Remarks Listed in the Japanese Pharmacopoeia 18th ed.
Since ancient times, shengjiang, in Chinese Traditiona Medicine, has been representing fresh ginger, and ganjiang means dried one. That is, dried shengjiang (or ganshengjiang) in Chinese drug market indicates ganjiang in Kampo. Then ganjiang in the market means dried, after steamed, shengjiang. It can be called processed one. In China, in contrast, fresh ginger is shengjiang and dried one is ganjiang.
In addition, there is Paojiang which is a processed medicine. Paojiang is made as follows. First of all, the clean sand (gefen, huashifen) should be into a pan and heated at strong fire. The dried unpeeled shengjiang is added in and mixed them until the surface swells and the color turns to brown. Then it is picked up and cooled in air.
