Cinnamomum cassia has a sweeter flavor than Indonesian cassia, similar to Saigon cinnamon, but with lower oil content. Cassia bark (both powdered and in whole, or "stick" form) is used as a flavoring agent for confectionery, desserts, pastries, and meat; it is specified in many curry recipes, where Ceylon cinnamon is less suitable. Cassia is sometimes added to Ceylon cinnamon, but is a much thicker, coarser product. Cassia is sold as pieces of bark (as pictured below) or as neat quills or sticks. Cassia sticks can be distinguished from Ceylon cinnamon sticks in this manner: Ceylon cinnamon sticks have many thin layers
Cassia leptophylla Cassia leptophylla Cassia leptophylla is a tropical tree species in the genus "Cassia", which is indigenous to Brazil. It is named gold medallion tree and has yellow flowers that bloom intermittently throughout the year, spawning seedpods that are square in cross section and rattle festively. Recognized by its thin green foliage with glossy green pinnate leaflets. The fruit is a long thin seedpod with four sides. "Cassia leptophylla" is native to southeastern Brazil. This tree does not have many uses, except as a decorative tree or as a laxative, something common to the "Cassia" genus. Seed is poisonous if ingested.
