Women's wellness in the mountains: An exploration of medicinal plants among tibeto-burman groups in Thailand.

Ethnopharmacological relevance: This study offers valuable insight into the traditional healing practices of women's healthcare within four Tibeto-Burman groups. By focusing on women's wellness, the research sheds light on the often-neglected yet significant contributions made by women in the field of traditional medicine. Aims of the study: The study seeks to address the gap of studies on the ethnobotany of women healthcare of the Tibeto-Burman groups in Thailand and to analyst the factors that could affect the diversity of ethnobotanical knowledge. Materials and methods: The study compiled data from 15 group-informants residing in 12 different villages. The information gathering process involved a combination of free-listing, semi-structured interviews, group discussion, and the walk-to-the-wood method. To analyze the data, the researchers used various methods such as use-reports, Relative Frequency of Citation (RFC), Relative Importance Index (RI), and Cluster analysis. Results: This study identified 200 plant species used in traditional women's healthcare practices, with leaves being the most frequently used part. Drinking was the most common method for internal use, while bathing and steam were the most emphasized for external use. Blumea balsamifera and Buddleja asiatica had high RI and RFC. Cluster analysis revealed that group-informants were divided by ethnicity and geographical location. Conclusion: This study contributes to the understanding of traditional healthcare practices among Tibeto-Burman groups in Thailand, with a particular focus on women's wellness. The results provide insight into the ethnobotanical knowledge of these communities and highlight the important role played by women in traditional medicine. The study underscores the need for continued research in this field to preserve and utilize this valuable knowledge.

Medicinal plant knowledge and its erosion among the Mien (Yao) in northern Thailand.

ETHNOPHARMACOLOGICAL RELEVANCE: We studied local knowledge and actual uses of medicinal plants among the Mien in northern Thailand, documenting traditional medical practices and its transfer between generations. AIM OF THE STUDY: With the assumption that discrepancies between knowledge and actual use represent knowledge erosion, we studied whether actual use of medicinal plants corresponded to people's knowledge of such uses. MATERIALS AND METHODS: We used local knowledge from four specialist informants as the domain for semi-structured interviews with 34 randomly selected non-specialist informants. We calculated informant consensus, use value, and fidelity level for each species and use category and performed statistical analyses with Kolmogorov-Smirnov tests, Pearson correlation coefficient, Spearman's rank correlation coefficient, and paired-sample t-tests. RESULTS: We found significant discrepancies between knowledge and actual use of medicinal plants. The number of known and actually used plants increased with increasing informant age and decreased with increasing years of formal education. CONCLUSIONS: Medicinal plant knowledge and use in these Mien communities is undergoing inter-generational erosion because of acculturation and interrupted knowledge transmission. Preservation of Mien medicinal plant intellectual heritage requires continued documentation concerning use, conservation, and sustainable management of this resource, which should be publicized to younger Mien.
