Diatomaceous earth is the finely ground carcass of fossilized phytoplankton.
It is actually the fossilized remains of diatoms, a type of algae found in water, that have accumulated on the bottom of oceans and lakes over a long period of time.
It is then harvested, milled, and ground into a talc-like powder, before being molded to create soil products.
Due to its porosity, it is an excellent natural material that also has filtration, heat retention, moisture absorption, and deodorant effects.
It is safe and eco-friendly and does no harm to the human body and the environment.
