Volcanic Rock

Is volcanic rock good for all plants? I was reading a few posts about people looking for volcanic powder, and was wondering if it would be ok to use it in place of stones at the bottom of my flower pots, when re-potting houseplants? It sounds like a good way to use up the old volcanic rock. LOL

I have a bag of volcanic rocks for the old barbeque.
