Cinnamomum Loureiroi, or Saigon Cinnamon (Vietnam)
 

Saigon Cinnamon has a strong, spicy cinnamon taste and high levels of oil content. Originating in Vietnam, this cinnamon admittedly makes a good first impression in terms of sheer aroma and taste. It tends to be spicy and strong, and sweet all at the same time. In Vietnamese cuisine, Saigon cinnamon is an important ingredient in the broth used to make a noodle soup called pho.
