The cultivation of Poria cocos on tree-stumps and logs, was first described at the beginning of the 13th century. Poria cocos has been used for medicinal purposes to treat physical and mental recuperation, promote diuresis, forgetfulness and physical weakening. The artificial cultivation techniques of P. cocos was reported in China in 1957. are reported. The basic study on morphological characteristics and artificial cultivation method of Poria cocos with pine tree log buried under ground were initiated by Rural Development Administration. To widen the utilization of harvested sclerotia of Poria cocos as new food stuffs, powder of the sclerotia were used for producing new soft drinks and supplemented to wheat flour to make functional bread. Last 30 years, the supply of P. cocos in Korea through cultivation could not meet the domestic demand, Korea collected P. cocos in the mountainous areas and also import the sclerotia from China. Since the domestic demand of the sclerotia in China increased, the price of imported sclerotia of P. cocos also increased. Recently, high-quality and high-yielding cultivation methods were developed in Gyeongbuk Agricultural Research and Extension Services (GARES). The new cultivation methods of P. cocos developed by GARES was to change traditional cultivation method from under ground to above ground cultivation house, and shortened cultivation period by half, and improved the quality of the sclerotia. Therefore, it is suggested that advanced new technology for production of sclerotia of P. cocos from under ground and above ground must be developed for fullfil the domestic demand of the sclerotia.
