Cassia fistula, commonly known as the golden shower tree, is a medium to large deciduous tree in the Fabaceae family. Native to the Indian subcontinent and Southeast Asia, it is widely cultivated for its striking yellow flower clusters and ornamental appeal. Traditionally, various parts of the tree—including pods, leaves, and flowers—have been used in folk medicine for their laxative, antimicrobial, and anti-inflammatory properties. With its vibrant blossoms, medicinal uses, and cultural significance, Cassia fistula remains an important and cherished species in tropical and subtropical landscapes.
