Government tests clearly indicate the superior benefits of charged ions (300 to 17,000 times more effective) than most salts or metallic forms. Silver ions are 17,000 times more effective in saline blood than metallic silver! Colloidal Silver has a long medical history dating back into the 1930's! The antibiotic benefits of colloidal silver were known in early Greek and Roman times! The positively charged ionic form has well documented broad anti-bacterial, anti-fungal and immuno-suppressive properties plus effectiveness on most parasite eggs. Side effects, according to both the FDA and EPA, appear limited to Argyria, a discolorization of the skin with excessive "silver salt" uptake, resulting in "seven cases of Argyria related to silver products having been reported", according to Barrett of Quackwatch. NEVER GENERATE SILVER WITH SALT! Much equipment on the web is so crude it fails to produce positively charged ions of silver and thus most colloidal silver consumed is very weak (low in bio-effectiveness). Unfortunately, many think raw metallic particles, a non-soluable mineral form, can be used by your body, when only soluable minerals (ions) are! "Colloidal silver is a liquid suspension of microscopic ions of silver. The broader commercial definition of "colloidal silver" includes products that contain various concentrations of ionic silver, silver colloids, ionic silver compounds or silver proteins in purified water... DANGER--Many "so-called" effective Colloidal Solutions are produced by using salts, batteries, honey, tap water. You will know what you are using when you generate Ionic Water with the CollGen2 ICS generator. Concentrations of colloidal silver at 5-10 parts per million (bio-available size) have been found to kill numerous infectious bacteria.
