This study was carried out to investigated optimum mixing ratio of Korean cultivation Salvia miltiorrhiza forproduction of functional oyster mushroom. Mycerial growth was slow at addition of Salvia miltiorrhiza, and significant differenceby increase of Salvia miltiorrhiza. Yields of fruiting body show the highest to 139.5g/850ml of medium which are addition 5g/bottle of Salvia miltiorrhiza but rapid decrease by increase of Salvia miltiorrhiza. Diameter of pileus and thick of stipes were higherat addition Salvia miltiorrhiza than those of the controls. Thick of pileus and length of stipes were the highest at addition 30g, and20g and 30g of Salvia miltiorrhiza. The L value of stipes were the highest at addition 20g and 50g of Salvia miltiorrhiza and theL value of pileus were the highest at addition 30g of Salvia miltiorrhiza, but there was no significant difference in the a-value andthe b-value.
