Vietnamese cassia has been considered as a local speciality since ancient time. It was used to be as precious as elephant占쏙옙 tusk or peafowl and used as an envoy gift. Compared with Tung Hing cassia of China and Vera cassia of Indonesia it has a more intense flavour and aroma and a higher percentage of essential oils. That is why Vietnamese cassia is particularly highly esteemed, bringing high export value and creating practical benefits not only for people but also for the State. It has been presented in almost 20 countries in the world, e.g India, Korea, Japan, Singapore, China, Thailand, United State, Bulgaria, Hungary, Holand, Poland, Germany, U.K, etc.
