Brain chelation is the use of an agent that is able to cross the blood brainer barrier and escort the mercury out of the brain. I'd invite you to check out the link earlier that I gave and there should be more information on brain chelating agents and what they do.

There are only two agents that I know of that can do this - ALA (alphic lipoic acid) (which is an antioxidant) and cilantro (herb).

The problem with cilantro is, though it's natural, there is not a protocol in place in how to use it to ensure its safety with moving/removing mercury. If there is random movement of mercury, then mercury can go anywhere/everywhere, which can make things worse. They call this "redistribution". That's why a protocol is important, because it's not just what you use, but how it's used that can make all the difference.

Fortunately, ALA and the way it works is more understood, so a protocol by Andy Cutler has been put in place. Therefore, it can be used with more certainty/safety, as long as this protocol is adhered to. Which is what Cutler has promoted. Taking a dose every 3 hours around the clock for a few days on, then a few days off as a break and keep repeating this cycle until mercury chelation is achieved and the person gets better. E.g. 3 days on ALA (every 3 hours), then 3 (or more) days off as a break and repeat.

Any form of chelation can be risky, whether body/brain chelation, because both move mercury. It's not so much the chelation or the chelator itself, but the mercury and how it is moved around the body that causes the most problems as far as I'm aware. Though in some cases a person may indeed be sensitive to the chelating agent itself. However, in most cases, any problems/backfires are usually related to how the mercury has been moved and sometimes it can be too much, too fast, and/or the manner it's been done. Mercury can end up being moved into worse and more sensitive areas if it's just merely being stirred up or has no consistent back up doses to keep the blood levels of chelator more constant and even, which allows for more safer movement of the mercury.
