Spice with no Flavor or Aroma? I lost the label on a bag of some sort of spice, and trying to figure out what it is got me really curious of what it possibly could be and what use it could ever serve.

It is light brown, even slightly tan (reminiscent of natural sugar).
It has a very slight woody smell, with possibly an undertone of heat. 
It has no real taste, possibly woody again, and is slightly gritty. It makes me think of ground up bark, if 99% of the flavor was removed.

What spice does not have any flavor or aroma? This seems like an contradiction.

A stale, old one. The flavors in spices are volatile— they don't last forever.
