Traditional markets in Vietnam are considered as important places for trading medicinal plants and also play a social role of exchanging traditional use of herbal medicine among different cultural and social groups at the local level. This study aims to identify and document medicinal plants used in 32 traditional markets of Son La province. Data were obtained through interviews and field observation method. A total of 167 informants include 13 herbalists, 49 herbal sellers, and 105 local people were interviewed. The study collected a total of 99 plant species belonging to 88 genera and 57 families. Identified plant species are used by local people for the treatment of 61 different diseases. Leaves, stems and roots are most commonly used either fresh, dried or by decocting the dried parts in water. In the study, the Relative Frequency of Citation (RFC) ranged from 0.02 to 0.44; the Use Value (UV) ranged from 0 to 0.84; the Informant Consensus Factor (ICF) ranged from 0.84 to 1; the Fidelity Level (FL) ranged from 44.44% to 100%. Villagers view and our observations confirmed that knowledge about the number of medicinal plants available in the study area and used by interviewees positively correlated with the threats on medicinal plants in the wild habitats. Illegal and unsustainable exploitation by the local people is a major cause of their depletion from nature.
