EDTA...As I recall, we used that as a buffering agent in chem class. Well, something when we were doing quantitative analysis.

EDTA has a number of chemical properties, including an attraction for heavy metal ions with which it readily binds. It is this property that recommends it for use as a chelating agent, a class of chemical compounds that are supposed to do just that. However, the value of this "therapy" is questionable, and EDTA has other properties that may make it dangerous in high doses.

It's also used as a buffer for acid/base titrations, if I recall my quantitative analysis.

My question is why the heck are they trying to treat autism with EDTA? It just makes no sense.
