Among the many bioactive compounds present in various plant parts, Juglone has been reported a significant anti-cancer compound in treating deadly cancer. This systematic review describes the significant knowledge and traditional information collected on ethnomedicinal uses, phytochemistry, habitat, macro-morphology, area of distribution, and pharmacological importance.
Background: Medicinal plants are used for different purposes and in diverse uses of human beings. Medicinal plants have played key roles in the lives of local peoples living in these biodiversity rich regions by providing products for both food and medicine. A study was conducted in hill station of District Ramban (J and K) in order to check the present status of medicinal plants diversity their abundance and for suggested utilization measures for residential peoples of the area.
