| Remarks | - Based on histomorphological (presence of inner sheath fibers) and chemical (GC-MS comparison) studies, the original plant of "Koku-Ōren" which is kept in Shosoin Repository was determined to be "Huhuanglian" (胡黄連) of Picrorhiza scrophulariiflora. P. scrophulariiflora is distributed in Nepal, southeastern Tibet Autonomous Region, northwestern Yunnan Province and western Sichuan Province in China. It is the rhizome of this plant that is listed in the Chinese Pharmacopoeia. On the other hand, P. kurrooa is distributed in India, Pakistan, Sikkim and Nepal, and its rhizome and roots are used in Ayurveda as "Katuki" for jaundice, indigestion and fever. In addition, it is now being applied to acute viral hepatitis and bronchial asthma. - Even though it is stored in the Shosoin Repository, it was very expensive and not accessible to the general public. Thus, the Japanese sought alternatives, and Semburi was assigned to this one from the supplemental illustrations in the "Zhenglei Bencao" (証類本草). From the end of the Muromachi period (1333-1573) to the beginning of the Edo period (1603-1868), some scholars realized this was a mistake. This is how Semburi (Tōyaku), one of the most famous Japanese folk medicines, was developed. - "Huhuanglian" (胡黄連), from northeastern China and the Korean Peninsula, is the root of Jeffersonia dubia Benth. (Jap. name: Tatsutasō/Itomakigusa) of the family Berberidaceae and called "Xian huanglian" (鮮黄連). | |||||
