One is pumice, a type of volcanic rock. It is specifically known as floating stone (fu shi). The other is the skeleton of a marine organism of the genus Costazia. It resembles coral; it is whitish yellow or light grey in color, but does not sink. It has a slightly fishy odor and a salty flavor. These substances
are fully interchangeable in the clinic.
