles making them have 911250 particles total, and the size increases to 97 atoms square, approximately twice as large. If we start with a mixture that is 50/50 mixture of 2 atom colloid and ionic, then we will end up with 4 atom particles in the blood stream, also twice as large as the initial particles. The surface area difference is tremendous between a particle with 45 particles on a side, and particles with the same silver content with only 4 particles total ( 4 atom particles will have 100% of the atoms exposed, a 95 particle cube will have only about 6.4% exposed). The increase in effectiveness should be about 15.67 to 1. I believe that explains the H2O2 enhancement quite well. Now for the question of if adding Gatorade and H2O2 together will be even better. If you do this then the ionic portion becomes silver chloride, which will not change with exposure to H2O2 (verified by Mike M), and the H2O2 will break down the colloidal portion to silver oxide, which will then become silver chloride. The final result will I believe be almost totally silver chloride, very low effectiveness, and with no particles, and could cause argyria. If one added H2O2 and let it do it's thing, then got rid of the H2O2 somehow and THEN added Gatorade, then it should be enhanced though; an interesting avenue of experimenting to maybe follow up on.
