Zincum Metallicum has been showing up in tests now, this suggest that zinc is bound to minerals in the body and Klinghardt considers zinc a huge issue since it binds with Mercury.
Perhaps the way to look at this is the same as iron, before IP6 we had Anemia show up. This is now fixed by taking IP6. How can you fix an iron deficiency by taking something that chelates iron? Simple, the iron swaps an ion and turns into rust, perhaps the body stops/slows iron absorption since there is already too much rust.
Same thing may apply to Zinc; this is why both Zincum Metallicum and Zinc supplementation are reactive…
