HI there, yes there is a product called DMSA (available online) that many people use to both bind and remove their mercury. It is also used on children, so it is safe. There is, as with anything, the rare allergic reaction to it or intolerance, but most do ok.
You start on a very low dose and take it every 4 hours around the clock (according to Andrew cutler's guide lines, he is a biochemist and well versed on the science of mercury and how to remove it safely). You have to set an alarm to wake up at night to take th doses also.
You take it for about 3 days straight on this regime and then take a break of the same amount of time (e.g. 3 days on, 3 days off). And then start again and continue this cycle until mercury is reduced in your blood/urine and tissue.
It takes a few months to do this, but it's wise to, as using products like cilantro or alpha lipoic acid, which can cross the blood brain barrier is risky when you already may have too much mercury in your body area and need to reduce that first before the brain. Otherwise you risk further uptake into the brain.
But that's up to you, you may wish to continue with the cilantro but I wouldn't advise it. At any rate, DMSA will bind and remove if you use it according to the every 4 hour regime.
You can use it for as long as a week if you want, but most try every 3 days at first. If you do it for a week, you must also take a week off, so you can do one week on, one week off. whichever works for you.
The dose is about 25 mg to start or less. Some have to start as low as 6 mg (which of course means breaking up a capsule). It's a bit annoying, but sometimes a person needs to if their symptoms of detox are too overwhelming.
Here is a link where you can buy DMSA
http://www.vivagen.net/detoxprods.htm? It is about the 7th item down (the second bottle of DMSA). THe second one is the 25 mg one, which is the dose you'll want. You get about 120 capsules of 25 mg.
I hope this helps.
