There has been much discussion here and elsewhere on the net about OSR #1, the chelation chemical sold as “oxidative stress relief” supplement. The latest round of this was sparked by a story in the Chicago Tribune, FDA warns maker of product used as alternative autism treatment.
Much of the early investigation of OSR #1, it’s origins as an industrial chelator and so on, were done by Kathleen Seidel of Neurodiversity.com. Ms. Siedel is probably the most thorough blogger (or writer of any kind) I know of. Her posts are long and detailed and well referenced.
Her recent post, OSR: The Littlest Consumer, takes on the subject of internet reports of OSR being given to small children. The website for OSR (CTI Science) states, OSR#1TM is not recommended for children under 55 pounds or under 4 years of age.”
And, yet, OSR appears to be being given to small children. Also, if the internet reports are accurate, this occurs sometimes under the advice of DAN doctors.
People interested in a thorough discussion of OSR can reference previous articles by Ms. Seidel include:

Looking at the posts, all I could think of was Einstein’s definition of insanity, doing the same thing over and over and expecting different results.
Finding no mercury but expecting that ever more and ever stronger and ever larger doses for ever longer periods of time, of chelating agents will take out the mercury that obviously isn’t there.
If you are interested in the paperwork that Mr. Haley submitted to the FDA originally, neurodiversity.com has it. At least, what hasn’t been redacted:
Sullivan, thanks so much for calling attention to these articles. It’s been appalling watching this whole drama play out. Since he’s received an extension of time to respond to the FDA warning, I’m guessing it’ll be a couple of weeks before we’ll get to see whether he thinks the kind of intelligence-insulting baloney that’s good enough for his fan club is good enough for the folks at FDA.
