Abstract：The method of peeling Fructus Gardeniae and using the seed of it began in the Jin Dynasty，and the theoretical discussion on whether to use Fructus Gardeniae with or without the peel began in the Yuan Dynasty. The manual methods of peeling Fructus Gardeniae include transverse cutting， longitudinal cutting， pounding， grinding and bumping， and so on， and the longitudinal cutting after wetting is the best. The main purpose of processing Fructus Gardeniae with ginger is to treat depression，vexation and vomiting，and pain caused by the heat constrain of stomach fire. Before the Yuan Dynasty，raw Fructus Gardeniae mostly used，and the Chinese medicine practitioners in Ming and Qing Dynasties had different opinions on whether to use raw Fructus Gardeniae or dry-fried one. During the process of dry-firing，both the whole Fructus Gradeniae and its fragment are hard to be dry-fired evenly，and only by separating the peel and seed，can they be dry-fired to brown respectively. Further researches on the peel and seed of the Fructus Gardeniae should be carried out，and the seed of the Fructus Gardeniae，a traditional medicinal processing variety，should be restored，and the processing technique of Fructus Gardeniae Praeparatus should be improved.
