It might just be you Bex, and some others with problems other than heavy metal toxicity complicating things.

Cilantro works great for me, others have had good experiences with it too, and adding DMSA to my cilantro routine is very effective for me.

Using DMSA alone doesn't work that well for me, it'll clear my blood of some stuff I think but I always end up getting a headache or on the verge of one when I use it alone. The cilantro always makes my head feel good. The store bought cilnatro doesn't compare to my fresh homegrown stuff though, I have to use twice as much at least and then of course I wonder about pesticides and other stuff that might be in it.

and then of course, not overlooking the liver flushes, parasite and colon cleansing which have also helped a whole bunch.

I really think you have to do the whole spiel.. colon cleansing, chelating, colon cleansing, chelating, chelating, parasite cleansing, liver flushes, colon cleansing, chelating chelating chelating, colon cleansing colon cleansing, chelating chelating chelating colon cleansing colon cleansing chelating chelating ... liver flushes, colon cleansing, chelating chelating

in that order more or less.
