title: [The transition of psychotropic drugs in Japanese pharmacopoeia (JP) (Part 10). The study for transition of cultivation of valerianae radix].
abstract: Valerianae Radix (V.R.) had a large advantage throughout domestic and foreign markets before the Second World War. After the Second World War, many kinds of psychotropic pharmaceutics were imported from foreign countries. Therefore, the production of V. R. declined greatly in Japan. Now, V. R. are grown only in the Hokkaido area for the purpose of preserving the species. In spite of this situation, it is thought that V. R. may be useful as a sedative drug for aging society by its gentle action. Therefore, the cultivation of V. R.  and its quality improvement in Japan may be research subjects in the near future.
