Traditional Uses of Combretaceae Species in Nong Bua Lam Phu Province, Thailand: A Study of Ethnomedicinal Practices
Main Article Content
Abstract
The Combretaceae family plays a crucial role in traditional medicine across various cultures, including Thailand. This study investigates the diversity, ethnomedicinal uses, and preparation methods of Combretaceae species in Nong Bua Lam Phu Province. A total of 18 species from three genera—Terminalia, Combretum, and Getonia—were recorded, with Terminalia exhibiting the highest species richness. To evaluate their medicinal relevance, the study applied Relative Frequency of Citation (RFC), Informant Consensus Factor (Fic), and Fidelity Level (FL). Findings indicate that species such as Combretum pilosum and Terminalia chebula are highly valued for treating cardiovascular, gastrointestinal, and skin-related ailments, with strong consensus among informants. Traditional preparation methods—including decoction, grinding, and soaking—reflect indigenous expertise in extracting bioactive compounds. These results underscore the cultural and therapeutic importance of Combretaceae species in the region. The study highlights the urgent need to preserve this ethnomedicinal knowledge in the face of environmental change and cultural loss. It also calls for further pharmacological research and conservation initiatives to validate and protect these valuable plant resources. The results contribute significantly to the understanding of traditional plant-based medicine in Thailand and reinforces the global significance of indigenous knowledge in promoting sustainable healthcare and biodiversity conservation.
