Ethnomedicinal knowledge represents an important component of traditional healthcare systems, particularly in rural and tribal regions where medicinal plants are extensively used for treating various ailments. The present study aims to document and quantitatively analyze the ethnomedicinal plants used in Chittorgarh district of Rajasthan, India, with special emphasis on the Fidelity Level (FL) as a statistical indicator of informant consensus and medicinal reliability. A total of 50 ethnomedicinal plant species belonging to diverse botanical families were analyzed using recorded values of NP (number of informants citing a plant for a specific disease) and N (total number of informants mentioning the plant). The Fidelity Level was calculated to identify highly preferred species for specific therapeutic uses. Quantitative analysis revealed considerable variation in FL values, ranging from low consensus species to plants exhibiting very high fidelity (up to 100%), indicating strong traditional trust and specialized medicinal application. Statistical interpretation and graphical analysis were employed to understand patterns of disease treatment, plant selection, and usage concentration across categories such as fever, wound healing, digestive disorders, and respiratory problems. The study highlights key ethnomedicinal species with high therapeutic relevance and emphasizes the importance of preserving indigenous knowledge for future pharmacological validation and biodiversity conservation. The findings contribute to quantitative ethnobotanical research and provide a scientific basis for further phytochemical and clinical investigations.
