Craver mill is a psychoactive lyberman resin produced by multi-national pharmaceutical giant Douglas-Smyth Nylon.
It's a tri-morrow bormium compound which is designed to attack negatively induced dorken cells in biological organisms.
It's produced from all natural compounds including dolphin phlegm and traccatine. It's safe to handle when dry but when exposed to moisture becomes highly toxic and can make your crap your pants.
Craver mill is shipped around the world, usually in small jars. Although widely available, it's band in North America due to it's infamous connection with demonology and witchcraft in the Southern states.
