The current study intended to document weed plant species frequently found in wheat fields and used by local community in traditional ways as food and ethno-medicines.

Results: We reported a total of 75 weed species belonging to 58 genera and 29 families, commonly consumed by the local communities. Floristic composition reveals Asteraceae as the dominant family having contribution of 14 species to the total, followed by family Lamiaceae (8 plant species) and Solanaceae.

These important plant species may serve to guide developmental initiatives aimed at sustainable and culturally local projects. The results emphasizing the need for phytochemical studies to further validate their efficacy
