A paSjav is a Klingon tree whose bark is cut into strips and eaten along with certain foods or else is ground up (like ngat) and added to some other kinds of foods. (It's occasionally just ripped off of the tree and eaten then and there.) Non-Klingons who eat too much paSjav tend to start coughing. Klingons think this is pretty funny and never seem to tire of it. tera' paSjav is a way to refer to cinnamon.
