Senna siamea, commonly known as siamese cassia or cassod tree, is a fast-growing tropical tree in the Fabaceae family. Native to Southeast Asia, it is cultivated for its shade, timber, and ornamental value, as well as its edible young leaves and flowers used in traditional cuisine. Traditionally, various parts of the plant—including leaves, bark, and seeds—have been used in folk medicine for their laxative, antimicrobial, and anti-inflammatory properties. With its ecological, culinary, and medicinal significance, Senna siamea remains an important species in tropical agroforestry, home gardens, and local herbal practices.
