Except when I used cilantro and chlorella for many months and experienced dramatic improvement in my heavy metal trouble without any of the doomsday predictions coming true. Actually, my improvement with cilantro was greater than when using Cutler. I'm also not the only one I know who has used cilantro/chlorella and experienced dramatic improvement.
The only time I had trouble with it was when I tried to use too much. I reduced the dose, and things returned to normal.
People should be careful with cilantro and not fall into the trap of taking too much because it's just a spice and it is therefore "safe" to take as much as you want on any schedule you want. Like any chelator, cilantro is potentially dangerous and people need to be careful to use small doses systematically.
