Her use of "natural" things, in this case, cilantro, probably poisoned her child. It probably enabled Hg to get across the placenta in a way that is similar to how it apparently moves Hg across the blood brain barrier--in both directions! I commented in some length to her post.
That story is a reminder about kicking up Hg from some location where it is not doing much damage and having it settle in a different location that is very vulnerable to it and which holds onto it very tightly, ie hormone receptors related to the stress response system.
