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 wine is also a traditional gift for birthdays in China. It is also considered a medicinal wine in traditional Chinese medicine. Li Shizhen's "Compendium of" Materia Medica credits sweet osmanthus with "curing the hundred diseases" and "raising the spirit". Within China, cassia wine is associated with Xi'an and Guizhou, but production now occurs throughout China, including Beijing and at the Hong Jiang Winery in Hunan. Despite the name, the Chinese cassia tree is not used to flavor cassia wine. References to the osmanthus in Chinese literature and poetry are often translated as "cassia" because both trees were formerly known in China
