In the comics, the Xerogen Crystals are basically an alternative version of the Terrigen Crystals that "de-evolve" humans and inhumans into Alpha Primitives.

Elledy92 is right. The Xerogen Crystals were used to turn the humans into Alpha Primitives. There was nothing on the Marvel websites about it devolving Inhumans though.
