What Wierd Ingredients Do You Use? Options

I want to kow what kind of wierd, or out of the ordinary ingredients you use in your powders, or oils? You don't have to put entire recipes as I know alot of people are secretive when it comes to their powders & oils, just some wierd single ingredients you may use to give your stuff a little oomph. Example, one ingredient I use in my cursing/war powder is powdered mosasaur tooth. I like to buy Dino fossils & petrified wood & fossilized plants & powder them & use them in my powders. Other out of the ordinary ingredients I've used are human bones & burned & powdered snake skin. So, I know some of you have SOME out of the ordinary ingredients you use, let's hear 'em ;-).

Well, when I need to powder a hard substance (bone, brick etc...) i take the larger pieces and put them inside one of those stretchy men's dress socks and then put that inside a regular athletic sock. Then I just take it outside, set it on a hard surface and pound on it with a regular hammer. The dress sock tends to hold the finer bits pretty well, but you can't pound on it too long as the sock will eventually get chewed up. But I found it reduces the size of the bits enough to make the mortar time easier work.
Hope this helps.
