Grounding with a Earth box?


OK so help be understand something.   I understand the value of grounding equipment, but what is the value of having a woodbox with salt, earth, minerals etc  do for grounding?  How is supposed to work or be better?

You're missing my point.  This is not one guy making a box -  its an item sold by retailers.   My question is how does work and is better than true ground?  Otherwise, why is ay one doing it?
I put cat litter in a beer can with a wire and it works.

I can gear the difference...

some of this stuff is crazy ass snake oil.
So per the website https://www.entreq.com/products/ground-boxes-17667704

it supposes to lower the noise floor since the home electrical system is full of interference.
