| Remarks | Dihuang which originates from Akayajiō (Jap. name) hardly has market value in Japan. In Nara Prefecture, only a few is cultivated in order to keep the lineage. Fukuchiyama No.1 has been developed by hybridization between "Kaiekeijiō" (Rehmannia glutinosa) and "Akayajiō" (Rehmannia glutinosa var. purpurea). In China, the fresh root of "Kaikeijiō" is called "Xiandihuang" and the dried root is called "Shengdihuang" (Jap. name: "Kanjiō"). "Shudihuang" is dried after steaming. "Shudihuang" is steamed with "Huangjiu", a kind of rice wine such as "Shaoxingjiu", or simply steamed. Then it is dried by daylight. This process, steaming and drying, is repeated 9 times. "Kanjiō" and "Shengdihuang" are applied for heat symptom complex as a drug to dispel pathogenic heat from blood. "Shudihuang" is applied for deficiency of vital energy as a drug for enriching the blood. | ||||||
