Cassia siamea, commonly known as yellow cassia or Siamese senna, is an evergreen tree native to Southeast Asia, particularly in the countries of Myanmar, Malaysia, Laos, Vietnam and Thailand. Known as a source of high-quality firewood, yellow cassia is also grown as an ornamental because of the bright yellow flowers it produces throughout the year. The different parts of yellow cassia can be used for various purposes. Its young fruits and leaves, for instance, are consumed as vegetables in Asia and are often used when making curry. The fruits are also useful for getting rid of intestinal worms and preventing convulsions in children. Meanwhile, the heartwood of yellow cassia is used as a laxative in traditional medicine and can be used to make a decoction for the treatment of scabies.
