ABSTRACT Cassia fistula belonging to the family Fabacae commonly known as Golden Shower, Amaltash. This plant is used in folk medicine to cure burns, constipation, convulsions, diarrhea, dysuria and epilepsy, to cure leprosy, skin dieseases and syphilis. Cassia fistula have a rich source of tannins, flavonoids and glycosides. Pharmacological activities include antidiabetic, antibacterial, antifertility, anti-inflammatory antioxidant, hypatoprotective, antitumor, antifungal activities. This article aims to provide a comprehensive review on Taxonomy, Botanical description, phytochemical constituents and pharmacological activities. Keywords: Pharmacological activities, Antidiabetic, Antioxidant, Antimicrobial.
