I believe that mercury will cause some kind of damage to any organ it touches, so the liver may have an advantage here because of it's ability to regenerate.

As for how much damage x-amount of mercury causes to the liver vs. kidneys: I've never seen any solid information/studies that address this, so it remains a good question that I'm sure will eventually be answered.

Just keep in mind that cilantro is not a chelator. It will move mercury from the CNS into the blood, but you will want a chelator present to bind it at the same time (DMSA/Sulfur/etc.).

Also, when detoxing via the liver, mercury will be thrown into the colon via the bile ducts. The colon will efficiently want to reabsorb some of this mercury back into the blood/body, so be sure to use Algin to prevent this redistribution.

Also, chlorella is famous because it's a source of sulfur. That's why it smells/tastes so bad. Just be careful because some people have a serious reaction to it. It worked for me, but start with only very small amounts to be sure you handle it.
