  RESULTS
  A list of medicinal plants including 10 species of jie-ji in local Tibetan areas is given, including their morphological pictures used for identification.
  
  
  CONCLUSIONS
  The origin of jie-ji is from 10 species of the Section Cruciata, Genus Gentiana (Gentianaceae). five species with dark blue flowers are used as jie-ji na-bao, the other five with white flowers are used as jie-ji ga-bao. Also, Gentiana macrophylla Pall. with dark blue flowers in the Section Cruciata, Genus Gentiana is not the original plant of jie-ji na-bao. The species endemic to the province are used as the original plants of jie-ji only in local Tibetan area of the province. Finally, the drug use of jie-ji in Traditional Tibetan Medicine is reasonable and it is efficacious.
