Siamese cassia is an evergreen tree from South and Southeast Asia that grows up to about 18 m, with yellow flowers and pinnate leaves. It is grown mainly as a shade or windbreak tree and for its hardwood, and it is not normally kept as a houseplant.
Senna siamea, also known as Siamese cassia, kassod tree, cassod tree and cassia tree, is a legume in the subfamily Caesalpinioideae. It is native to South and Southeast Asia, although its exact origin is unknown.
This plant has medicinal value and it contains a compound named barakol. The leaves, tender pods and seeds are edible, but they must be previously boiled and the water discarded. They are used in Burmese and also in Thai cuisine where one of the most well-known preparations is kaeng khilek (Thai: แกงขี้เหล็ก).
