Chinese medicine has four qi of cold, hot, warm and cool, cinnamon as a Chinese medicine is warm in nature, and the use of cinnamon as a tea substitute is also warm in nature. Osmanthus fragrans is used in Chinese medicine as the flower of the plant Lignum vitae, family Lignaceae. Osmanthus can dissipate cold and relieve pain (relieve pain by removing cold from the body), warm the lungs and dissolve drinks (promote the flow of stagnant fluid by warming the lungs), and is often used to treat phlegm-drinking (a pathological product of impaired metabolism of fluid), coughing and wheezing, cold pain in the epigastrium (cold and painful sensation in the stomach and abdomen), menstrual cramps and dysmenorrhea, and intestinal winds with blood dysentery. People with solid heat syndrome and damp-heat syndrome should be cautious in taking cinnamon, and the adverse effects are not clear at the moment. The active ingredients of osmanthus in tea are limited, so it is not as effective as osmanthus in soup. It is recommended to take osmanthus tea under the guidance of a Chinese medicine practitioner.
