Bark is fragrant and can be used as a spice. It tastes similar to cinnamon from Sri Lanka, but it is hotter, less delicious and thicker than cinnamon. In North America, cinnamon powder is sold indiscriminately, whether from China or Sri Lanka.

There is cinnamon Eucommia tea to warm liver and kidney, dispel cold and relieve pain.
