Medicinal plants play a crucial role in primary healthcare among indigenous communities; however, systematic ethnomedicinal documentation of the Yao people in Lingyun County, Guangxi, remains limited. This study aimed to document the diversity, traditional uses, and cultural significance of medicinal plants used by the Yao community. Ethnobotanical data were collected through semi-structured interviews with 104 informants. A total of 172 species belonging to 135 genera and 73 families were recorded, with Fabaceae, Lamiaceae, and Asteraceae being the most represented families. Herbs were the dominant growth form, and whole plants, roots, and shoots were the most frequently used parts, typically prepared in dried form and administered orally. Fidelity Level (FL) values ranged from 6.67 to 100, with several species showing high consensus in therapeutic use. Informant Consensus Factor (ICF) values (0.778–1.000) indicated strong agreement among informants, particularly for musculoskeletal, skin, gastrointestinal, and immune-related disorders. These findings highlight the richness and consistency of ethnomedicinal knowledge among the Yao people and provide a scientific basis for future pharmacological research, conservation planning, and the sustainable use of medicinal plant resources.
