Saigon cinnamon

Saigon cinnamon (Cinnamomum loureiroi, also known as Vietnamese cinnamon or Vietnamese cassia and Quế Trà My or Quế Thanh or " Quế Trà Bồng" in Vietnam) is an evergreen tree in the genus Cinnamomum, indigenous to mainland Southeast Asia. Despite its name, it is more closely related to cassia (C. cassia) than to cinnamon (C. verum, “true cinnamon”, Ceylon cinnamon), though in the same genus as both. Saigon cinnamon has 1-5% essential oil in content and 25% cinnamaldehyde in essential oil, which is the highest of all the cinnamon species. Consequently, out of the three species, it commands the highest price.
