Senna alata is an erect shrub with a height of 3-4 m, which is distributed in the tropical and humid regions. The pinnately compound leaves are oblong and composed of 6-12 pairs of leaflets. They have a rounded tip with a slight indentation in the middle. Flowers have bright yellow colors and are arranged in a vertical column and bloom from the base of the column.

 Phytochemical analysis has shown that the plant contains phenolics (rhein, chrysophanol, kaempferol, aloe emodin, and glycosides), anthraquinones (alatinone and alatonal), fatty acids (oleic, palmitic, and linoleic acids), steroids, and terpenoids (sitosterol, stigmasterol, and campesterol), alkaloids, flavonoids, saponins, and tannins. These chemicals attribute to its anti-oxidant, anti diabetic, anti-inflammatory, anti-allergic, anti-poison, antispasmodic, emollient, anticonvulsant, anthelmintic, laxative, dermatophytic, antibacterial, anti-fungal, antiviral, anti poison, wound healing, diuretic, carminative, hepatoprotective, and antihyperlipidemic properties.
