title: [Study on processing technics of Tibetan medicine Nanhanshuishi].
abstract: OBJECTIVE
  To study the heat processing technics of Nanhanshuishi.
  
  
  METHODS
  To find the best processing technic, the single factor experiments and orthogonal experiments were designed basing on the processing technics summarized by consulting documents, scriptures and investigating some Tibetan hospitals, meanwhile, the content of Ca, Fe, Mn, Zn, and Cu in the processed Nanhanshuishi in single factor experiments and orthogonal experiments were detected.
  
  
  RESULTS
  The best processing technic of Nanhanshuishi was as follows: Nanhanshuishi was crashed to 10-20 mm in diameter, the ratio of the weight of Aconiti Kusnezoffii Radix and potassium nitrate was 1: 2, and the boiling time was 3 h.
  
  
  CONCLUSIONS
  The work in this article provided a basic processing technic data for clarifying the mechanism of processing and establishing the perfect processing technics of Nanhanshuishi.
