The Swat Valley of northern Pakistan, nestled within the Himalayan foothills, is a region of remarkable biological and cultural richness. Its indigenous communities have maintained a deep relationship with nature through centuries of traditional plant-based practices. This study investigates the ethnobotanical diversity, traditional uses, and therapeutic potential of medicinal plants utilized for managing diseases such as cancer, diabetes, and microbial infections.
Through field surveys conducted in 24 villages across Swat, and interviews with 85 traditional healers and elders, 152 medicinal plant species belonging to 66 families were recorded. Quantitative ethnobotanical indices including Use Value (UV), Relative Frequency of Citation (RFC), and Fidelity Level (FL) were applied to assess cultural significance. Berberis lycium (UV = 0.89), Rosa webbiana (UV = 0.81), and Thymus linearis (UV = 0.76) showed the highest citation frequencies, indicating their critical role in local healthcare. About 43% of the species were used for infectious diseases, 26% for metabolic disorders, and 18% for cancer and tumor-related ailments.
Preliminary phytochemical and molecular analyses confirmed the presence of alkaloids, flavonoids, phenolic acids, and terpenoids suggesting potential pharmacological applications, especially in anticancer drug discovery. This study highlights the urgent need to preserve indigenous knowledge systems threatened by modernization and environmental degradation.
By bridging traditional ethnobotanical wisdom with modern biomedical research, this work demonstrates how local plant knowledge can inspire innovative, culturally rooted, and sustainable therapeutic solutions, contributing to the global mission of biodiversity conservation and biocultural heritage preservation.
