An ethnobotanical survey was conducted in Bac Huong Hoa, Quang Tri province, Vietnam. The Van Kieu ethnic group is knowledgeable about medicinal plants in the nature reserve, but this knowledge is poorly documented. This study aimed to record the use of medicinal plants, parts used, preparation, and delivery methods by the Van Kieu. Information was gathered through semi-structured and unstructured interviews from April 2016 to December 2023. The survey involved 93 informants aged 20–81, reporting 111 medicinal plant species from 102 genera and 46 families. Dominant families included Euphorbiaceae (10 species), Compositae and Leguminosae (9 each), Apocynaceae (7), Rutaceae, and Rubiaceae (5 each). Leaves (43.1%) were most used for medicine preparation, with decoction (49%) and oral administration (51%) being common methods. A total of 356 use reports documented plants like Artocarpus heterophyllus, Chromolaena odorata, and others as highly useful. Among 111 plants, three are on the IUCN Red List: Dalbergia tonkinensis (VU), Cinnamomum balansae (EN), and Aquilaria crassna (CR). Similar uses were found for 62 species, while 41 had different uses than listed in the Vietnam medicinal plants dictionary. Some plants demonstrated high cytotoxicity against human cancer cell lines, suggesting Bac Huong Hoa’s ethnomedicinal plants in Vietnam have potential anticancer agents. This research aligns with the Belt and Road Initiative’s focus on fostering ecological and cultural collaborations, emphasizing the conservation and sustainable utilization of biological resources for shared growth and environmental protection.

摘要

An ethnobotanical survey was conducted in Bac Huong Hoa, Quang Tri province, Vietnam. The Van Kieu ethnic group is knowledgeable about medicinal plants in the nature reserve, but this knowledge is poorly documented. This study aimed to record the use of medicinal plants, parts used, preparation, and delivery methods by the Van Kieu. Information was gathered through semi-structured and unstructured interviews from April 2016 to December 2023. The survey involved 93 informants aged 20–81, reporting 111 medicinal plant species from 102 genera and 46 families. Dominant families included Euphorbiaceae (10 species), Compositae and Leguminosae (9 each), Apocynaceae (7), Rutaceae, and Rubiaceae (5 each). Leaves (43.1%) were most used for medicine preparation, with decoction (49%) and oral administration (51%) being common methods. A total of 356 use reports documented plants like Artocarpus heterophyllus, Chromolaena odorata, and others as highly useful. Among 111 plants, three are on the IUCN Red List: Dalbergia tonkinensis (VU), Cinnamomum balansae (EN), and Aquilaria crassna (CR).
