METHOD FOR PRODUCING FIRED PRODUCT OF FRESHWATER CLAM SHELL, AND COMPOSITION FOR AMELIORATING HEPATIC DYSFUNCTION WHICH CONTAINS SAID FIRED PRODUCT AS ACTIVE INGREDIENT

摘要

[Problem] To provide a method for producing a powdery composition comprising calcined calcium carbonate and conchiolin, of which the hepatic dysfunction-ameliorating effect has been already confirmed, simultaneously using a freshwater clam shell as a raw material. [Solution] A freshwater clam shell is burned at a heating temperature of 200 to 300˚C for a heating time of 20 to 60 minutes, and the resultant burned product is milled, thereby producing a mixed powder comprising aragonite and conchiolin.
