Having investigated MMS, a few years ago, when it became the darling panacea cure-all of the internet, I found no, none, zero credible science to back any of Humble's somewhat extravagant claims.
As an enthusiastic proponent for nano-catalytic silver hydrosols, which already accomplish everything that Humble claims MMS will, but has reams of credible, independent science supporting its safety, non-toxicity and efficacy, I was astonished to find my inbox clogged with inquiries about MMS, from people who should know better.
MMS may do what Humble claims that it does, but until I see some safety studies and clinical research, I grudgingly have to concede that this is probably one example where the quackbusters may have it right. Chlorine, in any form, is best not put into our bodies.
For those in this thread who commented on their dental/gum problems responding to MMS, I would suggest trying a teaspoon full of pure elemental nano-silver sol as a post brushing mouthwash, gargle and swallow. It will eliminate pathogenic bacteria in the mouth. Gum problems will clear in a few days and bad breath, cankers, as well as dental carries will become a thing of the past.
This brand of silver was also EPA approved for sterilization of dental clinic water lines (one of four EPA approvals to date). That is the dentist's water that you rinse your mouth with during and after oral procedures. This approval was not issued without verification of the volumes of safety studies which were included in the original application.
This product is made by American Biotech Labs (ABL). It is sold by numerous private label concerns under a variety of brand names and multi-level marketing programs, but ASAP and Silver Biotics are the original ABL brandings. Silver Biotics is the label intended for brick and mortar retail, and can be found in vitamin and health food stores everywhere. Our website educates about and distributes the original ASAP branding. Our compilation of summaries of the numerous safety studies can be found here: _http://www.lifesilver.com/safety.htm
Until Humble, et al, can produce any credible, independent research, aside from anecdotal stories, to support their MMS claims, I remain open, but somewhat skeptical about both the safety and efficacy of their creation. The fact that MMS has been available for a few years now, and has yet to attract the interest of the legitimate medical research community does not bode well. It would certainly be reassuring to see some corroboration of Humble's claims coming from somewhere other than sources with a vested financial interest, which is all I have been able to find to date.
