Natural white and black cystoliths can be found dotting throughout the plant. Pipers produces crystoliths by expelling calcium oxalate to regulate excess calcium and (to a lesser degree) heavy metals buildup within the plant. These crystals also have exalic acid that helps deter herbivore pests. Crysts come out white and eventually oxidizes to black.
