Ethnobotany, Traditional healers, Indigenous health


The purpose of this research was to study the diversity and the knowledge of utilization of medicinal plants of the Tai-Lao traditional healers in Chanuman district, Amnat Charoen province. This study was conducted during October 2020 – September 2021. The data was collected by purposive sampling. Semi-structured interview were used for interviewing 5 traditional healers.  The study found 74 species of medicinal plants belonging to 67 genera, 38 families. The most common medicinal plants found in Fabaceae are 10 species (14%), followed by 7 species of Rubiaceae (9%). Of these, the medicinal plants were used to treat a total of 22 diseases. The highest ICF is wound (ICF=1) followed by diabetes and hemorrhoid (ICF=0.66 each). Lysiphyllum strychnifolium (Craib) A.Schmitz has the most reported use value index (UV) of 1, followed by Tinospora crispa (L.) Hook.f. & Thomson)  had  0.80 of UV. The most medicinal plant parts used were roots, 39 species (52%), followed by leaves 23 species (31%). There were eight different preparation methods for curing by herbalists. The most common preparation method was decoction, with 57 species (77%). The homes garden was the primary source of gathering medicinal plants, with 50 species (67%), followed by community forests, 33 species (44%). The most habit of medicinal plants was shrubs with 33 species (44%), followed by trees with 18 species (24%).   The results of this study demonstrate that the various traditional knowledge of medicinal plants among Tai-Lao herbalists still exists. Nevertheless, traditional healers are fewer since there are no successors, and most of them are elderly. As a result, these knowledges may eventually be lost in the future. The government should promote the traditional knowledge to be accepted in all sectors to conserve and prevent the erosion of this knowledge.
