abstract: OBJECTIVE
  To study the use of medicinal plants by the Mien in Nan Province and their potential value in the primary healthcare of postpartum women. Also, to survey the medicinal plant resources present there.
  
  
  METHODS
  Free listing and interviews were used with four key informants (herbalists and collectors) to collect all qualitative and quantitative plant data. Semi-structured questionnaires were used to obtain information on the knowledge, attitude and practices of fifty-eight non-specialist informants. Transect walks of forest plots were carried out with herbalists to get more information on the status of the medicinal plants with regard to their habitat.
