Ethnobotanical Use of Plants for Relieving Stress Among Hill Tribes in Northern Thailand: A Pilot Study
Abstract
Objective: To describe the ethnobotanical plants used to alleviate stress among the hill tribe communities in Mae Hong Son Province, Thailand.
Material and Methods: Data were collected from 3 hill tribe villages; 246 participants were enrolled based on the inclusion criteria: 1) aged 21 years or older, 2) having parents of Karen ethnicity, and 3) understanding the purpose of the study. The exclusion criterion was a request to withdraw from the research. Plant utilization was recorded and cross-referenced with voucher specimens. Taxonomic identification involved photographing and collecting all plant samples.
Results: The results show that 59.30% of participants were female, and the mean age was 49.47 years (S.D.=0.54). Half of them had no formal education (50.80%). The most commonly used plant part for stress relief was the leaf (35.80%). Participants reported using 20 plants (17 species) for stress relief. Herbaceous plants were the most common type reported, particularly Centella asiatica (used by 37.40% of all participants). Participants reported using various parts of Pinus merkusii for stress relief. The most common preparation methods included raw consumption, cooking, and boiling (oral consumption, 50-100 grams). Stress levels decreased after plant use; a Stuart–Maxwell test confirmed this change was significant (χ²=14.14, df=2, p-value=0.001).
Conclusion: The study highlights traditional knowledge of plants for stress relief in hill tribe communities, providing insights into culturally relevant therapies. However, limitations such as a small sample size and lack of a control group affect generalizability, emphasizing the need for further research on their therapeutic potential.
