Ethnobotanical surveys reveal the crucial role of medicinal plants in the primary healthcare system of the Shan people in Myanmar.

Ethnopharmacological Relevance: The Shan people of Myanmar live under conditions of longtime social instability and public medical resources inadequate, which tend to strengthen the reliance on local traditional primary healthcare system. The documentation of this kind of resource, however, was rarely and inadequate to support any kind of dynamic trend evaluation. Being an ethnobotanical study, we conducted field survey in the Southern Shan State of Myanmar and aimed to 1) document the local plant species that adopted for primary healthcare purpose, 2) clarify how these species collectively address the broad range of primary medication needs for local people, and 3) lay foundation for dynamic trend evaluation of the role of local medicinal plants under this kind of social and cultural context.
