Flowers are rich sources of various medicinal active metabolites (Phenolics, alkaloids, terpenoids, essential oils etc), hence, they have strong antioxidant, anti-inflammatory and antibacterial properties. These could be used in pharmacognosy and health care products. Flowers are cultivated for ornamental and religious purposes, food, colour, dye, essential oil, cosmetics and pharmaceuticals. Flowers have great importance as temple offerings for worshipping the deities; which generates lot of floral waste, besides, floral waste also comes from floriculture as cut/ unsold flowers and floral refuge from industries which use flower as raw materials. This floral waste causes land, water and environmental pollution. This paper reviewed the current state of floral waste and its use in pharmacognosy and pharmacological applications.
