Ethnobotanical study of edible underground storage organ plants in Youjiang District, Baise City, Guangxi, China.
Article in Journal of ethnobiology and ethnomedicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEdible underground storage organ (USO) plants are important components of traditional food systems and local healthcare, yet their ethnobotanical roles remain insufficiently documented in many regions. This study investigates the diversity, utilization, and ethnomedicinal significance of USO plants in Youjiang District, Guangxi, China.
methodsEthnobotanical data were collected in 2025 through semi-structured interviews, participant observation, and field surveys involving 60 informants, including key informants recognized for their knowledge of local edible plants. Plant specimens were collected and taxonomically identified. Quantitative ethnobotanical indices, including Use Value (UV), Fidelity Level (FL), and Informant Consensus Factor (ICF), were applied to evaluate the cultural importance and medicinal consensus of recorded species.
resultsA total of 50 USO plant species belonging to 24 genera and 13 families were documented, with Zingiberaceae as the dominant family. Native species accounted for 72%, and rhizomes were the most common storage organ type. USO plants were used across multiple categories, particularly as medicine (39 species), vegetables (24 species), condiments (20 species), and staple foods (18 species). The highest UV was recorded for Allium sativum L. (0.883). FL values ranged from 6.67% to 100%, and ICF values from 0.750 to 1.000, indicating strong agreement among informants. Most remedies were prepared from fresh materials and administered orally.
conclusionUSO plants in Youjiang District function as important biocultural resources that support local food practices and traditional healthcare. The high diversity of native and multifunctional species, together with strong ethnomedicinal consensus among informants, highlights the importance of conserving both plant resources and associated traditional knowledge. These findings provide a baseline for future nutritional, pharmacological, and sustainable utilization studies of culturally important USO species.
